Which small SaaS ideas won't disappear in two years?

Is AI actually killing small SaaS right now?

AI is killing some small SaaS ideas already, especially products whose entire job can now be reproduced inside ChatGPT, Microsoft 365 or another large software platform.

The vulnerable layer is getting easier to see. Microsoft now lets SharePoint users create custom agents directly from a site, document library or selected files. Every SharePoint site can also have a ready-made agent that answers questions about its content. A few years ago, “chat with your company documents” was enough to support a standalone SaaS pitch. Today, Microsoft can put essentially that capability inside software companies already pay for.

The same pressure applies to text generation, meeting summaries, document extraction, simple classification and basic automation. These functions remain useful, but usefulness alone does not protect the vendor selling them.

At the same time, the current vertical-SaaS numbers look nothing like an industry being wiped out. Stripe and Tidemark studied more than 200 vertical SaaS businesses and found companies offering several products growing 21% faster than single-product businesses. More than half of the vertical platforms in their dataset had already launched some form of AI product, and 87% of those companies were monetizing it.

That gives us the first important split. AI is making individual software features easier to copy while many companies that own the surrounding business workflow are getting stronger.

For a small founder today, “Can AI do this task?” is a useful first filter. If the whole product disappears once the answer becomes yes, the idea is fragile.

Why can a useful SaaS product still disappear?

A useful SaaS product can disappear when customers can get most of the same value from software they already have.

Take a product that rewrites sales emails. Customers may genuinely like it and save time with it. The problem appears when HubSpot, Gmail, Microsoft, ChatGPT or the customer's existing CRM produces sufficiently good drafts at no meaningful extra cost.

Now compare that with software that receives settlement files from several marketplaces, matches thousands of transactions against invoices, identifies discrepancies and records how each exception was fixed.

AI can improve the second product too. It can classify mismatches or suggest the likely explanation. But somebody still has to determine whether the books and the actual money agree.

Demos tend to reward visible features, which can make this distinction easy to miss. Durability often comes from the ugly work behind them: stored history, integrations, exceptions, permissions, recurring rules and tasks that must be completed correctly.

So we should be suspicious of ideas where the customer can say, “This is helpful, but we could live without it.”

The stronger opportunities usually produce a different reaction: “If we cancel this, who is going to do all of that?”

Does boring SaaS really survive longer?

Boring SaaS survives extremely well when it handles work that keeps coming back every week, month or year.

Construction software gives us a good real-world test. Procore reported gross retention of 95% in its latest available quarterly filing, unchanged from the previous year. Its total customer base increased only 4%, yet customers spending more than $100,000 annually increased 14%. Companies were not merely keeping the software; larger customers were embedding more of their operations in it.

There is nothing magical about construction software itself. The useful clue is what customers are storing and doing inside it: project information, budgets, approvals, contractor coordination, documents and work history.

Software attached to a recurring operational process has another advantage. Tomorrow's work creates tomorrow's reason to open the product. A social-post generator must repeatedly convince users that its output is worth paying for. An inspection system gets another job automatically whenever the next inspection becomes due.

“Boring” works as shorthand only when the underlying job has persistence.

A generic database for small companies can still churn heavily. Software tracking a mandatory inspection that customers must repeat every year has a much better reason to exist.

Small SaaS idea	What keeps demand alive	Two-year durability
Generic AI writer	User preference	Low
Generic dashboard	Convenience	Low
Equipment inspection records	Recurring inspections	High
Contractor compliance tracker	Certifications and deadlines	High
Marketplace reconciliation	Money has to reconcile	High
Generic task manager	Habit and preference	Low to medium

Are vertical SaaS ideas safer than horizontal SaaS today?

Yes. For a small founder, narrow vertical SaaS is currently one of the best places to look because one industry can give the product a much deeper job than a generic tool gets.

The latest Stripe and Tidemark benchmark makes this unusually clear. Across more than 200 vertical SaaS companies, multiproduct businesses grew 21% faster than single-product companies and had roughly five percentage points better net revenue retention. The median addressable market in their sample rose from about $250 million for a single product to $513 million as businesses expanded into additional products.

The interesting part for a small SaaS founder is how that expansion happens.

A fire-protection contractor does not only need inspection reports. The company also schedules technicians, records equipment, tracks deficiencies, sends quotes, stores certificates and invoices customers.

A dental laboratory does not only track cases. It also handles approvals, remakes, shipping, dentist communication and billing.

Once we understand one profession deeply, adjacent product ideas stop being random guesses. They appear in the workflow naturally.

That is much harder with horizontal SaaS because “small businesses” do not share one detailed workflow. A plumber, dental laboratory and recruitment agency may all need a CRM, but the important work around that CRM is completely different.

The best niches can therefore look almost comically specific. “Software for contractors” is broad enough to attract dozens of large competitors. “Certificate and deficiency tracking for independent fire-safety contractors” gives a small company somewhere much more realistic to start.

Which compliance SaaS ideas are hardest to get rid of?

Compliance SaaS is one of the strongest small-SaaS categories now because customers can replace the vendor, but they cannot cancel the obligation.

Electronic invoicing shows how quickly this can create new software work. Belgium requires structured electronic invoices for nearly all domestic B2B transactions covered by the rule. The invoice has to be structured data rather than simply a PDF sent by email.

That produces much more specific problems than “businesses need invoicing software.”

Some accounting systems will generate valid invoices but handle rejection workflows poorly. Companies working across several countries need different rules. Accountants need to find exceptions across multiple clients. Older ERP systems need connections to newer networks. Someone needs to preserve what was sent, received, rejected and corrected.

Those are better small-SaaS opportunities because the regulation keeps producing work after the initial invoice has been generated.

The same pattern appears in certification tracking, mandatory equipment inspections, vendor documentation, privacy requests, employee credentials, food-safety records and industry licensing.

AI can read the rules and fill fields faster. It cannot make the legal obligation vanish.

There is one catch. Broad compliance platforms become complicated quickly. A solo founder probably does not want to maintain every employment law in Europe or every tax rule in the United States.

The more realistic business is narrower: one obligation, one industry, one jurisdiction or one painful step around an existing compliance system.

Will accounting and reconciliation SaaS still be worth building?

Yes. Reconciliation is particularly durable because AI can help explain mismatches without eliminating the need to make the numbers match.

A Shopify seller might receive customer payments through several methods, pay marketplace fees, issue partial refunds, handle chargebacks and receive settlements that combine hundreds of transactions. QuickBooks can contain the accounting records while Shopify and payment processors contain the operational records. The business still needs to know why those systems disagree.

The same headache appears in agencies reconciling retainers, property managers matching rent payments, franchise groups calculating royalties, marketplaces paying suppliers and businesses calculating commissions.

This category has an attractive property for small SaaS: the customer can often measure the pain in money and hours.

“Save time with AI” is becoming a crowded pitch.

“Here are the 37 transactions responsible for the $18,420 gap between your marketplace payouts and your ledger” is much easier to value.

AI will probably make these products better. Classification that once required rigid matching rules can increasingly handle messy descriptions and unusual exceptions. Yet companies still need approvals, an audit trail and a final answer that can be trusted.

That makes reconciliation a good example of a SaaS category where better AI strengthens the product instead of destroying the reason to buy it.

Is scheduling SaaS already too crowded?

Generic appointment scheduling is crowded, but specialized operational scheduling still has plenty of room because many businesses are solving something far more difficult than finding an empty slot.

Imagine a company with 12 field technicians. One employee is certified for a particular job. Another cannot work in a certain zone. Some appointments take three hours. Emergency calls can displace routine work. Equipment has to be available. A customer may have a contractual response deadline.

Google Calendar can display the result, but the hard part is deciding what the schedule should be.

This creates small opportunities around inspection companies, home services, equipment maintenance, mobile healthcare, laboratories, specialist cleaning, rental companies and many other industries.

The useful idea is usually narrower than “scheduling software for electricians.” A founder could handle emergency rescheduling for one trade, recurring inspection routes, technician-certification matching or appointment sequencing around equipment availability.

Physical work gives these products extra protection because a bad software decision has an obvious consequence in the real world. A technician drives to the wrong place. Equipment sits idle. An inspection expires. A job misses its promised window.

Those problems remain expensive regardless of how good general-purpose AI becomes.

Are systems of record still a good small-SaaS idea?

A narrow system of record remains one of the safest SaaS structures because every month of usage adds information the customer needs to keep.

Consider software that tracks one category of industrial equipment. After two years, the database might contain each machine's installation date, maintenance history, photos, warranties, breakdowns, inspections and replacement parts.

A competitor can copy the interface surprisingly quickly.

The customer's two years of operating history are harder to reproduce.

Procore's 95% gross retention is useful here because construction projects create exactly this kind of accumulated state. Customers keep adding projects, records and collaborators, so leaving the software involves much more than learning another interface.

A tiny SaaS does not have to become the central operating system for an entire company. That ambition can actually make the initial product worse.

Owning one important object can be enough.

A laboratory sample has a history. So does an insurance claim, permit, machine, safety inspection, vehicle, property defect, customer certification or recurring maintenance contract.

We would especially like ideas where people currently maintain that history in a spreadsheet plus folders plus email. The fragmented record is a clue that nobody has fully claimed the workflow yet.

Can integration SaaS survive when AI agents can connect apps?

Simple app-to-app automation is getting easier, while integrations that have to stay correct can still make excellent businesses.

Microsoft's current agent tools show how low the basic barrier is becoming. SharePoint users can create agents themselves, and Copilot Studio agents can be published back into SharePoint for employees to use. Building an intelligent layer over existing workplace data is steadily moving closer to a native feature.

That will hurt SaaS products whose entire value is a simple trigger such as “when a form arrives, copy these fields into another application.”

Production systems get messier.

Authentication expires. One platform changes its API. The same webhook arrives twice. An accounting system and CRM define “customer” differently. Records need deduplication. Failed jobs have to retry. Somebody has to decide what happens when a required field exists in one system but not the other.

A useful integration product owns those ugly cases.

For example, “sync QuickBooks and a CRM” is thin.

A system that moves approved change orders from construction software into accounting, maps them to the correct project and account, prevents duplicates, flags exceptions and confirms that both systems still agree has much more staying power.

As AI makes the initial connection easier, reliability becomes a larger share of what customers are actually paying for.

Which monitoring SaaS ideas can still work now?

Small monitoring SaaS can work very well when the thing being watched is cheap to monitor and expensive to miss.

There are thousands of versions of this problem: expiring professional licenses, missing marketplace listings, failed backups, broken data feeds, domain expirations, inventory anomalies, unpaid invoices, supplier price changes, API failures, expiring insurance documents and regulatory deadlines.

A product charging $30 or $100 a month does not need to automate an employee's entire job. Catching one costly failure can justify a year of fees.

This gives monitoring SaaS a cleaner job than many AI tools. The customer does not particularly care how clever the software feels. They care whether it catches the event reliably and tells the right person early enough to act.

AI still helps. It can group similar incidents, decide which anomalies look suspicious and summarize what changed.

But monitoring requires persistent observation. A user cannot replace that by opening ChatGPT once a week and asking, “Did anything go wrong?”

A strong small-SaaS question is therefore: what do businesses repeatedly check because nobody trusts that they will hear about the problem automatically?

That manual checking habit can point to a very durable product.

Will document SaaS disappear because AI can make documents instantly?

Document generators are becoming weak standalone ideas, while the workflows around important documents remain much harder to replace.

Writing an inspection report, customer proposal, contract draft or certificate is getting cheaper every year. General AI already handles much of the first draft.

The complicated part starts around the document.

Which data belongs in it? Which version was approved? Who needs to sign? Were required attachments included? Did the customer respond? Was a revised scope accepted? Where should the final version be stored? Does another system need the information afterward?

Electronic invoicing makes the distinction easy to see. Belgium's current B2B requirement centers on structured electronic invoices that machines can process. Producing something that visually resembles an invoice does not satisfy the workflow.

The same principle applies elsewhere.

An “AI proposal generator for roofers” can be copied quickly.

A roofing workflow that turns an inspection into a scope, records customer revisions, collects signatures, requests a deposit, converts accepted work into a job and exports the correct information to accounting has many more reasons to remain installed.

The PDF may eventually become the least interesting part of the product.

Is SaaS tied to customer revenue safer?

Usually, yes. Products that help a business collect money, complete billable work or recover lost revenue have a much easier time defending their subscription price.

Toast is a useful large-scale example of how powerful this becomes. The company ended its latest full reported year with about 164,000 restaurant locations, up 22% year over year. Its annualized recurring run-rate rose 26% to roughly $2.05 billion, split almost evenly between subscriptions and payments. Quarterly gross payment volume reached $51.4 billion.

The interesting part is the coupling. Restaurants use the software while selling food, and Toast participates directly in the transaction flow.

The vertical-SaaS data shows the same pattern across a wider sample. Stripe and Tidemark found that payment adoption across their dataset increased from an average 27% attach rate to about 40% in a year. About a third of surveyed companies with payments had even made payments mandatory, and those companies showed higher net revenue retention.

A small SaaS founder does not need to process billions in payments to use this principle.

Failed-payment recovery, quote follow-up, deposit collection, commission checking, invoice escalation, marketplace payout matching and job-to-invoice verification all sit close to money.

A customer may cut a “productivity tool” during a bad quarter. Software visibly helping recover $12,000 of otherwise missed revenue gets a different conversation.

Small SaaS idea	Customer sees the value as
AI meeting summaries	Time saved
Generic writing tool	Convenience
Failed-payment recovery	Revenue recovered
Quote follow-up	Jobs won
Commission reconciliation	Money calculated correctly
Invoice exception handling	Cash collected correctly

Which SaaS ideas look safe today but could disappear fast?

Generic AI wrappers, document chatbots, basic dashboards, meeting-note products and simple one-step automations are among the riskiest small-SaaS bets today because major platforms are absorbing their core capabilities unusually quickly.

SharePoint is a good warning. Microsoft now gives sites ready-made agents and lets editors create more agents from selected company content. An entrepreneur can still make a better document assistant, but “we connect AI to your internal files” is no longer much of a product boundary by itself.

Generic writing tools face the same pressure from general AI. Simple reporting tools increasingly compete with native analytics and natural-language queries. Basic automation has to compete with incumbent suites as those suites add agents and workflows of their own.

None of these categories will literally vanish. Some companies have distribution, brand, proprietary data or specialized workflows that keep them valuable.

For a new small founder, however, the odds are worse. The product needs to win while standing exactly where large platforms are adding functionality fastest.

Platform apps deserve a little more nuance. Shopify, accounting and CRM ecosystems can still be excellent distribution channels if the app solves an enduring business problem. A tool handling a country's strange tax workflow or a niche wholesale process can survive even if Shopify adds another hundred native features.

The dangerous apps exist mainly to patch an obvious missing button in the host platform. Once the button arrives, the business loses most of its reason to exist.

Idea	Biggest threat over the next two years	Risk
Generic AI writer	General AI keeps improving	Very high
“Chat with your PDFs”	Native platform agents	Very high
Basic meeting notes	Suite bundling	High
Simple analytics dashboard	Native AI analytics	High
One-step app automation	Agents and built-in workflows	High
Industry compliance workflow	Obligation keeps recurring	Low
Financial reconciliation	Exceptions keep recurring	Low
Field operations system	Physical work continues	Low

How narrow should a small SaaS idea be?

A strong small-SaaS niche can start surprisingly narrow as long as the same customer has several nearby problems.

The latest vertical-SaaS benchmark is useful again here, but for a different reason. Stripe and Tidemark found that moving from one product to several more than doubled the median addressable market in their sample, from roughly $250 million to $513 million. Multiproduct companies were also growing 21% faster.

That suggests founders do not need to capture an enormous horizontal market on day one.

Suppose 8,000 inspection businesses share one miserable workflow. The first product might only track certificates and renewal dates. Once customers trust it, the same company could handle inspection scheduling, equipment history, deficiency quotes, technician qualifications and invoicing.

Starting with “business-management software for trades” would force a tiny company to compete across all of those functions immediately.

The narrower version lets the founder become unusually good at one annoying job first.

The best evidence often sits inside businesses already. Look for employees maintaining an unofficial spreadsheet beside expensive software, sending themselves reminders, exporting CSV files every Friday or copying the same data between portals.

Those workarounds tell us where existing products stop.

A content-planning spreadsheet is interesting but weak.

A spreadsheet containing 600 pieces of equipment, inspection dates, certificate numbers, locations and renewal deadlines is much closer to a product specification.

So which small SaaS ideas are most likely to survive the next two years?

The safest small SaaS ideas today are compliance workflows, financial reconciliation, narrow systems of record, specialized field operations, high-value monitoring, revenue-adjacent tools and integrations where correctness matters more than simply moving data.

We can be fairly confident about that conclusion because several different kinds of evidence point the same way.

General software platforms are rapidly absorbing easy AI features. Microsoft can already put agents directly inside SharePoint. At the same time, vertical software remains sticky: Procore recently reported 95% gross retention, while Stripe and Tidemark found faster growth and better retention among platforms that deepen their role across a customer's workflow. Payments are also becoming more tightly embedded in vertical software rather than less so.

For a small founder, the most interesting opportunities are therefore concrete and slightly unglamorous: reconcile payouts for one type of seller, track certifications for one profession, monitor a costly failure for one industry, manage inspection history for one type of equipment, handle one messy cross-system workflow or connect scheduling to the constraints of real field work.

Two years from now, AI will almost certainly perform more of the work inside these products. That's fine. A reconciliation tool should use better AI. So should compliance software, scheduling software and monitoring software.

We just want the customer problem underneath the AI to still be there.

The strongest small SaaS idea has a simple property: even if every AI model gets dramatically better, somebody still has to reconcile the money, pass the inspection, collect the payment, renew the certificate, preserve the record, schedule the technician or fix the failed process.

Those responsibilities are where we would build.
