ISMS Copilot: Revenue, team and how it was built

Solo founder · sold 17 months after launch

It solved one narrow and repeated task that every company has at the end of each quarter. The task is to find all invoices and give them to the accountant. It read the invoices where they already were, in the inbox and on supplier websites, instead of asking people to forward them. It also let customers write their own checking rules in plain language. Stripe data shows monthly revenue rising from US$12,631 in November 2025 to US$18,970 in January 2026.

The product goes where the customers already are. A shop owner does not install a new app or learn accounting software. Instead, the owner writes into a chat. The founder wrote of having worked as a data scientist at a microloan company and of running a café. So the founder knew both the bookkeeping problem and the reason banks ask for records.

The founder, a digital nomad, had collected more than 1,000 receipts from many countries to track his own spending. He built the app for that use. It reads every line item instead of only the total, which matters for travellers with receipts in foreign scripts and currencies. Small, steady releases widened the market: 25 versions between 21 January and late October 2026. A translation of the app into 52 languages did the same, without a team.

It serves one narrow job, turning a statement PDF into clean rows, and it grew through pages written for single banks. The founder wrote in March 2026 that almost all clicks come through those bank pages. A free tier and a small credit pack let people try it before they subscribe.

It does one narrow job and returns the same fields for every document. A developer or an automation builder can call it without writing a parser. It sells credits by the page, and a credit pack needs no subscription. Revenue is small, and the verified record shows it falling from its January 2026 peak.

It picked work that large regulated companies had failed to automate for years and that tolerates almost no errors. Instead of letting a model decide each step, it turns the expert's procedure into fixed program steps. This makes the result predictable and cheap to run. A few large customers, sold directly, can pay for a very small team.

It launched the obvious application of a new model within weeks, with a pricing page on the first day. The founder built the parts around the model instead of a model, so every model upgrade improved the product for free. Then it moved from a consumer toy to business customers who stay.

It reached people inside the chat app that they already open all day, so capturing an idea on a phone took one voice note. It aimed first at Notion users, whom the company told that ideas get lost on the phone. Ads on Facebook and Google then paid for fast growth in early 2026. The founder stopped them in August 2026 because the costs were larger than the revenue.

A normal chat window is one long thread, and a side question either breaks that thread or is never asked. The founder sold a fix for that one problem to heavy AI users. The subscription version earned little; the one-time licence that followed sold to many buyers, and Stripe data on TrustMRR shows US$131,070 in total. Sales then fell, because each one-time buyer pays only once.

The founder had written a marketing blog for ten years, so his own readers bought on the first day. He built the first version in 8 weeks with the no-code tool Bubble, because he had no money for developers. He sold one thing that the model makers do not sell: all of their models in one subscription.

A founder who had sold courses since 2022 built the email tool that he wanted for himself, and priced it by emails sent. His own newsletter was the first test of it, and the product now lets AI agents run an account.

The founder built a tool that he wanted for himself as a runner. He trained with a human coach from late July 2025 and stopped a marathon at kilometre 32. The product keeps what he valued in that coaching: varied sessions, pace ranges and a plan that follows what he runs.

The two founders built it first for their own SaaS products and Shopify apps. The reason was that they had to keep one support workspace open for every product and felt they had to answer at night. They then opened it to other founders with the same problem, with unlimited projects on every plan and a fixed price per team size.

Started small, grew after funding · sold 17 months after launch

The founders built it for their own problem. An app of theirs gained 20,000 users overnight. They did not know who those users were, so they built an AI that could interview them. The company later said it grew its annualized revenue 15 times in nine months.
