10x: Product, team and how it was built

The two founders first ran an AI calling agency for any industry, which barely covered costs and lost customers. In January 2025 they narrowed to one niche, allied-health clinics on one practice system, and built deep booking integrations and local-accent voices for it. The co-founder said that customers called the first price cheap, so they raised it.

In the United States many medicines need the insurer's approval before the pharmacy can fill them, and that approval still means forms, faxes and phone calls. The two founders had worked at healthcare software startups and built a system that reads the insurer's rules and the patient's chart and does the form work. The Lean AI Leaderboard listed it at US$6 million a year with 5 employees in March 2025.

One founder's mother is a doctor, her clinic was the first user, and the founders say they spent years inside clinics before building. The founders say that, instead of one narrow tool, their engineers assemble reusable workflow blocks for each practice in days, so a practice can start with one painful task and add more. The founders said in June 2026 that 80% of growth came by word of mouth.

The three founders ran a dental marketing agency and their own call center for two years before they built the product, so they knew where clinics lose patients: calls that go to voicemail after hours, and insurance questions that need a call back. They connected the voice agent to the clinic software that already holds the calendar, and added live insurance verification, which they say no other system did during the call.

The founders had worked inside healthcare billing before, so they knew that insurance follow-up calls are a large, repetitive and expensive part of the work. A voice model can now hold this kind of short, scripted business conversation. The company sells to health systems and billing firms through pilots, and the founders said in November 2025 that every pilot had become a paying customer.

The founders say that setting up this kind of database by hand takes companies two to three months per trial, and that clinic staff spend hours typing records into it. Harbor turns the protocol into a draft database in about 10 minutes and the paper records into form entries with a confidence score for each value, so a small sponsor can start a study in days.

It began in January 2023 as an easy web interface for animation with Stable Diffusion, when the alternative was an open-source library that only programmers could run. Three months later the founder rebuilt it for one group of customers: musicians, who need a video for every song they release and cannot pay a film crew. He calls this the best decision he made.

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.

A developer in Bangalore formed a company with an American YouTuber who already had an audience of people who want faceless channels, so customers paid from the first day. Affiliates receive 33% of every payment and brought about a tenth of all revenue, and Meta ads brought more. Nobody could use the product without paying, so no free user consumed paid AI models. Verified revenue reached about US$85,000 a month for six months, and then fell by half.

It appeared in January 2023 inside Google Slides, a program where people already work, when writing slides from one sentence was new, and users showed it to each other without paid advertising. A blog about presentation topics then brought about 80% of new users from Google search, by the founder's account. Both channels weakened: search traffic fell, and Google added the same function to Slides. The verified total is real, and so is the fall: monthly revenue fell by half between February and July 2026.

Four founders, two of whom had built the drinks-delivery start-up Winelivery, looked for a profession that works with a large, fast-changing body of rules and had not yet adopted AI, and chose Italian accountants and labour consultants. They tested a first version with practitioners and sold monthly subscriptions. In October 2025 TeamSystem, an Italian maker of software for accountants, bought the majority of the company; its press release said Normo.ai had €1.3 million of revenue in 2025.

A studio portrait needs a photographer, a booking and days of waiting. AI SuitUp sold the same result, a photo for LinkedIn or a résumé, for a one-time price from early 2023, with a money-back guarantee on the larger packs. It narrowed the offer to one use, professional headshots, and then built a landing page for almost every profession and a version for company teams. Stripe records US$648,649 of payments in total, but only US$35,743 of it in the last 12 months, so most of the money came in 2023, 2024 and 2025.

The founder had worked as a screenwriter and knew which part of the job is tool work: the page format, and keeping characters and scenes consistent across a long draft. He built the editor around that work and kept the AI in the role of a helper. He says Claude Code wrote all the code. The beta grew through invite codes that users earned by posting about it, and monthly revenue rose from US$5,136 in May 2026 to about US$46,000 in August and in September.

It took a narrower job than the general AI design tools, mobile apps only, for people who build apps without design skills. The three founders reused what they had learned from four earlier design tools, built it in three weeks, and showed finished designs on X before the launch. Each new Gemini model gave them a better result and a new demo to post.
