Ardent: Product, team and how it was built

Started small, grew after funding · sold 11 months after launch

Its founders wrote some of the methods that the industry already used to run models cheaply, such as AWQ for 4-bit weights. They turned that research into a paid serving API, proved the speed on a public benchmark, and partnered with a cloud company that needed exactly that speed. Eleven months after its first public post, the partner agreed to buy it.

AI coding agents can build a working page or deck, but in the founder's words their visual output often looks generic. Skillry sells finished visual styles, one task per Skill, shows real output before the sale, and adds new Skills almost every day under one subscription. When sales began on 28 September 2026, they held at about US$430 a day for 17 days.

It launched in October 2025, when Anthropic's Claude Code had made skills, slash commands and subagents a normal way to steer a coding agent, and when most developers were still writing their own. A founder who presents themself as a CTO with 18 years of experience sold a tested set as a one-time purchase with a money-back promise. Verified revenue reached US$16,040 in March 2026 and US$82,195 in total, but it fell to under US$2,000 a month by September 2026.

It turned a new working habit, running several AI coding agents at the same time, into a native Mac app with voice control and a strong visual style, and it charged once instead of every month. The founder sold it to his own audience through daily live streams, X and a Discord community. Stripe recorded more than three quarters of the revenue in the first seven weeks.

The compression engine already existed as a free, open-source Python tool, but it was hard to install. Garm Lucassen packaged it into a desktop app that installs with a double click, connects the coding agents by itself and removes its changes when it quits. The engine's creator suggested that he build it and keep the Headroom name. Developers who hit the usage limits of their AI plans pay a small monthly price to make those limits last longer.

AI agents that run for hours or days need an address that people can write back to, and a normal personal mailbox needs a browser login and OAuth consent screens that a program cannot click through. Robotomail sells a mailbox that a program can create and read without a person. It started in March 2026 and connects to Claude, Codex, Cursor and other agents through MCP, an API or a command-line program.

A voice agent must answer within a fraction of a second, or the conversation feels broken. The founder writes that the slow step is almost always retrieval: each lookup crosses the network to a cloud database. Moss moves that lookup into the agent's own process.

Three founders who met in an Antler cohort in Berlin launched it in February 2025, in a category that, as The Next Web wrote in May 2026, "barely existed 18 months ago". With self-serve plans and unlimited users it signed 1,300 brands and agencies in about nine months, the company said, and two funding rounds within ten months paid for a large sales and engineering team in Berlin and New York.

It appeared in December 2022 as a free Chrome extension that put ChatGPT inside the Gmail reply box, and the company says it was the first to do so. The founder says they shared it on Reddit and it grew from there. A free version that used the visitor's own ChatGPT account built a large base of installs, and a paid version on the company's own servers followed in 2023.

A weekend experiment that stored text embeddings inside video frames went viral on GitHub in 2025, and the founders say thousands of developers started building on it. They rewrote it as a file format in Rust, kept the core free and open source, and charge for larger memory files and for enterprise deployment.

The founder turned the go-to-market frameworks she uses as an advisor into a product with one job and one price. It is a small, early business: Stripe data shows US$500 of revenue in its first four months and two active subscriptions in November 2026, and the founder has listed it for sale.

Johnny Siu had led tenancy services at Goodlord, a UK rental software company, and saw property teams spend their days on the same messages. Antler's partner wrote in October 2024 that 87% of tasks in the industry are repetitive and low-skill. Tenants already wrote on WhatsApp, so an AI that answers there, inside the operator's own policies, saves staff time without asking the operator to change systems.

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.

The founders are lawyers who built the legal departments of two Berlin startups, and the CEO writes that he knows the frustration with old legal software from that work. LawX replaces the whole office system instead of adding one more AI tool, it charges one price per user for the whole team, assistants included, and every AI suggestion waits for a person to approve it. tech.eu reported in May 2026 that the next step was the broader law firm market.
