Hamster: Product, team and how it was built

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. They 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.

It aimed at regulated enterprises that needed AI agents on their own servers, with audit logs. The company said in 2025 that hundreds of organizations used it. Asana bought it in May 2026. Asana's quarterly report states the price.

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. By then, Anthropic's Claude Code had made skills, slash commands and subagents a normal way to steer a coding agent. 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 into a native Mac app. The habit was running several AI coding agents at the same time. The app had 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. The app 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.

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.

It named a problem that many builders saw in 2025 and 2026: screens written by AI coding tools look alike. It sold the fix inside those tools, as an MCP server for Claude Code, Cursor and other coding agents, first published on 29 March 2026. Stripe revenue in April was 12.2 times March. Since April revenue has fallen, and September was 37.2% below it.

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.

Office managers who move into an unrenovated office often cannot pay an interior design studio, and generic AI image tools invent a different room. DreamOffice keeps the uploaded room and asks for a brief in fixed fields. The founder says on TrustMRR that all sign-ups came from search. The business is very small: Stripe shows US$377 in total, and the founder himself puts the real figure lower, at US$225. In November 2026 he listed it for sale for US$2,000.

Three founders treated each app as an experiment in pricing and paywalls. Lessons from Pixi, the first app, went into Cue. The studio rents the models and does not train them. It spends its effort on design, data and paid user acquisition. Its founders call these the three Ds.

It reached the App Store early, in July 2023, with the simplest form of the idea: press one button, get a transcript and a summary. The founder paid for Meta ads while they still worked for a new kind of app, tested paywalls constantly and moved buyers to annual plans. He works alone with AI coding tools, so in his own 2026 account about US$3 million of about US$7 million a year stays as profit.

The founder took a twenty-year-old product category with no open-source entry and open-sourced all of it. This gave him millions of Docker downloads and 37,000 GitHub stars without a marketing budget. Revenue stayed small for a year. It multiplied when he turned the product toward people who automate their posting with n8n workflows and, from late 2025, with AI agents. Agents need an API-first scheduler and keep paying because they post without human effort.

It entered a crowded category in March 2025 with paid advertising instead of a personal audience. It treated the economics of each ad channel as the product to optimize. Cheaper attribution let it test low-cost traffic. Weekly advances on App Store payouts let it put each week's earnings back into ads within days instead of 45. Adapty, the company whose software runs the app's subscriptions, published the figures under its own name.

Every team that builds with AI models ends up with several provider accounts, keys, invoices and SDKs. One gateway with open code replaces them, and a developer can read the code before sending traffic through the hosted version. In 2026 the founders added DevPass, a flat monthly price for coding agents. Its allowance is up to three times the price in model usage. The verified monthly receipts grew from US$57,994 in January 2026 to US$249,922 in August 2026; TrustMRR does not split them by product.

The plugin lives inside Obsidian's community plugin store. The founder says that the store gave it organic growth with no ads or paid creators. The downloads reached 300,000 by the end of 2024, 1 million by February 2026 and 2 million by October 2026. The code is free, so there was nothing to sell until the company added a managed layer on top. The layer is hosted models, web search and tools that work without any setup. One-time lifetime plans, first Believer and then Supporter, brought large payments in single months. TrustMRR, reading the company's Stripe account, shows US$913,644 of revenue in total. Monthly recurring revenue was US$17,899 from 1,356 subscriptions on 27 October 2026, after a fall of about 51% from the best month, February 2026.

xAI released Grok Bot, a messaging app of AI agents, in beta on 11 August 2026. The two founders published their own open version about two hours later, under the name OpenGrokBot. They pitched it to people who wanted the same idea on Claude or Codex instead of Grok. Payment records show the first payment on 27 September 2026 and US$5,503 in the 30 days to 25 October 2026.
