Replicas: 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.

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.

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 went where the users already were. It became an app in ChatGPT's app store and a plugin in Claude's directory and in Claude Code, with setups for Cursor and Codex. It did this in the months when these directories were new. It charges per tool call instead of a share of ad spend, so a small advertiser starts at US$49 a month. And it applied to the platforms' own API programs. The company says Google approved it in June 2026 and Amazon admitted it to its partner network.

The first apps that combined OpenAI's Whisper and ChatGPT for voice notes appeared in 2023, and the founder found them "not implemented well enough". His team built a simpler one, and collected early users and feature requests through lifetime deals on AppSumo in 2024. In 2025 it grew with advertising and paywall tests measured in Adapty's subscription data.

A carousel needs both writing and design. Draft AI asks for a minute of speech instead and returns finished slides, plus scripts, threads and hooks from the same recording. It charges before the first result, so everyone who uses it has subscribed or started the trial of a paid plan.

People who plan a haircut or a new colour cannot see the result before the salon has done it. The app shows it on the user's own photo in seconds. It uses Google's Gemini model to analyse the hair and fal.ai to generate the image, as its privacy policy states. Revenue was close to zero until March 2026. In April 2026 the seller shipped a redesigned onboarding, a new paywall, a coin system and translations. From then revenue rose every month, to US$17,882 in October 2026 up to 26 October, as TrustMRR reads it from the billing account.

It turns a label that most shoppers cannot read into one personal number. The diets are ones that a general calorie app does not cover: low FODMAP, seed-oil-free, gluten-free, vegan. The store page says that analysis needs a subscription, so every active user pays. Verified revenue reached US$23,122 in its best month, February 2026, and US$178,939 in total, read from the app's billing account.
