Tradespeople already use WhatsApp all day on the job site, and many write quotes by hand or in a spreadsheet. Tutti puts the office work into that chat, so the customer has nothing new to install or learn. It sends messages through Meta's official WhatsApp Business Platform, which lets one founder run the service without a phone app as the main product.

It sold to large companies from the first months, together with a network of human mentors. An investor reported that it made €30,000 a month within a few months of launch.

The managing director of Techstars Torino reported €3.6M in annual recurring revenue in February 2026.

Large companies run many HR systems that do not share data. So a single case, such as a new hire, passes through several of them by hand. Ahron does not replace those systems; it connects to them, measures where cases wait, and places agents there. The founders had sold an earlier HR software company. The product is built on Celonis, a Munich process-mining company. Its partnership, the founder says, brings in requests from around the world.

The founders came from a company that did outsourced purchasing for other firms. So they knew which purchasing tasks were still done by hand in email and spreadsheets. Soource turned those tasks into agent workflows for large companies. One article from the South Summit Madrid 2026 conference reported 800K in annual recurring revenue and 58 enterprise customers. It gave no currency and did not say who gave the figure.

French renovation quotes depend on subsidy and tax rules that change every few months. The small firm that installs the equipment bears the risk of a wrong file. Argile puts those rules and the building calculation methods into the software. So a salesperson can give a detailed quote within an hour of a visit instead of weeks later.

It moved from a debt-collection tool to AI sales conversations on WhatsApp after a customer asked for exactly that part. Diario Financiero reported in December 2024 that the founders had built an internal product, Iris, to manage WhatsApp conversations. A customer asked to use it for sales and re-enrolment campaigns. Camhi said the team saw that this customer cared about Iris and not about collections. Camhi said that a founder's video about automating WhatsApp with ChatGPT went viral, and the team decided to focus fully on conversational sales.

The first customers came from a lifetime-deal sale on AppSumo, at a time when the product had no AI at all. That gave about a thousand users, word of mouth and a Powered by Guidejar link on every free guide. From April 2024 the founder sold subscriptions instead, and added AI writing, voiceover and translation to the paid plans, metered in credits.

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.

Every team that builds an agent must connect it to other software. The hard part is the login, not the API call: running the OAuth flow, storing tokens, refreshing them and scoping permissions for each user. Composio took over that chore for all apps at once. It gave the SDK away as open source. It charges for usage above a large free tier.

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.

The app costs almost nothing to run: the owner reports a profit margin of 99%. The App Store page shows no new version since July 2025. A small, steady flow of downloads, about 2,500 in 28 days in October 2026, keeps about 150 paid subscriptions alive. The owner is an experienced app marketer who already sells more than a dozen other apps from the same developer account.

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. The founder has listed it for sale.

It appeared in January 2023 inside Google Slides, a program where people already work. At that time 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.

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.

It entered a market where people already paid for tools such as Taplio, and did the one core task better: writing the post. The founders' public posts brought the first customers and a lifetime-deal platform, and that deal paid for growth without investors. Subscriptions, partnerships with LinkedIn influencers, affiliates and a move to team plans came after.
