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, and an investor reported that it made €30,000 a month within a few months of launch. The founders then turned the mentoring business into a platform built on skills data, raised a €5.8M Series A in 2025, and 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, and the product is built on Celonis, a Munich process-mining company whose 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, without a currency and without saying who gave the figure.

French renovation quotes depend on subsidy and tax rules that change every few months, and 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.

Food distributors still take many orders by email, text message and phone and type them into old ERP systems by hand. The two founders worked inside a Boston seafood distributor for months to map that work before they built the product. Then they sold it themselves to large distributors: an a16z speedrun newsletter of January 2026 says one enterprise deal with a publicly traded distributor took their booked revenue past US$500,000.

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.

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 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.

It went where the users already were: an app in ChatGPT's app store, a plugin in Claude's directory and in Claude Code, and setups for Cursor and Codex, 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.

One founder had worked as a corporate lawyer and the team sold directly to law firms and banks that it already knew. The product was built on Indian court material, which global tools cover less well. Customers made it part of daily work: when the platform went down for maintenance, users called and messaged the team to ask when it would return.

Bookkeepers still receive many bank statements as PDF files and type the transactions into accounting software by hand. The founder is a QuickBooks consultant who had this problem himself.

The founders came from digital marketing agencies, and their first customers were people from the CEO's former agency team, who now work in the marketing departments of large Turkish companies. In 2026 the company rebuilt its dashboard product around the Model Context Protocol, so that general AI assistants can work on live ad data, and opened it to everyone with a free plan.

The founder is a home inspector who, the company says, paid for six separate tools that did not share data. He built one app for the whole job and lists a lower price than the market leader, Spectora. The AI tools write the paragraphs that inspectors otherwise type again for every house.
