Soource: Revenue, team and how it was built

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.

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.

The founders say that planners in waste depots drag jobs onto trucks by hand every morning, that the plan is wrong within hours, and that companies cannot hire planners fast enough. They had sold an ERP to waste operators since 2022 and learned that large operators would not replace their ERP, so the new product sits on top of the ERP instead of replacing it. In the April 2026 launch post the founders said that annual recurring revenue was US$496K.

The founder took a twenty-year-old product category with no open-source entry and open-sourced all of it, which 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, which need an API-first scheduler and keep paying because they post without human effort.

The founder had an audience before the product existed: a daily YouTube show about SEO since 2023 and an X account that has 62,000 followers today, so the first customers cost nothing. A developer co-founder built the software with AI coding tools. The product started as one plain rank tracker at US$19 a month, grew into a bundle at US$57 to US$2,997 a month, and by July 2025 the first payment of a new customer from a paid ad covered the cost of that ad.

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.

For its first 20 months the product brought in about US$3,500 a month. Then three things came together: phone apps with weekly plans from August 2025, web plans with unlimited use at US$4 a month billed yearly, and a new group of customers, people who make songs with AI generators such as Suno and need the last step done for them. Monthly revenue rose 7.2 times between January and July 2026. No source states which of the changes caused the rise.
