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 sold one promise that a customer can measure: a first reply to every new lead within 10 seconds, to businesses that already pay for many leads through Meta ads. A demo on the website brought sales calls through organic search before the product was built. Revenue then fell from US$9,000 to US$12,000 a month in late 2025 to under US$2,000 in September 2026, in the same months in which the founder launched other products.

It began in January 2023 as an easy web interface for animation with Stable Diffusion, when the alternative was an open-source library that only programmers could run. Three months later the founder rebuilt it for one group of customers: musicians, who need a video for every song they release and cannot pay a film crew. He calls this the best decision he made.

Companies that let staff use AI need one login, one bill, rules on which model each team may use, and a way to share what works. AICamp sells that layer on top of the model providers, per user, to small and medium-sized companies. The directory Arrfounder listed it at US$25,000 a month in a record created in June 2025, 17 months after the private beta.

Pricing a tender is mostly reading: estimators spend days moving numbers from PDFs and spreadsheets into their own price build-ups before they can think about the price. The product starts from the documents the contractor already has, so a customer needs no connection to other company software. UpNext World reported in March 2026 that paying customers in Ireland gave it €5,000 in monthly recurring revenue.
