Product analytics counted 2,041 registered accounts in the first month. Primary action: [Talk to us](https://flagridge.com/enterprise#contact) ## Challenge Founders whose audience grows inside someone else's social network know this position. The luxury-watch community lived in a Facebook group, and the group had stopped fitting how watch traders work. Threads that once structured discussion were gone. Members had to split into many similar groups. Facebook offered no watch-specific tools, such as auctions tailored to how watch traders trade. The founders fixed four requirements from the start: a familiar and fast interface for a smooth move from Facebook, real-time chat, roles and moderation, and no custody of funds. ## Solution Two product decisions shaped the platform, and each follows from this client's situation. ![Architecture diagram. Web, iOS, and Android clients use the WatchLink platform. Inside the platform sit a web app and real-time chat, and the platform holds no funds. Deals between members and their funds and payments sit outside the platform.](https://flagridge.com/_astro/02-architecture.BeNjYYJE.svg) - **Money outside the platform:** Members trade high-value watches peer to peer, and holding their money would have added compliance risk to the platform. Deals are arranged and settled between members, outside the platform, to keep that risk off it. - **Facebook habits kept:** Members had to be willing to leave the group, so the product kept their habits. The feed follows a familiar Facebook-style layout, sale posts start from listing presets, and a member can message the poster directly from a post. ## Method A ten-person team worked with AI agents and kept the build on the record. It followed a practice that now carries the name Praxis and had no name then. The team closed each stage with an artifact and started the next stage from it: - Functional requirements, ready at the end of a one-month inception. - Wireframes of the whole app, ready at the same point. - Architecture notes. - About twenty recorded demos, which documented the decisions taken along the way. Hand-offs went through this record instead of through memory. The case describes the practice as this team ran it, not today's Praxis Runtime or role packages. ![Sequence of four artifacts, left to right: functional requirements, wireframes of the whole app, architecture notes, and about twenty recorded demos.

The same review says of the build: > Transparency was clear throughout the build so we were never disappointed by any of this. > > Executive, WatchLink — verified review on Clutch, July 2026 ## Evidence In the first month after the move, product analytics counted 2,041 unique registered accounts on WatchLink, excluding test and internal accounts, against a source Facebook group of 4,000+ members. ![Flow diagram, left to right.

On choosing the team, the client's review says: > We interviewed around a dozen firms prior to making our decision with them and we would 100% do it again. > > Executive, WatchLink — verified review on Clutch, July 2026 ## Result The build took about five months from the start of the work to the MVP. The client's review states that the MVP took longer than originally planned and attributes this to scope growth and some unforeseen problems; it does not give the size of the delay. The public release came almost eight months after the start of the work. The scope grew during the build, and the client chose to go live only together with the iOS app, which came later than planned. The registrations came mainly from the source group, so a start-up or a small business without a ready audience cannot reproduce this result directly. WatchLink is live, and the MVP is delivered for the web, iOS, and Android. ## Your own platform If your community or product lives on someone else's platform and you need one of your own, [start a conversation](https://flagridge.com/enterprise#contact).
