Scaling BeInSync from working MVP to production SaaS
BeInSync had a promising MVP with a fragile realtime core and a solo founder out of bandwidth. Acting as the technical side of the company, we rebuilt the sync layer, put real infrastructure underneath it, and freed the founder to sell.
The problem
BeInSync keeps teams in sync in real time — which means the realtime layer is the product. The MVP proved demand, but under real load the sync layer dropped updates, conflicts overwrote user data, and everything ran on a single instance with no safety net. The founder was spending most of each week firefighting instead of closing the customers who were asking to pay.
What we did
We took ownership of the technical side end to end. The realtime layer was rebuilt on a proper WebSocket architecture with conflict resolution, so simultaneous edits merge instead of clobbering each other. Underneath it we put scalable infrastructure — connection state in Redis, durable storage in Postgres, multiple instances behind a load balancer.
Then we made shipping safe: CI/CD with automated tests and rollbacks, a staging environment, and monitoring with alerts routed to us, not the founder.
- Rebuilt realtime sync with conflict resolution
- Scalable infrastructure: Redis, Postgres, load-balanced instances
- CI/CD with staging, automated tests, and one-click rollback
- Monitoring and alerting — we carry the pager
- Auth hardening and security pass across the API surface
The outcome
Since the rebuild: zero sync-loss incidents, roughly 10x the concurrent-user headroom, and a founder who got about fifteen hours a week back — now spent on demos and deals. BeInSync ships weekly, and when something needs deep technical judgement, it lands on our desk, not his.
