I spent the last few weeks building something I actually needed to exist: a layer that stops SaaS leads from dying between a landing page form and a sales rep's inbox.

Meet LeadSync.

What it does: → Normalizes and dedupes every incoming lead before it ever touches your CRM → Scores each lead with a deterministic engine (fully transparent, no black box) and tags it HOT / WARM / COLD → Routes leads to the right CRM Salesforce and HubSpot based on rules you define, not a fixed pipe → Logs every sync attempt, so a failed handoff never fails silently

I built the whole thing solo: FastAPI + MongoDB backend, an abstract multi-CRM connector architecture, retry/backoff logic, the full pipeline. Every decision , bugs included , gets documented as I go in my "Build Log" series here on LinkedIn.

If you're an early-stage SaaS founder and leads are quietly slipping through the cracks between your forms and your CRM, this is the exact problem I spend my nights solving , either with LeadSync directly, or by building the equivalent inside your own stack.

I'm taking on a few new clients this month. If that's you, drop a comment or send a DM , happy to walk through what I've built and how it maps to your setup.
