SendStackr is an enterprise-grade AI automation engine that kills manual data entry. Unlike legacy tools that timeout on heavy tasks, we built a zero-bloat Rust backend on a 2-node Kubernetes cluster with custom SMTP/IMAP servers. Using Graph RAG, SendStackr acts as a smart bridge—instantly extracting exact variables from unstructured PDFs, raw HTML emails, and webhooks into perfectly mapped JSON payloads. Route your data directly to any CRM or database with zero latency.

Hey folks! I just launched the beta of my solo project, SendStackr.

I noticed a huge bottleneck for B2B agencies and real estate firms: they receive highly valuable leads and data via messy PDF invoices or unstructured emails, and end up either typing it into Airtable/CRMs manually or using fragile automation tools that time out on heavy tasks.

I decided to build a "smart bridge" to solve this. SendStackr uses Graph RAG to instantly read the context of an email or PDF, extract the exact variables you need, and route it as a clean JSON payload. To ensure it never hits a timeout ceiling, I bypassed the usual API bloat and built the core engine entirely in Rust with custom SMTP servers.

I'm currently looking for early feedback on the routing experience and the UI.
