Full stack dev seeking to join as co-founder

Civil engineer here (PE, 15 years in California). I've been on both sides of land development design space— designer and reviewer — and I've watched the AEC software space stagnate for my whole career.

Looking for a technical partner who wants to take on Autodesk and Bluebeam in a space they've been milking for decades. The incumbents can't fix what's broken without cannibalizing in which they charge a fortune.

Think of it as Figma for AEC. Happy to share more.

This is a solid post, especially the “sell vs build” clarity.

One thing I’ve been noticing working on AI-heavy systems is that once you start wiring outputs into real workflows, you hit a different class of problems than just building features, more around reliability and edge-case behavior over time.

Curious if you’re leaning toward products where that kind of systems thinking matters, or more straightforward SaaS?

Useful perspective — the community benefits a lot from founders sharing both wins and setbacks. How long did it take to get to this point?

Hey— saw your post about looking to join a startup and wanted to reach out directly.

I'm building CareAuth — an AI that eliminates prior authorization denials for clinics. Prior auth is the process where doctors need insurance approval before a patient can receive care. Every insurer has different requirements. One wrong field means automatic denial and a 3-week restart. This costs US clinics $13B+ annually.

We validate every submission against that specific payer's exact requirements before it goes out. The model learns from every approval and denial across our network — one clinic's failure becomes every clinic's protection.

2026 CMS regulations are forcing the entire industry onto digital infrastructure. That window is open right now.

What we need from a full-stack engineer:
— Build the clinic-facing dashboard and intake form
— Own one EHR integration (athenahealth or eClinicalWorks)
— Build the outcome capture mechanism that feeds our AI

Seed stage. Equity-heavy. 10-week MVP sprint. Real problem with a hard regulatory deadline creating urgency no competitor can manufacture.

If any of this sounds interesting — even slightly — I'd love a 15-minute call this week. No pitch, just a conversation.

What does your availability look like?

Nice

Quick question — as you’re building, have you ever had parts of a system behave differently over time even when nothing obvious changed?

I’ve been seeing that a lot with AI-integrated workflows.

Been working on a small runtime layer that stabilizes that kind of drift underneath systems — not replacing anything, just keeping behavior consistent.

Curious if you’ve run into that yet or not.

Hey Rafal,
Built a platform called Startr (getstartrapp) for exactly this kind of search. Invite only, proof of work required to get in , so no Notion doc people, only founders who've actually built or sold something.
Think it could be a good fit for what you're looking for.

Rust/WASM expertise combined with a shipping-first mindset is a rare find, Rafal. Your "you sell, I build" approach is the ultimate partnership model for founders who have the distribution but lack the technical depth to scale beyond a simple prototype.
I’m currently running a project (Tokyo Lore) that highlights high-level technical builders and high-potential business logic. Since you're looking for partners with real customer traction, testing your "full-stack dev" pitch in a competitive environment could be a perfect way to attract founders who are already moving fast and need a senior partner to keep up.
