About

Stackmate

Features
Read full description

Stackmate is where founders find the co-founder who completes the stack. Choosing a co-founder is one of the highest-stakes decisions you'll ever make — yet most people start that search with vague profiles, cold outreach, and gut feeling. Stackmate was built for this specific problem: structured profiles, real signal, and accountability before you ever get on a call. HOW IT WORKS 1. Build a structured profile Pick your role — Founder or Candidate. Describe your project, skills, commitment level, and exactly what you're looking for. Verify your identity and optionally connect GitHub and LinkedIn to surface real, hard-to-fake signal. 2. Discover scored matches Every match comes with a compatibility score across four dimensions — skill fit, commitment level, timezone overlap, and startup stage. Browse clean, detailed profile cards with everything you need up front. No endless scrolling, no guesswork. 3. Send intent, not noise Reaching out requires a short, structured intent message — so every connection request is intentional and gets a real reply. No cold spam. 4. Meet, review, and decide Schedule intro calls without leaving the app. After each meeting, both sides submit a blind, structured review — revealed only once both are in. Honest feedback, no manufactured impressions. WHY STACKMATE • Compatibility scoring — a weighted match score with the full breakdown visible, not just a headline number. • Verified profiles — identity verification plus GitHub and LinkedIn signal that's hard to game. • Blind mutual reviews — structured post-meeting feedback that stays hidden until both sides submit. • Built-in scheduling — from match to confirmed call in a couple of taps. • Privacy-first — your face verification runs on-device; we only keep the result. WHO IT'S FOR • Founders with a project looking for a technical or business co-founder. • Talented builders looking for the right project and team to join. Stackmate is free to join, with optional Plus and Pro plans for more daily swipes, open requests, and undo. Find your co-founder — built on verified profiles, structured discovery, and mutual accountability.
