EchoSim is a simulation-first AI dating app where each user's AI twin (an 'Echo') goes on simulated dates to test compatibility before any real conversation begins. Founded in 2026, Echo Sim exists to fix a structural problem: most dating apps make money from attention, so they are built to keep people swiping and texting rather than to get them off the app. Burnout, ghosting, and curated-profile letdowns all follow from that incentive. Our approach moves the draining early-vetting work from people onto their Echoes -- digital personas modeled on a user's attachment and communication styles (we use frameworks like attachment theory and MBTI as descriptive lenses, not clinical or predictive claims). Two Echoes rehearse a relationship privately, and the result is a readable compatibility report -- including what we call a Warmth Curve -- rather than another inbox to manage. We are deliberate about doing this responsibly: we research with synthetic data, default to privacy, and measure success by people leaving the app for a real-life meeting -- not by time spent on it.
