Founding Engineer

Teracy is a presence app for remote workers and people who live apart — designed to help you feel close, even when far away. We’re rethinking what it means to live and work together online with depth, presence, and care.

About Teracy

We’re building a product that helps people truly share time and life together online, not just collaborate. No more cold tools for task management. We believe in designing software with soul, tools that enrich real human connection.

• Launched in Japan, used by startups, public companies, students, and communities (no ads or press)

• 1-week retention 80%, 30-day retention 72%

• Goal: 1M users by end of 2025 — 20K+ on the waitlist already

• Bootstrapped ($1.3M) + Pre-seed funded (~$1.7M raised)

• Preparing for global launch, starting with the US

What We’re Building

A multi-platform presence app for teams, communities, and the people who matter most

• Brand and UX relaunch coming in Summer 2025
