Mimi Tran Zambetti
Co-founder at Wren
I'm a founder who likes building things that matter and understanding problems deeply. I co-founded Wren, where I still work on climate software, and Topos, an AI platform for renewable-energy developers (acquired by LandGate). I'm comfortable working end-to-end: research, design, engineering, and iterating after ship. Outside of work I'm usually studying a language or in the garden.
Wren
Since 2019 I've been building Wren, helping people in 150+ countries understand their climate impact and fund credible climate solutions. Our community has raised over $24M for our project partners, from mangrove planting in Myanmar to biochar carbon removal in California.
Topos
Topos gave renewable-energy developers AI-powered due diligence, turning messy public data into decisions: mapping competitor leases, pulling permitting rules from local ordinances, reading community sentiment from local news. I designed and built a multi-step agentic pipeline to solve this end to end. Acquired by LandGate, December 2025.
Things I've built on the side
Tuto: After about 140 hours of Vietnamese lessons on italki, I realized I wasn't retaining much from week to week. What started as an app to practice phrases from tutoring quickly grew into an article reader, journaling & corrections app, and lesson generator. I wanted a language learning tool that could teach me what I actually want to say. Try it out on web and let me know what bugs you run into! Or let me know if you want to try the mobile app!
Outside of work
When I'm not building, I'm usually on a run, in an art class, or in the garden tending to cherry tomatoes, picking precious strawberries, and drowning in zucchini. See what I'm reading on Goodreads.
Where should we go next?
