About

Kat Mayer

I build AI tools people love to use

I've been at Kapwing for 5 years. Started in customer success, moved into PM, and have spent the last 3 years owning AI tooling and monetization. I've launched products that scaled to 100k+ MAU, negotiated vendor contracts, and shipped my own bug fixes when needed.

Starting on the support side gave me something most PMs don't have: I actually talked to users every day before I ever wrote a spec. That still shapes how I work. Outside the job I help manage my partner's music career, make content with him, and take art classes whenever I can.

AI Dubbing

This was a 0-to-1 launch I owned end-to-end, from figuring out if it was worth building to shipping it and growing it. The tool lets creators translate their videos into 40+ languages while keeping their voice intact. It hit 30k MAU after launching in January 2024 and ended up driving 86% of our enterprise contract wins in 2025. I also set up a QA operation with 10 contractors evaluating dub quality across 15 languages.

AI Voice

Launched our text-to-speech tool with AI avatars. 70+ languages, 200 voices, scaled to 128k MAU. I also owned the vendor side of this one and renegotiated our TTS contract, which improved margin by 33%.

AI Clip Generator & Platform Monetization

We had a clip tool that wasn't working. I killed it, built a replacement, and grew workflow users from 5k to 11k. Monthly upgrades went from 14 to 135. On the monetization side, I pitched a unified credit system to replace our messy tool-by-tool pricing. It made the paywall clearer and made it way faster to launch new products.

Customer Success & B2B Pipeline

Before I moved into PM, I was talking to 100+ customers a week. That experience is probably the thing I'm most grateful for. It's hard to build good products without that kind of direct feedback loop. I also built Kapwing's first B2B sales pipeline from scratch, closed contracts with 11 teams, and launched a pro bono program that got the software into the hands of 1,000+ students and teachers.

In addition to digital products, I love building with my hands. In my free time I take art classes and have grown a love for oil painting and ceramics.
