KyanSantiago-Calling

I build consumer apps that spread on their own.

Founder of Six String Studio. Co-founder of Raze Labs.

hey, I'm Kyan.

I'm 20, Boston bred, building in San Diego. I make apps for guitar players under my company, Six String Studio, and I co-founded Raze Labs with Ian Carscadden.

This is my guitar. Go ahead, play it.

What I'm good at: Consumer apps people send to their friends, onboarding and paywalls, paid social and UGC, audio and ML products, shipping fast.

how I got here

2023

Computer science at San Diego State. I left to build.

the capo climbs with every year. strum it and hear it get higher.

2024

Machine learning data associate at Amazon.

2025

Built ToneAdapt, because I wanted to sound like the record on the gear I already owned.

Early 2026

Started Raze Labs with Ian. In April, ToneAdapt went live on the App Store: 100,000 people in the first 100 days.

September 2026

ToneID and GuitarMaxx went out. I set up Six String Studio to own all of it.
