Now building at Melotech

AI product engineer and hit songwriter

I build AI products at startups that take off, and I write songs for some of the biggest acts in Asia. I'm a co-writer on a #1 album in Japan, a founding engineer and a startup founder.

Two careers. One brain.

Portrait of Jacob Critch
Jacob Critch, St. John's, Newfoundland

I ship product by day and write hits by night. Sometimes the other way around.

I'm a software engineer from St. John's, Newfoundland, with a Computer Science degree from Memorial University. I like being early: I was a founding engineer and first hire, a startup co-founder and CEO, one of the first 10 engineers at a legal-AI company now valued at $350M, and an early developer at a startup acquired within two years of founding. I'm currently building at Melotech, which works at the intersection of AI, media and entertainment.

In music, I'm a topliner, producer and vocalist signed with Seoul's Melogram, and I co-founded the production company Gilkicker Music. My songs have landed with &TEAM, THE BOYZ, ALL(H)OURS, SUPERKIND, Anson Lo and Chris Chiu across K-pop, J-pop and C-pop, and my voice is on WARFRAME's in-game boy band On-lyne. I also produce sync albums for libraries like APM, with TV placements on shows including Project Runway and MasterChef.

“I love making music . . . but I wouldn't be where I am in startups right now if I wasn't passionate about it.”

What I do

    I take AI products from zero to one and keep them shipping. Full-stack web and mobile, built fast and built to last.

    • Zero-to-one builds
    • Full-stack web & mobile

  • Systems architecture & LLM orchestration

    I design systems that scale, from multi-step LLM pipelines and agents with tool calling to the evals and production infrastructure that keep them reliable.

    • Scalable systems
    • LLM pipelines & agents
    • Tool calling
    • Evals
    • Production AI infra

  • Growth & product analytics

    I instrument products so the numbers drive decisions: activation, retention, funnels and experiments that show what to build next.

    • Activation & retention

    • Instrumentation

  • Music & audio tech

    I build for creators because I am one: real-time collaboration and audio tooling for people who make music.
