From a blank page to a product used by thousands.
I built production AI agents that research, plan, write, and edit. Then I used real-world feedback to improve output quality, latency, and model cost.

What changes when AI leaves the demo and enters someone's working day? I share what I'm learning about agents, products, and building a business.

Read my posts on LinkedIn A bit about me
An engineer with
a founder's lens.
Based in Toronto, CanadaI'm Ben Liu. My background brings together enterprise data science and full-stack agent engineering. As a co-founder, I've taken a product from the first idea to real users and the messy lessons that come with them.
I care about the whole journey: understanding the problem, building the system, and making it work for the person on the other side of the screen.
Building your engineering team?
I bring hands-on AI engineering, product ownership, and a customer-first approach to AI engineer and forward deployed engineer roles.
