Hi, my name is

Lewis Kori.

Building Products, Systems and Companies That Endure

I’m a software engineer, product builder and business operator. I build scalable digital products and platforms, lead teams through complex technical decisions, and advise founders on product, technology and business strategy.

About me

Entrepreneur, Operator, and Builder of Systems

I’m a software engineer, entrepreneur and writer. I enjoy building things, understanding how they work and exploring the ideas that shape them.

I started my career in software engineering, working on complex systems, particularly in fintech and payments. Over time, my interests grew beyond writing code into product development, infrastructure, business strategy and eventually building companies of my own.

Today, I’m the co-founder of Inflection Studio, where we build digital products, work with businesses on technology and product strategy, and advise founders and investors. I also spend time building and exploring ventures of my own.

My approach to work is shaped by a belief in ownership, good judgement and long-term thinking. I enjoy understanding problems from different perspectives, connecting ideas across disciplines and turning those ideas into something useful. I tend to think in systems, but I like seeing those ideas come to life through products.

Outside of that, I write quite a bit. About software, AI, entrepreneurship, leadership and sometimes life more generally. Writing helps me make sense of what I’m learning, question my assumptions and document how my thinking evolves. I don’t always have the answers, and increasingly, I’ve come to appreciate the value of being curious enough to keep asking questions.

I’m also involved in mentoring emerging engineers through KamiLimu, something that continues to shape how I think about learning, opportunity and the responsibility that comes with experience.

Photography and travel offer a different kind of exploration. They give me a reason to slow down, pay attention and experience places beyond the routines of work. I’ve started documenting some of those experiences here, collecting photographs, videos and stories from places I’ve been and moments I want to remember.
