Founder
Zachary Kim
Founder, Arc Systems
I've been a software engineer since 2020, most recently at Stripe. In my engineering career, I've worked across payments, healthcare and cloud security, building systems that thousands of people rely on every day.
I've always loved solving problems and although working for tech companies was great, I wanted to move faster and see the impact of my work directly. Closer to home, both of my parents own small businesses. They're excellent at what they do, but they've never had the time to keep up with the tools that could make their work easier.
I started Arc Systems to make it easy for businesses to focus on what they do best, while keeping up-to-date with the demands of modern-day technology, especially in the age of AI.
I believe that every business should have a fair shot at competing in the market, and Arc Systems lifts businesses up to get that fair shot.

The same work, at a much bigger scale.
The habits from those roles carry straight into Arc Systems: build what's missing, measure it, and cut what isn't earning its keep.

How we work with you
We treat your business like it's ours.
Understand first
Before we recommend anything, we learn how your business really runs: the tools, the hand-offs, and where things slip.
Fix the cause
"Not enough leads" is usually a symptom. We find what's underneath it and fix that.
Build to last
Documented, owned by you, and built on tools you can keep using. No black boxes.
Own the outcome
We measure whether it worked, and we stay until it does.
Who we work with
Good businesses that have outgrown their tools.
Service businesses that are already good at what they do, but lack the technology, systems and operations to scale efficiently. The work is strong. The website, the follow-up and the tools behind them haven't kept up.
