PLUM STREETSTUDIO

Purpose-built software for the industries that power everything

We build software products for established industries long overlooked by modern technology—powered by AI-native development from the ground up.

What We Believe

The energy industry runs on spreadsheets built in 2005. Accounting firms use practice management tools designed before the smartphone. Financial services teams patch together workflows that should be seamless.

These aren't startups waiting for product-market fit. They're massive, established industries generating billions—stuck with software that wasn't built for how they work today.

We build what should already exist. Purpose-built. AI-native. Designed with deep respect for how these professionals actually do their work.

What We're Building

We target industries like energy, finance, accounting, and security—building vertical software with deep domain understanding. Here's the roadmap.

Who We Are

A team of senior technology leaders with decades of combined experience across engineering, cybersecurity, and product management—building software for the industries we know best.

We're based in Colorado. Intentionally small. We believe the best software comes from teams that care deeply about the people who'll use it—not from scaling headcount.

Intentional

We build with purpose, not just velocity.

Domain-deep

We know the industries we serve.

Quality over quantity

Fewer products, built right.

Bootstrapped

No VC. Consulting funds conviction.
