01

Invest

Pre-seed to Series A cheques for software companies with real users or a real edge.

02

Build

An experienced product and engineering team alongside yours — not a slide deck of advice.

03

Scale

Infrastructure, security, app-store launches and the operational muscle to grow.

What we back

Software businesses with momentum.

We look for small, sharp teams solving a painful problem for a customer who will pay. Sector-agnostic, product-obsessed.

SaaS

B2B and prosumer platforms with recurring revenue: developer tools, workflow automation, observability, security, vertical software.

Apps

Consumer and business apps for phones, tablets and desktops — native-quality experiences on iOS, Android, Windows, macOS and Linux.

Startups

Founders at the idea-to-traction stage who need more than money: a technical co-pilot to get the first version right, fast.

More than a cheque

We invest like operators and build like a studio.

Most investors can tell you what to build. We can also help you build it. Every Sterling Bay company gets access to our technology practice: architecture, engineering, AI, infrastructure and launch.
