SQUARE ONE FOUNDRY
[ PRODUCT DEVELOPMENT / ATLANTA GA ]

The engineering team your startup needs before it can hire one.

Hardware, instruments, and the software around them — taken from a hypothesis to a unit a customer can hold. Biotech, electronics, physical products, software and AI.

[ WHAT WE DO ]

We close the gap between a promising idea and a working, testable product.

Most early ventures hit the same wall: the concept is funded, the roadmap exists, and there is no engineering organization to execute it — hiring one costs a year and a round. We are that capacity, available immediately and without the headcount. Our strength is the work that refuses to sit inside one discipline: an instrument where the electronics, the microfluidics, the firmware and the assay all have to work at the same time, and no single specialist can be held responsible for whether it does. That is the work most teams cannot staff for, and it is the work we take on.

[ SELECTED WORK ]

What we’ve built, and what it took.

[ CAPABILITIES ]

Five disciplines, one team.

[ TWO WAYS TO WORK WITH US ]

Take a milestone off the roadmap, or take the roadmap.

MODEL 01
Fractional engineering team
We embed alongside the founders and take ownership of technical development end to end — architecture, build, vendors, and the decisions in between.
BEST WHEN
You have funding and a roadmap but no engineering org yet, and hiring one would cost you a year.
MODEL 02
Milestone-based project
One scoped deliverable with a defined end: a feasibility answer, a working prototype, a system integrated, an MVP shipped.
BEST WHEN
One technical unknown is blocking your raise, your pilot, or your next board meeting.

Tell us the milestone. We'll tell you what the next 90 days looks like.

One engineer reads every message — usually a reply inside two business days, with a first read on whether we're the right team for it.
