Build with Us

Hardware, engineered to ship.

Kieran has built three hardware companies — using the latest tools to get them built faster, cheaper, and better.

Sol Spektrum

DTC photonic stimulation device · Live

Photonic stimulation that entrains the brain. Engineered from the LED out.

Custom electronics, a mobile app from scratch, firmware modifications all the way down to the LED drivers, and a 500+ part BOM sourced from a supply chain we built from zero. The engineering was not the hardest part. The hardest part was making five hundred parts feel like one smooth, delightful product.

Users report shifts in how they feel — and how they sleep the night after. "Like going back into the womb," someone said. SOL1 is shipping soon.

Scope

Custom firmware, industrial design, supply chain, mobile app development, custom electronics.

The earliest Primer Wand prototype — black rubber bulb and brass fittings on a red metal workbench.
Onshape CAD model of the Primer Wand — purple body, clear chamber, sphere tip.
A polished purple 3D-printed Primer Wand prototype, fully assembled.

The Primer Wand

Patent-pending plumbing applicator · Live

A patent-pending sealed-bottle applicator. On the shelf at U-Plumb-It.

The brief was a real jobsite frustration — plumbers losing time, primer, and rags every time a can tipped over. We took it from prototype to a patent-pending sealed-bottle mechanism, into manufacturing, onto shelves. Engineering, brand, supply chain, and customer acquisition under one roof.

Made by plumbers, on the shelf at U-Plumb-It. Sebastian Merrell, cofounder and master plumber: "I couldn’t have got it done without Kieran."

Scope

Prototyping, business plan writing, vendor sourcing, design for manufacturing, patent draft and filing, customer acquisition.

FridgeSense

Coming soon.

FridgeSense

Commercial refrigerator monitoring · 2026

Commercial fridge monitoring in three minutes. Built for the harshest conditions in the kitchen.

Every day, hundreds of thousands of dollars of food in the U.S. get thrown out because a fridge failed and no one caught it. The existing market is split between old, expensive equipment built on legacy hardware, and consumer-grade gear not made for the back of a commercial kitchen.

FridgeSense is the first easy-to-use commercial fridge sensor — three-minute install, continuous coverage in the harshest conditions a kitchen can throw at it. First batch ships Q4.

Scope

Coming soon.

Got an idea for a hardware company? We can take you there.

Houston-based engineering shop. We design electronics, write firmware, source manufacturing, and stand up the brand around it. One or two calls, then a proposal.
