We align on requirements, constraints, and success criteria before any design work begins. No surprises downstream.
Schematics, mechanical concepts, firmware architecture, and system specs, reviewed and approved before anything is built.
Working hardware in your hands, with engineering support through integration, testing, and each revision cycle.
Gerber files, BOM, firmware source, mechanical drawings. Everything your contract manufacturer needs to build at scale.
Electrical, firmware, mechanical, and software in one team. No integration gaps, no finger-pointing between vendors, no translation tax between disciplines.
Our engineering is inside products that consumers and professionals buy today, from high-end audio equipment to avionics hardware to medical wearables.
You work with the engineers, not account managers. Every decision is made by people who understand what's physically on the board.
"Grinalds Solutions delivered top-notch engineering expertise when we needed it most, working quickly and communicating clearly at every stage. They owned the complicated high-speed digital and analog hardware design and were able to integrate with our software, audio, and DSP teams as if they were part of the company. Their prompt, effective problem-solving not only addressed our urgent needs but ultimately ensured our project's success."
