WebbyLab vs Sii Poland: overview

WebbyLab

WebbyLab was founded in 2011 and is based in Kyiv, Ukraine, with a team of 120 or more engineers across hardware, firmware, and software disciplines. The firm delivers device firmware in C and C++ alongside edge computing and cloud dashboard work as one engagement, which cuts down on the number of vendors a client has to coordinate for a full IoT product. Embedded and IoT work sits alongside a broader software portfolio spanning fintech and e-commerce, so firmware is one practice area among several rather than the company's sole focus.

Sii Poland

Sii Poland was founded in 2006 and is headquartered in Warsaw, Poland, reporting more than 7,500 specialists company-wide. Firmware and embedded systems R&D form a dedicated practice within a much larger IT services and engineering business that also covers automotive, telecom, and enterprise software, positioning Sii as a scale option for programs that need large, sustained staffing rather than a boutique specialist team. That scale is the firm's clearest advantage and also its clearest trade-off: a small firmware project competes for attention against far larger enterprise accounts.
