What Sigma Connectivity does

Sigma Connectivity is a Sweden-headquartered global design house and engineering services group, founded in 2013 when Sigma Group acquired the connectivity business from Sony Mobile — itself a continuation of Ericsson's mobile phone development in Lund dating to 1986. The company delivers end-to-end connected product development spanning hardware (electronic design, RF and antenna, mechanics, prototype manufacturing), software (embedded, Android/AOSP, cloud and test), and domain-specific specializations including 5G (up to 39 GHz mmWave), audio and DSP, optoelectronics, battery, and AI/ML. Its offering is anchored by one of Europe's most advanced in-house design, test, and verification labs in Lund and structured as four revenue streams: on-site engineering consulting, full product realization, lab services, and specialized expertise engagements.

The business model is professional-services based: customers pay for customized engineering teams (single consultants through full multi-disciplinary project squads) and for use of proprietary lab facilities, either on-site at client locations or off-site at Sigma offices. Pricing is quote-based and project-specific, with only limited public unit pricing (e.g., EMC testing packages at 35,000 SEK per day). The company serves approximately 300+ clients across eight verticals — Consumer Products, Smart Homes/Buildings/Cities, Automotive, Industry 4.0 & Manufacturing, MedTech, CleanTech, Service IoT, and Industrial & Retail Handhelds — with notable enterprise customers including Volvo Cars, Toyota, Spotify, Jabra, HMD Secure, and BARTEC.

Sigma Connectivity operates through 14+ offices across 12+ countries (Sweden, USA, Germany, Denmark, Poland, UK, Romania, UAE), maintains strategic "Core" technology partnerships with Qualcomm, Silicon Labs, Qorvo, Nordic Semiconductor, and Bosch Sensortec, and is privately held within the Sigma Group (owned by Danir / Dan Olofsson family). Headcount has grown from ~180 at founding to 700+ engineers; in May 2026, Bhavin Patel was appointed CEO, succeeding Jesper Larsson, with a stated emphasis on AI and advanced connected solutions. Revenue is not publicly disclosed.
