What Sigma Connectivity Engineering does

Sigma Connectivity Engineering, legally Sigma Connectivity Group AB, is a Swedish privately held global design house and engineering services group founded in 2013 when it was acquired from Sony Mobile and subsequently grew from 180 engineers to over 700 active engineers operating from 13 sites in 12 countries. The firm is a subsidiary within the Sigma family (owned by Danir, held by the Dan Olofsson family) and offers end-to-end connected device and IoT product development — from concept and industrial design through electronic, mechanical, embedded software, Android, and cloud development to industrialization — serving global tech companies across Consumer Products, Smart Homes/Buildings/Cities, Automotive, Industry 4.0, MedTech (via ISO 13485:2016-certified Sigma Connectivity MedTech AB), CleanTech (via Sigma Lundinova), Service IoT, and Industrial & Retail Handhelds. Marquee engagements include the Hovding 4 cyclist airbag for iSi Automotive, the BARTEC EX 5G smartphone, Spotify's Car Thing, Toyota IoT integrations, and the Owl + Lark Lamp Zero circadian lamp.

The company operates one of Europe's most advanced design, test, and verification lab footprints, including seven EMC chambers, anechoic RF/antenna chambers, audio/acoustic labs (two full anechoic rooms down to 200Hz, HEAD Acoustics and Audio Precision equipment), optoelectronics labs, and a prototype facility with SMT line, CNC, 3D printing, and 2D/3D X-ray — capabilities inherited from the Sony Ericsson/Sony Mobile lineage. The technology stack spans 2G-to-5G cellular (Cat M1, NB-IoT, mm-wave up to 39GHz), Wi-Fi, Bluetooth, GNSS, NFC, UWB, and Matter, with growing emphasis on Edge AI, computer vision, and audio DSP. Strategic platform partners include Qualcomm Technologies (IoT Accelerator Partner, QCM6490 reference design co-development), Ericsson (Ardesco IoT reference design), Nordic Semiconductor, and Scanfil for manufacturing.

Sigma Connectivity monetizes through professional services engagements with fully customizable delivery models — on-site consultancy, full project-based development, and lab-as-a-service — priced via project quotes, with a publicly disclosed EMC pre-compliance package at SEK 35,000 per full day. The firm sells directly to enterprise and select startup customers, supported by case studies, industry events, partner marketing, and educational outreach. Revenue is undisclosed, but the firm reported 12% growth in 2024 amid consultancy market volatility and operates with 300+ clients and 3,000+ successful projects delivered historically.
