Punch Through vs Embien Technologies: overview
Punch Through
Few firms go as deep on Bluetooth LE as Punch Through. The Minnesota company was founded in 2009 by Colin Karpfinger and employs somewhere between 11 and 50 people according to directory listings. It builds connected products where the radio link is the hard part: device firmware on Nordic, Silicon Labs and TI chips, plus the iOS and Android apps that pair with them. Its public guides on BLE throughput, pairing and power use are widely read by embedded engineers. A large share of its client work is medical and consumer health devices.
Embien Technologies
Embien Technologies has run an embedded product engineering business since 2010 from Madurai, India, with additional presence in Chennai, Bengaluru, Palatine, Illinois and Germany. It is a Renesas design partner and sells its own RAPIDSEA protocol stack libraries alongside services. Engagements cover automotive ECUs and instrument clusters, medical devices, industrial controllers and semiconductor reference designs, with team estimates of 60 to 200. Indian rates make it a cost-effective choice for MCU firmware and BSP work.
