Byte Lab vs Punch Through: overview
Byte Lab
Byte Lab began in Zagreb in 2011 and has grown into a group of roughly 150 people with offices in Croatia and Austria (per company website; independently unverifiable). It is a design partner for both STMicroelectronics and Nordic Semiconductor, and its services include embedded hardware design, firmware and embedded software development, GUI work and low-volume manufacturing. That last point is unusual among firmware vendors: a client can receive working boards in small quantities from the same company that wrote the code. Clutch reviews describe IoT, industrial and consumer device projects.
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.

Byte Lab vs Punch Through: pros and cons
| Byte Lab | |
|---|---|
| + | Low-volume production lets a startup get pilot units without finding a separate manufacturer |
| + | Design partner status with ST and Nordic covers the two MCU families most IoT products use |
| + | Croatian base means EU contracts and rates below Western European design houses |
| + | GUI work on LVGL and TouchGFX suits products with small touch displays |
| - | Low-volume manufacturing stops well short of mass production, so a contract manufacturer is still needed later |
| - | Less public material on regulated medical or automotive safety projects than larger firms |
| Punch Through | |
|---|---|
| + | Firmware and mobile apps from one team removes the usual finger-pointing over BLE connection bugs |
| + | Published technical guides show real depth in BLE throughput, pairing and power optimization |
| + | Experience with connected medical products and their data-integrity requirements |
| - | Narrow focus on Bluetooth LE makes it a weaker fit for cellular, wired or Linux-class products |
| - | Small team, so availability can be limited |
| - | US rates are among the higher ones on this list |
