Lobaro GmbH vs Sigma Software Group: overview

Lobaro GmbH

Lobaro GmbH was founded in Hamburg in 2012 by Tobias Rohde and has grown to around 15 people, a design partner of Nordic Semiconductor and a member of the LoRa Alliance. The company's stated work covers IoT sensors, gateways, and the firmware, backend, and platform software that runs them, with specific protocol experience in LoRa, LoRaWAN, Sigfox, LTE, and wireless M-Bus for industrial metering and monitoring applications. That protocol depth in low-power wide-area networking is a narrower but deeper specialty than the general IoT connectivity claims many larger firms make.

Sigma Software Group

Sigma Software Group was founded in Kharkiv, Ukraine in 2002 by five friends and now employs more than 1,100 people across Ukraine, Sweden, Poland, and the United States. In 2006 the Swedish IT conglomerate Sigma Group acquired a 60% stake in the company, an ownership structure that has held since; the remaining 40% stays with the original Ukrainian founders. Its embedded and IoT services cover application development, firmware, middleware, device drivers, and human-machine interfaces, delivered as one practice within a much larger portfolio spanning gaming, aviation, and telecom software.

Lobaro GmbH vs Sigma Software Group: pros and cons

Lobaro GmbH
+ LoRa Alliance membership and Nordic Semiconductor design partner status verify its low-power wide-area networking credentials
+ Protocol depth spans LoRa, LoRaWAN, Sigfox, LTE, and wireless M-Bus, a specific set most generalist firmware vendors don't cover together
+ 13 years of operating history with a consistent focus on industrial IoT sensor and gateway firmware
+ Received public innovation funding through IFB Hamburg's InnoRampUp programme, an independently verifiable signal of institutional confidence
- A team of around 15 people is small relative to industrial IoT programs requiring firmware across many product lines at once
- LPWAN protocol focus is a narrower fit for firmware projects centered on Wi-Fi, Bluetooth, or cellular broadband instead
- No published pricing or minimum engagement figure
Sigma Software Group
+ 1,100-plus employees across Ukraine, Sweden, Poland, and the US give substantial delivery capacity and timezone coverage
+ 60% Swedish ownership since 2006 brings the governance and stability of an established Scandinavian IT conglomerate
+ 23 years of operating history under continuous leadership from its original founding team
+ Multi-industry portfolio spanning aviation, gaming, and telecom means firmware engineers work alongside teams solving comparable real-time and reliability problems in other domains
- Firmware and embedded work is one practice within a much broader multi-industry engineering group, not the company's sole focus
- 60% ownership by Sweden's Sigma Group means the company is not independently controlled by its original Ukrainian founders
- No published pricing or minimum engagement figure
