Sartura

What Sartura does

Sartura d.d. is a privately held Croatian joint-stock company founded in 2013 and headquartered in Zagreb, specializing in embedded Linux development, integration, consulting, and training services. The firm's core technical focus is OpenWrt, Yocto, and adjacent open-source ecosystems, and it both contributes to and maintains several strategic projects: OpenWrt itself, Sysrepo (a YANG-based datastore co-developed with Deutsche Telekom), Rocket CWMP (a TR-069/TR-181 CWMP client for remote CPE management), UCI2 (a modern libuci replacement for OpenWrt configuration management), and contributions to libqmi, CNDP, and the Replica.one build system. Sartura delivers tailor-made applications, open-source components, Web UI/UX solutions, and custom Linux kernel ports across multiple hardware architectures, with C, C++, Go, Python, and Lua as its primary languages.

The company operates a B2B services business model, monetizing through project-based development, integration, consulting, and training engagements with no public pricing or productized SaaS. Go-to-market is direct sales-led, leveraging content marketing (technical blog), conference presence (OpenWrt Summit, IETF Hackathon, Embedded World, DORS/CLUC, Mipro), and active open-source community participation to attract enterprise clients. Sartura serves four primary verticals — service providers/ISPs, telecommunications operators, embedded device manufacturers, and semiconductor manufacturers — with a customer roster that includes Vodafone, Deutsche Telekom, Telus, IEI Integration Corp, SolidRun, Globalscale Technologies, 8devices, and Mozilla. Its market position is anchored by founder and director Luka Perkov's status as one of OpenWrt's original developers, creating a talent and ecosystem moat that few competing embedded Linux services firms can match.

Direct peers

• Codethink: UK-based software engineering firm delivering embedded systems, Linux distribution and tooling work for safety-critical and industrial customers. Comparable services-led model and deep Linux/OpenWrt-adjacent expertise.
• Timesys: US embedded Linux services and tooling provider offering BSP/Yocto engineering and lifecycle support. Overlaps with Sartura on embedded Linux integration, long-term support and developer tooling.
• Pengutronix: German embedded Linux consulting house focused on kernel, bootloader, Yocto and BSP work for industrial and automotive clients. Comparable as a boutique, engineering-first embedded Linux services peer with strong open source engagement.
• Bootlin: French boutique consulting and training firm specializing in embedded Linux, Yocto, Buildroot and the Linux kernel. Highly comparable to Sartura given its similar open source-first services model, focus on upstream contributions, and embedded Linux training offering.
• Konsulko Group: US-based embedded Linux consulting firm founded by long-time Linux kernel developers, offering engineering services, training and upstream contributions. Closely matches Sartura's founder-led, community-rooted boutique services model.

Others

• Lynx Software Technologies: Provider of safety-critical and secure embedded software (LynxOS, MOSA.ic). Tangentially comparable as an embedded software specialist but focused on safety-critical markets rather than the OpenWrt/networking ecosystem Sartura serves.
• SYSGO: European embedded RTOS and hypervisor vendor (PikeOS) targeting safety- and security-critical applications. Related as an embedded software specialist with European roots, but addresses a different segment than Sartura's OpenWrt/Linux networking focus.

Broad incumbents

• Wind River Systems: Large incumbent commercial embedded software vendor (VxWorks, Wind River Linux) with professional services arm. Comparable at the embedded Linux services layer but operates as a much broader platform vendor competing for the same RFPs.
• MontaVista Software: Established commercial embedded Linux distribution and services provider. Comparable embedded Linux services capability but at significantly larger scale and broader portfolio than Sartura.

Emerging players

• Foundries.io: Platform company offering a managed embedded Linux product (FoundriesFactory) with security and OTA focus. Comparable in OpenWrt/Linux adjacent tooling but competes via a SaaS product model versus Sartura's services model.
