Hacod

Hacod is a Poland-based IoT development firm founded on 13+ years of embedded systems expertise. The company builds end-to-end hardware, firmware, and cloud solutions for connected devices, focusing particularly on low-power wireless protocols. Leadership includes Mieszko Mieruński (CEO and Lead Engineer, specialist in low-power firmware and industrial-grade cloud), Julia Tsesar (CMO, UX/UI lead for telemetry dashboards), and Jakub Zimnol (Head of Education, managing knowledge transfer). The team is small and specialized; no total headcount is public.

Services and capabilities

Hacod works across four linked pillars: hardware engineering, embedded firmware, cloud infrastructure, and user applications.

On the hardware side, they handle PCB layout and schematic design, power management optimization, antenna tuning, and design-for-manufacturing (DFM). A typical project: a cellular low-power asset tracker for vehicles with 3-year battery life. They emphasize power efficiency and manufacturability from the start.

For embedded software, they develop firmware in C/C++/Rust, build device drivers and middleware, and integrate real-time operating systems like FreeRTOS, Zephyr RTOS, and Linux kernel builds. They work with Nordic Semiconductor and other chipset partners to optimize boot times and power integrity. Zephyr RTOS appears repeatedly in client testimonials as a core competency.

Cloud and connectivity span AWS IoT Core, Azure IoT Hub integration, and wireless protocols including Bluetooth Low Energy, Wi-Fi 6, LoRaWAN, and LTE-M/NB-IoT. They also handle CoAP protocol implementation and secure boot.

Their process is structured around four phases: discovery (feasibility studies, technical specs, BOM estimates, project roadmaps), prototyping, development, and scaling. Discovery outputs include a Technical Specification Document and component selection guidance before any code is written.

Notable work

Clients named in testimonials include Template Systems (Damien Declercq), FarmSense Inc. (Shailendra Singh), Synergy Partners (Artur Wróbel), VUMO (Adam Paleczny), and ETC Connect (Natalie Slaba). FarmSense reported that Hacod "accelerated our device development. Thanks to our collaboration, we were able to achieve results twice as fast as anticipated." Template Systems founder praised Mieruński's Zephyr expertise and flexibility scaling support. Synergy Partners CEO highlighted responsiveness to customer requirements. An ETC Connect software engineer noted that a two-day Hacod training in Zephyr on the nRF52840 was well-adapted to both MCU newcomers and experienced embedded developers.

How they work

Engagement begins with a no-obligation consultation where technical requirements are discussed. Projects range from $2,000 to $200,000+. The discovery phase focuses on ROI validation and business goal alignment, not just technical specs. Development involves hardware-software coordination, PCB design collaboration, and integration testing. They offer training services to help clients manage their own IoT ecosystems post-launch. Ongoing support includes device updates, security patches, and lifecycle management.

Team and credentials

Three named principals: Mieszko Mieruński (CEO, 13+ years embedded experience, low-power and cloud), Julia Tsesar (CMO, high-density telemetry dashboard design), Jakub Zimnol (education/training lead). The firm lists partnerships with Nordic Semiconductor and references FCC and CE certification capabilities. Clients mention deep Zephyr RTOS expertise as a key strength. No certifications like ISO 27001 or SOC 2 are mentioned in the source material.
