About Us
We are a high-tech development firm, founded in 2014 as a spin-off from Luleå University of Technology. We have expanded rapidly and grown strong since 2017 and are now a great team of +15 people, with offices in Luleå, Sweden and Palo Alto, CA, US. Together we cover a range of competence areas, enabling us to offer products, systems, and services for some of the latest technologies in the marketplace, including analogue and digital technology, high-speed data-processing and embedded systems.
WE ARE BUILDERS
We build embedded system solutions and offer product, system and service supplies.WE ARE DEVELOPERS
We develop and utilize internal IP´s and platforms and have an in-house prototype lab.WE ARE PROVIDERS
We provide system deliveries to a range of industries, including automotive, mining, manufacturing and home automation.Capabilities
Hardware
Grepit AB works closely with customers to create innovative and advanced embedded solutions that meet their needs in a precise and cost effective manner. Our hardware team develops, assembles, tests, and verifies ideas from start to finish. We have a background of working with several EDA applications, such as Altium Designer, KiCad, and Autodesk Eagle. We use Spice/PCB simulations for high frequency designs, and have experience of working with National Instruments Compactrio Real-time controllers.
Lab
At Grepit we have the capability to assemble high density BGA chips as well as both bonding bare-die integrated circuits and flip-chip assembly, allowing us to produce high density circuits and perform small scale advanced prototype series. We have a wide range of tools for measurement and verification of GigaHertz-range applications, allowing us to design and verify advanced high-speed prototypes as well as letting us perform compliance testing of finalized products.
Signal Processing
Established software platforms such as Matlab/Octave GNU allow us to operate in a fast-iterative cycle of problem assessment, from the analysis of the data to signal processing-based optimization techniques. Through numerical optimization we provide both software improvements of the performance but also insight and directions towards improving the hardware itself.
Software
Most of our embedded software is delivered as a part of a hardware/software solution and either performs data acquisition, analysis or process control. This is usually done in C, C++ or Rust on top of embedded linux for more complex FPGA solutions or RTFM and Rust for smaller microcontrollers.
We also provide software for products that are unrelated to high-speed data processing and analysis such as smart home systems and handheld devices. By using our combined hardware and software capabilities, we can deliver software that is tailored for your embedded systems.

SMART multichannel charge amplifier
A joint project with Orexlore, Luleå University of Technology and Grepit
A multichannel semiconductor detector frontend ASIC is developed in this project, together with IP’s for pulse detection and filtering, data aggregation and high-level control.
This detector frontend ASIC is suitable for measurements in a range of fields, including mineral surveying, industrial processes, radiation safety/detection and automotive sensoring.
