emmtrix's EIC Accelerator Project: Parallel Code Against Revenue

Every car with driver assistance runs on processors with several cores, and code only gets faster on them if someone splits it into pieces that run side by side without corrupting each other. Doing that by hand is slow and error-prone, which is the problem emmtrix Technologies, a 2016 spin-off of the Karlsruhe Institute of Technology (KIT), set out to automate. In the European Commission's list of winners of the 5 June 2019 cut-off of the EIC SME Instrument Phase 2, the Horizon 2020 forerunner of today's EIC Accelerator, EMMTRIX of Karlsruhe appears with one row and no partner companies, for "Software Parallelisation with emmtrix Parallel Studio".

The grant agreement was signed on 5 November 2019. The project ran from 1 December 2019 to 30 November 2022, with an EU contribution of €1,927,178.75 towards a total cost of €2,753,112.50, according to CORDIS. The application promised a faster market entry and, "mainly through license sales, a potential turnover of €8.82 million by 2024". Seven years later the company is active and still sells its tools. Whether its sales came anywhere near that figure cannot be checked: emmtrix has never published revenue.

Where emmtrix Stands in 2026

The company is operating. The register shows no insolvency or liquidation, and its accounts for 2024 were published on 20 November 2025, according to North Data. In September 2025 it joined NeAIxt, a Horizon Europe project on edge AI with 60 partners, in which CORDIS lists an EU contribution of €270,750 for emmtrix, as the company also reports. In April 2026 it published a recruiting post for software jobs in Karlsruhe, and in October 2025 it marked ten years since its EXIST start-up grant from the German economy ministry.

Its address moved in July and August 2024, according to North Data; the company's own page dates the move to Erbprinzenstraße to June 2024. The same street address appears on the CORDIS records of its EU projects.

The Technology: Splitting Code Across Cores, Then Proving It Still Works

Engineers in cars and aircraft often write control software in C or in model-based tools such as Simulink, and the code then has to run on chips like Infineon's AURIX TC4x microcontrollers, which have up to six cores. emmtrix Parallel Studio analyses that code, decides which parts can run at the same time, and rewrites it as parallel C code for the target chip. The CORDIS summary claims this cuts the effort "from several months to a few weeks or days"; the company's 2018 Phase 1 report claimed cost savings of "up to 80%" in tested cases. Neither figure has been confirmed by a customer in public.

What sets emmtrix apart from compilers that parallelise automatically is safety. Code for brakes or flight controls must be qualified under standards such as ISO 26262 and DO-178C, and an automatic tool that rewrites code is hard to qualify. emmtrix's answer is a separate checker that proves, after every run, that the parallel code performs exactly the same calculations as the original and is free of race conditions and deadlocks. Its qualification kit claims use up to ISO 26262 ASIL-D, and the method is covered by European patent EP3944071 on validating parallelised programs, recorded in June 2023 by North Data and listed among three granted European patents on the company's page.

The product line has since broadened beyond parallelisation. The company now lists a Performance Estimator that predicts how long code will take on a chip without running it, a Dependency Analyzer, a Code Vectorizer, an Edge AI Compiler and a C++ to C Compiler, all bundled since November 2023 in a framework called emmtrix Studio, according to its company page and its 2026 recruiting post. Parallel Studio is still on that list, but at embedded world 2024 the company put "our two analysis tools", the Performance Estimator and the Dependency Analyzer, at the heart of its booth, not the parallelisation product.

What the EIC Project Promised, and What CORDIS Shows

The CORDIS report lists five objectives: full compatibility with industry standards, features needed for tool qualification, automated testing of the tools, a business plan matched to the market, and a wider partner network. After the first period, emmtrix reported that C++ support and a functional equivalence checker were ready, built with five newly hired developers, and that an ISO 9001 certification process had passed an internal audit. After the second period it reported a pilot with Bosch on estimating the run time of AUTOSAR software components on Infineon AURIX chips, and said more pilots were planned for the second quarter of 2022.

The report published for the third and final period, which ended on 30 November 2022, contains no new results: it repeats the text of the first two periods. CORDIS lists no deliverables or publications for the project. Whether the further pilots took place, and with whom, is not public, and no ISO 9001 certificate for emmtrix could be found.

1. Full C++ supportDeliveredReported ready by CORDIS; the C++ to C Compiler 2022.10 with C++14 shipped on 24 November 2022.
2. Equivalence checker for tool qualificationPartlySold as a qualification kit and patented; no completed customer qualification is public.
3. AUTOSAR supportDeliveredAUTOSAR development partner since 2021 and an AUTOSAR workflow in its tools.
4. GPU and FPGA supportUnverifiedClaimed in the CORDIS report; no independent evidence found.
5. Industrial pilotsPartlyOne Bosch pilot reported on CORDIS; the pilots planned for 2022 were never reported.
6. €8.82M turnover by 2024Not achievedNo revenue announced; 2023 balance sheet total was €1,861,673.

The technical promises held up better than the commercial one. The features the EU paid for exist in products that are on sale. The €8.82 million revenue target has never been confirmed by the company or by any third party, so it counts here as not achieved. The project closed on schedule after 36 months.

What emmtrix Has Built Since the Award

Since the award, emmtrix's growth shows up in partnerships and research contracts rather than in funding rounds. In 2021 it became a development partner of AUTOSAR, began working with Synopsys and signed value-added resellers in Japan (NeXtream) and China (Beijing Siener Electronics), according to its 2021 review. That year it was also named best start-up at the ELIV automotive electronics congress. Its partner page now lists Infineon as an associated design partner, plus MathWorks, TASKING, AbsInt, DLR and Airbus Defence and Space UK. Its customers are unnamed: the page cites a "German Premium OEM" and a "German OEM".

Public research money has kept flowing. North Data, which mirrors the German federal funding database, lists national grants for an avionics parallelisation project from June 2020 (€531,546), the MANNHEIM-CeCaS car supercomputing project from December 2022 (€401,376) and TwinSpace from May 2023 (€374,118), and Covid-19 state aid of €138,469 in 2021. On the EU side, CORDIS shows €235,000 for emmtrix in StorAIge, an edge AI memory project that ran from July 2021 to October 2024, and the NeAIxt contribution from 2025.

The Money

As a small German GmbH, emmtrix only has to publish a short balance sheet, without revenue or profit. Filed accounts exist for 2019 to 2024, but the figures sit behind paywalls at North Data. The one figure available free comes from Implisense, which gives a balance sheet total of €1,861,673 for 2023 and classifies the company as a small enterprise. That is a modest balance sheet for a company that projected €8.82 million of annual turnover by 2024, but a balance sheet total is not revenue, and the gap cannot be measured from public data.

Staff numbers are also unclear. Startbase gives a range of 11 to 50 employees. The CORDIS report records five developers hired during the first year of the project. No filed headcount is publicly available.

Why Europe Should Care

Car makers are moving to software-defined vehicles, in which a few powerful multicore computers replace dozens of small control units. The Commission's Industrial Action Plan for the automotive sector of 5 March 2025 names chips, software and AI as the core of the connected car and plans an open European software platform for such vehicles, built with shared tools, according to Baker McKenzie's summary. The tools that turn safety-critical code into multicore code are part of that software supply chain. emmtrix's work in MANNHEIM-CeCaS on a central car computer and in two EU edge AI chip projects puts a small Karlsruhe company directly in the field the plan targets.
