H2LooP raised $2 million in a seed funding round.
The round was led by Speciale Invest and 3one4 Capital.
The company is building an AI-native platform for system software development.
This platform helps engineers create and debug software for hardware and embedded systems.
H2LooP uses specialised small language models for firmware and driver code.
The startup plans to use the capital to strengthen its core AI platform.
It aims to drive large-scale enterprise deployments across multiple industries.
H2LooP is currently working with semiconductor companies and defence organisations.

The platform addresses the gap between rapid chip advancements and slower software progress.
It offers domain-specific AI models tailored for C/C++ embedded code.
The startup has been selected for the Infineon Global Startup Program.
It focuses on IP privacy by running models in secure air-gapped environments.

H2LooP's tools make it easier and faster to write system software for hardware.
The AI platform reads existing code and creates documentation for engineers working on embedded software.
It builds specialised small language models (SLMs) for firmware and drivers.
These domain-specific AI models are designed specifically for C/C++ embedded code.
H2LooP offers hardware-aware debugging tools that analyse debug and crash logs.
It can convert PDFs into training data for its AI models.
The models run in secure or air-gapped environments to ensure IP privacy.
This security feature is critical for defence and semiconductor clients.
The startup is also creating a data platform for hardware engineering alongside its coding models.
It targets physical systems and complex hardware architectures.

H2LooP plans to expand into data centres, UAVs, robotics, semiconductors, telecom, and defence.
The company will focus on large-scale enterprise deployments of its AI platform.
It intends to strengthen its core AI capabilities with the new funds.
