Reson8

Customizable domain-specific ASR for European languages

Overview

Reson8 builds an automatic speech recognition platform tailored for European languages and domain-specific terminology in regulated industries like healthcare, legal, and finance. It uses a base speech model with small pluggable adapters that customize performance for a given context in seconds, using only text for configuration, and can handle 20+ languages with contexts up to about one million tokens. All processing runs on Europe-based GPU hardware with a zero audio retention policy, ensuring data sovereignty and GDPR compliance. The company aims to provide accurate, privacy-friendly, domain-aware transcription and scale coverage across Europe while meeting strict governance requirements.

Simplify's Take

What believers are saying

  • Balderton led Reson8's €5 million pre-seed round on 19 March 2026.
  • Reson8 hired for AI Researcher and Founding Account Executive roles in 2026.
  • Solvimon named Reson8 its first AI model and lab customer in April 2026.

What critics are saying

  • Google, OpenAI, and Deepgram undercut pricing with broader ASR distribution by 2027.
  • Reson8 still needs enterprise proof; one lab customer cannot sustain a sales motion.
  • Running owned European GPUs caps margins and exposes the company to hardware shortages.

What makes Reson8 unique

  • Adapter-based ASR customizes one base model in seconds, not retraining cycles.
  • Owns Netherlands-based GPU infrastructure, keeping all audio and data inside Europe.
  • Targets 24+ European languages with domain vocabularies across healthcare, legal, finance.

Reson8 collects €5M to develop europe-focused speech AI.

Reson8 collects €5M to develop europe-focused speech AI. The Amsterdam-based speech AI startup is developing highly accurate, customisable speech recognition tools for European languages, available on demand. Amsterdam-based Reson8, a speech technology company developing hyper-customised automatic speech recognition (ASR), has raised €5 million in a pre-seed round led by Balderton Capital, with participation from NP Hard. The company aims to address limitations in existing speech recognition systems, where performance often declines across European languages, dialects, and domain-specific terminology. Instead of relying on generic models, Reson8 is building acoustically precise systems that can be adapted in real time using contextual data such as documents, websites, and calendars. Its approach uses lightweight, modular adapters to tailor recognition to specific conversations without increasing latency. Founded by Thomas Kluiters, Raoul Ritter, and Jarno Verhagen, the team brings experience in high-performance systems, AI, and speech technology. The company is focused on developing models that adapt to how language is used in real-world settings, particularly in professional environments where accuracy is critical. Reson8's technology is designed for applications in sectors such as healthcare, legal, and customer support, where specialised vocabulary and fast-paced communication can challenge traditional systems. By prioritising precision and adaptability, the platform aims to reduce errors in transcription and improve usability across different use cases. Generic speech models break the moment you leave English, and customers increasingly want control over where their data lives. We believe Europe can build its own speech infrastructure that is customisable, accurate, and operated locally, In contrast to providers reliant on US-based infrastructure, Reson8 is building and operating its own European infrastructure, offering greater control over data residency and compliance with regional requirements. At launch, the platform will support more than 20 European languages. The funding will be used to expand the company's infrastructure footprint in Europe, continue development of its speech models and inference stack, and grow the team. Follow the developments in the technology world. What would you like us to deliver to you?
