TLDR: Retab, a San Francisco-based startup, has successfully raised $3.5 million in pre-seed funding to further develop and expand its document AI platform. The company aims to revolutionize document processing by providing a developer-first platform that makes large language models usable for complex, real-world workflows.
San Francisco, July 30, 2025 – Retab, an innovative San Francisco-based startup, today announced it has secured $3.5 million in pre-seed funding. This significant capital injection is earmarked to accelerate the development and expansion of its cutting-edge document AI platform, which is designed to address the challenges of processing unstructured data in the age of large language models (LLMs).
The funding round saw participation from prominent early-stage investors, including VentureFriends, Kima Ventures, and K5 Global. Notable individual investors also contributed, such as Eric Schmidt (via StemAI), Olivier Pomel (CEO of Datadog), and Florian Douetteau (CEO of Dataiku).
Retab’s platform is positioned as an essential intelligence layer that enables the world’s most powerful LLMs from providers like OpenAI, Google, and Anthropic to be effectively utilized for critical workflows. Unlike other solutions, Retab is not an LLM itself, but rather a developer platform and SDK that streamlines the entire document processing lifecycle. Developers can define the schema of the data they need, and Retab handles the complexities, including dataset labeling, evaluations, automated prompt engineering, and model selection.
Louis de Benoist, co-founder and CEO of Retab, articulated the company’s motivation: ‘People keep building demos that look like magic, but break the moment you put them into production. We lived that pain ourselves. Wiring up fragile pipelines just to extract a few fields from a PDF. We built Retab because it’s the developer-first platform we always wished we had.’
The founders, who previously built internal automation tools for document-heavy workflows in logistics, realized the true value lay in the orchestration layer they developed to make AI models work reliably. This tooling became the foundation of Retab, which is now being adopted by dozens of companies to convert messy, real-world inputs like PDFs and handwritten scans into clean, structured data.

Looking ahead, Retab plans to expand its platform to apply its reliable extraction methods to websites and integrate with popular automation platforms such as n8n, Zapier, and Dify. The company’s long-term vision is to serve as the intelligent middleware layer between the world’s unstructured data and the AI agents that need to understand and process it, making data usable, safe, and programmable for diverse applications, from loan files to customs manifests.
