Imagine the typical knowledge worker's day in 2025: bouncing between a dozen specialized AI tools, each siloed in its own ecosystem. One platform for document summarization, another for meeting transcription, a third for writing assistance, and yet more for translation, search, and other AI-powered tasks.
The result is fragmented workflows, subscription fatigue, and a productivity promise that remains frustratingly unfulfilled.
This is the problem that Paris-based startup Delos aims to solve. Founded by brothers Pierre and Thibaut de la Grand'rive in summer 2023, Delos has developed what amounts to an operating system for artificial intelligence in the workplace – a sovereign, unified platform that orchestrates multiple AI models into a coherent experience. The company unveiled the platform last week and also announced a €2.5 million fundraising.
In a landscape dominated by American tech giants and specialized point solutions, Delos believes it can succeed by reimagining the entire workspace as a natively AI-powered environment where technologies work together rather than competing for the user's attention. Delos.so orchestrates multiple AI models (including ChatGPT, Claude, Mistral, and Llama) into a cohesive platform with seven integrated applications.
"We started from scratch. Rather than adapting our work methods to AI, we built an AI adapted to our work methods," said CEO Pierre de la Grand'rive. "Our ambition is to offer generative AI that is truly useful to employees."
Building an All-in-One AI Platform
A Polytechnique graduate who studied advanced algorithmics and quantum computing, Pierre brings technical expertise to complement his brother Thibaut's commercial background.

Delos didn't start with a platform approach. "At the beginning we went to companies to develop some custom development based on generative AI. And it came to us that companies needed an integrated solution," Pierre said.
This insight led to the creation of Delos.so, which focuses on orchestration rather than developing its own large language models (LLMs). This orchestration approach significantly reduces costs by dividing the inference cost for each task.
"We are not developing our own LLMs. It costs too much, and at the moment, you have a lot of models on the market. So we are orchestrating them, taking the best of each," Pierre said.
Delos sees the current AI productivity market segmented into three categories: model creators focused on training LLMs, established tech giants trying to integrate AI into existing workspaces, and specialized startups focusing on narrow applications.
"We see all of the new players that take one use case as one piece of a big puzzle," Pierre explains. "We don't believe that if you just focus on one piece, it will work. We believe that what we are trying to do is to build a coherent workspace that will gather all these pieces."
Delos combines seven features:
- Assistant - A secure, multipurpose AI assistant that interacts with various AI models on the market through their proprietary orchestration technology.
- Docs - A drive where users can dialogue with documents, extract precise data, and generate summaries. The system includes their "autonomous drive" innovation that automatically names, classifies, and summarizes files.
- Scribe - A personalized writing assistant powered by AI.
- Recap - Automatic meeting minutes compatible with all platforms and recording types, including integration with Zoom, Teams, and other meeting platforms, plus microphone support for in-person meetings.
- Explore - An AI-powered search engine that searches the internet for users and returns relevant information.
- Trad - An instant and contextualized translation tool that provides translations adapted to a company's specific language, with capabilities to translate documents and PowerPoints instantly while maintaining perfect formatting.
- News - A newsletter generation and personalized monitoring tool.
Pierre explained that while many other companies are launching similar sets of featrues, Delos' advantage is the way it combines all of these pieces into a unified experience. That means employees don't have to juggle between a dozen specialized applications for different AI tasks, which requires significant learning and costs. The company's pricing model is competitive at €25 per user per month, strategically positioned against Microsoft's Co-pilot.
Delos has built proprietary orchestration technology that coordinates different LLMs available through the platform to find the most suitable one for a task. All of the data is hosted in France via a partnership with Scaleway.
In addition to these core features, Delos announced three additional advancements last week:
- Structured Memory System - A new generation of memory with six dimensions including user profile, company profile, deep memory of past interactions, and reminders.
- Autonomous Document Drive - A system that automatically names, classifies, and summarizes documents,
- Voice-to-Computer Technology (Alma) - An interface that allows users to control the entire platform through voice commands without typing.
"You can control your computer by voice, without tapping anything," said Pierre, comparing it to Jarvis system from Iron Man. "We don't know for the moment exactly how it's going to integrate in the world of business, for sure, because it's a massive change."
Funding and The Road Ahead
The €2.5 million fundraising round announced in April 2025 was led by British fund 20VC, with participation from founders of prominent French tech companies Pigment, Dataiku, and Hexa, as well as funds like Inovia, Plug-and-Play, and Kima Ventures.
This funding will support Delos' commercial expansion and product development, Looking ahead, Delos priorities include expanding in France, entering the US market within the next 6 months by leveraging connections from investors like the CEO of Dataiku, and accelerating product development. Current plans include adding calendar and email functionalities to make the workspace more comprehensive.
"In generative AI, it's a speed run," Pierre said. "You have to be always in front of innovation. If you don't go at this pace, I think you're dead in generative AI."
