Why You Should Join Rippletide — Now
Timing matters in a career as much as it does in a market. Joining a company at the right moment, when the problem is defined but unsolved, the team is small but funded, and the market is ready but underserved, is how outsized impact happens. That moment is now at Rippletide. Here is why.
The Problem Is Hard and It Matters
We are building a hypergraph-based decision database that gives enterprise AI agents the ability to reason, not just retrieve. This is not incremental improvement on an existing product category. It is new infrastructure for a new class of software. The technical challenges are real: encoding complex relational knowledge into hypergraph structures, maintaining reasoning accuracy at enterprise scale, and building agents that can explain their decisions in terms that business users trust.
If you are the kind of engineer or researcher who is drawn to problems that require inventing new approaches rather than applying existing ones, this is the work you have been looking for. The field is wide open, and the decisions you make now will define the architecture for years to come.
The Team Is Exceptional and Still Small
Rippletide was founded by Yann Bilien and me in early 2024. We raised a four-million-euro seed round from OneRagtime and built a team that spans graph theory, machine learning, distributed systems, and enterprise go-to-market. The team is small enough that every person has a direct impact on the product and the company's direction. There are no layers between you and the work that matters.
Small also means that the people you work alongside right now will be the people who define the company's culture and technical DNA for the long term. Joining at this stage is not just taking a job. It is shaping an institution.
The Market Is Ready
Enterprises have spent the last two years experimenting with large language models and discovering their limitations. Hallucinations, lack of explainability, and brittle retrieval pipelines have created a market that is actively searching for a better approach. Rippletide's architecture addresses these problems structurally, not with patches. The conversations we are having with enterprise buyers today are not about whether they need what we are building. They are about how fast we can deliver it.
What We Look For
We hire people who combine deep technical ability with intellectual honesty. People who would rather be right than be comfortable. People who can hold strong opinions loosely and update their thinking when the evidence demands it. If you thrive in environments where autonomy is high, problems are ambiguous, and the standard is excellence, Rippletide is built for you.
We have offices in Paris and San Francisco. We are hiring across research, engineering, and go-to-market. If any of this resonates, reach out. The window for joining at this stage will not stay open forever.
