Kuwalyst is the marketing strategy operating system for brands that refuse to fly blind.

Most companies spending millions on marketing can't prove which channels actually drive results. Attribution is broken, consultancies deliver one-off audits that gather dust, and the gap between insight and action is where budgets get wasted. Kuwalyst closes that gap, permanently.

We built an agentic platform that diagnoses, experiments, and optimises marketing performance autonomously. Not another dashboard. Not another reporting tool. A closed-loop system that connects to your sales, campaign, and customer data, runs a scored marketing health audit, delivers weekly tactical reports that tell you what to do (not just what happened), and continuously proposes and validates experiments to improve performance.

What sets us apart is real marketing science. We combine Marketing Mix Modelling, multi-touch attribution, geo-experiments, incrementality testing, and causal inference into a single platform, powered by LLMs fine-tuned specifically for marketing measurement. In benchmarks against off-the-shelf models like Claude Opus 4.6, Kuwalyst's ROAS estimations were within range of ground truth while the general-purpose model was off by an order of magnitude.

We are EU-sovereign by design. Our models are open-weight, hosted in France through a partnership with Scaleway, and can be deployed on your own infrastructure. No data leaves your environment. No US Cloud Act exposure.

Kuwalyst was founded in Paris by Julien Bourdon-Miyamoto (20+ years in AI/ML, ex-Meta Staff ML Engineer) and Hajime Takeda (10 years in marketing science across retail and fashion in the US and Japan). We are currently selecting design pilot partners who want to move from guesswork to evidence.

Make your marketing spend work harder. With science, not guesswork.
