Top SEO Startups in Europe

We are building the definitive visibility and optimization infrastructure that ensures businesses get found, ranked, and recommended across ChatGPT, Gemini, Claude, and modern AI search engines. While we currently deliver this as a high-margin enterprise service with undeniable ROI, we are actively building out the workflows to transition our proprietary methodologies into a scalable, automated SaaS platform. The way the world finds information has changed forever. Customers are no longer scrolling through pages of traditional blue links on Google; they are asking AI platforms for direct, instantaneous business recommendations. If a company is not the top recommendation when a potential customer asks ChatGPT, they effectively cease to exist in the modern AI era. Every business owner knows they need to adapt to this massive shift, but 99% of them have absolutely no idea how AI models evaluate data or how to influence them. We have cracked the code on AI optimization. We solve the critical, high-stakes problem of customer acquisition in an AI-driven market, turning a technical headache for businesses into an automated competitive advantage.

Splitsense is building an AI agent that does conversion optimization the way a senior CRO specialist would, end to end and continuously. The problem we're solving is one every founder and growth team knows. You have analytics, heatmaps, session recordings and dashboards, but none of them tell you what to actually do. Turning that data into insight takes hours of digging. Turning insight into an experiment takes developer time most teams don't have. So most websites never get optimized at all, and the ones that do run a handful of tests a year instead of a steady stream. That's a hard problem because good CRO isn't one skill, it's a pipeline of them: reading funnels and spotting where users drop off, forming hypotheses worth testing, writing copy that converts, building variants without breaking the site, running the statistics honestly, and knowing what to test next. We're encoding that entire pipeline into autonomous agents. Splitsense crawls your site, learns your brand and audience, analyzes real visitor behavior through its own analytics and session replay, finds the leaks, then writes, launches and measures A/B tests on its own. Multi-armed bandits shift traffic to winners while tests run, so learning turns into revenue faster. The result: the kind of continuous experimentation program that used to require a CRO consultant, a copywriter, an analyst and an engineer, now available to a solo founder for the price of a SaaS subscription. We're a small, senior, fully remote team that ships fast and uses our own product on our own funnel every day. If you want your work to compound, everything we learn makes the agent smarter for every customer.
