Brain health today is invisible and inaccessible. Over 300 million people live with untreated or misdiagnosed cognitive conditions, facing long waiting lists, fragmented specialists, and high out-of-pocket costs. Unlike physical health, there is no routine panel for the brain. Connectome solves this by making brain insights as accessible as a blood test — turning the brain into a routine, trackable part of whole-body health, and building the world’s largest longitudinal brain dataset in the process. At its core Connectome is a fast, non-invasive brain scan that produces a standardized panel of metrics. These power our predictive ML engine, and lifestyle alignment score that integrates wearables and behaviour data. Together, they make brain health measurable, optimisable, and scalable through clinics, wellness centers, and digital health partners.

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.
