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.

Law firms lose clients not because of weak marketing, but because of what happens in the seconds after someone calls or messages. A missed call at 9pm, a form that sits unread until Monday, a receptionist juggling three lines at once — and the caller just moves on to the next firm. Lexidesk fixes that gap. It's an AI intake platform built specifically for consumer-facing law firms — family law, immigration, personal injury, criminal defense, estate planning. It answers every call and website enquiry around the clock, runs a real qualifying conversation instead of a static form, scores each lead by priority, and either books the consultation, live-transfers the urgent ones, or follows up automatically if nobody books right away. Everything syncs straight into the firm's existing systems: Clio, HubSpot, Lawmatics, HighLevel. We built it around one observation that kept coming up in conversation after conversation with firm owners: most law firms don't have a lead problem, they have a response problem. Demand is already there. What's missing is a system that can be trusted to represent the firm the moment someone reaches out, at any hour, without adding headcount. Lexidesk now runs intake for 50+ law firms across the US, UK, and Canada, from solo practices to firms with dozens of offices. We're a small, remote-first team that ships changes fast — every update to an intake agent goes through simulated call testing before it reaches production, because a law firm can't afford an AI mistake with a real client on the line.
