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.

Vestico combines AI & user-generated content to show shoppers how clothes fit before they buy & collect actionable data throughout their shopping journey. Most of us don't look like the models we see online, so it's difficult to make the right decisions about size and fit. Returns in fashion e-commerce can go as high as 60% and cost retailers over $500B every year in the US alone. Far more importantly, e-commerce returns are having a devastating impact on our planet due to emissions, repackaging, restocking, and waste, with over six billion pounds of returned clothes ending up in landfill in 2019. Vestico solves the returns problem for retailers by showing shoppers how products look on people just like them. We give shoppers the confidence to buy and the information to buy intelligently, reducing returns and boosting conversion. By combining the authenticity of user-generated content with sizing AI, Vestico supports diverse representation at scale while solving the online fashion shopper's biggest pain point.

LexClaro is a multilingual AI legal-tech platform that turns complex contracts into clear, human language for individuals, freelancers and SMEs. Every year, millions of people sign rental agreements, employment contracts, shareholder agreements or service contracts they don’t fully understand. Legal language is slow, expensive to interpret and quietly shifts risk to the weaker side. LexClaro fixes that. Users upload a contract and, within minutes, LexClaro analyses it, summarises the key points and highlights obligations, rights, deadlines and risks — in their own language. No legal jargon, no guesswork, no waiting for appointments. We currently support 8+ languages and multiple contract types, designed for both personal and professional use, with a strong focus on real-world documents: housing, employment, startup equity, services and B2B deals. We’re now in Phase 4: moving from our MVP into a full SaaS web app, including live voice chat for contracts (ask questions in real time, get clear explanations plus a transcript and saved session). Next on the roadmap (Phases 5–6) is LexClaro Business: accounts for teams, role-based access, template libraries, versioning, contract comparison (original vs. edited, with changes and risk shifts clearly marked), bulk workflows and deeper integrations into HR, real estate and fintech ecosystems. The platform is currently in beta with early users testing across multiple countries. We are iterating fast on UX, language quality and legal clarity, using real contracts to improve our flows and strengthen trust. We don’t try to replace lawyers, but to become the first layer of clarity before anyone signs or negotiates — a practical legal “front door” for everyday life and business. LexClaro Global S.L. is headquartered in Spain and built from day one for international markets. On Wellfound, we’re looking to connect with growth, marketing and strategic co-founder profiles who believe in building a global brand around legal clarity.
