Our voice and WhatsApp agents already qualify clients, generate documents, manage cases, and handle billing workflows, delivering over 2× improvement in lead conversion for our customers. We've gone from idea to revenue in months: + Multiple paying law firms onboarded + Six-digit ARR + Daily usage (+200 calls/WhatsApps) by real customers + Clear PMF in a massive, fragmented €5B+ market (in Spain alone) As a co-founder, you'll be in the driver's seat-shaping the vision, setting the pace, and taking ownership.

You've built with modern LLM tools-agent orchestration, RAG, embeddings-and know what works in production. + Curious and smart. You track new research and apply what's useful. + User-value focus. You measure success by customer impact and time saved, not vanity metrics. + Ownership mindset.

You pick simple solutions, automate routine tasks, and release early and often. + Team builder. You attract and develop strong engineers and foster a supportive, high-standards culture. + Clear communicator. You explain technical trade-offs to both engineers and non-technical stakeholders. What We Offer + Day-1 founding seat. Jump into an ambitious startup from the ground up, with a validated concept and live pilots. + De-risked upside. Build as a co-founder on a path charted by Antai's successful venture-studio model-capital, playbooks, and network included. + Full-stack operator support.
