In this episode of Agents at Work, Jordi Montes sits down with Thais Castello, Head of Marketing & Strategy at Exa.ai, the company building the first search engine designed for AI agents.

They explore:

• Why LLMs need a new kind of search (and why Google won’t cut it)

• How semantic search turns the web into a “queryable database” for AI

• The role of speed, privacy, and customization in powering agent workflows

• What it takes to build search infrastructure for AI at web scale

• Why the future of AI depends on marrying intelligence with knowledge

Thais shares Exa’s vision for the next generation of search, built not only for humans, but for machines. She also dives into the creativity of their customers, the research breakthroughs behind Exa’s tech, and why performance is becoming the biggest bottleneck for AI systems.

If you’ve ever wondered how AI agents actually find the information they need, or why search is quietly becoming the foundation for the next wave of AI, this episode is a must-listen.
