About

Why Annsa exists.

Big product questions deserve better answers. Annsa is the product intelligence system for growth — carrying customer evidence across teammates, decisions and agents.

Customer evidence should travel.

What customers say, need and do arrives through conversations, support, analytics, sales calls and product behavior. But its context is often lost as it moves between people, tools and decisions. Now the same fragmentation is happening across the AI agents helping teams research, decide and build.

Our mission: Make customer evidence the intelligence behind every product decision.
Across every teammate, tool and agent.

Values.

THE FOUNDER

Built by Catherine Williams-Treloar.

20 years across customer research, product and growth.

CATHERINE WILLIAMS-TRELOAR
“The methods were never good enough.”
Solo-founded in Sydney in 2025. Launched February 2026.

I've spent 20 years turning customer evidence into product and growth decisions — at WPP, across 220+ global markets at Intuit, and through the growth of TradeGecko. I thought the problem was collecting better feedback. The methods were never good enough.

Speaking to teams changed my mind. They already had feedback, analytics and customer context. The real problem was that the evidence didn't travel. What one person learned stayed in their notes, tools or memory. Every decision began with another search for context. Now the same thing is happening across the AI agents helping teams research, decide and build. That's why I built Annsa.
