Granted builder access ([TODO: define '87,000+ access' meaning + window])
49,000+

Most builders kept their agents private.
/ THE PROBLEM
Agent builder was powerful but originally built for technical users. We needed to open it to non-technical builders without breaking the depth power users relied on. Every decision had to serve both audiences at once.
/ WHAT I BUILT
Restructured agent creation from four pages into a two-page flow ("Create" and "Settings"), reordered around how people actually think through building an agent. Redesigned the action library (seven tabs, no search, no descriptions) into a slide-out panel with fuzzy search and new categories. Added a live preview panel with a toggle for underlying code and context, so anyone could test and debug what they'd built. Redesigned the UI, implementing updated styles.
/ HOW I PROVED IT
Validated through user testing with both technical and non-technical builders, confirming the redesign held up for power users while opening the tool to newcomers. The tool was later acquired by HubSpot for its own Agent Builder, external validation of the core bet that the agent-building layer was the thing worth owning.
