Vox

Why I built this

Our investment team was spending hours on introductory calls with founders — calls that mostly followed the same script. The high-value work was in the follow-up conversations, not the initial screen. I built Vox to handle the first call autonomously: pull the founder's application data, ask contextual questions, and log a structured evaluation. This freed the team to focus on the founders who made it past the initial filter.

What it does

Vox is an autonomous voice call system for conducting founder interviews at scale. An ElevenLabs voice agent calls founders via a shareable link, pulls their application data from Airtable mid-conversation to ask contextual follow-up questions, then logs the full transcript and structured feedback.

How it works

1. A shareable call link is generated per founder
2. The frontend requests a signed ElevenLabs session
3. The voice agent starts and invokes a tool to fetch the founder's application context
4. After the call, a webhook captures the transcript and structured evaluation

The system was deployed with professional voice clones for 18 team members, handling first-call outreach and freeing the investment team for high-signal conversations.
