Ever wished you could capture the rich insights of a live, one-on-one conversation—without the hassle of scheduling calls?
As a solo consultant and founder of GSD at Work, I collaborate with clients across the globe. One of my biggest challenges? Intake. I need deep, contextual insight before running my high-impact workshops—but scheduling discovery calls with dozens of participants across time zones was becoming a bottleneck.
That’s when I found Vapi—and everything changed.
My core offering is something I call AI Action Sessions—intensive, hands-on workshops where teams accomplish in two hours what might otherwise take weeks. But for these sessions to truly land, I need detailed input from every participant.
Traditional intake forms and surveys rarely offer the nuance or emotion of a real conversation. And scheduling live calls with every stakeholder? A logistical nightmare.
By integrating Vapi into my process, I’ve created a completely asynchronous voice intake system. Participants call in when it's convenient, respond to my guided prompts, and I get instant transcripts and summaries—ready to be actioned.
If you're looking to bring efficiency and insight to your client workflows, I can’t recommend Vapi enough.

For a recent client, 20 participants—spread across the globe—engaged with my Vapi-powered intake process. In total, over 3 hours of detailed discovery happened asynchronously, on their own time.
The result?
A 5 out of 5 rating across the board—making it the highest-rated session of the conference.
That’s no accident. The insights I pulled from those voice transcripts allowed me to craft a workshop that felt bespoke to each person in the (virtual) room.
With Vapi, I’ve struck a rare balance: less friction, more depth. My process is leaner, my prep is sharper, and my sessions are more impactful.
Clients walk away feeling heard—and energized. I walk in fully prepared, without the chaos of back-to-back Zooms.
I'm already exploring how this voice-powered intake model can scale into new areas:
From onboarding financial services teams to screening job applicants, Vapi is now an essential part of my consulting toolkit.
