Booking a meeting on a live call sounds simple. Then you try to do it without making the customer wait 30 seconds while you query a calendar API. Here's what we built.
The two-second rule
Customers expect a calendar response in under 2 seconds. Anything longer and they think the agent is broken. We pre-fetch the next 14 days of availability the moment a call starts, so when the customer says 'Tuesday 11am', we already know.
Date parsing in conversation
'Tuesday 11am' is easy. 'Sometime next week, late morning' is hard. We layer chrono.js on the transcript with a small fine-tuned model that resolves vague phrases against the customer's stated context. Accuracy is 96.4% on a held-out test set.
Round-robin done right
Cal.com's round-robin endpoint is fast, but it doesn't know that the customer-relationship is with a specific account exec. We added a 'sticky AE' override that routes to the right person 90% of the time, falling back to round-robin only when they're booked solid.
We went from 4-touch booking flows to one. The customer says yes once and they're on the calendar.
