The Organization: AngelList is the platform where GPs manage their funds, investors invest in startups, and capital moves between them. Its sales and customer support teams talk to founders, investors and law-firm partners around the world, many times a day, and every one of those conversations starts with someone finding a time.
The Challenge: The teams needed complex round-robin scheduling for sales and customer support calls, spread across a global team, and Calendly wasn't able to deliver it. Scheduling was handled by hand, took time, and let opportunities slip.
The Solution: AngelList evaluated Calendly and Chili Piper and chose Cal.com after finding it on Twitter. The move took a few hours. The hardest part wasn't Cal.com at all: it was replacing every Calendly link in the help center, the automated emails and the codebase. No customizations were needed; everything worked out of the box.

Two teams run on Cal.com today, customer support and sales, booking external meetings many times per day. Cal.com's webhooks connect bookings to AngelList's homegrown CRM and to Slack, so the rest of the company sees what was booked without anyone re-typing it.
Why Cal.com?: Two features carry the most weight. The embedded calendar on AngelList's contact page lets anyone book straight from the website. And the instant call feature, which AngelList reserves for premier customers, connects a customer or partner to the team right away instead of making them wait for a slot.
“The basic scheduling meets expectations, but the instant booking feature enables us to delight our customers and partners.”
The Impact: Time to resolution matters to AngelList's customers and partners, and instant bookings are where the difference shows: they save customers and partners the wait before speaking to someone, and law-firm partners in particular have told AngelList how much they like it. Time-zone handling and availability set-up "just work", the team is happy with the tool, and compared with what they used before the feature set is more robust and collaboration between teams inside the company is better.
“Instant bookings delight our law firm partners especially.”
The Future: Cal.com has kept up as AngelList's scheduling needs evolved, and the team would recommend it to other businesses in the industry for its overall quality and usability, and for instant bookings.
