Spencer Levitt and Austin Pager met early on as classmates at Northwestern University and spent the next several years building apps powered by a wide range of APIs. After developers kept tapping them to help with API integrations, they set out to build a tool for “API-first” companies to offer simpler integration experiences.

“During Y Combinator, which we participated in after graduating from Northwestern a year early, an early adopter started using our tool to aid their sales process instead,” Levitt and Pager told TechCrunch via email. “He realized it was a great way to explain the value of his software to potential buyers. This was our ‘aha’ moment.”

Levitt and Pager co-founded Coast, a platform that enables a sales team to demo its company’s APIs via a dashboard that executes live requests visually and in the browser. Using Coast, sales teams can showcase what prospects can build on top of APIs — personalized to a given prospect’s brand and use case.

Certainly, there’s other software demoing platforms on the market — many with substantial VC backing. Demostack, a startup developing a service that lets SaaS companies quickly create product demos, raised $34 million last April. Meanwhile, Consensus, a company developing an automation platform for SaaS product demos, recently nabbed $110 million. Other noteworthy vendors include Arcade, Demodesk and CloudShare.
