Case Study: Instawork scales candidate screening 50x with Vapi
Key results
The challenge
Instawork manually conducted every screening call for its labor marketplace, causing cost to scale linearly with demand and quality to vary during peak volumes. Existing tools could not support high-volume, real-time voice interactions across platforms.
The solution
Instawork deployed Vapi's voice AI platform for engineering control over agent logic and models, with dashboards for non-technical teams. Vapi's forward-deployed engineering support enabled rapid deployment.
“Vapi has been a great partner for Instawork. Their platform allowed us to scale to millions of calls reliably with no performance issues, while giving our engineering, product, and operations teams a powerful and flexible way to build and manage voice agents.”

The results, in context
Vapi reports a 50x increase in screenings, a +30% increase in successful skills matching, 30 days from concept to production, and 85% lower cost per call, with millions of calls handled at scale. These figures are quoted from Vapi's Instawork customer page and dated to that public source.
