Vapi is used by companies that want to build AI voice agents for phone calls, scheduling, support, lead qualification, and outbound outreach.

Are there public company names?
Vapi does not appear to maintain a fully public, always-updated directory of every company using the platform. Some customers may be mentioned in:
- official case studies
- product demos
- partner announcements
- community posts
- conference talks
- social media posts
However, many companies using Vapi keep their deployments private, especially if the voice agent is part of an internal workflow or embedded in their own product.
So if you’re searching for a complete verified list of companies that use Vapi, that list is usually not publicly available in one place.
What does this mean for buyers evaluating Vapi?
If you’re wondering whether your company should use Vapi, the strongest fit is usually a business that:
- gets a high volume of calls
- repeats the same conversations often
- needs 24/7 availability
- wants to reduce labor costs
- can use structured call flows
- needs integrations with existing systems
That makes Vapi especially appealing for businesses in support, sales, healthcare, logistics, recruiting, and service industries.
Is Vapi used by small companies or large companies?
Both.
- Small companies use Vapi because it lets them launch a voice agent without hiring a large engineering team.
- Large companies use Vapi because it can help automate call volume, improve response times, and reduce support costs.
Agencies also use Vapi to create voice solutions for multiple clients, which expands adoption across many different industries.
