Numeracle raises $28M to stop real business calls being flagged as spam

Numeracle, a Virginia company that helps legitimate businesses avoid the spam label, has raised $28 million from Edison Partners. The money is meant for businesses whose calls are wrongly marked as spam or blocked by phone carriers. If you have ever ignored a call because your phone showed a fraud warning, this is the problem the company is trying to fix.

What Numeracle does

Numeracle first checks that a business is real and does what it says it does. Once a business passes, the company links it to the phone numbers it uses. It then shares that information with the systems carriers use to flag or block calls, and works to remove incorrect labels.

Customers pay an annual subscription for monitoring and fixing wrong spam labels. They can also pay a fee per call to show their business name, logo and reason for calling on the recipient's phone.

Why it matters

Businesses face two problems at once. Fraudsters increasingly pretend to be real companies, and call-screening tools can keep real calls from getting through. The article gives two examples: a patient ignoring a hospital call about an upcoming procedure, and a bank customer declining a real call because of a fraud warning.

The numbers

Numeracle says it has roughly 4,000 business customers and about 85 employees. It became profitable this year, sooner than CEO Rebekah Johnson expected. Total funding is now $34.8 million since the company started in 2018. That includes a $6.8 million Series A, an early funding round, raised in December 2023. Edison was the only investor in the new round. The valuation was not disclosed.

One contact center operator told Edison that answered calls rose from 19,000 to 22,000 out of 40,000 calls a month after using Numeracle. That is one customer's account, not a broad study.

Fake businesses are getting harder to spot

Fraudsters have a reason to try to pass Numeracle's checks, because approval makes their calls less likely to be flagged. Johnson says AI has made it harder to tell which businesses are real. Numeracle has found fake companies with state registrations, employer identification numbers and supposed employees with active LinkedIn profiles.

"The scary part for me isn't necessarily the AI voices," Johnson said. "It's actually AI-built businesses." Numeracle uses AI to catch these fakes, but she declined to explain how.

What happens next

Numeracle plans to hire, expand internationally and adapt its verification tools beyond phone calls. Johnson named messaging, chat apps, marketplaces and AI agents as possibilities. The company works only in the United States today, but interest from Europe is pushing the expansion forward.

The open question is whether businesses will pay for verification outside of phone calls. Johnson also declined to name individual customers, so the claims about results are hard to check independently.
