Numeracle raises $28M for call verification

Highlights

Numeracle raised $28 million from Edison Partners, bringing total funding to $34.8 million since 2018, while declining to disclose its valuation.
Numeracle reached profitability in 2024, serves about 4,000 business customers, and plans to use new capital for recruitment, international expansion, and product adaptation for messaging and AI channels.
Increasing AI-driven call impersonation and fraud have fueled demand for Numeracle’s business call verification services across healthcare, finance, retail, and home services sectors.

Funding backs growth in call authentication

As first reported by Crunchbase News, McLean, Virginia-based Numeracle has secured $28 million from Edison Partners to help businesses whose calls are wrongly labeled as spam or blocked by carriers. The round brings the company’s total funding to $34.8 million since its 2018 launch, including a $6.8 million Series A raised in December 2023, while Numeracle declines to disclose its valuation.

Numeracle says it verifies businesses and connects their identities to the phone numbers they use to contact customers, then shares that information with the systems carriers rely on to screen calls. The company says it serves about 4,000 business customers, employs roughly 85 people and becomes profitable this year, earlier than founder and Chief Executive Rebekah Johnson expected.

The new capital is set to fund recruitment and international expansion, with Europe drawing particular interest, according to Johnson. Numeracle also plans to adapt its verification tools for messaging, chat apps, marketplaces and AI agents, broadening a model that now centers on helping legitimate calls reach consumers.

Fraud concerns widen demand across industries

Numeracle’s pitch targets a growing problem for sectors such as healthcare, finance, home services and higher education, as well as government groups and charities. A mislabeled call can mean a patient ignores a hospital reminder or a bank customer declines a real outreach attempt after seeing a fraud warning on a phone screen.

The company charges an annual subscription to monitor and correct spam labels, while offering a per-call product that can display a business name, logo and reason for calling on a recipient’s device. Johnson says about 90% of Numeracle’s sales inquiries come through unpaid inbound channels, though the company now plans to invest more in industry-focused marketing, including healthcare.

Johnson says she identified the issue while serving on the Federal Communications Commission’s Robocall Strike Force in 2016, where she warned that call-screening systems lacked enough information to distinguish legitimate businesses from unwanted callers. She says AI now makes that challenge harder because fake companies can appear more credible, sometimes with state registrations, employer identification numbers and supposed employees with active LinkedIn profiles.

Edison Partners says Numeracle’s progress with limited capital was a key factor in its investment decision. General partner Lenard Marcus says customer feedback showed measurable gains in answered calls, and he sees demand spreading across healthcare, retail, home services and finance as AI-driven impersonation becomes more common.

Our earlier report on Q3 cybersecurity funding highlighted how investment stayed resilient as larger late-stage rounds pushed total capital higher even while overall deal counts fell. We also noted that AI-focused and identity security companies attracted the biggest checks, alongside increased M&A as the industry consolidated to address escalating AI-era fraud risks.
