Numeracle, a McLean, Virginia-based technology company dedicated to solving the widespread issue of legitimate business calls being incorrectly flagged as spam or blocked outright by phone carriers, has raised $28 million in a new funding round led exclusively by Edison Partners.
The latest financial injection brings Numeracle’s total funding to $34.8 million since its inception in 2018. This cumulative total includes a previous $6.8 million Series A funding round secured in December 2023. Founder and CEO Rebekah Johnson confirmed the details of the transaction, though the company has opted to keep its overall valuation private.
Operating with a team of approximately 85 employees, Numeracle currently serves roughly 4,000 business customers across a variety of critical sectors. Notably, the enterprise reached profitability earlier this year, a financial milestone that arrived significantly sooner than Johnson had initially projected.
With fresh capital now secured, Numeracle plans to aggressively accelerate its hiring initiatives and pursue international expansion. Furthermore, the company intends to adapt its proprietary business verification technology so it can be applied to communication channels stretching far beyond traditional phone calls. According to Johnson, the organization is actively eyeing opportunities in messaging, chat applications, digital marketplaces, and AI-driven automated agents.
This strategic expansion unfolds as businesses navigate a complex, dual-sided crisis in modern telecommunications. On one hand, malicious actors are increasingly sophisticated in their attempts to impersonate legitimate enterprises. Simultaneously, automated call-screening systems deployed by carriers to thwart these fraudsters often cast too wide a net, accidentally preventing legitimate communications from reaching everyday consumers.
The everyday ramifications of this friction can be severe. For instance, a patient might ignore an urgent phone call from a hospital regarding an upcoming medical procedure because their mobile device flags the call as potential spam. Similarly, a banking customer might decline a legitimate fraud-prevention alert from their financial institution because a warning label appears on the screen.
To combat these challenges, Numeracle operates on a dual-revenue model. The company charges businesses an annual subscription fee to continuously monitor and remediate incorrect spam labels across carriers. Additionally, clients can opt for a per-call fee structure that displays their official business name, corporate logo, and a verified reason for calling directly on the recipient’s mobile screen.
From a Regulatory Warning to an Industry Solution
The origin of Numeracle is deeply rooted in Johnson’s professional background as an engineer and regulatory compliance expert at telecom provider West Technology Group. The core concept for the company crystallized in 2016 while Johnson was participating in the Federal Communications Commission’s Robocall Strike Force.
During her tenure with the initiative, Johnson issued a direct warning to telecom carriers: their aggressive efforts to identify and intercept unwanted robocalls would inadvertently ensnare legitimate businesses. She argued that the screening systems being implemented lacked any reliable mechanism to verify the true identity of the caller.
Roughly three months later, that warning materialized. Johnson was standing in her parents’ kitchen when she received a phone call from a carrier’s federal regulatory counsel.
"Everything you said was going to happen is happening. What do we do?" she recalled the attorney asking.
That pivotal conversation served as the catalyst for launching Numeracle. At the time, Johnson was a newly single mother who had recently lost her job. Operating without a financial safety net, she invested her entire life savings into founding the venture. Living on a remote farm in Grand Bay, Alabama, which lacked internet access, she was forced to conduct business operations from local cafes.
"When you need to feed your children and provide a roof over their head, you’re going to count every penny," Johnson reflected.
That bootstrap mentality profoundly shaped Numeracle’s fiscal discipline as the company scaled. The organization successfully operated and sustained itself for several years before ever raising its initial Series A round. Today, Johnson notes that approximately 90% of Numeracle’s sales inquiries arrive organically through unpaid inbound channels. With the influx of capital from Edison Partners, the company plans to increase its financial outlay for targeted marketing campaigns tailored to specific industries, most notably healthcare.
Beyond healthcare, Numeracle’s diverse client roster includes organizations operating in financial services, home services, higher education, government administration, and charitable sectors. While Johnson declined to name specific enterprise clients due to confidentiality agreements, the broad utility of the service underscores its cross-industry relevance.
Verifying Increasingly Convincing Fakes
At its core, Numeracle functions by establishing a rigorous trust bridge between enterprises and telecom infrastructure. The company first performs comprehensive background checks to confirm that a business is legitimate and genuinely performs the services it claims to offer. Once an entity passes these stringent verifications, Numeracle cryptographically links the business to the specific phone numbers it utilizes to contact consumers. This verified identity data is then shared directly with the screening systems that carriers rely on to evaluate incoming traffic.
In addition to protecting outbound communications, third-party enterprises can pay Numeracle to perform these same verification checks on external businesses they are considering onboarding as customers or partners.
Johnson emphasized that Numeracle was forced to build its own proprietary verification infrastructure because existing market solutions lacked the necessary thoroughness. The incentive for fraudsters to bypass these security measures is remarkably high; if an unauthorized entity manages to pass Numeracle’s checks, their illicit calls become significantly less likely to be flagged or blocked by carriers.
The rise of generative artificial intelligence has compounded these challenges, making it increasingly difficult to differentiate between authentic enterprises and elaborate scams. Johnson noted that Numeracle has encountered fraudulent entities equipped with legitimate state registrations, valid employer identification numbers, and elaborate networks of supposed employees boasting active, fully fleshed-out LinkedIn profiles.
"The scary part for me isn’t necessarily the AI voices," Johnson said. "It’s actually AI-built businesses."
To combat this evolving threat vector, Numeracle utilizes its own advanced artificial intelligence systems to help detect and flag these sophisticated fabrications, though leadership declined to disclose the proprietary mechanics behind those detection methods.
While Numeracle’s operations have primarily centered on the United States market, surging interest from international regions, particularly Europe, has accelerated the company’s global ambitions. A portion of the new capital from Edison Partners has been earmarked specifically to support this international rollout.
Ultimately, the broader question for the company is whether enterprises will embrace its verification services across emerging communication formats. For the present, however, Numeracle remains focused on solving a vital and immediate market problem: ensuring that when a business calls a customer, the recipient can trust that the call is real.
Investor Perspective: Doing More With Less
For Lenard Marcus, a general partner at Edison Partners, Johnson’s extensive engineering background and deep-rooted expertise in the telecom sector served as primary drivers for the investment. In an interview, Marcus explained that her industry knowledge allowed her to construct both a resilient technological product and the crucial foundational relationships needed to introduce it to major enterprise buyers.
Marcus was equally impressed by what Numeracle managed to achieve with minimal outside funding prior to this round, characterizing Johnson as a leader who consistently demonstrated an ability to do more with less.
Due diligence interviews with enterprise clients further reinforced the investment thesis. Marcus recalled feedback from a contact center operator who reported that Numeracle’s intervention successfully increased the number of answered customer calls from 19,000 to 22,000 out of a monthly volume of 40,000. For businesses heavily reliant on phone outreach to acquire and retain customers, that measurable uptick in completed conversations translates directly to improved operational efficiency and higher revenue generation.
Marcus also expressed confidence that Johnson’s years of experience within the telecom ecosystem provide Numeracle with an insurmountable competitive moat against newer market entrants. Beyond understanding the intricate mechanics of the industry, Johnson’s established network has proven instrumental in securing executive-level access at major corporations.
"She’s sales. She’s engineering, and she’s just a very, very good leader," Marcus noted.
Looking forward, the investor anticipates robust demand across healthcare, retail, home services, and financial services, especially as artificial intelligence continues to lower the barrier for sophisticated corporate impersonation schemes.
"This is a communications problem, not one for one industry," Marcus concluded.
