What Sevis Systems does

Sevis Systems Inc. is a privately held Plano, Texas-based telecommunications software vendor founded in 1999, operating with a team of 11-50 employees. The company builds mobile identity, call verification, and anti-spoofing solutions that address declining consumer answer rates caused by mobile fraud and overly aggressive carrier spam controls. Its product portfolio centers on three offerings: eCallMe!, an anti-spoofing and call verification product aimed at enterprises seeking to improve mobile customer communication; Inbound Call Verification, a carrier-facing product that enables telecom operators to monetize network traffic through verified call authenticity; and Managed Services, a turnkey DevOps and deployment offering layered on top of both. The technology stack is positioned at the network-signaling layer, with proprietary verification systems claimed to be deeply integrated into global mobile operator infrastructure.

The company's go-to-market is consultation-driven and sales-led, with a 'Schedule a Consultation' call-to-action distributed across the corporate website as the primary conversion mechanism, supplemented by downloadable guides, newsletter signup, and direct enterprise outreach. Revenue is generated through subscription-based managed service contracts with telecommunications carriers and enterprises, though specific pricing, contract values, and revenue figures are not publicly disclosed. Customer segmentation is vertical: telecommunications carriers (described as 'global mobile network service providers') and enterprises reliant on mobile customer communications. The company does not disclose named customer logos, funding history, or ownership structure, and operates without a parent company or known institutional backing.

Operationally, Sevis runs from a single headquarters at 1201 W. 15th Street Suite 300, Plano, TX 75075, with leadership comprising Fletcher Hamilton as President and CEO, Ronnie Gomez as VP of Business Development and ASE Solution Sales, Krishna Korlepara as Director of Product Management, and Muhammad Shaiq as Chief Architect. The company maintains a global footprint claim through carrier partnerships, refreshes its branding periodically (most recently in 2024), and has no disclosed certifications, patents, or public regulatory actions on record.

Direct peers

• Hiya: Hiya is a direct competitor providing caller identification, call verification, and spam/scam protection for carriers and enterprises. Its flagship products (Hiya Protect, Hiya Connect) compete head-to-head with Sevis's eCallMe! and Inbound Call Verification offerings, serving the same telecom carrier and enterprise buyers with overlapping anti-spoofing value propositions.
• Truecaller: Truecaller is a consumer-focused caller ID and spam-blocking app with an enterprise/carrier business (Truecaller Business) addressing verified business communications. While primarily app-based, its enterprise push into verified caller identity overlaps with Sevis's anti-spoofing and call verification positioning.
• First Orion: First Orion provides call protection, caller ID, and branded call solutions for telecom carriers and businesses, competing directly with Sevis's Inbound Call Verification and eCallMe! products. Both companies focus on network-level call authentication and enterprise-branded communication trust.
• YouMail: YouMail provides call blocking, visual voicemail, and caller identification services for consumers and carriers. Its carrier-side call protection and identity services overlap with Sevis's network-level call verification and anti-spoofing offerings.

Emerging players

• Prove: Prove is an identity and authentication platform expanding from digital identity verification into voice and phone-based authentication use cases. Its phone-centric identity capabilities overlap with Sevis's call verification focus, particularly in fraud prevention for enterprises.
• TrustID: TrustID provides call authentication and caller identity verification services for businesses, particularly in financial services and contact centers. Its enterprise-focused call verification approach overlaps with Sevis's eCallMe! branded anti-spoofing offering.

Broad incumbents

• iconectiv: iconectiv operates the authoritative numbering and call authentication infrastructure used by US carriers, including playing a central role in STIR/SHAKEN call authentication. As a telecom-infrastructure incumbent, it is a broader peer whose SHAKEN ecosystem intersects with Sevis's call verification services.
• Metaswitch (Microsoft): Metaswitch, now part of Microsoft, provides telecom signaling and network infrastructure including elements related to call authentication and SIP-based services. As a broad incumbent in carrier signaling, it is adjacent to Sevis's network-level integration business.
• TransUnion (Neustar): TransUnion acquired Neustar's caller identification and robocall mitigation business, providing caller identity and authentication services to carriers. As a broader identity and risk incumbent, it competes and partners in the same call verification category Sevis addresses.
• TNS (Transaction Network Services): TNS offers call authentication, robocall detection, and signaling services to telecom carriers globally. Its Call Guardian product competes with Sevis's Inbound Call Verification and shares carrier-focused distribution channels.
