The Blacklist Alliance

What The Blacklist Alliance does

The Blacklist Alliance operates a cloud-based TCPA and DNC compliance platform serving businesses engaged in high-volume telemarketing, SMS marketing, and automated communications. The company serves five primary verticals: contact centers, digital marketers and lead-generation networks, insurance and Medicare companies, VoIP carriers, and AI/automation users operating under the FCC's February 2024 AI-voice ruling. Approximately 1,000 clients use the platform across these segments, with no public enterprise logos disclosed in the source material.

The core technology is an API-first platform that performs real-time screening of phone numbers against the federal Do Not Call registry, all state DNC lists, and a proprietary database of known TCPA litigators and serial plaintiffs that is updated continuously. The flagship "Litigation Firewall" automatically blocks risky numbers inside customer dialers or VoIP platforms before calls connect, and the platform documents consent and call outcomes automatically. Supporting products include Caller ID Reputation monitoring across major carriers, NumberVerifier (carrier, line-type, and ported-status data via API), Legal Support services for TCPA defense, online Compliance Training, and Compliance Support audits and policy documentation. The system runs on Google Cloud infrastructure and integrates with major VoIP platforms (Twilio, Plivo, Vonage, RingCentral), dialers (Convoso, Plura), lead-generation systems (Linktrust, Leads-pedia, Phonexa, Boberdoo, Retriever), and workflow automation tools (Zapier, Make).

The company generates revenue through annual subscriptions priced on a custom enterprise basis tied to call volume and feature requirements, with no publicly disclosed pricing tiers. Sales follow a demo-driven enterprise field motion in which prospects book a free 30-minute consultation showing the Litigation Firewall against their own call flow before receiving a custom quote. The Blacklist Alliance, Ltd. is a privately held California company headquartered in Carlsbad with 11-50 employees and no disclosed revenue, funding, or ownership structure. A "TCPA Litigation Firewall" registered service mark is on file.

Expansion highlights6 records

Broad incumbents

• Convoso: Convoso is a leading outbound dialer platform and Blacklist Alliance integration partner; while primarily a dialer, it increasingly embeds compliance features that could overlap with Blacklist Alliance's litigation firewall functionality.
• Hiya: Hiya is a major caller-ID reputation and spam-screening provider serving carriers and enterprises globally. It overlaps with Blacklist Alliance's Caller ID Reputation product and competes in the broader voice-trust-and-safety category.
• First Orion: First Orion provides caller-ID reputation, call-blocking, and scam-protection services to carriers and enterprises, overlapping with Blacklist Alliance's caller-ID reputation and TCPA compliance offerings at the carrier-integration layer.

Emerging players

• YouMail: YouMail provides robocall blocking, caller-ID, and telecom fraud prevention for consumers and carriers. It competes in the adjacent fraud/abuse-prevention space that frames Blacklist Alliance's outbound compliance mission.
• Nomorobo: Nomorobo offers real-time robocall blocking and call-screening for consumers and carriers, addressing an adjacent slice of the TCPA/abuse-prevention category that Blacklist Alliance serves on the outbound-caller side.
• TrustID: TrustID provides phone-number intelligence, caller authentication, and risk scoring for contact centers. Its number-verification and line-type data overlap with Blacklist Alliance's NumberVerifier/Data Optimization product line.

Direct peers

• ActiveProspect: ActiveProspect (TrustHub/LeadConduit) provides TCPA-compliant consent management and lead verification for the lead-generation ecosystem, a closely adjacent offering to Blacklist Alliance's litigator scrubbing and consent documentation services.
• Gryphon Networks: Gryphon provides TCPA compliance, DNC scrubbing, and outbound call governance for enterprises, cited by The Blacklist Alliance as a direct point-solution competitor. Both target the same contact-center compliance buyer with overlapping functionality.
• DNC.com: DNC.com is a DNC registry scrubbing and telemarketing compliance service that The Blacklist Alliance explicitly names as a direct competitor. Both serve contact centers and outbound dialers with similar scrubbing workflows, differing mainly in Blacklist Alliance's proprietary litigator database overlay.
• PossibleNOW: PossibleNOW delivers DNC and contact compliance solutions for enterprise marketing and contact center operations, also named as a direct competitor by The Blacklist Alliance. Both occupy the same TCPA/DNC compliance software category for high-volume callers.
