Sublynk

Sublynk operates a single B2B network in which every member business — contractors, subcontractors, general contractors, industry networks, carriers, third-party administrators (TPAs) and property managers — must pass verification before joining. Vetting covers business verification (tax ID confirmed with the IRS, Secretary of State records), license validation with the state, insurance confirmation with the broker, and background checks run via Checkr, with continuous monitoring of credentials afterward. The company states verification is completed in about one business day.

On top of vetting, the platform provides subcontractor management (live compliance, credentialing and onboarding status across a roster), vendor management with expiration flags 30 days ahead of renewal, talent sourcing and invitations, a job board for one-time jobs and ongoing subcontract work, a portable public verified profile searchable by homeowners and businesses, "Lynks" (monitored, document-sharing connections between vetted parties), and reporting dashboards showing compliance counts, contractor maps and trends. Sublynk positions the product as a replacement for a stack of separate tools contractors and networks otherwise use: a lead platform, a certificate-of-insurance checker, a background check vendor, a job board and spreadsheets. The company says it is SOC 2 Type II compliant. Trades represented on the platform include restoration, water and fire mitigation, roofing, drywall, HVAC and contents.

Founding story

The founders framed the company around a recurring problem in the trades: a contractor repeatedly proves the same credentials, and a network spends months and extensive paperwork confirming them. Sublynk was built so that verification happens once, at the source, and the resulting proof travels with the contractor to every new relationship.

Business model

Sublynk sells software and verification services around a two-sided network. Contractor networks and businesses that manage contractor rosters use the platform free — including verified onboarding, live compliance tracking and real-time credential monitoring — while contractors pay a flat subscription for vetting, a verified public profile, job access and B2B connections. The company explicitly does not charge lead fees, commissions, or a percentage of job value.

Flat monthly subscription paid by contractors, stated at $25 per month, with the network/business side free; no lead fees, commissions, or revenue share on jobs.

Traction

Publicly disclosed traction is limited. The company reports partnerships and program-specific onboarding requirements with TPA and franchise networks (including Accuserve and Altimeter) in its knowledge base, and announced a seed financing in 2025 that it said would fund platform capability expansion and market reach. Third-party listings describe the company as seed stage with 2-10 employees.

Latest developments

In 2025 Sublynk announced a seed financing of approximately $3.07M, reported as intended for platform development, additional features and market expansion; a third-party funding database lists FJ Labs among its investors. The company also publishes partner-specific onboarding and compliance documentation for TPA and franchise networks, including an Altimeter partnership and Accuserve onboarding, background-check and insurance requirements.
