How we operate

No channel conflict

We sell the platform to MSPs, UCaaS providers, integrators, and resellers. We don’t sell communications services to their customers or compete for those relationships.

Platform-first

We build a single, multi-tenant platform — not an acquired stack of pieces. One system, one upgrade path, one support contract.

Brand the service

In-Product Branding applies each tenant’s logo and brand colors in supported platform and Connect app surfaces. Expanded mobile branding is available separately.

Open and integrable

Documented APIs, AMI/AGI, integration webhooks, and local lifecycle event hooks connect Thirdlane with the systems you operate.

Long-term thinking

Two decades of communications platform engineering. Predictable roadmap, predictable economics.

Our footprint

Thirdlane runs in production across the Americas, Europe, the Middle East, Africa, and Asia-Pacific — deployed by service providers and enterprises in dozens of countries.

A note from the founder

“Our partners and customers asked us for a ‘magic’ combination of advanced features, high-availability, depth of customization, and ease of use. It wasn’t magic; it was hard work. We pulled it off.”
— Alex Epshteyn, Founder, Thirdlane

Twenty years on, the answer to “why Thirdlane?” is the same. A single multi-tenant platform. Open architecture. A partner channel that owns the customer relationship. No surprise re-licensing when the next major version ships.
