How we operate

Channel-only

We sell exclusively through partners — MSPs, UCaaS providers, integrators, and resellers. We don’t compete with our channel for end-customer revenue.

Platform-first

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

White-label deeply

Our partners’ customers should see their brand, not ours. Per-tenant branding goes all the way to the apps and admin console.

Open and integrable

Documented APIs and webhooks for everything that matters. Your engineers should never be blocked.

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 reseller channel that owns the customer relationship. No surprise re-licensing when the next major version ships.
