What do service providers need to compete and grow?
True multi-tenancy, complete brand ownership, zero channel conflict, a complete unified stack with AI and integrations, flexible deployment, and economics that scale — among other factors.
True Multi-Tenancy
One platform serving many isolated tenants — not one instance per customer. Tenant isolation, per-tenant billing data, role-based admin.

Frequently asked questions
What is Thirdlane?
Thirdlane is a white-label, multi-tenant communications platform that MSPs and service providers use to deliver voice, messaging, and omnichannel interactions under their own brand. It combines business voice and Connect apps with powerful built-in modules for contact center, CRM, and AI — all in one system that you can self-host or have Thirdlane operate for you.
Who is Thirdlane for?
Primarily MSPs, ITSPs, telcos, and UCaaS providers hosting communications for their own customers. It also serves enterprise IT teams running multi-site setups for a single organization through an authorized partner or integrator.
How can Thirdlane be deployed?
Providers can self-host the multi-tenant platform on their own infrastructure or have Thirdlane operate it under the provider’s brand. MSPs and integrators can also deploy a dedicated environment for single-customer requirements.
Is Thirdlane white-label?
Yes. Provider and tenant logos, names, and custom colors can be applied across platform interfaces and Connect apps. Custom mobile application artifacts and app store-publishing assistance are also available.
Who owns the customer relationship?
You do. Branding, pricing, billing, and the direct relationship with end customers always stay with the service provider — whether you self-host or use managed infrastructure. Thirdlane never competes with you or sells communications services to your customers.
