Smartlead

Smartlead was founded in 2022 by Vaibhav Namburi to build cold-email infrastructure for sales and lead-generation teams that need to scale outbound beyond what platforms like Outreach or Apollo allow. The product supports unlimited mailboxes and warmup credits, multi-inbox campaign rotation, AI-personalized variables, and unified reply handling across email, LinkedIn, and SMS.

The platform targets agencies and B2B sales teams running high-volume outbound, with pricing tiers based on email-sending volume rather than seats. Smartlead claims tens of thousands of customers including agencies and SaaS sales teams.

Smartlead operates as a bootstrapped company with a distributed team.
