Mainlane for service-SMB software sellers

AI outbound built on real local-business proof.

Mainlane sources local service businesses, builds a structured lead profile, extracts grounded proof from websites and reviews, and turns that into outbound drafts your sales team can actually use. The current live demo is seeded around a RepairDesk project inside the product.

What the core engine writes

The product does not draft from vague segmentation labels. It drafts from profile context and extracted proof that can be traced back to source text.
