Verbiflow

Verbiflow provides sequencing infrastructure for growth teams to run multi-channel outbound (email, LinkedIn, and early access cold calls) from a single platform. It emphasizes deliverability, a shared inbox, and operability from AI agents to build and execute outbound plays.

Verbiflow centers outbound sequencing by allowing users to source audiences, create multi-step plays across email and LinkedIn, provision and warm mailboxes, monitor deliverability with inbox-placement checks, and maintain a shared inbox for replies. It supports running sequences from popular agents (Claude, Cursor, Codex) via an MCP, integrates with CRM sync, and enables grooming lists from various data sources (CSV, HubSpot, Attio, LinkedIn, job posts, etc.). It offers starter sequences, paid plans, and a pricing model based on monthly credits and seats, with cold calling in early access.

Who it’s for: Growth teams and startups looking to scale outbound sequences across email, LinkedIn, and calls, with emphasis on deliverability and cross-team alignment.

Established product with public pricing, mentions of backing by Y Combinator (Combinator), and ongoing rollout of cold calling feature (early access).
