About

What is Signals

Signals builds a live graph of your professional network by indexing relationship history across emails, meetings, and interactions, then lets you query it in plain language to find the warmest path to any contact. It's built for founders, SDRs, BDRs, and AEs at solo operations through mid-market teams who need to move faster on deals without starting cold. The standout capability is its "Cloud Employees" — AI agents that handle customer conversations across phone, email, chat, and SMS without human hand-holding on every exchange. It can also reach beyond your existing network by searching 800 million profiles when your graph runs dry. Where it starts to strain is depth of CRM-native workflow: teams that live inside Salesforce or HubSpot and need tight two-way sync may find the integration story thinner than dedicated sales engagement platforms.

Our verdict

Vanderbuild take

Signals sits at an interesting intersection of relationship intelligence and AI sales assistant — it's less a traditional SDR tool and more a graph-powered layer that tells founders and AEs who to call, how to get there, and then hands the conversation to an AI agent to run. The REST API is live and documented, so you can wrap Signals into your own MCP orchestration layer without much friction — solid agentic readiness for teams building custom outbound stacks. Pricing is undisclosed publicly, which makes budgeting a conversation rather than a calculation — factor in discovery time before committing. The honest limitation here is CRM depth: if your team's source of truth is Salesforce or HubSpot and you need bidirectional sync with full activity logging, Signals may require supplemental tooling to close that gap.
