The challenge

GTM shouldn’t be this hard.

Even a simple growth idea can turn into a full-time job.

  • Choosing the right play to build is hard.

  • Getting the tools to work together is hard.

  • Turning results into next steps is hard.

Add-on modules

From first signal to follow-up.

Pick only the ones you need. Add more, and their impact compounds.

Listening

Hear the conversation. Jump right in.

Track keywords and competitors, reply on the spot, and turn everyone who engaged into a list for Campaign.

Campaign

Don't wait for the conversation. Start it.

Set the campaign's goal, then get a sequence written for each person from what you've researched about them.

Content

Show up consistently. Let buyers come to you.

Turn meeting notes, new features, or a quick thought into founder-led posts, in your voice.

ConversationsComing soon

Every conversation keeps moving.

Whatever the channel, every conversation updates the record. AI replies and follows up, and loops you in when it should.

Core modules

The context behind every action.

Bring your team's knowledge and market feedback together, so every action builds on what you've learned.

Record

Customer history, always at hand.

Keep research, conversations, and deal progress in one record, so every interaction starts with context.

List

Your audience, organized.

Segment people or companies for campaigns, listening, or follow-up. Reuse the audience across your work.

Sheet

Raw data, safely explored.

Organize, enrich, and test ideas in a temporary workspace. Your records stay untouched.

Workflow

Next steps, automated.

Hand off repeat work. Each new signal updates your data, alerts the owner, or puts an agent on it.

FAQs

An AI workspace for founders and lean growth teams to discover market signals, research prospects, run campaigns and publish content. Keep your team’s research, audience records and workflows together so each play builds on the context you already have.

Start with Listening, Campaign or Content, or use Core alone. Every plan includes Sheets, Records, Lists and Workflows. Combine modules when a play uses more than one. Conversations, including Inbox, Meetings and Autopilot, is coming soon and is not on sale.

Listening can collect supported public conversations from Threads, LinkedIn, X and Reddit. Collection and replying have different limits: Threads and LinkedIn replies require a connected identity and permission for the target. Cold replies on X are unsupported; Reddit native replies remain partially supported. Review the platform and account requirements before enabling a reply strategy.

Yes. Connect supported agents such as Claude Code or Codex through SignalSurf’s MCP server. They use your workspace context and permissions. Some setup and approval steps stay in the workspace.

Not by default. You review content before publishing and Listening replies before sending. Automatic replies require you to enable auto-send for a specific reply strategy. Agent actions follow the same permissions and approval requirements.

Yes. Use SignalSurf alongside your existing CRM and tools to research audiences, run plays, and keep the context behind your work together. You don’t need to replace your current setup to get started.

Yes. We can help you choose a first play, set up the workspace, and get it running. We’ll agree on the scope, responsibilities, review cadence, and usage budget together.

You have the idea. We make it real.

From the first signal to the follow-up, we’ll build the play with you.
