What Sillage does.

  • Find in-market accounts

    Sillage scans the market for accounts that match your ICP and show buying intent right now. You get a feed of new accounts with the signal, the person behind it, and the reason it matters. Teams build pipeline without buying static lead lists.

  • Account monitoring

    Upload or sync a list of key accounts, prospects or customers, and Sillage watches them for you. It flags champion moves, new decision makers, competitor engagement and growth events. Sales teams act at the right time, and customer teams spot churn risk and upsell moments early.

  • Account mapping

    Sillage maps the people inside each account by department and seniority. You see who the decision makers are and who is missing from your CRM. Reps walk into every deal knowing the buying committee.

  • Signal data for GTM agents

    Sillage is built as a data layer. Signals flow into your CRM, your workflows and your AI agents through our MCP server and integrations. Your outbound agents work on fresh, verified context instead of guesses.

  • Signal data for GTM platforms and agencies

    GTM platforms and agencies can plug Sillage signals into their own product or run separate signal watches for each client. Each client gets its own personas, lists and agents, so partners offer signal intelligence without building it.

What makes Sillage different.

  1. 01

    Built for agents, not only dashboards

    Sillage delivers signals through an MCP server, so AI agents can query and act on them directly. Tools like 6sense and Bombora were designed around dashboards and ad audiences for human users. With Sillage, the data goes straight into the agents and workflows that run your outbound.

  2. 02

    People-level signals, not just company intent

    Sillage tracks 11 live signal types across 4 categories, including champion moves, job changes and engagement with competitors. Bombora mostly provides topic-level intent scores at the company level. Sillage tells you which person did what, so your message has a real reason to exist.

  3. 03

    Priced on what you monitor, with a free trial

    Start with a 14 day free trial, no card required, then pick a credit-based plan. Monitored accounts refresh weekly by default. 6sense is usually sold through annual enterprise contracts.

  4. 04

    European data, hosted in the EU

    Sillage is a Paris based company and our app and database are hosted in the EU. Emails and phone numbers are fetched only when you ask for them and are not stored in our dataset. Teams with GDPR requirements can buy signal data without a long legal review.

  5. 05

    An alternative to Trigify

    Trigify was acquired by HubSpot in 2026 and its product is being retired. Sillage covers the same social signals and adds account mapping, account monitoring and agent delivery. Teams moving off Trigify can keep their signal workflows and get more coverage.

The team behind Sillage.

Sillage launched in September 2025. The founders had spent years watching sales teams buy intent data they could not act on, so they built a signal product that sends the data where work actually happens.

How Sillage works.

  1. Step 01

    Onboarding

    You create a workspace, connect your CRM and define your ICP and personas. Then you create lists of prospects or customers and choose which signals to watch on each one.

  2. Step 02

    Who you work with

    A customer success manager helps you set up your first signal watches and lists. On larger accounts, a Sillage engineer works with your RevOps team to plug signals into your CRM and agents.

  3. Step 03

    Support

    You can reach us through in-app chat and by email. Your reps never need to live in Sillage: the signals come to them.

  4. Step 04

    Signal delivery

    Monitored accounts refresh weekly by default, and you can ask for daily or monthly refresh. Signals are delivered in the Sillage app, in your CRM, and to your agents through MCP.
