Stairoids is a real-time, signal-based go-to-market platform built for B2B agencies and revenue teams. It listens to every meaningful engagement event across your marketing and sales tools — website visits, email opens, CRM stage changes, LinkedIn interactions — and unifies them into a single, scored view of every account and contact. From there, Stairoids lets you automate exactly what happens next: enrich a record, enroll a contact in a sequence, alert a rep, or update a deal. Instead of chasing disconnected data across a dozen tabs, you get one intelligent layer that connects your entire GTM stack and acts on it automatically. ## Who Stairoids Is For Stairoids is designed for the people who build and operate revenue infrastructure: * **RevOps teams** who need a central place to correlate signals and enforce consistent, automated workflows across the funnel. * **Marketing operations teams** who want to trigger sequences or enrichment tasks the moment a prospect shows intent. * **B2B agencies** managing GTM programs for multiple clients, using Workspaces to keep each client's data and automations fully isolated. ## Key Concepts Before diving into the platform, it helps to understand the four building blocks that everything else is built on. | Concept | What it is | | ------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Signals** | Discrete engagement events captured from any connected tool or sent directly via API. Every signal carries a type, an account, an optional contact, and custom properties. | | **Signal Intelligence** | The scoring and correlation engine that combines signals across sources to produce a unified engagement score for each account and contact. | | **Incoming Automations** | The mechanisms through which signals enter Stairoids — native integrations, inbound webhooks, or direct API calls. | | **Outgoing Automations** | Rules that fire when signal thresholds or conditions are met, pushing actions back to your connected tools. | ## What You Can Build Stairoids is flexible enough to power a wide range of GTM workflows. Here are a few examples to spark ideas: * **Intent-triggered outreach** — Auto-enroll a contact in a HeyReach LinkedIn sequence the moment they visit your pricing page. * **Deal-stage enrichment** — Automatically enrich a HubSpot contact with firmographic data when their deal advances to a specific stage. * **Account surge alerts** — Notify a Slack channel when an account's engagement score crosses a threshold, signaling buying intent. * **CRM hygiene automation** — Update a contact's lifecycle stage in your CRM whenever a qualifying signal cluster is detected. * **Multi-client signal routing** — Use Workspaces to fan signals from shared integrations out to the correct client workspace automatically. ## Explore the Docs Send your first signal and see it scored in under 10 minutes.
