B2B companies
Dell, IBM, Microsoft and Oracle among them. Most of the rest you have not heard of yet.
The platform
One engine. Two layers.
You cannot send an email without mailboxes, or a LinkedIn message without an account. Most vendors rent both and lose them when the rules change. Vendisys owns that layer, every agent runs on it, and every product writes to HubSpot or Salesforce and ships with an MCP server.

How it works
One lead, start to finish.
From a competitor's handshake to a meeting on your calendar.
- 1
Step 1 of 4
A buyer moves. CAM hears it.
A connection with a competitor's rep, a new competitor follower, a job change, engagement on a post, a mention. CAM is the signal layer. It scores the moment and emits the event.

Step 2 of 4
Scrubby verifies before anything is sent.
Every address is cleared, including catch-all. Nothing reaches an inbox that could damage reputation, and the record is already in your CRM.
- 3
Step 3 of 4
Agents make the touch, on infrastructure we own.
KALI places a calendar invite. LIA works LinkedIn through an AIA identity. EMY sends the sequence through Inboxy mailboxes. Nobody rents a channel.
- 4
Step 4 of 4
Underfive unifies the replies, books, and writes it back.
Email and LinkedIn replies land in one inbox, get classified and answered in your voice. The meeting is booked and HubSpot or Salesforce is updated. No human carried anything between steps.

From the founder

Platform
Run the engine with your team.
Sign up for any product on its own. Each one works alone, and each one gets better the moment it is connected to the infrastructure layer.
Managed programs
Or have Vendisys run it for you.
The team that built the engine operates it for enterprise programs: targeting, copy, infrastructure, replies, and a meeting volume we commit to. This is how we booked the first 100,000.

Suppression List Management for Cold Outbound: Build a Do-Not-Contact Layer That Protects Pipeline
Most outbound teams treat suppression as an unsubscribe checkbox. It is actually the layer that stops you from emailing customers, open deals, competitors, and people who already said no. Here is how to build and maintain a real do-not-contact system.

Clay vs Outsourced Outbound: When to Build Your Pipeline Engine and When to Buy One Done-For-You
Clay gives you a powerful canvas to build an outbound engine yourself. An outsourced partner hands you the finished engine and runs it. This is how to decide which one your team actually needs, based on the resources you have and the pipeline you are trying to hit.
