How it works

Three steps to your
best quarter ever

From prospect to reply in minutes, not days. Here's the workflow that top sales teams use.

Step 01

Describe your prospect

Tell our AI who you're looking for — title, industry, company size. It searches the web and returns enriched profiles.

CTO · AI/ML · Raised $10M+
Step 02

AI writes the email

Each draft references the prospect's recent work, funding, interests. It reads like you spent 20 minutes researching them.

Step 03
