Sendio makes it incredibly easy to find thousands of relevant leads for my outreach in just a few minutes, sometimes even seconds. I can create a campaign and let it run for months. That's why I use Sendio almost every day.
300 million contacts. The few that fit you.
Search Sendio's own lead database and narrow it down by lookalike people, lookalike companies, and live buying signals. Then push the list straight into a campaign.
Start from 300 million people, not a blank CSV.
The lead database lives inside Sendio, right next to your campaigns. Search it by job title, seniority, industry, headcount, and location, and watch the list narrow as you go.
- One search, every market
More than 300 million contacts across every industry and country, in a single place.
- Nothing to import
Leads go from search straight into a campaign. No CSV files, no separate data tool, no second bill.
- See the list shrink in real time
Every filter you add updates the match count instantly, so you know exactly how big your audience is before you send anything.
Show Sendio one good customer. Get thousands more.
Point at a person who already converted, or at a company you closed, and Sendio finds the ones that look the same. Role, seniority, industry, size, and background all get matched for you.
- Person lookalike
Pick a buyer that worked and get people with the same role, seniority, and career profile.
- Company lookalike
Pick an account you closed and get companies in the same shape. Same size, same market, same stage.
- Stack them together
Combine both to get the right person at the right kind of company, instead of one or the other.

Sales teams love Sendio.
I've run Sendio across clients in completely different spaces, and it's held up in every one. That's rare. What makes it work is the flexibility in how you build a campaign. The team's genuinely responsive too, the kind of people you want to build alongside.
