    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.

      Signals are checked daily, so you are working a list of people who moved this week, not last quarter.

    Sales teams love Sendio.

    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.

    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.
