Our approach

Tools that tell you the truth.

  1. 01

    No invented benchmarks

    Where we describe what a number means, we call it a rule of thumb and say how much it varies. Your own trend is the comparison that matters.

  2. 02

    Assumptions on the page

    Every projection and estimate lists its assumptions under “How this works”, so you can judge the result for yourself.

  3. 03

    Content first

    A boost can add social proof to a launch. It doesn't replace a clear profile, good posts and a reason to follow, which is what most of these tools help with.
