We charge for the impact that we make to your team, which in our case is reducing your test time. In our opinion, typical pricing metrics like # of developers or total # of tests are not customer friendly. We wanted something more customer friendly and in line with our company value to make customers our fans.
How do you calculate hours saved?
First, some context: every time you request a subset of tests to run, you send Launchable your full list of tests in your test suite along with an optimization target. Launchable returns a subset of the full list you sent based on that optimization target.
Therefore, we calculate hours saved by taking the difference between the typical duration of the full list of tests (based on historical data) and the duration of the subset of tests from Launchable.
For example, if your test suite typically takes 4 hours to run, and a Launchable subset that yields 90% confidence only takes 1.5 hours, then your hours saved for that run will be 2.5 hours.
What's my return on investment?
Your ROI on Launchable is three fold: increased velocity, time saved for developers and time saved in machine resources
Faster tests and faster feedback = Increased Software Delivery Velocity
Developers are the highest paid resources on a team. An hour saved with Launchable on a test run saves time for multiple developers on the team.
Hours saved on test runs usually means that hardware resources can be deployed elsewhere
We typically see customers making back their investments with developer hours saved in weeks.
