Documented cause
TestFairy, an Israeli mobile app testing and distribution platform, was shut down by Saucelabs in January 2023, roughly two years after being acquired. TestFairy had raised under $5M and was bought by Saucelabs in 2021 to bolster mobile testing. Saucelabs itself faced financial pressure after its 2019 $88M funding round failed to generate sufficient returns, and the company underwent significant restructuring in 2022, cutting costs by retiring acquired products including TestFairy.
Lesson
“Being acquired doesn't guarantee survival — acquirer financial health is an existential dependency.”
