About the role

What is Haystack?

Haystack helps build elite developer teams by providing engineering metrics and alerts proven to drive performance, improve software reliability and prevent developer burnout.

Through their integration with GitHub, Haystack is able to provide live data insights that illustrate the entire delivery process from commit to deploy, being able to highlight bottlenecks like code review and team productivity. Using this feedback loop, Haystack users have increased production deployments by 58% and achieved 70% faster cycle times on average.

In less than 12 months since launch, Haystack is being used by more than 7,000 developers at elite developer teams in GoDaddy, Microsoft, The Economist, Indiegogo and Truebill among others as revenues have increased by an average of 36% month on month.

In June 2021, Haystack announced it had secured a US$1.2m funding round after graduating from Y Combinator’s W21 batch.
