Amplitude and Statsig, previously competitors, announced a partnership in May 2026 where Amplitude will manage the Statsig brand and customer base. This arrangement follows OpenAI's $1.1 billion acquisition of Statsig last year, with the original Statsig team remaining at OpenAI. As a result, Amplitude inherits the platform's code and customer relationships while handling its roadmap and support, potentially affecting customers who valued Statsig's rapid innovation.
