Stripe CEO Patrick Collison announced his engagement on Sunday, and he did it with a geeky industry tweet. 

"We hit our engagement metrics this weekend!" Collison wrote, alongside a photo of him and his fiancée. 

The joke is particularly fitting for the head of Silicon Valley-based private tech company Stripe, an online payment platform valued at $22.5 billion.

Collison's brother, Stripe cofounder John Collison, commented "Oof, ratioed" on Sunday, poking fun at the success of his brother's metrics claim. 

Fellow Silicon Valley tech execs chimed in with on-theme congratulations. Mixpanel founder Suhail Doshi commented "That's one way to increase user retention." 

Box CEO Aaron Levie asked, "How much testing did you do on the invite flow?"

Patrick Collision, who keeps his personal life private from social media, did not post his fiancée's name with the announcement.

Irish brothers Patrick Collison and John Collison founded Stripe in 2010. Forbes listed John Collison as one of the world's eight under-30 billionaires in March 2019, and as one of only three self-made billionaires on that list.
