They already support over 3.5M users across our customers, with some seeing 3.6x increases in conversion rates after using Polymorph. Users are unique and special, make them feel like it~ The team has extensive experience in the space, having been in senior engineering leadership at Meta Ads, building out large-scale ML infrastructure at Scale AI, and iterating quickly and securely at startups like Gusto, Opal, and Nira.

Personalization infra that improves retention, LTV, and CAC

What is your company going to make? Please describe your product and what it does or will do.

We build personalization infrastructure that lets developers use AI to tailor user experiences and notifications in their apps. Our product simplifies what takes big companies years to build, helping consumer and self-serve apps increase conversion, retention, and lifetime value by making users feel uniquely valued.

Where do you live now, and where would the company be based after YC?

We live in San Francisco and intend to base Polymorph here after YC as well.

Explain your decision regarding location.

San Francisco has the tech talent and startup ecosystem we need. All three founders are already based here, so it makes sense to keep the company in a place where we can easily recruit and operate.
