The hardest part of building an AI matchmaker wasn’t the model

The hardest part of building an AI matchmaker wasn’t the model.

It was deciding what not to optimize.

From an engineering perspective, it’s very easy to make a dating product look “alive”:
more swipes, more matches, more notifications.

The harder problem was building systems that could:
– tolerate silence
– slow down recommendations
– and still be confident in a match

We spent a surprising amount of time designing memory and decay:
what the system should remember about a person,
what it should forget,
and when it should wait instead of acting.

Astute Kitty doesn’t just score compatibility —
it reasons about timing, emotional readiness, and communication rhythm.

Loving Kitty exists for a simple technical reason:
emotional context doesn’t fit neatly into state machines.

Building this forced us to treat users less like traffic
and more like long-running processes with history.

It’s slower.
It’s less “impressive” in dashboards.
But it feels more honest.

LoveActually wasn’t built to feel busy.
It was built to feel calm.
