Launch YC: Lucent - AI that automatically watches your session replays

"See every bug your users experience"

Founded by Alisa Rae

She previously bootstrapped and sold an Australian EdTech startup, and before then she was employee #2 at MagicBrief (acq. by Canva). She has always been obsessed with session replays, they’re incredibly valuable. But the data just goes to waste because no one has time to watch them. She has wanted something like Lucent to exist for a long time, and she is grateful to have the opportunity to finally build this.

The problem:

  • You are collecting a lot of session replays but no one has time to watch them
  • Users are silently hitting bugs in your product, and most of them don’t report bugs, they just churn

The solution:

Lucent is an AI that watches your session replays 24/7, and automatically detects issues your users are running into in real time

How it works:

  1. Connect your PostHog account
  2. AI watches session replays 24/7
  3. Bugs get sent to your Slack or Linear as users encounter them

How to get started:

If you’d like to try it out, you can get 400 sessions processed for free and see what issues your users are coming across - most teams find issues in the first hour they didn't know existed. They have already used by 30+ YC companies, including Reducto (W24), Julius (S22), Finta (W23), and Happenstance (W24).
