Most people go to SF for the weekend and hit Dolores Park.
We went and built an AI that might save you $15,000.
Four builders. Six hours. One hackathon. PMs in AI.
Let’s go.
The backstory
I’m actually thinking about moving to SF.
So like any normal person I started apartment hunting.
Found a place. $3,150/mo. Beautiful photos. Great vibes. I’m in.
Then I looked closer.
- $275 — parking (nearest garage)
- $140 — utilities
- $35 — trash fee (buried in clause 14.3, lol)
- $45 — pest control (mandatory)
- $15 — package locker (can’t opt out)
Real rent: $3,660.
That’s $6,120 a year nobody told me about.
That’s a round trip to Tokyo I’ll never take.
Cool.
But it gets better.
The gym I picked the whole neighborhood for? 25 min by transit. I’d quit by month two and we both know it.
Management company runs 14 buildings — tenants in 9 of them say repairs take 3 weeks.
Block gets loud Thursday through Saturday.
I’m a light sleeper.
Awesome.
Here’s the wild part
All of this info is public.
Building violations. Noise complaints. Tenant reviews on Reddit and Google.
It’s just scattered across 10+ sources nobody has time to check.
So you sign the lease.
Cross your fingers.
Find out the hard way.
The hard way costs $15,050.
(Early termination + forfeited deposit + new deposit + movers + overlap rent. Fun.)
What we built
So this weekend we said screw it, let’s build the thing that should already exist.
We built Nyx. Know the city before it knows you.
Paste a listing. 60 seconds. Nyx pulls violations, block-level noise data, management reviews across their whole portfolio, hidden fees, parking, amenities matched to YOUR life.
No dashboard. No scores. It just talks to you like a friend who’s lived in SF for 10 years and won’t let you sign a bad lease.
It walks you through your actual Wednesday — gym, commute, coffee, when the block gets loud, what dinner looks like.
A movie of your life there. Not a spreadsheet.
Then one call:
→ Go — move fast.
→ Negotiate — here’s your leverage.
→ Walk away — here’s why.
People make $40K decisions on listing photos and vibes.
We built the antidote to vibes.
In six hours.
On a Saturday.
If you’ve ever moved somewhere and thought “why did nobody tell me” — comment below. We’ll send you the MVP.
