San Sasakay is a crowdsourced transit platform for Metro Manila's informal network — jeepneys, UV Express, buses, tricycles, and ferries. Commuters share what they see at the stop; everyone else gets a live answer before they leave.

“Makakauwi ka ba?”
I wasn't trying to solve a transit problem. I was just trying to get home.
A few friends and I were out one night, and when it was time to leave, nobody knew what route to take. Which jeep goes where. Is the UV still running this late. We were just standing there, guessing — the way every Filipino commuter has guessed, every single day, for decades.
Then my friend, we will call her Ugah, turned to me and asked: “Makakauwi ka ba?”
That question stayed with me. Not because it was dramatic. Because it was so ordinary. Millions of people ask some version of that question every day — before they leave the office, before they step out of a mall, before they decide whether to spend ₱300 on Grab or take their chances on a jeep that may or may not come.
And the answer is always a guess.
There's no app for that. Not really. Google Maps doesn't know if Route 22 is running tonight. Waze is for people with cars. Nobody built anything for the commuter standing at the corner of Market! Market! at 10pm, just trying to get home.
That's what I'm building. Not for the commuter who can afford to book a ride every time. For Ugah. For everyone who's ever stood at a stop and just… waited and hoped.
Two founders — systems and craft — shipping San Sasakay for the commuters who still guess whether they can get home tonight.
