Key Takeaway 1

Something happened this week that I cannot stop thinking about, and it is not from a car company. It is from Korea. A car wash app — Sejinsa, spelled S-E-J-I-N-S-A — just raised bridge funding, got picked for a Korean government tech program called TIPS, and here is their plan. They already come to your parking spot and wash your car. Sixty thousand washes so far. Four thousand crews. And now they do engine oil and tire replacement too. And here is the part that got me. Their crews photograph your car at every single wash, and they are training artificial intelligence to read those photos — exterior damage, engine oil condition, battery health, tire condition. So the wash visit becomes the inspection. They know your car needs an oil change before you do. Look… that is the play. That is the...

Key Takeaway 2

Okay but why is nobody talking about the business model math here? Car washing is the most frequent thing a car owner pays somebody else to do. That is their founder's entire argument — the wash is the trojan horse. You wash a car six, eight times a year, you get six or eight looks at that vehicle. Six or eight photo sets of the same car, building a history. Nobody else in the service chain sees that car that often — not the dealer, not the lube shop, not the tire store. So Sejinsa is not building a wash company. They are building a data collection company that happens to wash cars, and the oil change is just what they sell once the data says it is time. That would absolutely eat on TikTok, by the way — imagine the content: "we flagged your tire wear three visits before you noticed."

Key Takeaway 3

I do not know yet, let us figure it out — does the photo thing actually work? A wash crew is not a technician. You are telling me a twenty-year-old with a pressure washer is going to judge my engine oil condition from a photo? I have been wrong about tech before, but here is the thing… even if the artificial intelligence is only right half the time, it still changes the game. Because now the upsell comes with a photo. "Look at this." That is a hundred times more powerful than my tech saying "your oil looks dark." I do not love it, but I respect the mechanism.
