These days, every billboard and bus shelter in San Francisco seems to be advertising some kind of indecipherable AI startup. “Why buy billboards in SF when you can just send me swag to market your startup?” Kothari wrote on X shortly before dinner on Labor Day. Kothari’s marketing deal: He wears the company T-shirt or hat sent to him, and he walks the city. They include pre-seed startups, startups in India (where Kothari is from) and public companies like Figma (valued at more than $20 billion). “Every new company gets to know about all the older companies,” said Snehil Saluja, co-founder of Overlayy AI.
