I'm Sinay. I build small companies end to end: the product, the story, and the numbers behind it. Most mornings start in the water.
I studied mechanical engineering, fell into online marketing, and taught myself to code so I could build the things I kept pitching.
For fourteen years I've grown other people's products: at Google, twice; at Taboola; at Lili, where we went from nothing to 100,000 users in six months; and now as VP Marketing at Greetings Island, past ten million app installs.
Alongside that I build my own: small, useful tools that make one decision easier. A few of them ended up on TV and in the papers.
