Hi, I'm Zanwen
I buy stocks, but I don't have time to follow the news every day.
Last year I spotted a company early, then missed its IPO. This year bad news hit it. I missed that too, and didn't sell in time.
So I built Tellwhen. Tell it what matters to you, and you won't miss it again.
Before this: VYNN AI, Robinhood, AutoCodeRover (acquired by Sonar) and Binance.
What are you waiting for?
Email Tellwhen today and never FOMO again.
