Twilio is a great platform, but it's still yet another cash burning technology company with a long way to go on being FCF positive. I've certainly seen worse balance sheets, but they have funds and may be able to make it work out over a longer time frame. Last month was one heck of a month for the stock and it's arguably in bubble territory along with many other PaaS organizations.
It's going to take some time for this one to play out, but a rally month in May could lead to a basing month in June and then depending on market sentiment a drop in July. No position yet, best thing to do for now is set some alerts for price movement and see how it plays out.
