I didn't count Parakey because they were not a regular YC investment. We didn't seed fund them. We were just one of many investors in their series A round.
We usually wouldn't invest that late, but Blake and Joe were so good that it was hard to resist.
Wasn't there some article somewhere that mentioned a rumor about textpayme getting bought by amazon?
I haven't heard that, but it would make sense, considering Amazon's release of the Flexible Payment Service.
No, Parakey is public knowledge. And the reference to "one we can't talk about" first appeared in "Why to Not Not Start a Startup" (http://www.paulgraham.com/notnot.html), which was written before Parakey was acquired.
The impression I got when pg gave the talk at Startup School was that it was some kind of "big company buys little company because they were scared of what they were making" situation. But as far as I know that's all they can say.
PG: Will there be a point when you can talk about the other one that got acquired or is it going to be permanently off limits, at least for the foreseeable future?
They keep telling us we'll be able to talk about it soon, but they've been saying that for a while. It was actually the first acquisition, many months before reddit.
