Whisper Systems was founded in 2010 according to Wikipedia, while the funding from the open tech fund started in 2013.
Interestingly, Singnal actually introduced its cryptographic protocol to the public only in 2013, when they got the funding (see even Wikipedia for that).
The app already had E2EE at that point, this only marks the release of the v2 of their protocol, which is now considered state of the art for asynchronous messaging.
