1. People build software differently now. There's not as much reliance on text messages (fewer phone apps build built, 2fa via phone is considered dangerous, etc)

2. Gig economy is stabilizing. There was a huge increase in new companies for years, but at this point it feels like we've stalled on new innovations in that space (while a lot of VC-subsidized ones have faded out)

3. There's way more regulations on spam (good for us, bad for Twilio). I think Twilio did as good a job of avoiding spam as anyone could reasonably expect, but the barrier to entry to using Twilio for even reasonable projects now involves the government. Plus with the crackdown on spam (good!), a portion of their business has likely been affected.
