CTO of Modern Treasury here. We're very happy with the quality of the client libraries being generated by Stainless. It also integrates nicely into our workflow, we've got the releases almost fully automated whenever new API routes are added or changed.

Big fans of Vanta over here. Compared to everything else in the market, they were clearly the furthest ahead for our SOC2 needs.

I'm sure everyone's setup is different but I did this for about 8 years and had to stop recently due to a variety of problems. The first being the lack of support for group messaging. I couldn't send group messages at all but what was even worse was that when I was part of group messages I would receive the messages individually as if the person was texting me directly. My system could mark them as being group messages but I couldn't see the other recipients so there was no way of knowing who else was in a thread until other people started texting and then could piece together the group from context.

Also some services straight up refuse to send SMS to cloud phone providers meaning you can't sign up for certain services that needed a verified phone number (unless they had an option to receive a call with the verification code which worked like 25% of the time).

Dialing was another huge issue, you can somewhat intercept outbound calls on Android but the system is buggy so I had to find other methods. Since I had integrated my SMS/MMS messaging with Slack (one slack channel per phone number) I created a /dial command that would call my phone and then when I answered it would transfer me to the person I wanted to call.

Happy to answer more questions about it but I highly recommend people think about all the consequences before moving their main number over.

On the consumer banking side I would agree with you, not many individuals have complex enough banking needs where programmatic access would be a value-add. However if you look at businesses, any company doing more than (let's say) 50 bank-to-bank payments a month I think would benefit from being able to automate their bank account interactions in some fashion.

We've heard (unofficially) the cap will be raised over time.
