No way am I giving your startup* my phone number. Maybe you can have a custom-generated, one-use-only email address that I can turn off so you don't spam me. (Your startup may be virtuous, but most startups fail, and then my data becomes an asset that gets sold away in bankruptcy.)

I also hope that your startup has been advised on the very significant TCPA liabilities this approach risks. Even if you do everything right, you're going to face lawsuits saying you don't. I have very mixed feelings about the TCPA, and it does hamper "innovation" in some circumstances, but I am delighted that it carries significant litigation risk for anyone who thinks it's a good idea to send me SMS messages. I. Don't. Want. Them.

Actually "single use phone numbers" is a service we've considered building for consumers.
