The alternative is launching too soon, getting it wrong, and being accused of killing everything.

Not when it's a legal feature designed for enterprises.

A partner company willing to test it is going to take 3 months to review and choose to adopt it, another 3 months trying to convert a few internal flows, and another 6 months to observe how it changes processes and whether it's an improvement or not.

The point here is to get it right, not to get it quick. Enterprise software is the literal opposite of "move fast and break things".

14 months in testing, 0 support of eIDAS, the main electronic signature regulation and platform in Europe.

This is normal for Google, especially when some legal matters are involved.

This is an intentionally crippled product. Google can't afford to give regulators a reason to go after them for a couple billion dollars. Google or Microsoft could easily have created a DocuSign competitor and killed DocuSign, like they killed netscape, wordperfect, etc. Now that they respectively control the internet and the enterprise software suite, they have one primary goal: protect and grow the cash cow. Everything else is a marketing exercise or a concessionary project given to keep busy the tens of thousands of computer scientists that they are paying to keep out of competitors/startups payrolls.

What's the rush for this?
