It's interesting, we've talked to a LOT of companies about this as customer research for our SaaS product (https://carrot.io) and 150 is actually where this problem become unbearable. We see this problem first come up consistently at 30 people, become a major problem at ~100 people that starts to get lots of attention inside the company, and becoming a real hindrance and burning issue if not addressed at ~150+.

It's not at all surprising to us that both Stripe and Square have spent a lot of time and money on this problem to support their quick growth past 1,000 people.
