In late April, when Mike Massaro set out to get $40 million to $75 million in funding for his payments start-up, Flywire, he contacted a small group of investors he already knew. But word quickly got around, and other investors flooded his inbox with $200 million of investment offers, half of which he turned down.
Gusto, a payroll and benefits software company, raised $140 million in July, but could have done five times that, according to Joshua Reeves, its chief executive and founder.
