All of it gone.
Boston sells itself as a city that builds companies. This page is the other ledger: 221 startups that took money from investors, employed real people, published launch-day press releases, and have since ceased operations.
The figures below are drawn from the public record of those companies. They are presented without commentary, because they do not need any.
—most expensive sector
—largest single failure
—had “AI” in the pitch
—amounts never disclosed
Where the money died
What failure cost
Amount raised before closing. Twenty-four of these companies raised nine figures first. Raising money is not a business model.
When they closed
Close dates survived for only 26 of the 221. The other 195 took their dates with them.
