Stated investment criteria

What Boston Harbor Angels says it buys

Read from Boston Harbor Angels’s own website in August 2026. This is what the firm says it buys, not what anyone has recorded it buying, and figures are shown in the currency the firm itself used - nothing here is converted. Every line links to the page it was read from.

Minimum revenue it states$50m1
Maximum EBITDA it states$5m1

A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. Nothing here is a commitment by Boston Harbor Angels to consider any particular business, and nothing on this page is represented as being for sale.
