No. They mostly broker transactions of people whose businesses resemble "A website with X0k monthly uniques acquired through organic SEO which is presently monetized by reviews of various products on Amazon which get the Amazon affiliate program if someone buys that or any other product consequent to clicking their link; revenues for the last 6 months averaged $1,700 on expenses of $300, dominated by outsourced content writing." (That's a point along the spectrum, probably close to their modal listing in sophistication and possibly under their median; I don't follow closely enough to have a great sense of that.)

Some people have businesses like this which for whatever reason they want to sell; other people have money which for whatever reason they prefer less than having business like this [+]. Empire Flippers operates a brokerage which matches these people together, for a cut of the transactional price.

(I listen to their podcast, which is really good, even if one's business does not resemble the above.)

[+] One of the most interesting recurring themes on their podcast is a series of user avatars for who would be interested in this -- Porfolio Paul (wants to have 10+ businesses like this and operate them like someone operates a number of fast-food franchises) and Lifestyle Larry (wants to be the owner of a business which makes $X0k a year in preference to having a day job) are two who stick out for me.
