How does a company make money from a reverse-takeover?

I am trying to understand the following news article:

So my (potentially-flawed?) understanding of a normal public offering is that the owners of a company receive money from the underwriters (like Goldman Sachs) of the offering who then in-turn sell the shares to public.

In the case of Keek, the company purchased an already-publicly-traded company (in a bizarre unrelated business) for the purpose of being listed publicly. But how to the owners of the shares of Keek benefit from being listed publicly now? If I buy a share of the company does that somehow go directly to them?

Merging with an already-listed company saves them the trouble of going through the whole lengthy IPO process. Instead, they can use the existing company to do secondary share offerings directly to the public market, when they feel it is necessary.

I was peripherally involved in a reverse take-over way back in the 70s (in the UK)

The company I worked for (now extinct) was ‘taken over’ by a much smaller company in the same line of business that was already listed. This was a cost effective method of getting the whole business to the Stock Exchange.

A search revealed this:
