A SPAC is a technical vehicle as an alternative to an IPO for an existing company.
WeSC and Doxa are existing public companies that diversify their business activities..
Apart from having entrepreneurial visions, there is no similarity between the named companies and SPACs. All businesses are built on intentions - not all are as bold as these, perhaps - true!
Mind you, their vision does not come out of the blue. We are dealing with people that have their merrits, involving additional human and financial capital to pursue a new adventure.
A very important matter here is that their ideas are at the base staked by their own capital.
Then they leave it to the free market to value their intentions.
Not all such intentions lead to the same trip to the moon, mind you. A lot of Spacs are being neglected and undervalued, read: unsupported.
By the way:
To owe a stake in a seemingly overvalued company is not per definition a grace. Somebody will need to pay you that value to turn it into cash. And that someone also hopes for a good return by believing in the same intentions.
Nobody forces or fools the buyer in the end... apart from the buyer himself perhaps.
