Mortal Online has been creeping its way towards success since its launch last year, and not unlike the mass of polyps in my face, removing the problems is going to require a lot of work, time, and perhaps some major surgery. As it stands, however, Star Vault has taken the “no publicity is better than bad publicity” approach, one that I myself have encouraged and several other MMOs featured here are currently using, and Henrik Nystrom is holding off on advertising Mortal Online until the game reaches a marketable state.
Unfortunately, development doesn’t pay the bills, and likely not even Henrik can continue using the family coffers forever. Star Vault, on a Swedish trading website, announced that 9.9 million Class B shares will go up for sale for .36 SEK each, a figure which rounds to about 5 cents USD per share. I don’t think it takes an expert to know that those are extraordinarily low stock prices.
Hopefully this influx of cash will mean faster development toward that era of marketability that Star Vault so greatly desires and likely needs at this point. I mean, it has to get worse before it can get better, right?
More on Mortal Online as it appears.

The only way to add funds to the development is by buying the game or game time. Buying shares does not add to development funds.
But you are right on the low stock value at the moment, it can only go up from here, the game have improved 100x since beta and still improving and they have added lots of nice sandbox features never seen before in other mmos.
The money invested in the company does not comes from Henriks Family, his network invested the first millions in the company, the rest comes from the stock market when it got listed.
