I have a little info on Robert Stevens, possibly some repeats of items you already have, but I hope this helps. Stevens is the founder of Marine Exploration (MEXP) which recently changed its name to In-Ovations Holdings, Inc. (INOH). You might remember that stock symbol as the company whose Secretary-Treasurer, Michael Scaglione, was recently sentenced to a prison term for money laundering penny stock fraud funds.
Stevens, along with Paul Enright and Mark Goldberg (who is current CEO) started MEXP and Stevens was a visible player until they deregistered at the beginning of 2011.
He also was chairman of X-Clearing. At one point it was claimed in a motion by brokerage firm Newbridge Securities, that there was collusion between the transfer agent and Marine Exploration. They stated that the transfer agent (X-Clearing) was owned by Stevens' sister and was not independent.
Stevens promoted MEXP as having $500 billion in potential deep sea treasure findings, but they didn't pay the Captain nor the divers so that quickly fell apart.
MEXP/INOH took another stab at the diving for treasure aspect in 2012, stating on a radio broadcast that they were "moments from leaving the dock to dive for sunken treasure", but that boat never left, and in fact couldn't set sail, due to the fact they had unpaid marina fees and had never paid the aforementioned divers. Now there are negotiations underway to sell the boat for scrap in order to cover the marina bill. Besides that, the boat is now renegade, having no U.S. Coast Guard or American Bureau of Ships documentation. They can't get that documentation thus MEXP/INOH faces very high fines and the Dominican Navy won't allow the boat to leave port even if it could.
The quirky thing to all of this is that Pat Stryker, the Fort Collins, Co., billionaire developer whose grandfather founded Stryker Corp., loaned MEXP/INOH a large sum of money on a convertible promissory note (claimed to be for the boat), and is still lending them much smaller amounts (18% interest) as listed under INOH's most current reported accounts payable. Stryker's notes are listed under BOCO Investments and West Mountain Asset Management. It seems odd for a billionaire to be loaning to a pink sheet with no cash, no revenue, and essentially no operations. It's been rumored her tie-in is to Robert Stevens and Paul Enright.
