The physicists behind hydrofusion.com (and ecat.com) are not _just_ physicists.
As I noted in an earlier thread, Sandstrom is a VP at DBRS since 2007, a financial rating service in Canada. Think Moody's, but a little smaller. Not a lot smaller, though: http://www.dbrs.com/research/211085/dbrs-strengthens-emea-structured-finance-group-with-senior-hire.html Holm was/is CEO of a software company working on advanced search algorithms: http://www.mindmetric.com/company_mngt.html Sandstrom and Holm have published a paper together in 1999 (on curvature relations in product manifolds): http://fy.chalmers.se/OLDUSERS/tfens/paper2.pdf Nothing conclusive about a third member of the team, Staffan Helgesson ... but the only one I could find that makes marginal sense is the Managing Director of a VC firm, Creandum.
