Several of the hottest companies in triangle tech circles have been added to the presentation list for the Venture 2005 program in April.

Among the latest seven selected for the 22nd annual event, which is called “Where Great Minds Meet Smart Money”, are Inlet Technologies and Liquidia Technologies.

Inlet, which is based in Raleigh, has been drawing global attention for its pioneering means of digitally compressing high-definition content. Inlet’s process makes creating HDTV content cheaper, the company says, and Inlet has generated strong interest at trade shows.

Liquidia is the latest startup from Joseph DeSimone, who has played a role in development of other companies such as a cleaning firm that did not rely on chemicals. Liquidia, which Simone launched along with Edward Samulski, has created new fluropolymer materials that can be used in a wire variety of applications.

Also picked were Mardil, Oriel Therapeutics, Respirics, Stonewall Networks and Triad Semiconductor.

“The entire Selection Committee is impressed with the quality of companies chosen so far to present in Pinehurst,” saidKen Lee, general partner with Hatteras BioCapital and chairman of the conference. “I am certain that this slate will attract a full house of venture investors, and there is still time for interested companies to apply for the remaining presentation slots.”
