i-Nalysis president Drew Hession-Kunz

Four of the 20 semifinalists in the Forbes.com Boost your Business Competition are local tech startups: tour guide podcast-maker Audissey Guides Media, online SAT tutor I Need A Pencil, chemical analyzer-maker  i-Nalysis, and rebootless computer software updater Ksplice  made it to the second round. Charlestown-based yoga apparel-maker Plank Design also made the cut, but you don’t care about that, do you?

At the contest’s website, you can watch video profiles of the contestants and vote for a winner.

MHT covered i-Nalysis and its handheld material analyzer in February. Ksplice won the MIT$100K in May, and was also a favorite of our informal panel of judges who weighed in on the prospects of this year’s $100K crop, which you can check out after the jump.
