Calming chronic pain
MicroTransponder
Dallas

While many of last year's business plan competitors have found the venture capital market tough to crack, fourth-place winner MicroTransponder has triumphed. Late last month the medical-device startup closed a $2.2 million funding round.

Why are investors lining up? The founders developed a device that allows doctors to treat chronic pain and other neurological maladies through wireless signals. In the past year the company has grown from four to 10 full-time employees and plans to finalize its prototype this spring. The startup will complete pilot trials by the end of the year and then hopes to sell its technology to a huge medical device company such as Boston Scientific or Medtronic.
