But, he said, the landscape nationally is changing for medical marijuana and he was asked to provide his insight as an accountant experienced with data systems to the company.
"If there are states that are going down the road of legalizing medical marijuana, there's got to be a strict, controlled, regulated environment," Bramble said.
The CEO of the company is Jeremy Roberts, a political ally of Bramble's and former Utah County Republican Party secretary.
Roberts said dispensaries in Colorado that now operate as cash-only businesses need better options. His company hopes to provide "end-to-end management," that includes tracking the growth of the plants, verifying prescriptions through a database, processing the sale and remitting taxes.
"We ought to have the systems and tools in place so we don't have basically the wild West," Roberts said.
Bramble listed his role on the advisory board on his Senate conflict of interest form filed last week. The company announced his role on the board of directors in a press release Wednesday.
Bramble, who is vice president of the National Conference of State Legislatures, said he will not lobby anywhere on behalf of the company and he has not been paid, nor does he plan to be paid for his work. He said at some point it is possible that he would receive shares of stock in the company for serving on the board.
