RedOak Instruments, with a post-money valuation of $7.9 million, is Testing the Waters on NetCapital. The company makes biomedical devices that help in the quantitative measurement of fine motor skills. The instruments allow doctors to measure patients’ functionality, helping them with their diagnosis. Richard Behlmann founded RedOak Instruments in 2008. The proceeds of the current crowdfunding round, with a minimum goal of $10,000 and a maximum goal of $1,000,000, will be used for software development, marketing and sales, development of tech support, manufacturing, compensation, and staff support. The medical device of RedOak Instruments is FDA approved, quick, and non-invasive. The company will either sell or lease the instrument to generate initial revenue of about $5,000 per device per year.
