Money will be invested in sales infrastructure
Touch Bionics has secured £2.5 million of investment to expand its sales team.
The Archangels funding group and the Scottish Venture Fund are providing the backing for the prosthetic limb company.
The money will be used to increase its sales force and to support product development.
The Livingston firm recently unveiled its latest i-limb and virtua-limb technology.
Ian Stevens, CEO of Touch Bionics said: "We are pleased to have secured this funding from Archangels and the Scottish Venture Fund, which will help support our growth objectives.
"Our new products, backed by a growing sales and support organisation, will ensure that we continue to provide the best prosthetic solutions to our customers, and this investment provides us with the financial backing to support these objectives."
John Waddell, chief executive of Archangels, said: "Touch Bionics presented us with a business plan that showed both innovation and vision. The company has already established itself as a world leader in its field and we think the investment will help consolidate that position and develop the next generation of products."
