“I was initially brought in as a SETsquared mentor for Symetrica. They were looking at medical applications, but I recommended they move into homeland security. Symetrica secured investment from NESTA on this basis.”

“SETsquared provided a lot of training to help us prepare for pitching to investors, and helped make useful connections via the US embassy. We went through SETsquared’s business review panels with a number of external advisors, who critiqued our business plans and strategies. The panels helped sharpen out strategy and made us more ready for when we looked for investment.”

“We pitched at the first investment showcase, which resulted in an investor walking up to me afterwards and saying they would invest in Symetrica – which they subsequently did.”

“Perhaps the most important role of SETsquared was to bring in an experienced person to mentor Symetrica. One of the best things about SETsquared is the depth of qualified mentors that it can bring in.”

“SETsquared provides a supportive but challenging environment to somebody starting a small business. It makes the management of the company think carefully about what they’re going to do and how they’re going to do it, and enables them to have that critiqued by experienced mentors.”
