“Giving recognition and support to British entrepreneurs is important to me, especially those who are the driving force behind growth-focused businesses,” said Murray.
“Every one of these entrepreneurs is inspirational and dedicated to their businesses and I’m excited to have invested in their team’s vision and work ethic,” he added.
He has not disclosed the sum of his investments.
Murray announced he was joining the advisory board of Seedrs in June 2015 in what he described as a “long-term partnership”.
His latest round of early-stage investments branches out from his previous Seedrs funding, as he invested in three tech-only start-ups - Tossed, Trillenium and Fuel Ventures Fund - last August.
The world number two tennis player was listed as the sixth richest tennis player by Forbes in 2015.
Seedrs has had more than £100m invested on its platform and has funded over 320 deals to date, raising up to £7m on average per month.
As well as having Murray on its books, the crowdfunding platform was boosted in July 2015 when star City fund manager Neil Woodford made a £10m investment into Seedrs.
