The world number two invested an undisclosed amount in perks and benefits scheme Perkbox and peer-to-peer travel money platform WeSwap, helping them on their way towards their crowdfunding goals.
In return for his investment, the Wimbledon winner has taken an unknown amount of equity in each of the businesses in the hope that they'll grow considerably.
"I'm continuing to grow my portfolio through Seedrs and have tried to choose companies from different sectors as much as possible," said Murray in a statement.
"I was interested in Perkbox as I employ a number of people through my own sports management company, the 77 Group, as well as a number of independent contractors like physios, coaches and trainers. I'm sure they'll all be wanting to hear lots more about Perkbox. WeSwap was interesting to me because I travel so much around the world - I thought this was a really clever idea and could immediately see the gap in the market for this business to work."

Founded in 2015, Perkbox claims that it already has over 300,000 paying members including British Gas, BUPA, and Deliveroo. It also says it has generated more than £14 million in revenues since launch.
WeSwap has raised a total of £1.8 million from over 2,200 individual investors including Ascot Capital and is currently overfunding by 185%. In the past 12 months, the startup claims to have grown by 204%, attracting over 200,000 new users in the process.
Jeff Lynn, CEO and cofounder of Seedrs, said in a statement: "It's great to see how active Andy has become in early-stage investment and his recent investments on Seedrs into Perkbox and WeSwap reaffirm this. He is a great example of an investor who understands this asset class and the importance of building a broad investment portfolio, into which these two disruptive tech brands will add even more diversity."
