Bloxx, which has its HQ at the Alba Centre in Livingston, plans to use the money to increase product development and broaden its marketing.
The cash pot came from Scotland’s largest provider of angel funding, Archangel Informal Investment, alongside Braveheart Investment Company and matched funding from the Scottish Enterprise Co-investment Fund.
Eamon Doyle, chief executive of Bloxx, said: “With this investment, our shareholders have shown that they share our optimism for continued growth.”
John Waddell, chief executive of Archangels, said: “Bloxx is a solid business and this round will help strengthen the team to deliver on its true potential.”
Headquartered in the UK with sales offices in Holland, the US and Australia, Bloxx has an estimated four million users.
In August, Bloxx added former MSP and enterprise minister Jim Mather to its board.
