The money has come from around 180 investors, according to Industrifonden, the Swedish venture capital fund that carried out the research.
“The Swedish startup sector is booming and continues to punch above its weight in terms of global winners,” the report concludes.
It adds that business angels, international hedge funds and corporate investors have all stumped up money for the growing tech scene so far in 2015, with foreign donors participating in about 40 percent of all Swedish funding rounds.
Among deals involving international participation, investment from the USA was most common, followed by the UK.
But the research suggests that a few wealthy Swedish individuals or companies remain most influential, with Sweden's top ten most active investors involved in half of all deals.
Music technology, software and ecommerce were among the key sectors to attract investment.
The news comes as a global buzz continues around Swedish startups, especially those in the capital.
Following in the footsteps of the likes of Skype, Spotify and Mojang, Stockholm is fast becoming one of Europe's biggest tech hubs. According to separate recent research for investment firm Atomico, Stockholm has the largest number of billion dollar companies per capita outside of Silicon Valley.
Other European cities are also increasingly viewing the Swedish capital as a strong source for international talent, with leading business and technology group Berlin Partner recently linking up with Visit Berlin to try and convince Stockholm-based startups to relocate to Germany.
Jessica Stark, founder and CEO of SUP46, a Sweden-based startup members' group told The Local in September that the initiative was “a great validation of our startup scene (…) a natural development given the amount of exciting startups we have here.”
But there are ongoing concerns about Sweden's infrastructure, most notably its current accommodation shortage, as the startup scene continues to grow.
“The housing market is a bit tricky but there is help to be had,” Julika Lamberth, Business Development Manager for Stockholm Business Region, told The Local last week.
She said the state-funded organisation – set up to drive investment to the city – was consulting with businesses and international professionals in the city to analyse the problem. This includes stepping up efforts to link tech firms with local municipalties and real estate companies in the area.
“We are a facilitator and we can connect interesting players together (…) to make it easier for international companies to continue to attract international talent,” she added.
