Atomico, founded in 2006 by Skype co-founder Niklas Zennström, stands out in Europe's venture capital scene with a distinctively founder-centric approach. Headquartered in London, Atomico is built by entrepreneurs for entrepreneurs, reflecting Zennström's ethos of empowering ambitious startups to achieve global scale. This is not merely a tagline—Atomico’s team is populated with seasoned operators who have successfully navigated the ups and downs of scaling businesses, making their experience as valuable as the capital they provide.

Atomico is a broad-based tech investor, backing companies from early-stage Series A rounds through to growth investments. Their investment strategy doesn't restrict itself to a single vertical; instead, they seek startups that possess transformative ideas paired with founders capable of executing those ideas on a global stage. This openness has resulted in an impressive and diverse portfolio, ranging from iconic companies like Klarna and Supercell to groundbreaking tech firms such as AI chipmaker Graphcore.

What particularly distinguishes Atomico is its commitment to conscious scaling. The firm actively encourages portfolio companies to grow sustainably and responsibly, supporting founders in considering their broader societal and environmental impacts from the outset. They reinforce this through resources like their annual Conscious Scaling report and the influential State of European Tech report, which provide invaluable insights for founders navigating growth challenges.

When approaching Atomico, founders should expect thorough yet efficient decision-making processes backed by data-driven analysis. Typically leading or co-leading rounds with initial investments ranging from around $5 million up to $20 million, Atomico stays actively engaged through follow-on rounds, ensuring consistent support as companies evolve.

Perhaps Atomico’s strongest asset is the depth of practical, hands-on support it offers to portfolio companies. Founders consistently highlight Atomico’s collaborative ethos, praising their proactive approach in helping with crucial challenges like talent recruitment, strategic partnerships, and international expansion. Klarna CEO Sebastian Siemiatkowski notably described Atomico as genuinely delivering on the often-overused promise of "value-add," while Supercell’s Ilkka Paananen commended them as his "most active and helpful investor."
