European tech leaders are pushing back against high-profile VCs urging founders to work seven days a week — slamming the grindset mentality as everything from “toxic” to “childish.” 

“Calling on founders to work insane hours nonstop is just bad advice,” Suranga Chandratillake, general partner at Balderton Capital and former CEO of video search engine Blinkx, told TNW. “Even sprinters don’t sprint all the time — rest and reflection is just as important as putting in the work.”

His comments follow a LinkedIn post on Saturday by Harry Stebbings, podcast host and 28-year-old founder of London-based venture firm 20VC. “What European founders need to realise [is that] 7 days a week is the required velocity to win right now,” he wrote, implying that they need to match the infamous grind culture of Silicon Valley.      

Martin Mignot, a partner at New York-based Index Ventures, rallied behind Stebbings. In a LinkedIn post of his own, he applauded the 9am-9pm, six days a week (illegal) work culture adopted by some tech firms in China. “Forget 9 to 5, 996 is the new startup standard,” he said. 

While some echoed their views, many European tech founders and investors weren’t happy with the rhetoric. Amelia Miller, co-founder of return-to-work platform Ivee, called Stebbings’ post “unbelievably toxic.”

“Only bad founders work 7 days non-stop,” she wrote. “It’s poor time management and a fast track to burnout.” Miller also said she thinks that working such long hours unfairly discriminates against parents and those with responsibilities outside the office.  

Chandratillake also warned against taking advice from VCs without experience of starting and running a company. “If you’re a CEO, don’t listen to a jumped-up finance bro in a hoodie who has never done your job telling you how to do it!” he said. 

The lively debate comes amid a broader conversation in European tech over whether workplace culture is holding the region back compared to the US or China. 

In a podcast interview in March, Revolut boss Nik Storonsky criticised European startup entrepreneurs, saying they weren’t working hard enough and valued work-life balance too highly. Those comments followed another lively social media debate earlier this year about whether French founders lacked the “grindset” to succeed.  

However, a recent survey of 128 European founders by early-stage VC firm Antler found that three-quarters of them work more than 60 hours weekly. Almost 20% of them exceeded 80 hours, challenging the notion that European founders don’t hustle. 

Chandratillake said he believes that scrutinising work hours overlooks some of the real challenges founders face in Europe, such as access to late-stage financing. That said, the investor thinks there is a time and a place for the grind.

“Sometimes founders have to work extremely hard and long hours, but that’s not sustainable all the time,” he said. “Building a successful company is a marathon, it takes endurance.”
