Investment firms General Catalyst, Khosla Ventures and Arbor Ventures led a $175m Series A round in Heyday, a platform accelerating consumer product brands on digital marketplaces. "We're in the early days of a tectonic shift toward marketplace commerce. Just as the last decade saw the rise of Warby Parker, Dollar Shave Club and other digitally native vertical brands, this decade will see the rise of a new generation of marketplace-native brands. Although the shift has been a boon to entrepreneurs around the globe, most still lack the capital, tools and resources to realize their full potential. Heyday is filling that void," Sebastian Rymarz, Heyday Co-Founder and CEO.
