Founding Story
Vlad Magdalin wanted designers to build production websites without handing mockups to engineers to recode. He partnered with his brother Sergie Magdalin, a designer, and engineer Bryant Chou, and the three launched Webflow in 2013 and joined Y Combinator that year. In 2014 they raised a $1.5 million seed round from Khosla Ventures, Tim Draper and others. The company then grew for several years without raising a large round. Forbes later described the period before its 2019 Series A as a stretch in which Webflow came close to running out of money.
Founders
Vlad Magdalin
Vlad Magdalin co-founded Webflow in 2013 and was its CEO until June 2024, leading it through Y Combinator and its funding rounds up to the 2022 Series C at a $4 billion valuation. He then handed the CEO role to Linda Tong and became Chief Innovation Officer. Vlad Magdalin was born in 1982.
Sergie Magdalin
Sergie Magdalin co-founded Webflow in 2013 alongside his brother Vlad. As the absolutely critical design visionary, he was obsessed with the idea that graphic designers should not have to learn complex code. He heavily drove the insanely intuitive, highly aesthetic visual interface that allows Webflow to write clean, semantic HTML/CSS in the background while the user simply drags and drops elements. (Exact birth year remains publicly undisclosed).
Bryant Chou
Bryant Chou co-founded Webflow in 2013 and served as its chief technology officer, leading early engineering of the platform. He was still named among the co-founders working with the leadership team at the 2024 CEO transition. (Exact birth year remains publicly undisclosed).
