About Joost de Valk

I’m a 35 year old web developer, SEO and online marketer. In the early days of my career I worked in several companies, ranging from enterprise hosting to online marketing agencies. This allowed me to work with several large brands around the world.

I founded CSS3.info – the biggest CSS3 resource on the web – in 2006 and sold it in 2009. Early 2010 I built Quix, which was featured in many online publications from Mashable to Lifehacker and ReadWriteWeb.

In 2010 I created Yoast, which focuses on software, training and services for website optimization. Team Yoast currently consists of around 50 people. Yoast SEO, Yoast’s main software product, is currently available for two platforms and active in over 6 million websites.

I live in Wijchen, near Nijmegen, where Yoast also has its main offices. I live there with my lovely wife Marieke, and our four kids:

  • Tycho (2006)
  • Wende (2009)
  • Ravi (2011)
  • Borre (2015)

Outside of work I love to read, do some photography and play games with my kids.
