Developers value authenticity and depth. This is exactly what the latest developer marketing design trend is all about.
It seems like developer marketers have had a design identity crisis over the past few years. The design aesthetic adopted by developer brands was a corporate, tech-inspired look: flat colors, sans serif fonts, and often just a simple wordmark as a logo. Take a look at the websites of Dropbox, MailChimp, Slack, Buffer, Hubspot, etc., and they all look very similar—a bit like a tech company from the 1990s.
This style of branding has become well known as "Corporate Memphis." There is even an online generator for Corporate Memphis logos that you can use to enter your brand name. It left the developer marketing design space feeling stale and uninspiring.
