Jacob Bijani, Tumblr’s creative director and their first designer, is leaving the company after 5 years.

He announced his departure in a blog post where he says that he’s sure the future of Tumblr will be “incredible.”

Here’s his short post:

Today was my last day at Tumblr.

Five years ago I joined a team of four as Tumblr’s first designer, creative director, and product engineer. That team has since grown to 182 of the most wonderful and talented people around.

I’m so proud of what we’ve all created together, and it’s been a privilege to contribute to something beloved by so many. I can’t wait to see what’s next for the product; I’m sure it will be nothing short of incredible.

There’s still a lot more I want to accomplish, and I’m really excited about this next chapter. For now, I’m going to take some time off to digest the last few years. I have about a dozen different projects planned, so expect more from me soon!

There’s no mention of the Yahoo acquisition and no evidence of any link between that and Bijani’s departure, but the timing is hard to ignore. Yahoo announced that they had acquired Tumblr for $1.1 billion less than two weeks ago, and earlier this week Tumblr added more ads to the dashboard.
