We suggest you review your employment contract and examine your non-compete clause. If you own the intellectual property rights to what you contribute to Storybird AND there isn’t a non-competition clause—you’re probably free and clear. If there ARE issues, consider discussing with your manager whether you can contribute to Storybird. You may need to agree on a specific and separate class of work in order to keep them happy.
That said, this should not be considered legal advice. Check with your lawyer if you have any concerns about your situation. We want Storybird to be an exciting artistic and commercial opportunity for you—not a headache. (PS. Many of our artists work for animation studios, publishers, and greeting card companies.)
