I'm 24 and I started an ecommerce web marketing business about two years ago. I finally have enough cash flow to hire someone and accelerate growth. I'm also a mobile developer. At this point, development is more of a hobby than a startup. I have a few apps out there, but they do not produce nearly as much revenue as my web marketing business.
In both businesses, I've partnered with different companies and formed revenue share agreements. Investing my labor and getting a "piece of the pie" is a lot more intriguing and exciting to me than straight contractual work.
Although my web marketing business is more mature than my mobile development endeavors, I'm much more interested and passionate for development. I have a solid network for future opportunities in both businesses.
Is it a bad idea to try to grow both businesses simultaneously?
