If you are alone, consider taking on someone for sales and finance. Selling to large businesses is a long, slow, drawn-out process, with much "paperwork" and an endless array of reasons for meetings. On your own you'll have no time to do actual dev or design work!

This is one of the reasons I'd probably never go solo unless I had little or no choice. I've seen it up close in a small (5 to 7 people) company selling to enterprise and from further away (I very rarely interact directly with clients & prospects at all these days) as part of a larger company (in both cases working on software to manage T&C and other regulatory requirements, mainly for public facing investment banks and insurance vendors), and I would find it infinitely infuriating.
