I just finished the Techstars program as a sole founder, and it's _extremely_ tough to both deal with the demands of an incubator program (mentor meetings, talks, pitch practice and investors) and make progress on the product too.
I don't know enough about your situation to give you meaningful advice, but bear in mind you'll be making a big time commitment as a lone founder in an incubator.
Well... the thing is that I am almost done with my product. I have landed about 15 contracts so by the time I go up to SF I will have clients using the software. Part of my concern is that I am so far along I am not sure if the title "co-founder" would fit anyone.
I spent lots of time working for ad agencies in NYC; while there I noticed that their clients kept asking them to identify and engage influencers. They constantly had a hard time with this and more often than not the client was disappointed so I developed a utility that allows them to identify and engage influencers.
By engage I mean; incorporate them into existing ad campaigns.
That's spooky - I actually have a small contract with a PR firm to do the same thing for Twitter and blogs, and I recently ran into another local startup focused on this.
My advice would be to spend your time growing the business and possibly hiring folks to handle the non-techie side if possible. There's a point at which the risk has been lowered enough that the co-founder level of reward isn't appropriate, and it sounds likely you're there if you're making decent revenue.
