There are so many benefits to solo-founding, it's not even funny. Without co-founders, there's no delay in getting started. There's no drama. The development cycle is fast and the code can be remarkably clean. Personally, I make changes to my production code all the time because the whole thing is in my head and I know what effect my changes will have. (And if I screw something up, I know how to fix it in minutes, not hours.) With a team, that's simply not possible.
Investors are going to wake up to this reality soon and accelerators will trip over each other to claim to be the "accelerator of solo founders".
Corollary to this, MBAs and other non-tech types are screwed in the years to come. Engineers won't need them anymore. 1. Make a product. 2. Get some baseline traction. 3. Join an accelerator or raise a seed round, if you need it. 4. Hire the founding team. 5. Profit.
Yes, cofounders can contribute bandwidth, skills, connections, and all sorts of other positive things. They can also contribute friction, disagreement, and various other negative things. It's not a cut and dry benefit.
In my experience, if you have a good brand image and a track record, people just assume you have contingency plans, lots of funding and/or a second programmer on staff.
Founder conflicts are death.
Lots of money changing hands (investment, blow-up, acquisition) is what gets you press.
The main point being, that if you start off by selling a product (rather than getting people to sign up for a free product and then monetizing later) and can get a fraction of the people to sign up then you are in profit. Further, if you own 100% of the company, you are profitable much faster so you don't need to grow as large.
Ex: $30/month * 500 users = $15,000 a month. If that was a bootstrapped business with just a solo founder...$$$
Can you explain how 100% ownership translates into earlier profitability?
Of course, I think what that assumes is that one person could launch a product as quickly as a team. It's easy to imagine a product being complex enough that a team could launch it before a solo founder would.
But ignoring that.. it's clearly faster/easier to build a business to support a single person than multiple people.
Of course the reason people add confounders/employees and take VC funding is because it makes the total pie easier to grow in many cases.
