Most web dev agencies seem to be under 20 employees. Is that the limit of the business model? Arguably, this is basically a small business.<p>Exceptions could be companies like 37signals, which develop their own proprietary products. Successful ones seem to be rare.<p>It seems many dev shops are going this route. So if you have the capital, wouldn't it be smarter to start with product development?
Lecture 20 of How to Start a Startup[1] touched on this.<p>> In the beginning of a company, there is no management. This actually works really well. Before 20 and 25 employees, most companies are structured with everyone reporting to founder. It's totally flat. That's really good. That's what you want because at that stage, it's the optimal structure for productivity.<p>> What tricks people is when lack of structure fails, it fails all at once. What works totally fine at 20 employees is disastrous at 30.<p>This is pure speculation, but I can imagine that this limits the size of many companies. Most web dev agencies I'm aware of weren't founded as hyper-growth startups that are willing to push through that barrier.<p>[1] <a href="http://startupclass.samaltman.com/courses/lec20/" rel="nofollow">http://startupclass.samaltman.com/courses/lec20/</a>
Pixelpark Germany (<a href="http://www.publicis.com/capabilities/" rel="nofollow">http://www.publicis.com/capabilities/</a>) started 1991 and scaled to 500 full-time employees around 2009. Currently claims 800 (not sure how many full-time). They even IPO-ed. No product on their own, it's still doing web-solutions for customers only. It just covers full brand management, research, SEO/SEM etc as well now.
You see under 20/30 employees in a lot of businesses; the reason (IMHO) is that this is a natural choke point. Any more than 20 employees and the principle has to delegate, hire HR, management, and develop processes—it's a natural point at which a single leader cannot scale and a business has to transition into "a company".
If you're located in a developing country clients will literally "rain" to you. It's a good business because the ROI is really high, but it's more of a "red ocean". In the short term it can work, but if you really want to start a business, shouldn't you be thinking in the long term?
