- Save money on external consultants in the first stages. Also this lets you evaluate and hire the right programmers (avoid the 6th reason to fail of Paul Graham http://www.paulgraham.com/startupmistakes.html)
- To be able to liaise with technical communities, partners, resources, and information. The company will know a lot more about tech issues than other companies who only go to conferences, and receive advice from software vendors and other commercial channels
- It is not a great idea to externalize decisions about your core business
- A technical founder could be a source of innovation to differentiate the company from competitors and could bring to the company some ideas that are impossible to buy- It is easier for a technical person to get management skills than for managers to learn about programming, system operations, network management and other topics

5 problems when you have a technical co-founder
- Biased decisions based in the technical background, could get trapped in their knowledge comfort area
- Many technical people fear finances, management stuff and other startup tasks
- They usually get enthusiastic with technology and forget the business and the big picture
- If you let to the techie to do a public presentation, 95% of the public will get lost and bored with the incredibly precise and detailed information about tech issues. (Alex Barrera dixit!)
- It doesn’t matter how many MBAs and management courses they attend, a techie always will be a techie. (http://programmersatwork.wordpress.com/bill-gates-1986/)

To conclude, it is essential to have both a high level of programming experience combined with business acumen within the skillset of the startup founders. This can successfully work where the startup’s skillset is divided into a techie and a business founder or alternatively where both founders have both technical and business skills
