Software development these days: Inhouse or O/S?

Especially these days early stage startups and funding seeking entrepreneurs must cut expenses in order to either succeed or raise money. There are some benefits of O/S your software development (to us...):

• Committed to budget & schedule.
• Having us as your R&D department is very impressive to investors.
• We do only in-house development.
• Working either on hourly basis or fixed price
• Lifetime guarantee for bug fixes (as long as no one else touches the code)
• Higher production rate (we can split the project to more than one developer)
• We could develop also challenging parts of the code and not whole of it.
• Support for large scale production since day one.

Good luck!
