why is a startup more able to absorb risk than a large company?
In the IT industry startups provide a different avenue to R&D than the traditional internal investment model. Large companies are expected by the markets to generate profits and hence it is hard to absorb risk of large scale spending on research - it just looks bad when markets have a short term view. Investing in startups has a different model where VCs expect large returns from a few companies. This may be because the start up grows and forms a successful business but it can be because they are acquired by a large company. The unfortunate thing is acquisition looks different on a large companies balance sheet to internal R&D so it can appear better.
