Venture capitalists will insist on a professional team coming in, including a CEO to execute the idea. One-man armies are passe. Integrity and commitment are attributes sought for. The venture capitalist can provide the strategic vision, but the team executes it. The idea and its potential for commercialization are critical.
Venture funds look for a scalable model, at a country or a regional level.
Otherwise the entire game would be reduced to a manpower or machine multiplication exercise. For example, it is very easy for Hindustan Lever to double sales of Liril - a soap without incremental capex, while Gujarat Ambuja needs to spend at least Rs4bn before it can increase sales by 1mn ton. Distinctive competitive advantages must exist in the form of scale, technology, brands, distribution, etc which will make it difficult for competition to enter. All investment decisions are sensitive to this. Most deals fail because of valuation expectation mismatch.
