The two resources below are some of the best, most-concise posts I’ve found so far to lay out more on running technical diligence for early-stage venture capital investments:
VCs typically want to know the following:
- Are the claims made by the team in the areas of technology accurate?
 - Is the team technically credible and competent?
 - Is the organization capable of executing on their current roadmap?
 - What are the technical strengths, weaknesses and risks of the company?
 
The final report is a lengthy document that includes 
- a summary of the technology developed by the company and its underlying infrastructure
 - technology advantages and risks
 - external dependencies
 - an evaluation of whether the technology is best in class and its future roadmap
 - a summary of the organization and the team’s technical credibility and capability across all product and technical areas
 - product quality and development process and the degree at which future plans seem viable
