The valuation of Start-Ups, especially in an early stage of the life-cycle remains a difficult undertaking with a strong tendency towards subjectivity. Conventional valuation methods can generally not be applied, as they either do not adequately account for the characteristics of Start-Up companies or need to be considered as impractical. With fundraising for venture investments continuously increasing, this challenge deserves a closer investigation.

The specific topics of interest in this survey included the knowledge and usage of methods for Start-Up valuation, the criteria and performance indicators considered to drive Start-Up value as well as the current situation and trends in venture investment.
