Leakage! What it is, why it matters, and how to calculate it under VM0047
Leakage in ARR projects is a fraught topic. What is it? How much of an impact can it have on the number of credit generated by the project? How do I calculate it within VM0047? How can I mitigate it so that my projects have greater impact and better economics?
This mini training is a follow up from last month's VM0047 overview webinar. We heard you: developers have a ton of questions about leakage, and investors want to know how to assess risk when considering an investment decision.
This training will be appropriate for a wide range of experience levels, but will include a technical deep dive so you can understand how to implement the methodology yourself, or how to vet a service provider who can help on development and diligence.
