Unknown to most, the job of vaporizer plays a central role in the valuation of assets and in the life of funds. To fully grasp the challenges of this critical function, we return with Yann to the concepts and standards in place in the different valuation contexts following asset categories and geographies. We understand that the evaluation work is unfortunately still based on spreadsheets where the risk of error and the use make it particularly inefficient. This is where it gets interesting: friction, risk of error, data to collect and manage, regulations and tedious processes. All the ingredients are there to put some Tech in it. We study concrete practical cases of NAV calculation in VC and Private Equity and see where and how the 73 strings value proposition fits into this whole chain from data collection to evaluation. Yann tells us about the Advisory Board, the first customers like Eurazeo, audibility features, the business model and relations with a whole series of players: service providers, independent vaporizers, GPs, Consultants, Banks As always, we will end with the vision of this young start-up which has a lot to bring to the entire finance industry: from companies to asset managers.
