The HarbourVest QIS Edge

The rate at which we produce and collect data is accelerating, and while an increasing number of private market investors recognize the inherent value in their data, select few have the resources or expertise to make use of it all. Using machine learning, artificial intelligence, and data engineering, our QIS team has developed quantitative models and applications to generate actionable insights that both complement and enhance traditional investment processes. Whether through engagement with QIS directly or HarbourVest as a whole, our clients can benefit from these innovative capabilities and enhance their own investment outcomes.

Our comprehensive, ever-expanding capabilities include:

Continuation solutions encompass a host of transaction types in which a GP secures interim liquidity and/or additional primary capital for their LPs in a strongly performing asset, or set of assets, that the GP will continue to own and control. Specifically, they include continuation funds, new funds created by GPs for the purpose of acquiring the asset(s) that continue to be managed by the same GP and capitalized by one or several secondary buyers, or equity recapitalizations involving a direct equity or structured equity investment into a portfolio company. These transactions can also include a parallel investment from the GP’s latest fund into that same pool of assets (a “cross-fund trade”).
