Hybrid waterfalls (sometimes called deal-by-deal waterfalls with a clawback) give fund managers the flexibility to collect carried interest earlier in the fund’s life – a huge benefit to the GP and employees with carry – but they also introduce operational complexity and clawback risk. Most funds handle these calculations in Excel, turning critical financial decisions into manual spreadsheet gymnastics. It’s messy, error-prone, and often leads to unnecessary risk.
Automating hybrid waterfall calculations transforms fund operations, enabling GPs to make real-time decisions that mitigate clawback risk while still benefiting from earlier carried interest distributions. With proper automation, fund managers can perform subjective decision-making by strategically allocating underperforming unrealized deals to specific tiers, and immediately see how these decisions affect current carry before finalizing distributions,
This strategic approach not only protects GPs financially but also strengthens LP relationships by ensuring accurate, transparent, and auditable distribution calculations. Let's explore the challenges of managing hybrid waterfalls in Excel and how Maybern’s unique approach to waterfall management addresses these challenges.
While hybrid waterfalls offer the significant advantage of allowing GPs to receive carried interest earlier in the fund's life compared to European waterfalls, they also introduce increased operational complexity and risk that is difficult to manage effectively with Excel alone.
Challenges include:
In a world with increasing LP demand for accuracy and transparency, having a systemized approach to waterfall management that addresses the above challenges is critical.
Given the inherent risks of having a more complicated waterfall managed in Excel, there are substantial benefits to automating the waterfall in a controlled environment. Maybern's platform is built to flexibly handle waterfall calculations that reflect your unique LPAs, in an intuitive, auditable, and easy-to-use workflow.
Beyond the basic mechanics, Maybern’s automated hybrid waterfall solution delivers strategic business advantages that can fundamentally transform how fund managers operate:
Hybrid waterfalls represent just one example of waterfall complexity that Maybern simplifies. In the coming year, Maybern will expand support for additional waterfall complexities, including multiple waterfalls per fund, split-stream waterfalls where different distribution proceeds follow distinct paths, and cross-waterfall tests that analyze multiple waterfall runs.

Quick reference for this topic.
A hybrid waterfall combines deal-by-deal distribution mechanics with fund-level catch-up and clawback provisions. The GP receives carried interest on individual realizations as they occur, but the fund maintains a whole-fund reconciliation that adjusts those payments if later deals underperform. The structure rewards GP performance early while preserving LP downside protection.
European waterfalls calculate carried interest only after the entire fund returns committed capital plus the preferred return, which means the GP waits years for distributions. American (deal-by-deal) waterfalls pay the GP carry on each realization as it occurs. Hybrid sits between the two: deal-by-deal GP payments with a whole-fund safety net that requires the GP to return earlier distributions if subsequent deals miss the hurdle.
Clawback risk emerges when early deal exits generate GP carried interest, and later deals underperform enough that the fund's overall return falls below the preferred return hurdle. The GP owes back the difference at fund wind-down. Without continuous reconciliation, GPs can spend distributions that they will be legally required to return years later.
Hybrid calculations require continuous reconciliation between deal-level and fund-level views, recalculated every quarter as new capital activity occurs. Spreadsheets force this logic into cells that must be rebuilt for every new investor side letter, every new realization, and every change to a clawback assumption. Audit teams routinely find errors in spreadsheet hybrid waterfalls during quarterly close reviews.
The system has to represent waterfall logic as configurable rules rather than cell-by-cell formulas. The same rule set runs deal-by-deal distributions, the whole-fund hypothetical reconciliation, and the clawback exposure calculation every quarter. Outputs need to be traceable to the specific capital event and rule that produced them, which is what makes audit defense cheaper than the spreadsheet alternative.
