Samra argues that as AUM grows, finding undervalued securities becomes exponentially harder. To maintain high returns, he focuses capital only on his absolute best ideas, avoiding the dilution of a "30th best idea." This concentration is a direct response to the constraints of scale and the difficulty of finding true value.

Micah Rosenbloom of Founder Collective argues that keeping fund sizes small is a strategic choice. It aligns the firm with founders by making smaller, life-changing exits viable, maintaining founder optionality, and focusing on multiples rather than management fees from a large AUM.

Alexander Roepers intentionally limits his firm's assets under management (AUM) by closing funds to new investors. He recognizes that, as demonstrated by Berkshire Hathaway, scale is an enemy of high-rate compounding. Staying smaller allows his firm to remain nimble and continue effectively executing its concentrated mid-cap strategy, prioritizing performance over fee growth.

The only effective antidote to the "factory model's" gravitational pull is a firm's unwavering clarity of purpose. This means consciously prioritizing long-term investor outcomes and maintaining underwriting discipline, even if it means saying no to raising easy capital.

Contrary to the industry's focus on capital raising, Apollo identifies the generation of high-quality investment opportunities ('origination') as the primary bottleneck to its growth. This mindset shifts their focus from fundraising to building and acquiring platforms that can source unique deals at scale.

For a new fund manager, the most strategic path is to focus on generating excellent returns on their first few small funds. This builds a track record that ensures future fundraising ability. Rushing to a larger fund size prematurely risks poor performance that can end a career.

Glenn Solomon argues against the trend of asset aggregation, stating that fund size must be determined by the firm's investment strategy. A strategy of making concentrated, early-stage bets naturally dictates a smaller fund size, while letting AUM demand dictate size corrupts the model.

Roepers deliberately closed his funds at $1.3 billion to maintain "style purity." He believes large AUM forces funds into large caps or over-diversification, diluting the impact of stock picking. Capping assets is essential to effectively invest in the $2-15B mid-cap range and maintain liquidity.

Unlike traditional asset managers who can always buy public securities, alternative managers are constrained by their ability to originate unique investments. Therefore, their success should be measured by their capacity to create valuable assets, not just their Assets Under Management (AUM).
