Global Alternative Investment Management
Global Alternative Investment Management was founded by Prateek Mehrotra and Robert Riedl, both CFA charterholders with deep wealth-advisory backgrounds. Mehrotra was named to the Investopedia Top 100 in 2018 and the Wisconsin Titan 100 in 2023; Riedl earned the same Investopedia honor in 2019. The firm markets its funds exclusively to high-net-worth individuals and families, institutions, and nonprofits, operating out of Appleton, Wisconsin — far from the coastal venture hubs that dominate its deal flow. The firm cuts across venture and private equity, building concentrated portfolios of direct and indirect stakes in pre-IPO and public companies. Its current and exited holdings show a tilt toward technology platforms: current positions include direct interests in broker Robinhood (via an SPV) and indirect exposure to Marqeta (NASDAQ: MQ) and Toast (NYSE: TOST). Exited positions include direct stakes in Uber, Pinterest, and Palantir, as well as indirect exposure to Coinbase. A dissolved agtech investment was acquired by AgTech Holdings. The firm invests through co-investments, SPVs, and holding vehicles, positioning itself as an access point for investors who cannot write direct checks into top-tier venture rounds. The six-member investment committee carries over 75 years of combined experience. In 2022, the team added Managing Director Robert C. Riedl to lead private capital efforts, bringing deal experience from Wells Fargo Securities and Piper Jaffray — a role focused on fintech and insurtech companies integrating AI. The firm operates under the SEC registration of Endowment Wealth Management, Inc., a structure that outsources compliance while the Global Alts team runs investment selection. No philanthropic or adjacent vehicles are publicly disclosed. Global Alts acts as a bridge — sourcing allocations from individual accredited investors and channeling them into venture-backed names normally gated by large institutional minimums. That model depends entirely on the team's ability to access oversubscribed rounds through manager relationships, making every investment a test of their network rather than a proprietary origination machine.

Frequently asked questions
Who runs investment decisions at Global Alternative Investment Management?
A six-member Investment Committee governs deployment. Managing Member and Chief Investment Officer Prateek Mehrotra chairs that group, which also includes CFO Robert Riedl, COO Tim Landolt, Senior Investment Officer Jamie Brown, Senior Wealth Advisor John Weninger, and Managing Director Robert C. Riedl. The committee structure means no single investment moves without multi-disciplinary sign-off.
How does Global Alternative Investment Management source its deals?
The firm relies on Mehrotra's network of relationships with private fund managers, hedge fund managers, and venture capitalists. Its own materials describe this as the primary origination channel. There is no evidence of a proprietary in-house sourcing engine; the firm appears to invest alongside established managers rather than leading rounds.
Does Global Alternative Investment Management run direct deals or fund commitments?
Both. Its portfolio page labels positions as 'Direct' or 'Indirect,' with indirect stakes held through co-investments, SPVs, or holding vehicles. The firm has held direct shares in Uber, Pinterest, and Palantir, while also gaining exposure to Coinbase and Marqeta through indirect vehicles.
What types of investors does Global Alternative Investment Management serve?
The firm markets solely to Accredited Investors who also meet Qualified Client or Qualified Purchaser criteria — a universe that includes high-net-worth individuals, families, institutions, nonprofits, and university endowments. It does not appear to manage capital for a single family or operate as a multi-family office.
How is Global Alternative Investment Management structured from a regulatory standpoint?
Global Alts relies on the investment adviser registration of Endowment Wealth Management, Inc. under certain ABA no-action letters. This means SEC examination falls under EWM's registration, while the Global Alts team runs fund management and investment selection. It is an outsourcing structure common among smaller fund managers.
