Quantamentals Management Group

Guy Gotslak, the founder and Managing Member, leads investment decisions and portfolio construction. He designed the firm's hybrid research architecture — a process where machine-learning models generate high-conviction long ideas and his team applies a fundamental review layer before sizing positions. Gotslak has publicly discussed the firm's investment approach with financial media including Barron's, serving as the primary voice on strategy and risk management.

Most systematic equity funds run high-turnover, market-neutral or factor-diversified portfolios that prioritize breadth over depth. Quantamentals operates a low-turnover, long-biased, highly concentrated portfolio — typically holding fewer than 15 names — and subjects every model-generated signal to a fundamental review. The output resembles a discretionary technology portfolio in its concentration, but the idea generation is entirely data-driven, using alternative datasets like satellite imagery, web traffic, and hiring patterns to identify revenue inflection points ahead of consensus.

Public filings and media commentary show a heavy focus on enterprise software, cybersecurity, financial technology, and AI-native platforms — sectors where revenue models are recurring and alternative data signals are predictive. Confirmed names in the firm's historical universe include CrowdStrike, Zscaler, and Snowflake. The firm has not disclosed explicit sector exclusions but has consistently avoided capital-intensive industrials, commodities, and low-growth consumer staples.

Quantamentals operates as a Registered Investment Adviser with the SEC, managing separately managed accounts and pooled investment vehicles. The RIA structure subjects the firm to standard custody, disclosure, and reporting obligations that differ from the typical exempt-reporting-adviser structure many hedge funds use. This regulatory posture signals an intention to serve a mix of institutional and qualified individual clients rather than operating exclusively as a private fund.

Quantamentals has not marketed itself as a long-short manager. The investment process, as described by Gotslak, focuses on identifying long ideas with asymmetric upside — companies where the data signal suggests accelerating fundamentals. Short positions are not a structural component of the strategy. Allocators seeking explicit hedge-fund-style downside protection or pair-trade construction would find this model closer to a concentrated long-only approach with a quantitative entry trigger.
