What Whetstone Capital Advisors does
Whetstone Capital Advisors, LLC is a privately held, value-oriented investment advisory firm headquartered at 2001 Shawnee Mission Parkway in Shawnee Mission, Kansas. The firm operates a research-intensive investment process centered on identifying businesses with discernible competitive advantages in industries benefiting from secular growth, focusing its research within stated circles of competence covering software, payments, internet technology, and media. Its public-equity strategy combines a concentrated long portfolio of typically 15-20 high-conviction ideas with a more diversified short portfolio that includes both stand-alone shorts based on fundamental research and positions used as hedges against long exposure.
The firm serves institutional investors and high-net-worth clients, generating revenue through investment management fees under a subscription/recurring model. Pricing is not publicly disclosed and is negotiated on a quote basis. Distribution is conducted entirely through direct client relationships and referral networks, with no marketing channels, channel partnerships, or intermediary distribution arrangements disclosed. Recent SEC-disclosed activity in Q4 2025 and Q1 2026 — including exits from GitLab and monday.com, an increased stake in Golden Matrix Group, and a shareholder governance filing at Health Catalyst — demonstrates ongoing active mandate management, but no AUM, revenue, or client-count figures are publicly available.
The team consists of four members: David Atterbury as Portfolio Manager and Managing Partner (prior stints at Brown Brothers Harriman's 1818 Partners Fund, DS Advisors, Return Holdings, Ashkenazy Acquisition Corp, and Merrill Lynch; Columbia MBA with Graham & Dodd Heilbrunn Center participation), Andrew Carlson as Investment Partner (joined 2011), and analysts Jordan Hulet and Jonathan Huhn (both joined summer 2021). The firm is organized as a Kansas LLC with no parent company, no disclosed institutional backers, and no public listing. There are no patents, trademarks, certifications, partnerships outside of portfolio investments, or disclosed AI/ML capabilities; the stated differentiator is process discipline and human fundamental research.

Whetstone Capital Advisors competitors and assessment
Company assessmentDirect peers
- Lone Pine Capital: Lone Pine runs a long/short equity book with deep concentration in technology, internet, and media — directly overlapping Whetstone's stated circles of competence. Comparable in being a fundamental, research-intensive L/S shop, though substantially larger.
- Pershing Square Capital Management: Bill Ackman's concentrated, high-conviction fund running a small number of large long positions with explicit activist posture. Directly comparable concentrated-portfolio philosophy and willingness to engage on governance.
- Altimeter Capital: Brad Gerstner's tech-focused long/short fund with concentrated public-equity positions in software and internet. Highly comparable sector mandate and concentrated-portfolio style.
- Scion Asset Management: Michael Burry's value-oriented fund running concentrated long/short equity with a fundamental-research edge. Directly comparable as a small, conviction-driven, value L/S manager.
- Maverick Capital: Long/short equity fund running a concentrated, research-intensive book with sector specialization. Comparable as a fundamental, conviction-driven L/S manager.
- Greenlight Capital: Founded by David Einhorn, Greenlight is a long-established value-oriented long/short equity hedge fund running a concentrated book with both longs and shorts. Directly comparable to Whetstone in philosophy (fundamental value investing with short overlay) though at vastly greater AUM scale.
- Whale Rock Capital Management: Tech-concentrated long/short equity fund focused on software, internet, and payments — strong overlap with Whetstone's sector circles of competence and concentrated-portfolio approach.
- DS Advisors: Smaller value-oriented hedge fund where David Atterbury previously worked. Directly comparable philosophy and scale profile to Whetstone and represents the closest stylistic lineage.
- Coatue Management: Tech-focused long/short hedge fund with concentrated positions in software, internet, and payments — a near-perfect overlap with Whetstone's mandate. Closest large-scale direct peer in sector focus.
Broad incumbents
- Baupost Group: Seth Klarman's value-oriented investment firm running a multi-strategy book with significant long/short equity exposure. Comparable value-investing philosophy, though considerably broader in mandate and larger in scale.
