Stillwater Associates

What Stillwater Associates does

Stillwater Associates is a privately held transportation fuels consulting firm headquartered in Irvine, California, founded in 1998 by David Hackett, a former Mobil Supply and Trading executive. The firm provides expert advisory services across Strategy & Economics, Policy, Mergers & Acquisitions, Refinery Optimization, and Testimony & Litigation Support, serving refiners, renewable fuel producers, airlines, logistics companies, energy-sector investors, and public agencies including CARB and the California Energy Commission.

Its core products and technology consist of subscription market intelligence publications, including the LCFS and C&T Newsletters and Carbon Market Outlooks projecting credit prices through 2035, distributed via stillwaterpublications.com. These subscription products complement the firm's primary professional services revenue stream through a recurring-revenue model. The firm's competitive position is built on a deep talent bench of senior associates with 30+ year tenures at major oil corporations (Mobil, ARCO, BP, Chevron) and California regulatory bodies, producing proprietary analysis on California LCFS, federal RFS, Cap-and-Trade, and emerging clean fuel programs.

The business operates a sales-led, quote-based engagement model with a relationship-driven GTM motion. As of 2025, the firm reported a 46% new / 54% returning client mix across its six target segments and expanded its senior associate headcount by four. Geographic coverage has historically concentrated on the U.S. West Coast with recent signals of expansion into broader North America, British Columbia, and South Asia. The firm maintains no disclosed external institutional ownership and operates as a founder-led LLC.
