Think Advisors Joins Crete Alliance in a Landmark Deal for Tax Services

WASHINGTON, DC – April 14, 2026 – In a strategic move signaling a major shift in the professional services landscape, national tax consulting firm Think Advisors, LLC, has announced that its highly specialized R&D Tax Credit Services practice will join Crete Professionals Alliance. The deal, which also includes the R&D practice of Think's subsidiary, Black Line Group, integrates deep niche expertise into one of the nation's fastest-growing accounting and advisory platforms.

This partnership is designed to equip Crete’s expansive network with top-tier R&D tax capabilities while providing Think Advisors with the resources and national reach to scale its operations significantly. The move highlights a powerful industry trend: the convergence of specialized knowledge with the power of large-scale, technology-driven platforms, creating a new competitive force in the advisory sector.

“Our partnership with Crete Professionals Alliance represents a great opportunity for us and an exciting new chapter for our R&D Tax Credit Services practices,” said David Mayer, Managing Partner of Think. “By joining Crete, we have an eye on the future, enhancing the tools and support available to our team while remaining true to the culture, values, and personalized service that have defined our R&D Tax Credit Services practices for the last two decades.”

The Rise of the Alliance Model

Crete Professionals Alliance is not a traditional firm. Founded in 2023 and backed by prominent investors like Thrive Holdings, Crete has pursued an aggressive growth strategy that sets it apart from typical private equity roll-ups. The firm operates on a “partner equity” model, acquiring majority stakes in the non-attest businesses of accounting firms while allowing founders to retain leadership roles and minority equity. This strategy has fueled explosive growth, with Crete reporting a staggering 310% revenue increase in 2024 and expanding to include over 40 firms in its network.

The alliance's core value proposition is to empower local and regional firms by augmenting their brand and culture with the resources of a national powerhouse. Partner firms gain access to enterprise-level support for HR, finance, and IT, as well as offshore talent, M&A support, and—most critically—a suite of advanced, AI-powered technology tools. This allows firm leaders to offload administrative burdens and focus on client service and strategic growth.

Steve Stagner, CEO of Crete Professionals Alliance, emphasized this strategic intent. “We are intentionally building a platform that brings together firms with deep, specialized expertise that can support the broader network,” he stated. “Think Advisors is a leader in R&D tax credit services, and their capabilities will be a valuable resource for our partner firms and their clients. This is exactly the type of partnership that strengthens the platform.”

Fueling Growth in a Niche Market

The decision to bring Think Advisors into the fold is a calculated one, targeting a lucrative and increasingly complex market. The global R&D tax credit services market is projected to grow significantly, driven by government incentives promoting innovation and the intricate regulations that require specialized guidance. For companies in sectors from manufacturing and software to life sciences and agriculture, maximizing these credits is a critical financial strategy, yet navigating the rules requires a sophisticated understanding of both tax law and technical operations.

Founded in 2005, Think Advisors built its reputation on this specialized knowledge, employing a team of attorneys, engineers, and CPAs to help over 400 clients identify qualifying activities and expenditures. By joining Crete, Think Advisors retains its leadership and expert team but gains an immediate distribution channel through a national network. This allows them to scale their impact far beyond what would be possible as a standalone entity, providing their services to a much larger client base across diverse industries.

The partnership allows Crete's member firms to instantly add a high-demand, specialized service line to their offerings. Instead of building an R&D practice from scratch, they can now leverage Think's two decades of experience, providing more comprehensive solutions and strengthening client relationships. This symbiotic relationship—specialist firm gets scale, platform gets expertise—is a model that is redrawing the competitive map, creating a formidable alternative to the traditional Big Four firms.

AI and the Future of Tax Advisory

A key element of this alliance is the promise of technology. The press release highlights access to “advanced AI-powered tools and automation solutions,” a claim backed by Crete’s connection to Thrive Holdings, a major investor in OpenAI. This partnership is poised to inject cutting-edge technology into the traditionally manual process of conducting R&D tax credit studies.

In practice, AI can revolutionize R&D tax services by automating laborious tasks. AI-powered platforms can ingest and normalize vast amounts of data from payroll, project management, and accounting systems. Using Natural Language Processing (NLP), these tools can scan technical documents, project notes, and internal communications to identify language that indicates qualifying research activities, such as “prototype,” “testing,” or “iteration.”

This automation dramatically accelerates the identification of Qualified Research Expenses (QREs) and the generation of the detailed documentation required to withstand IRS scrutiny. What once took weeks of manual review can now be accomplished in a fraction of the time, freeing up human experts at firms like Think Advisors to focus on higher-value strategic analysis, client interviews, and substantiating claims. While human judgment remains indispensable for interpreting context and ensuring compliance, the integration of AI promises a new standard of efficiency and accuracy for clients.

By integrating Think’s deep domain knowledge with Crete’s technological infrastructure, the alliance is not just expanding its service menu; it is building a blueprint for the future of tax advisory, where human expertise is amplified by intelligent automation to deliver superior value and results.
