What Brontide does

Brontide is a specialized tax and assurance firm headquartered in Bethesda, Maryland, serving government contractors, technology companies, and nonprofit organizations on a nationwide basis. Founded in 2015 by Alec Ronin, the firm is structured around three service lines: Audit, Review & Compilation Services; Tax Compliance & Planning; and Employee Benefit Plan Audit Services. Its deliberate vertical focus on three highly regulated industries — rather than generalist accounting practice — is the defining feature of its operating model, with the firm's team and processes built specifically around DCAA requirements, R&D and equity compensation issues, and Form 990 / grant compliance, respectively.

The firm operates 100% domestically with no overseas outsourcing, a positioning the company frames as a data integrity and security advantage for government contractors and data-sensitive organizations. Technology infrastructure is provided through the CountingWorks platform, which delivers the client portal, document management, electronic signature, file sharing, email newsletter, and appointment scheduling capabilities that support engagement delivery. The firm is also affiliated with the BDO Alliance, providing access to additional technical resources and a major-network brand association without the cost structure of full Big-4 affiliation.

Brontide generates revenue through professional services engagements priced on a quote basis per scope and complexity. Its go-to-market relies on content marketing (an educational blog and email newsletter), organic search visibility, and direct client consultation via website contact forms and phone. The firm does not disclose pricing, revenue, or customer counts, and operates as a private, independently-held entity with no disclosed outside investment.
