Black Sheep Law Llc.

What Black Sheep Law Llc. does

Black Sheep Law LLC is a transnational corporate law firm founded in 2022 by Mtra. Hilda Alicia Castillo Castrejón and headquartered in the United States as an LLC, with operational presence in both the USA and Mexico City. The firm serves two primary client segments: US companies seeking to establish legal presence in Mexico and large-scale, government-subsidized Mexican entities requiring representation inside Mexican jurisdictions. It offers four practice areas — Corporate Law, Energy Law, Complex Litigation, and Civil Law — with a focus on cross-border corporate matters, company formation, regulatory compliance, and navigating Mexican bureaucracy.

The firm operates as a professional services business, generating revenue through legal service fees (hourly, fixed-fee, or retainer arrangements) rather than a technology or product model. It has no proprietary technology platform, no AI/ML capabilities, and no software product. Its core deliverables are human legal advisory and representation. The go-to-market is sales-led and direct: potential clients reach the firm through educational blog content on Mexican corporate law topics or via a website contact form, followed by professional consultations.

The firm is bootstrapped, founder-owned, and operates with a stated team of only two individuals (Founder & Partner and Operations Manager/Legal Intern). To extend its delivery capacity without proportional headcount growth, Black Sheep Law relies on a core partnership ecosystem: TMF Group for global administrative services referral reach, Notaria 208 (Agustin Gutierrez Katze) for 30+ years of Mexican notarial expertise, and (re)ALIGN Growth Expansion Sherpas for cross-border business development. There are no institutional investors, no funding rounds, no acquisitions, and no disclosed revenue figures.
