About Us

A registered advisory practice, built for the long term.

A.R. Duarte, LLC is a business advisory firm organized as a Limited Liability Company under the laws of the Commonwealth of Massachusetts, with its registered office at 2130 Massachusetts Avenue, Suite 1A, Cambridge, MA 02140. Our location places us within one of the country's most concentrated corridors of academic research, technology development, and early-stage enterprise — a setting that directly informs how we advise our clients.

The firm was formed to give founders, small business owners, and mid-sized organizations access to the kind of structured, senior-level counsel typically reserved for larger institutions. We work in close, ongoing partnership with each client rather than through generic packages, treating every engagement as a distinct body of work with its own scope, timeline, and deliverables.

As a legally organized entity, A.R. Duarte, LLC operates with the accountability structure of a formal business: a fixed registered address, defined engagement terms, and a single point of contact for all client correspondence. We believe transparency about how the firm is structured is itself part of the advisory relationship.
