What We Do
Legal counsel and strategic advisory for technology companies operating in the national security space.
Flagship Service
Fractional General Counsel
Most technology companies do not need a general counsel full-time. But the ones operating in the national security space cannot afford to go without one.
77 Meridian provides embedded legal and strategic counsel for technology and AI companies: an ongoing partnership, not an outside firm you call when something goes wrong. DJ Rosenthal operates as an extension of your leadership team: attending board meetings, reviewing contracts, advising on regulatory strategy, and handling the day-to-day legal decisions that shape how your company operates.
What Fractional GC covers:
- Corporate governance and board advisory
- Commercial contract negotiation and review
- Regulatory compliance strategy
- National security risk assessment
- Day-to-day legal counsel and operational support
The distinction between a lawyer you call and a partner who calls you. Proactive, not reactive. An embedded counsel who knows your business, your team, and your risk profile, not an outside firm billing by the hour for context they have to relearn on every call.
Every engagement is led directly by DJ Rosenthal, not delegated to associates. Clients get senior-level counsel on every matter, every time.

Contact DJNational Security Regulatory Compliance
Companies in the defense and intelligence sectors operate under a distinct and evolving regulatory framework. 77 Meridian advises on navigating that environment, from facility security clearances and FOCI mitigation to ongoing compliance program design and monitoring.
This is not optional compliance. For companies holding classified contracts, working with cleared personnel, or subject to national security oversight, the regulatory environment is the operating environment.
- Third-party compliance auditor
- Technical control design and implementation
- Continuous monitoring and program optimization
Facing a compliance question in the defense or intelligence space?
Contact DJAI Trust, Safety & Responsible Development
The national security implications of artificial intelligence extend well beyond defense applications. 77 Meridian advises AI companies on responsible development practices, model integrity, and the prevention of misuse by threat actors, at the intersection of emerging technology and government oversight.
As regulatory frameworks for AI continue to develop, companies building in this space need counsel who understands both the technology landscape and the national security policy that will shape it.

Contact DJGovernment Engagement & Contracting Strategy
Selling to the defense and intelligence communities requires more than a good product. It requires understanding how those institutions evaluate, procure, and trust technology providers. 77 Meridian helps technology companies build government relationships, navigate procurement processes, and position themselves as credible partners to the national security community.
If your company is trying to sell to the government and does not know where to start, that is precisely the conversation 77 Meridian is built for.
