David Lawrence was a Harvard Law student when an on-campus shooting involving a police officer sparked controversy over police conduct. He saw that most policing errors occur when officers lack instant access to department rules, so he dropped out and co-founded Blue Voice with Amit Patankar (a Harvard MBA and former Google engineer) and Michael Gropman (a retired Boston police deputy chief). The Boston-based AI startup provides real-time policy guidance to officers in the field.

Blue Voice addresses the problem that officers make decisions from memory or best guess, based on thousands of pages of law, policy, municipal ordinances, and state laws. Previously, officers who needed a specific protocol—like the exact seventh step at a crime scene—had to flip through a 15,000-page manual, wake a supervisor, or use generic AI tools like ChatGPT, which Lawrence says delivered incorrect answers up to 30% of the time. Blue Voice is trained on department-specific laws, local ordinances, and guidelines that general-purpose AI cannot access. The tool always points officers directly to original regulations rather than generating its own answer, leaving the final decision to the officer.

Coming out of stealth three years after founding, Blue Voice has raised $6 million in funding led by SignalFire and Las Olas VC. It now serves 225 county agencies across 25 states and answers a question every minute. Over the past year, its customer base grew elevenfold as police departments reported reduced crime and fewer operational controversies. Lawrence cited two examples: a rookie officer prevented a kidnapping after Blue Voice confirmed that the situation met the legal criteria for “child enticement”; and a department chief was reminded to obtain a third-party mental health evaluation before returning an officer to active duty after a shooting.

Blue Voice competes with PE-backed Lexipol and has also developed cold-case functionality. Lawrence hopes the platform proves that properly deployed AI can deliver public safety benefits without sacrificing civil rights, contrasting with more controversial uses like license plate surveillance. He expressed no regrets about leaving law school, calling this the most impactful career he could pursue.
