Blue Voice leaves stealth with $6M to put department policy in officers' pockets

A Harvard Law dropout has raised $6M for a Boston startup that gives police officers real-time answers about the rules they are supposed to follow.

Blue Voice is coming out of stealth with the funding, led by SignalFire and Las Olas VC. The company says officers at 225 county agencies across 25 states now rely on the tool daily, and that it answers a question every minute.

Founder David Lawrence was a Harvard Law student when an on-campus shooting involving a police officer sparked intense controversy over police conduct. Concluding that most policing errors happen when officers lack instant access to department rules, he dropped out to tackle the problem with AI. He teamed up with co-founders Amit Patankar, a Harvard MBA and former Google engineer, and Michael Gropman, a retired Boston police deputy chief.

The platform is trained on department-specific laws, local ordinances, protocols and guidelines that general-purpose AI tools cannot reach on the public internet. It also gives officers instant access to detailed school maps on their phones during active-shooter emergencies.

Lawrence likens the product to Harvey, the AI tool widely used by lawyers, or OpenEvidence, a similar tool for doctors.

“When an officer makes a decision, they do so from memory or best guess, based on thousands of pages of law, policy, municipal ordinances, and state laws that they’ve internalized and keep in their head,” Lawrence told TechCrunch.

The alternatives were worse. Before Blue Voice, an officer who couldn't recall a specific protocol — the exact seventh step required at a crime scene, for example — could flip through a 15,000-page manual, wake a supervisor in the middle of the night, or query Google or ChatGPT. Lawrence said consumer AI models delivered incorrect answers up to 30% of the time.

Blue Voice's approach is to point officers directly to original regulations rather than generating an answer on its own the way ChatGPT would. Rather than dictating actions, it supplies the laws and leaves the final call to officers, who combine it with their own field experience.

Lawrence points to concrete episodes. A rookie officer who spotted a man pressuring a young girl to enter his vehicle was unsure whether he had legal grounds to intervene, consulted the app on his phone, and got immediate confirmation that the situation met the legal criteria for “child enticement.” In another instance, Blue Voice reminded a department chief that he could not return an officer to active duty following a shooting without first obtaining a third-party mental health evaluation.
