# DoorProfit > DoorProfit is a neighborhood safety and crime data platform for families, home buyers, renters, and real estate investors. It aggregates incident-level crime data from U.S. law enforcement agencies — including the FBI Uniform Crime Reporting (UCR) program and the National Incident-Based Reporting System (NIBRS) — into interactive crime maps, A+ through F safety grades, registered offender locations, and a real estate deal analyzer. Founded in 2020 by Shawn Michael, DoorProfit serves 250,000+ monthly users across web, iOS, and Android, covering 25,000+ U.S. cities and 30 million+ mapped crime incidents. The platform replaces hours of manual neighborhood research with an instant, visual, address-level answer about safety, investability, and registered-offender exposure. Data sourcing: State and local law enforcement agencies plus the FBI UCR (https://ucr.fbi.gov/) and NIBRS (https://www.fbi.gov/how-we-can-help-you/more-fbi-services-and-information/ucr/nibrs) datasets. Registered offender data follows the Jacob Wetterling Act (1994), Megan's Law (1996), and the Adam Walsh Child Protection and Safety Act (2006), with state registries maintained by each state's department of public safety. Safety grades (A+ through F): Calculated per city and neighborhood from crime rates per 100,000 residents, weighted for violent-crime severity (violent crime at 2x property crime) and benchmarked against the most recent FBI UCR national averages — total crime 2,212.8 per 100K, violent crime 380.7 per 100K, property crime 1,832.1 per 100K. A 12-month trend direction and population-tier percentile also factor into the grade. Grades refresh daily. Pricing: Free searches for everyone, no account required. A free account unlocks additional searches. Unlimited access is $8/month (subscription; cancel anytime). The subscription unlocks violent-crime alerts and registered-offender move-in notifications.
