What is Big Mountain Data?
• An early stage social impact startup, founded Fall 2014
• We focus on OFFENDERS and their CRIMES
associated with domestic violence
• We take a STEM approach to solving a societal issue
typically addressed with a victim-centric emotional
appeal for charity ($4B spent annually)
• We partner with leading edge technology companies
that align with our vision and goals
captures a lot of DATA
The CDC reports that 1 out of 4 women have
experienced severe physical violence from an
That’s ~40 MILLION women in the U.S.
On the flipside of that equation, there are an equal
number of OFFENDERS. Even if we consider one
batterer stands to abuse 1 - x number of women,
the scale of the “problem” still runs into the millions.
We have data on these offenders today. Further,
we can experiment with new models to merge
unstructured data with the structured data already
in law enforcement databases.
What can the data tell us?
• Who the most dangerous repeat offenders are and their criminal
• When repeat offenders are more likely to commit an act of violence.
• How at-risk a victim is to being re-victimized by her abuser.
• The probability of whether a first-time offender is a good candidate
for behavioral change.
• Where domestic violence occurs (everywhere).
Data that already exists in law
● Calls for Service (Computer-
Aided Dispatch, CAD) 911
● Arrest Data (Record
● Incident Reports

An analysis of the social media
phenomenon that erupted over
the Ray Rice NFL scandal.
We analyzed 225K rows of data
to ask a simple question:
WHY DID THEY?
We published the results.
Then, we open sourced the data.
