| Samdesk | SAM turns unstructured social media into actionable insight and awareness. It also operates a social media management platform for newsrooms. The company allows newsrooms to curate, collaborate, search, annotate, verify, and process around social content, as well as publish and tell stories with social content.When the unexpected occurs, everysecond count - millions of dollars are often lost in just the first few minutes after an emergency. Having accurate and relevant data on the location and impact of an emergency event as it unfolds is of paramount importance to those in corporate security, public safety, and emergency response. However, obtaining this information using traditional news media and data analysts is expensive, slow, and prone to error. SAM Inc. has developed a novel tool which utilizes artificial intelligence (AI) to detect the location of emergency events based on social media chatter. Their proprietary algorithm scans millions of social media posts to detect events such as fire, flooding, tornado, or terrorist attacks, at their earliest stages based on unstructured social media chatter. Following the detection of an event, we use AI and Natural Language Processing (NLP) to verify the source and triangulate location. This information is then provided to decision-makers so they can take appropriate action quickly and monitor the situation as it unfolds in time and space, minimizing the impact on business operations and risk to personnel. When the unexpected happens, every second counts and SAM provides minutes. SAM was founded in 2013 and is headquartered in Edmonton, AB, Canada. | $2.5M | Seed | May 01, 2020 | http://www.samdesk.io/ |
