Seattle startup Strike Graph raised a $3.9 million seed round led by Madrona Venture Group. The company, founded less than a year ago and spun out of Madrona Venture Labs, helps customers prepare for the cybersecurity certification process. Most B2B organizations need to pass cybersecurity audits to ensure their service meets security and privacy standards. Strike Graph says its customers can earn a SOC 2 Type 1 certification in 45 days and save $50,000 in consultant fees thanks to automation and customization features.
