A Seattle startup led by former VMware execs that sells machine learning as a service has raised $4.7 million in a round led by Chris Rust of Clear Ventures. Tignis sells what it describes as “machine-learning-in-a-box” to help manufacturers, utility companies and smart buildings monitor and improve their operations. This is the second round of financing following an initial investment last year and brings the startup’s total amount raised to $7.3 million. In addition to Rust, the company’s other investors include former VMware CEO Paul Maritz, Harek Kodesh of Silver Lake Partners, and Ashmeet Sidana of Engineering Capital.
