When it comes to securing Industrial Operations environments, we believe humans should always be in the loop as actions in the cyber-physical world have real consequences. Threats are increasing faster than we can hire and train employees. We provide an intelligence augmentation platform that acts as your “cyber-sidekick”. Galvanick helps industrial companies secure their operations by reducing the time to detection of anomalous behavior on their most sensitive assets. The Galvanick cloud-native analysis platform aggregates telemetry from industrial environments and hosts systemic models that enable operators to quickly understand the difference between, and context around, both normal and abnormal behavior.

Point is the first FinTech platform where homeowners can sell equity in their homes, giving investors access to a new asset class – owner-occupied residential real estate. Historically, the only way a homeowner could unlock the wealth in their home was to take on further debt. Now with Point, they can de-leverage and diversify their wealth so they can invest in their small businesses, make home repairs, pay off debt, or go back to school. Point is the first consumer finance product that is truly aligned with the customer. When the homeowner does well, Point and its investors do well. We are a well-financed, fast-growing startup backed by top investors like Andreessen Horowitz, located in downtown Palo Alto just minutes from Caltrain. Point's founders have previously co-founded TrialPay (acquired by Visa), Yub (acquired by Coupons.com), Metails (acquired by Buy.com), SiteAdvisor (acquired by McAfee), Affirm, SendGrid (acquired by Twilio), and TXN (aquired by Envestnet).
