Co-Investors
TechOperators is a venture capital firm that invests in cybersecurity companies at the pre-seed and seed stages, and occasionally at Series A. It was founded in 2008 and is based in Atlanta, Georgia. The firm backs technical founders before the market agrees there's a market, usually leads the rounds it joins, and reserves capital for follow-on rounds. Its partners built, sold and bought security companies before they invested in them. Tom Noonan co-founded Internet Security Systems, the company that created X-Force, took it public in 1998 and sold it to IBM in 2006; he is now lead independent director of Intercontinental Exchange, owner of the New York Stock Exchange. Daniel Ingevaldson was an X-Force researcher, then co-founded Endgame and sold it to Elastic in 2019. Kevin Skapinetz was on the founding team of IBM Security, ran its $1.5 billion security software portfolio and shaped its acquisitions from Q1 Labs through HashiCorp. Managing partner Said Mohammadioun built and sold two software companies and has served on sixteen boards. TechOperators is investing from its fourth fund. Portfolio companies acquired include Phantom (Splunk), Endgame (Elastic), Ionic Security (Twilio), Scytale (Hewlett Packard Enterprise), BrightPoint (ServiceNow), Immunet (Sourcefire), Flashpoint (Audax), Phylum (Veracode), Evo Security (Barracuda), Polarity (ThreatConnect) and Tala Security (Intuit).
