Sometimes life comes full circle. 17 years ago, I was hired by @zscaler and today they acquired @SplxAI, one of our portfolio companies from Runtime Ventures. Very proud to have helped make this happen.

Excited to share the launch of Runtime Ventures (https://t.co/sca224RQml), a VC fund focused on seed stage cyber. Dave Endler and I have been working on this for a couple of years and it's finally time to take the covers off. https://t.co/RAt6TbgM7s

@DecibelVC is one of my favorite firms to work with, not just because it's such a fantastic team, but also because they work to promote our industry overall. I had the great pleasure of sitting down with @dannguyenhuu to share the story of my own personal investing journey.

[Dan Nguyen-Huu @dannguyenhuu]

In the latest @DecibelVC Infra Angel Spotlight, we chat w/ our good friend @michaelawsutton, angel investor in @orcasec @runZeroInc and @GreyNoiseIO
He's had an incredible journey as an operator being the CISO of @zscaler before launching into investing👇

Did Jeff Bezos just use his #TNF  purchase to dunk on Dan Snyder so that he can buy the team? Finally, a conspiracy theory I can get behind. #HTTC  #TNFonPrime

Incredibly excited to add @limacharlieio to the StoneMill Ventures portfolio. When I heard the vision I had to recalibrate my view of the security market. Why buy a generic security solution when you can build a custom, purpose built solution? @limacharlieio will change the game.

[LimaCharlie @limacharlieio]

The team at @limacharlieio is excited to announce that we have raised a $5.45m seed round from @SusaVentures @XeroxVentures @CoFoundPartners @LongJourneyVC Sands Capital @michaelawsutton and @LyticalVentures.
