What a tangled web…

So, in this round, looks like it was actually S that first poached CRWD in November when Bryan Gale went from CRWD to S. Then in January, CRWD poached 2 execs from S, then put out a BIG PRESSER. I think this presser is due to the fact CRWD had done so as well.

Looking a bit deeper, looks like all three that were poached between know each other pretty well as their time at Cylance all coincided.

Could there be more to the story? Of course there is. Could be a lot of things. Perhaps the 2 that left S for CRWD (Daniel & Raj) don’t like one that came from CRWD (Bryan)? perhaps one of them got passed up for the position Bryan got? Perhaps they think Bryan isn’t good at his job? Perhaps they just wanted a change of scenery.

The fact that CRWD felt the need to put out the presser showcasing poaching from S, to me, is very BULLISH for S.


Hi FinallyFoolin,
Yes, the feeling that I got was that Crowdstrike was saying “We had to poach these guys so that they could help us catch up to SentinelOne.” (Of course I may be imagining that.)


I think you guys are trying to over think something that will never be known. Most likely these guys just wanted their underwater RSUs to get repriced or did not get enough repricing. Changing companies gave them more RSUs and a much lower grant price with a company with a different/better risk profile.



Hi Zane, there’s no such thing as underwater RSUs. They may have underwater options and RSUS that weren’t worth what they were when they were granted.

Bottom line for me CRWD got two C-level hires from S. A third GM-level person resigned recently, who knows where he goes. This isn’t healthy for S, and it is good for CRWD. S poached a VP level person first. Bear in mind, typical company, there are 3-5 VPs for every C level. So VPs are a lower level person (although undoubtedly senior and important). So the fact that S poached a VP isn’t even close to symmetric.

These guys are industry leaders. They know the tech and the commercial situation intimately. Far greater than you or I ever could (unless you happen to be a 20 year executive level security professional…I am not).

at a minimum, they must have felt that CRWD was a more compelling opportunity for them, all things considered. At maximum, they felt that CRWD would win or has the more compelling position.

I am sure everyone will draw their own conclusion but this is mine.




I listened to the Microsoft call yesterday, and some things really stood out to me when Satya talked about their security solutions.

Since the title of this thread is „The Empire strikes back“ - I thought it is the perfect place to post this.

From the call:

„…Over the past 12 months, our security business surpassed $20 billion in revenue as we help customers protect their digital estate across clouds and endpoint platforms.

We’re the only company with integrated end-to-end tools spanning identity, security, compliance, device management, and privacy informed and trained on over 65 trillion signals each day. We are taking share across all major categories we serve. Customers are consolidating on our security stack in order to reduce risk, complexity, and cost. The number of organizations with four or more workloads increased over 40% year over year.“

U.K. retailer Fraser Group, for example, consolidated from 10 security vendors to just Microsoft. Roku moved identity and access management to the cloud with Azure Active Directory. And Estella Pharma, Ferrovial, and University of Toronto all switched to Microsoft Sentinel because of our integrated XDR and SIM capabilities.

So maybe it‘s good to not focus to much on little fights between two vendors. There are also other big companies competing for share.

Let me add something about the call in general, for the people that didn‘t follow the results:

Performance in the U.S. was weaker than expected. Azure grew 38% this quarter (cc) but exited the quarter with around 35% growth. Next quarter they expect growth to be around 30-32% (cc) - which is weaker then expected. Could be a rough year for most of our companies.



Rob agree with your assessment that CRWD must have been an attractive enough alternative to leave S. Otherwise, they would not have left, even for the SBC. A C-level or GM move is dangerous in that they can bring their people or friends along with them. These folks also likely have an unattractive number of RSU grants in their current job.

The 2021 summer IPO price of S was about ~$46. Most hires before that date had stock options much less but very unlikely below the current price of $15. So they are underwater with no hope in sight. Hopefully for them, they exercised already.

New hires (post IPO) are normally granted a dollar amount for RSUs in addition to their base salary in their offer letter. The number of RSUs granted are calculated at the first BOD meeting after the new hire start date ~10-30 days. The BOD sets the stock price for RSUs (usually market price but not always). This stock price is divided into the offered RSU dollar amount to give the number of granted RSUs. RSUs vest at some period, frequently every year for 4 years. Once vested, the owner can hold or sell on the fully taxable granted shares. The SBC reward is directly impacted by the number of vested RSUs.

The other shoe may not have fully dropped yet on S and will likely not be publicly visible. There could be a further brain and talent drain. But this drain can happen in both directions during a market decline like we experienced in 2022. Talent will chase a new job unless the company grants additional RSUs. I must correct my statement that the RSUs get repriced…Rob you are right, they do not. Just more RSU grants can be issued to retain the talent.
