SentinelOne went public this summer, and its first quarterly report as a listed company — a 10-Q filed September 10, 2021 — gives the market its first regular look under the hood. The number to anchor on sits in the key-metrics discussion: a dollar-based gross retention rate, or GRR, of 97% as of July 31, 2021.
For a company at SentinelOne's stage, gross retention is the load-bearing wall. It measures how much recurring revenue the company keeps from existing customers before any expansion — strip out upsell and cross-sell, and ask simply: do customers stay? A 97% GRR says that almost no one who buys the platform leaves. For an endpoint-detection-and-response vendor competing against a much larger, well-capitalized field, that stickiness is the evidence that the product does the job once it is deployed.
The reason this matters more than the headline growth rate is sequencing. A high-growth security name that is not yet profitable is asking investors to fund customer acquisition today against the promise of durable revenue tomorrow. That promise is only good if the customers stay and spend more over time. Gross retention proves the first half; net retention — which layers expansion on top — proves the second. This filing leads with the foundation.
The discipline a markets reader should bring is to treat these as non-GAAP operating metrics the company defines on its own terms, and to read them alongside the GAAP results in the same filing: a young EDR vendor at this stage is still reporting operating losses as it invests in growth. Retention does not erase that; it tells you whether the spend is buying a base that compounds.
From September 2021, the forward questions are clear and unanswered by this single filing: does net retention stay well above 100%, signaling that customers expand as they adopt more of the platform, and does the loss narrow as the base scales? This first 10-Q sets the baseline. It does not yet show the trajectory.
The grounded takeaway: SentinelOne's investment case, in its own first filing, rests on retention. A 97% gross retention rate is a strong opening data point that the platform sticks. Track gross and net retention together each quarter against the still-present operating loss. Source: SentinelOne Form 10-Q (filed Sept 10, 2021), indexed via EdgarBeast.
