The story, neutrally told

Centre · 2Cloud security startup Upwind said on Wednesday 28 October that it raised $400 million in a funding round led by Bessemer Venture Partners, valuing it at $3.8 billion. Centre · 1Existing investors including Greylock Partners, Cyberstarts, Craft Ventures, Salesforce Ventures, Alta Park and TCV also took part, and Canapi Ventures joined as a new backer. Centre · 1CNA says the round will fund product expansion and brings total funding since the company's 2022 founding to over $800 million.

Centre · 2The round comes nine months after Upwind's previous $250 million financing; TechCrunch puts that valuation at $1.5 billion, while CNA says no valuation was disclosed for it. Centre · 1CNA also reports that Upwind was valued at about $900 million in a December 2024 raise of $100 million. Centre · 1According to TechCrunch, citing a person familiar with Upwind, the funding nearly fell apart when Datadog, a publicly traded observability company, tried to buy Upwind. The person said Datadog offered no premium over the $3.8 billion venture valuation, so Upwind stayed independent.

Centre · 1TechCrunch reports, citing a person familiar with the financials, that Upwind adds $20 million to $30 million in annualized recurring revenue each quarter and is projected to end the year at roughly $90 million. That implies a valuation of more than 40 times forecast ARR, below the 80 times TechCrunch reported for the security startup Cyera earlier this year. Centre · 1TechCrunch describes the San Francisco company as using AI to secure cloud infrastructure, with a "runtime" approach that alerts on and remedies attacks in active services in real time. Founder Amiram Shachar previously sold Spot.io to NetApp for $450 million. Centre · 1TechCrunch's reporter assesses that an eventual sale remains the most likely outcome, given how few cybersecurity companies have gone public, and a source says Upwind continues to draw acquisition interest. TechCrunch said it had asked Upwind and Datadog for comment.

Framing
CNA runs a short funding brief with bullet points on past valuations and investors; TechCrunch frames the round around Upwind reportedly rejecting a Datadog offer and the likelihood of a later sale.
Emphasis
CNA: round size, investors, funding history. TechCrunch: Datadog bid, revenue growth, valuation multiples.
Leaves out or plays down
CNA does not mention the Datadog offer, revenue or the founder's background. TechCrunch does not list the full investor group or the December 2024 raise.
Charged language
“walking away”
For example
“The latest round, which will fund product expansion, brings the company's total funding to over $800 million since its founding in 2022” — CNA
“By walking away from an acquisition offer, Upwind clearly believes that the company will be ultimately worth more than $3.8 billion” — TechCrunch
