Upwind Secures $400M Series C at $3.8B Valuation After Rejecting Datadog Acquisition Offer
San Francisco-based cybersecurity startup Upwind has raised $400 million in a Series C funding round, bringing its valuation to $3.8 billion. The round was led by Bessemer Venture Partners with participation from Greylock Partners and Craft Ventures. This significant capital injection follows a period of rapid growth where the company has been adding $20 million to $30 million in annualized recurring revenue (ARR) each quarter. The funding comes after Upwind reportedly declined an acquisition attempt by Datadog (DDOG), as the observability giant did not offer a premium above the valuation set by venture capitalists. Founded by Amiram Shachar, Upwind specializes in AI-driven 'runtime' security to protect cloud infrastructure. While the company remains independent, its high growth trajectory and significant ARR projections suggest it continues to be a prime target for future M&A activity in the cybersecurity sector.
