Kirby Winfield is the founding General Partner of Ascend, a Seattle-based pre-seed venture capital firm focused on enterprise AI and early-stage B2B software[1][2]. His investment thesis targets pre-seed and seed-stage companies in artificial intelligence, climate technology, and B2B software across the Pacific Northwest[3][8]. Ascend operates a $25–30 million fund and is recognized as the most active pre-seed VC in the region, having made over 40 investments in two years[4][6][7]. Notable portfolio companies include Overland AI, which provides autonomous ground navigation for the US Defense ecosystem, and Clarity, a deepfake detection platform[1][3]. Winfield evaluates AI opportunities by distinguishing between applied and foundational uses of the technology and advises founders to radically improve problems rather than compete directly with incumbent features[3][5]. Prior to Ascend, he was a serial entrepreneur with four acquired companies and two IPOs, giving him an operator’s lens on startup strategy[3][5].
