Brittany Walker

Brittany Walker is a general partner at CRV and a first-check investor in technical founders working in AI, infrastructure software, and frontier technology. She led Eventual’s seed financing and writes in bytewise about how AI agents change software development, distribution, and the way products incorporate professional judgment.[4][3][6][7][8]

Walker led CRV’s seed investment in Eventual, whose open-source engine Daft processes multimodal data. In his June 24, 2025 announcement, cofounder Sammy Sidhu described the infrastructure problem as workloads that combine diverse data types, custom models, and external APIs—requirements poorly served by tools designed for conventional structured data. Sidhu credited Walker with seed leadership; Astasia Myers of Felicis led the subsequent Series A.[6]

Walker also coauthored CRV’s May 15, 2024 investment memo, “#PowerToTheDeveloper CRV’s Investment in LanceDB”, with Murat Bicer and Brian Zhan.[5]

In “When the stack chooses itself”, published May 28, 2025, Walker argued that increasingly automated coding shifts tooling priorities from developer experience to agent experience: how quickly a model can locate state, predict effects, and make safe edits. In her formulation, “What agents value is whatever lowers the error rate.” Her premise of an LLM writing every commit was a hypothetical endpoint, rather than a description of all development at the time.[7]

Walker’s argument extends from code generation to distribution. An IDE and its embedded agent can steer users toward default frameworks, databases, and hosting services while collecting the interaction data generated by development. She argued that combining models with interfaces could create feedback loops from “keystroke → diff → test → fix,” alongside control over pricing and stack defaults. For infrastructure providers, she recommended both cultivating their own audiences and remaining accessible to agents and interfaces owned by others. She acknowledged Swyx as a thought partner on the essay.[7]

In “Expertise as software”, published June 18, 2025, Walker wrote, “A prompt is, functionally, compiled judgment.” She argued that embedding an expert’s playbook in a product lets users borrow expertise through recommendations and assisted execution. Her illustrative examples included pricing defaults that enforce discount guardrails and linting rules that flag departures from scalable API design patterns.[8]

Walker proposed that gathering, auditing, and updating expertise could become a distinct role, potentially an evolution of product management. She emphasized evaluation datasets and user telemetry as ways to establish what good results look like and improve products. In her view, differentiation would depend on how quickly a product incorporates new data, updates its prompts, and equips users with useful judgment.[8]

Walker was Latent Space’s first solo guest cohost for its ICML 2024 recordings episode, published December 10, 2024. The episode covered generative video, diffusion, vision, reinforcement learning, and robotics; Walker highlighted the poster papers “Behavior Generation with Latent Actions” and “PIVOT: Iterative Visual Prompting Elicits Actionable Knowledge for VLMs.” She later hosted the Tiny Teams track at AI Engineer World’s Fair 2025.[1][2]

Before her AI infrastructure investing and 2025 essays, Walker worked in operations and early-stage venture. In her CRV biography, she recalls joining Uber because she was drawn to Travis’ vision of transportation as reliable as running water, then working in driver operations. She says she began her venture career at Dorm Room Fund, a student-run fund backed by First Round Capital, where she led investments in four pre-seed companies.[4]

At Crosscut Ventures, Walker co-created Interchange, a free job board focused on Los Angeles startups. She also began building The Table with Justine Humenansky, identified in her biography as being at Playground Global. Walker describes The Table as a community intended to amplify women’s voices in enterprise and help female founders, investors, and operators learn from one another.[4]
