Justine Moore

Justine Moore is a partner at Andreessen Horowitz (a16z) whose work spans AI investing and hands-on experimentation with consumer tools. According to a16z, she focuses on foundation models and applications and has helped lead investments including ElevenLabs, Krea, Black Forest Labs, and Hedra. Her published arguments emphasize how products can make model capabilities useful through connected creative workflows, personal context, and simpler software creation.[3][6][7][9]

Moore has demonstrated creative tools herself. In a January 23, 2025 post embedded in the Krea investment announcement, she reported uploading four photos of herself to create a model that generated real-time images of her. Changing the prompt immediately changed the scene, allowing her to depict herself in different locations.[6]

She coauthored the April 7, 2025 announcement with Anish Acharya and Olivia Moore. Their shared rationale emphasized model aggregation and connected workflows: users could train custom models for a style, character, or object, then generate an image, upscale it, convert it to video, and add sound in one workflow. They valued interfaces that exposed controls for iteration, including reference photos and selectively regenerating parts of an image.[6]

Justine and her identical twin, Olivia, appeared together on Latent Space’s AI-video episode, published July 9, 2025. The episode introduction described their joint work collecting examples of emerging AI-video trends and experimenting with video creation themselves.[1][4]

In her October 22, 2025 analysis, Moore argued that video models were specializing rather than converging on a single model excellent at everything. She identified opportunities both for models that excel at particular tasks and for products that simplify elaborate workflows. Her furniture-staging example combined Ideogram, nano-banana, and Veo3; other creative tasks required additional generation and editing tools. Her conclusion was direct: “We need better end-to-end products.”[8]

In February 2026, Moore argued that vibe coding had mainly served technical power users while leaving everyday consumers behind. She grounded the argument in her own experience: she described having no engineering background and no experience with a command-line interface or integrated development environment before starting. She estimated that roughly half her projects succeeded and said she frequently brought screenshots and error messages into Cursor for help. She had also set up OpenClaw, but felt she was not using its full potential.[9]

Her recommendations focused on the obstacles consumers encounter after seeing a compelling demo: setup, security, imagining what to build, and deployment. She called for browser-based products requiring no setup, security safeguards built in by default, templates or examples that reveal possible uses, and publishing that hides infrastructure complexity.[9]

Before those creative-workflow and coding arguments, Moore explored how AI could organize personal context. In her October 10, 2024 essay, she reported using ChatGPT as a daily journal for several months, recording thoughts and feelings and supplying anonymized screenshots of interactions. She used it to discuss family communication, a difficult work situation, and confusing messages from a friend. She also recalled it surfacing earlier concerns that complicated her memory of a relationship.[7]

She called this idea “exporting your brain”: translating accumulated, unstructured personal context into something that could support communication, self-reflection, and personalized applications. Her proposed companion would ingest text, images, and audio, while users controlled which applications could access which information. She remained uncertain whether one companion spanning all aspects of life or separate personal and work companions would prevail.[7]

Moore’s earlier career was in finance and early-stage investing. She worked on Goldman Sachs’s Private Equity team, then invested at CRV in technology for consumers and small and medium-sized businesses. She earned a BA in Economics and an MBA at Stanford.[3]

She announced her move to a16z on April 7, 2022. The twins’ April 10 Accelerated newsletter described her initial role as a consumer investment partner focused on commerce, including consumer-facing platforms and infrastructure for brands. Olivia had joined a16z’s consumer team the preceding summer; the newsletter also announced their return to jointly writing Accelerated to demystify technology and venture capital.[5]
