YC's Head of Design Shows You How To Design With AI
Eve Bouffard, Aaron Epstein, Ev Bufar
Designer Ev Bufar utilizes a voice-first workflow with tools like Aqua, Conductor, and Paper.design to rapidly produce high-fidelity assets for diverse projects, including the Paxyl transcript analyzer and the Soda Zine. Her recent work at Startup School demonstrates an agent-driven production model that generated visual identities for 6,000 attendees through custom shaders and automated speaker assets, while Paxyl analyzes coding agent interactions to reveal developer patterns. By prioritizing massive context density and disposable internal models, Bufar accelerates the design iteration cycle to handle complex branding and interactive web experiences that explicitly cater to both human users and AI agents.

Inside The Startup Building Reusable Rockets
Aaron Epstein, Andy Lapsa, Tom Feldman
Stokes Space, founded in 2019 by former Blue Origin engineers Andy and Tom, is developing the Nova two-stage rocket to achieve full reusability for both orbital stages and drastically reduce launch costs. Backed by nearly $1 billion in funding and operating from a 168,000-square-foot factory in Kent, Washington, the company plans to execute its first orbital launch later this year from Historic Complex 14 in Florida. The team aims to establish daily launch cadence and ubiquitous space access by integrating in-house manufacturing with a proprietary software platform to manage rigorous testing and FAA-regulated operations.

Cursor Head of Design Roasts Startup Websites
Ryo Liu, Head of Design at Cursor, critiques eight AI-generated websites to reveal a widespread pattern of "vibe-coded" homogeneity where default styling and vague messaging obscure core value propositions. The review highlights specific failures across diverse startups, such as broken interactions, inconsistent design tokens, and confusing user flows that prioritize aesthetic trends over functional clarity. Ultimately, the analysis argues that successful AI-built products must move beyond generic templates by establishing unique brand identities, utilizing literal language, and maintaining rigorous consistency to build user trust.

Does Your Startup Website Pass The First Impression Test? | Design Review
Aaron Epstein, Zack Onisko, Zach Anusko
A panel of design reviewers evaluated eight contemporary websites to demonstrate how immediate clarity and functional hierarchy determine user retention over visual complexity. The analysis contrasted successful interfaces like Bottomless and Capacity, which utilized concise messaging and purposeful motion, against flawed examples such as CloudThread and Integrated Reasoning that suffered from distracting animations, inaccessible text contrast, and opaque value propositions. These findings establish that effective web design requires prioritizing the "don't make me think" principle by eliminating cognitive friction and ensuring core products are instantly recognizable within the first five seconds of loading.

Critiquing Startup Mobile Apps with Glide CEO
In a Design Review episode, host and David Siegel of Glide evaluated the mobile usability of five diverse applications to emphasize that software differentiation relies on rigorous design execution rather than code alone. The analysis critiqued Pearls for its effective thumb-zone optimization while exposing critical flaws in Blue Dot's color-coded status indicators and EdenCare's lack of native functionality. Ultimately, the discussion highlighted how context-aware interactions, visual hierarchy, and platform-specific standards determine whether apps like Duffle and Bold Voice succeed in engaging users or create friction that drives abandonment.

YC SUS: Aaron Epstein and Eric Migicovsky give website feedback
Aaron Epstein, Eric Migicovsky
Aaron Epstein, a YC alum and Creative Market co-founder, evaluates the websites of Startup School founders to identify critical failures in clarity, trust signals, and conversion optimization. The review process prioritizes precise value propositions and user benefit statements over visual aesthetics, exposing common issues like vague positioning, confusing navigation, and a lack of social proof across diverse ventures ranging from crypto tax tools to pet insurance. Epstein concludes with a strategic directive for founders to validate their messaging through external user testing and to align their site content immediately with a single, clearly defined use case.
