Arcada Labs
# Arcada Dev (Arcada Labs) Arcada Dev is the product studio behind **Arcada Labs** — a team building “creative environments” that turn fuzzy human traits (like taste, aesthetic judgment, and play) into something measurable. Their bet is simple: if we can’t measure what humans *prefer*, we can’t reliably improve AI that makes things for humans. --- ## What Arcada Dev builds Arcada Labs frames its work as three “arenas”: * **Taste → Design Arena** — measuring what “looks right” * **Sound → Audio Arena** — measuring what “sounds right” * **Play → (coming soon)** — measuring what “feels right” Think of these as public training grounds for subjectivity: instead of debating taste endlessly, you run controlled matchups, collect votes, and let the data tell you where models actually land. --- ## Flagship: Design Arena **[Design Arena](/tools/design-arena)** is a crowdsourced benchmark for AI-generated design — spanning real-world creative tasks (like UI/front-end design, images, audio, video, and more) and evaluating them with live, organic user feedback. ### The core mechanic (simple, but sharp) Design Arena uses blind, head-to-head tournaments: * Two model outputs face off on the same prompt/task * The model names are hidden to reduce brand bias * Users vote for the better result * Those matchups roll up into a public leaderboard ### How ranking works (in plain English) Every vote is treated like a “match.” Over many matches, Design Arena estimates how likely each model is to beat another and converts that into a rating you can compare across the field (presented in an Elo-style form). --- ## Why it exists LLMs can ace tests and proofs, but design failures are painfully human: unreadable contrast, awkward layouts, weird spacing, “technically correct” outputs that still feel wrong. Design Arena exists because there hasn’t been a standard way to pressure-test taste, usability, and aesthetics at scale. No benchmark → no consistent feedback loop → slow improvement. --- ## Traction Design Arena gained significant early adoption, drawing tens of thousands of users across well over a hundred countries within weeks of launch, and later expanding to well over a hundred thousand users worldwide. --- ## Mission & posture Arcada’s posture is refreshingly direct: * Build grounded, real-user evaluation instead of vibes and anecdotes * Make the benchmark public so progress is visible (and comparable) * Use the leaderboard as a mirror that reveals limitations, not a trophy case Design Arena also presents a strong “access” stance: tomorrow’s creative evaluation tools should be broadly available, not gated behind enterprise walls. --- ## Team Arcada Labs is led by a small founding team with deep technical roots and a shared background, including experience building at Apple. Public-facing leadership includes: * **Grace Li (CEO)** * **Kamryn Ohly (CTO)** --- ## Funding & company status Arcada Labs is a 2025-founded company, backed by an accelerator/incubator round, and associated with Y Combinator. --- ## Contact Arcada maintains a founder-facing contact channel for leaderboard nominations, partnerships, and community collaboration.
