Computer-use agent evaluationmarket profile
- text: Computer-use model evaluation benefits from real user tasks and blind preference comparisons, beyond static benchmark scores.
- text: The product has a two-sided audience: people submit tasks and judge results, while AI labs can use evaluation and training data.
personas
- title: AI evaluation or model research leadpains:
- Static benchmarks may not reflect real user workflows
- Collecting independent comparisons across competing agents is expensive
- title: AI product or agent engineering leadpains:
- Selecting a model for computer and phone tasks without comparable real-world evidence
- Testing model capabilities across diverse tasks and failure modes
- title: AI-curious end userpains:
- Comparing model performance without building separate integrations
- Finding out whether an agent can complete an actual task
icp
- text: Frontier model labs and agent builders evaluating or training computer-use systems, with a need for human preference data.
- text: Developers and product teams choosing between AI models for browser, desktop or phone workflows.
message pillars
- text: Test frontier models on tasks that matter to users.
- text: Agents operate on actual device interfaces.
- text: Make multiple models accessible through one API.
objections
- objection: Are rankings independent if the operator also builds an agent?response: Review governance, blind comparison methodology and model-level sample sizes before relying on rankings.
- objection: Does a leaderboard score predict our use case?response: Compare relevant task categories and validate on your own workflows, since aggregate preferences may not match local needs.
- objection: What happens to task data or credentials?response: Review the current privacy, security and saved credential terms before submitting sensitive tasks.

- name: Prateek Jannutitle: Founder/CEOrole: CEObio: Prateek Jannu, Co-founder & CEO - Stanford (MS. EE) and Purdue (BE. CE). Invented Solo-Synth-GAN, which generates labeled training data from a single example. Built Coasty to #1 on the OSWorld benchmark (82%), beating Agent S3, UiPath, Kimi K2.5, and Claude Sonnet 4.5. Now building CoArena.
- name: Nitish Kovurutitle: Founderrole: Founderbio: Co-founder and CTO/COO of Coarena, launched Coasty prev, SOTA CUA framework on OSWorld at 83% accuracy. Did CS at Columbia (Vision track) and hold a BS in Computer Engineering from Purdue, where I TA'd a graduate-level AI course as an undergrad and later went on to build enterprise sales automation agentic systems for my previous company.
