Approxima

YCombinator

Your software should build itself.

Human-assisted development should be for novel ideation, not routine maintenance, bug fixes or incremental updates. Approxima is bringing you that future with agents that can scope work, code, validate their fixes end-to-end in sandbox environments and merge to production.

AquaShield

YCombinator

AI water leak detection for buildings

AquaShield protects large real estate portfolios against water damage (losses of up to hundreds of millions per year).

Ara

YCombinator

The Cloud Coding Agent

Ara is the cloud coding agent — an autonomous software engineer for software teams. It watches work in progress, plans the next step, and executes tasks with its own computer, background agents, persistent memory, and reusable skills. Unite your team that uses Claude and Codex and other coding subscriptions to code together in the browser. Ara turns coding into a closed loop: suggest, act, learn, improve.

ARC Prize Foundation

YCombinator

AI benchmarks that measure general intelligence and inspire new ideas

ARC Prize builds AI benchmarks that measure general intelligence. Our benchmark, ARC-AGI, has been used by OpenAI, Anthropic, Google DeepMind, and xAI. Founded by Mike Knoop and Francois Chollet, we inspire open source artificial general intelligence (AGI) research through benchmarks (the ARC-AGI series), global competitions, research grants, community, and content, we exist to guide researchers, industry, and regulators on the path to AGI. We believe that AGI requires more than just scaling up existing AI models. It demands a fundamental shift towards systems capable of genuine fluid intelligence, the ability to adapt to novel challenges and solve problems efficiently, much like humans do.

Archal

YCombinator

The improvement loop for AI agents

Modern AI agents can send emails, change code repos, and talk with external APIs. Archal verifies your agent takes the right actions, and opens a fix PR when it doesn't.

Archer

YCombinator

Global payouts for the workforce powering AI

Archer is the financial infrastructure for the AI data economy. We’re building global payouts, stablecoin banking, and yield infrastructure for the companies supplying data to frontier AI labs. As demand for high-quality data grows, millions of contributors around the world are generating, labeling, validating, and improving the datasets that power modern AI systems. Yet the financial infrastructure behind these platforms remains slow, fragmented, and expensive. Archer enables data marketplaces, AI labor platforms, and reinforcement learning environment providers to onboard workers globally, pay contributors instantly, and earn yield on idle balances. Today, companies use Archer to manage contributor earnings, global payouts, and treasury operations across hundreds of countries and payment corridors. We believe the next generation of AI companies will need purpose-built financial infrastructure. Just as cloud providers became the backbone of software, Archer is building the financial layer for the global workforce powering artificial intelligence.

Arctic Health

YCombinator

AI-native credentialing and contracting for healthcare

Arctic Health is building AI-native credentialing and contracting for healthcare organizations. We automate the full workflow, from establishing payer contracts to enrolling each provider. We collect and validate organization and provider data according to each state and payer’s requirements, and submit on the organization's behalf. We then monitor status and compliance on an ongoing basis. Tools on the market today either perform small pieces of the workflow or price out small and mid-sized organizations. We handle the process end-to-end regardless of organization type or size. Our browser automations enable AI agents to submit and monitor across hundreds of payer portals, and our system is trained by experienced industry experts who handle every edge case. Healthcare organizations get one simple platform. We handle the rest.

Arden

YCombinator

AI-native internal audit firm

Arden is the AI-native platform for internal audit and SOX teams. We build AI agents that automatically pull evidence from your stack, test controls end-to-end, and produce audit-ready workpapers in minutes instead of weeks. Internal audit is a massive but underserved market. Every public company in the US is required to do SOX testing, yet teams still run it through spreadsheets and screenshots. Arden is the engine that does this work.
