Founders Fund, Pantera, and Franklin Templeton join Sentient's "Arena" to stress test enterprise-level AI agents

In the past two years, companies have been accelerating the integration of AI agents into real workflows: from customer service and backend operations to finance and compliance processes that require high-stakes decision-making. As these systems are increasingly embedded in actual business operations, a new issue is emerging: while agents can retrieve information, they often struggle to provide stable, interpretable, and reproducible reasoning processes when work becomes "messy," multi-step, or high-risk.

Today, the open-source AI lab Sentient officially launched Arena—a real-time, production-ready environment for thousands of AI developers worldwide to stress-test and iteratively compete on the toughest reasoning problems faced by enterprises. The initial lineup of participants in Arena's first phase includes Founders Fund, Pantera, and Franklin Templeton, which manages over $15 trillion in assets—sending a signal that institutions are showing early, clear interest in "structured evaluations of AI agents before deployment."

"When companies apply AI agents to research, operations, and customer-facing workflows, the question is no longer whether these systems are powerful enough... but whether they are reliable in real workflows," said Julian Love, Managing Partner at Franklin Templeton Digital Assets. Love added that structured environments like Arena will help the industry distinguish between "promising ideas" and "capabilities that can truly be used in production."

Sentient co-founder Himanshu Tyagi stated, "AI agents are no longer just experiments within companies; they are entering critical processes that touch customers, funding, and operational outcomes. This shift changes the criteria for evaluation. It's not enough for systems to look impressive in demos. Companies need to know: in production environments, where the cost of failure is high and trust is fragile, can agents still reason reliably? Businesses need comparability, repeatability, and a method to track reliability improvements over the long term that does not depend on the underlying model or tool stack."

Arena simulates the real chaos of enterprise workflows: incomplete information, lengthy context, vague instructions, and conflicting sources. Arena does not just assess whether agents provide "correct answers," but records complete reasoning traces so engineering teams can pinpoint failure causes and validate improvements over time.

This provides a neutral, vendor-agnostic benchmark for reasoning evaluation across models and technology stacks. Arena emphasizes production-level performance rather than demo performance, thereby forming verifiable agent capabilities applicable to high-risk scenarios, which businesses can also transfer to their private data and internal tools.

In the first challenge, developers joining Arena will focus on an enterprise-level foundational problem: document reasoning. AI agents need to reason and compute over complex, unstructured data—this type of work underpins scenarios such as financial analysis, root cause investigation, investment memo writing, and customer service.

Other participants in the initial phase include alphaXiv, Fireworks, OpenHands, and OpenRouter; as Arena expands in tasks, industries, and model integrations, more participants are expected to join.

Recent research also highlights the gap that Arena aims to address: 85% of companies express a desire to become "agentic enterprises," with nearly three-quarters planning to deploy autonomous agents, but fewer than a quarter actually have mature governance systems; many companies struggle to scale pilot projects to large-scale production deployments. On average, companies are running about a dozen agents, often scattered across isolated scenarios; many believe that without better orchestration and collaboration capabilities, adding more agents will only increase complexity and decrease value.

"At OpenHands, we have always been eager to support developers in using agents to solve real, practical problems," said Graham Neubig, Chief Scientist and Co-founder of OpenHands. "We are also excited to support participants in using the OpenHands Software Agent SDK to tackle these complex challenges."

Alex Atallah, Co-founder and CEO of OpenRouter, stated, "Arena is exactly the kind of initiative that can push open-source AI forward—it allows researchers to compete, iterate, and innovate in an open environment. We look forward to deepening our collaboration with Sentient and providing the infrastructure to make experiments faster and easier to scale."

Arena will launch globally, inviting thousands of AI developers to apply for the first limited cohort, with offline events scheduled to take place in San Francisco starting March 2026.
