The startup, led by Kleiner Perkins, is constructing inference infrastructure specifically designed for AI agents that run for hours, not seconds, across thousands of simultaneous tasks.\n\n## What Sail Research actually builds\n\nThe company was co-founded by Neil Movva and Samir Menon. Movva’s resume includes stints at NVIDIA, Apple, and Together AI. He also previously co-founded Blyss, an encrypted AI platform built on advanced secure computing methodologies.\n\nSail’s core product combines high-efficiency open-source model serving with what the company calls “Sailboxes,” persistent sandboxed environments designed to keep AI agents running continuously in the cloud. The Sailboxes support OpenAI-compatible APIs. According to the company, its platform delivers performance that is 12 times more cost-efficient compared to proprietary systems. Sail claims to have already processed trillions of tokens, with applications spanning cybersecurity analysis and automated code review.\n\nKleiner Perkins partner Aditya Naganath had been developing a thesis around this exact gap in the market before meeting Movva.\n\n“It felt obvious to both of us that you’re going to need a different, specific inference platform built for these long-running agents,” Naganath told Fortune.\n\n## What this means for investors\n\nSail’s $80 million raise, combining both seed and Series A capital, represents the kind of concentrated early-stage bet that Kleiner Perkins typically reserves for companies it views as category-defining. Sail launched Sailboxes in April 2026 and is already processing trillions of tokens.\n\nSail itself has no direct connection to crypto tokens. There’s no token launch, no blockchain component, no DePIN angle in its current product. But the technical problems it’s solving, efficient inference, persistent compute environments, secure sandboxing, map onto the challenges facing decentralized AI infrastructure projects such as Akash, Render, and io.net.\n\nSail’s 12x cost-efficiency claim, if it holds up in production environments, represents a potential economic advantage in deployment. Decentralized compute networks will need to demonstrate comparable performance benchmarks if they want to compete for the same workloads.\n\n**Disclosure:** This article was edited by Editorial Team.
