Parasail

Parasail is a US-based AI inference cloud that sells access to large language and open-weight models rather than raw GPU-hours. Instead of owning campuses, it aggregates on-demand capacity from dozens of neocloud and colocation providers and routes workloads across that fleet through a single OpenAI-compatible API. Co-founder and CEO Mike Henry (previously Chief Product Officer at Groq and founder-CEO of Mythic) and co-founder Tim Harris (founder-CEO of Swift Navigation) launched the company in 2023, began engineering in early 2024, and came out of stealth in early 2025.

What differentiates Parasail from CoreWeave, Nebius, Crusoe and other capex-heavy neoclouds is that it never took the hyperscale infrastructure path. The company positions itself around what it calls the "token economy": customers commit to output (tokens served) on a fluid pool of Nvidia H100, H200, A100 and consumer 4090 GPUs sourced from partners, with dedicated deployments also available on newer parts including B300. That aggregator model let Parasail claim in April 2025 that its bookable on-demand fleet was larger than Oracle Cloud's, without Parasail itself owning any of it.

Parasail sits firmly on the inference side of the neocloud pack, aimed at AI-native startups rather than frontier training labs or Fortune 500 enterprise IT. Disclosed customers include Elicit, Weights and Biases, Rasa, MiniMax, Venice, mem0 and Skyfall AI. The company raised a $10 million seed in 2024 (Basis Set Ventures, Threshold Ventures, Buckley Ventures, Black Opal Ventures) and a reported $32 million follow-on round in April 2026, with Kindred Ventures, Touring Capital, Samsung Next and Banyan Ventures listed among backers.
