AI Startup Flapping Airplanes Raises $1 Billion at $6 Billion Valuation

WASHINGTON, Oct 21 (OPA) — Flapping Airplanes, a one-year-old artificial intelligence startup, announced Wednesday it raised $1 billion in a Series A funding round co-led by Index Ventures and Lux Capital. The investment marks a sharp increase in the company’s market value, which has quadrupled to $6 billion since its $180 million seed round nine months ago. Existing investors, including Sequoia, GV, and Kleiner Perkins, participated in the latest financing alongside new backers such as Nvidia, Valor, and Atreides.

The company was founded by Aidan Smith, Asher Spector, and Ben Spector. The founders are developing a "megakernel" framework designed to optimize GPU performance by overlapping memory-bound inference with compute-bound training. By bundling multiple tasks into a single program, the framework aims to reduce hardware idle time and increase efficiency. The founders claim this approach allows for the creation of intelligent systems without the need to ingest massive datasets typical of current large language models.

Before this round, the startup gained attention for its pedigree, with founders hailing from backgrounds at Neuralink and Stanford. Sequoia partner David Cahn previously described the venture as a "young person’s AGI lab," noting the founders' focus on talent and technical innovation. The company’s initial seed round, which valued the firm at $1.5 billion, was supported by GV, Sequoia, and Index, establishing a rapid trajectory for the early-stage enterprise.

With the new capital, the company plans to scale its operations and accelerate the development of its data-efficient AI architecture. The founders have stated that their primary goal is to lower the economic barriers to deploying advanced AI models. By increasing data efficiency by a factor of a million, they intend to make high-performance intelligent systems more accessible for broader economic integration.
