Nicole Atack is a British-educated technologist and entrepreneur who is the co-founder and chief technology officer (CTO) of Yarn, an artificial intelligence company that enables users to create sales and marketing videos. Yarn participated in Y Combinator's Winter 2024 batch.

Early life and education

Atack studied at the University of Cambridge, where she earned a BA and MSci in Experimental and Theoretical Physics between 2006 and 2010. Prior to founding Yarn, she worked as a quantitative analyst and particle physicist.

Career

Atack co-founded Yarn in 2023 alongside Jasper Story, who serves as the company's CEO. The company is headquartered in New York and operates in the business-to-business (B2B) space, focusing on AI-powered video creation for sales and marketing teams.

Yarn's platform allows founders, salespeople, and marketers to produce professional-quality product videos, sales collateral, launch videos, use-case demonstrations, training guides, and feature update content for platforms such as Twitter and LinkedIn. The company positions its output quality as comparable to that of well-known technology brands such as Notion, Linear, and Stripe, while requiring no prior video editing experience from users.

The platform incorporates several AI technologies, including text-to-speech (TTS), computer vision (CV), and large language models (LLMs), which the company says enable users to produce videos approximately five times faster than screen-recording tools such as Loom. Key features include a "part-synthetic talking head" capability that blends real and AI-generated footage, allowing users to reuse or generate new talking head clips without reshooting. The platform also offers automated product demo editing, generative brand overlays, caption generation, eye contact correction, and studio-quality voice processing.

Yarn's clients include startup teams using the tool to scale content production. Varun Anand, co-founder of Clay, has been cited as a user of the platform.

As CTO, Atack is responsible for the technical development of Yarn's AI-driven video production tools. Her background in quantitative analysis and physics informs the company's approach to applying computational methods to video creation. Yarn was supported by Y Combinator group partner Pete Koomen during the W24 batch.
