Vibe.co secures $50M Series B to accelerate AI-powered CTV advertising expansion

Vibe.co has raised $50 million in a new Series B funding round led by investment firm Hedosophia, bringing its valuation to $410 million. Previous backers Elaia and Singular also participated, along with new investors including QuantumLight (backed by Revolut CEO Nik Storonsky), Illusian (led by Supercell’s CEO), and angel contributors such as Carolyn Everson. As part of this expansion, Nextdoor CEO Nirav Tolia joins Vibe.co’s board of directors.

The fresh capital arrives a year after Vibe.co closed its Series A round of $22.5 million — a move that bolstered its early growth and helped the company scale its self-serve CTV ad infrastructure.

Since then, Vibe.co claims it has achieved a revenue run rate of $100 million, reached over 120 million households across 500 streaming apps and channels, and expects to reach profitability by the end of 2025. It positions itself as the lone self-serve ad platform in the U.S. focused on delivering performance marketing tools for connected TV.

With streaming now accounting for nearly 45% of U.S. TV viewership and digital video ad spend outpacing overall media growth, Vibe.co aims to address the fragmentation and opacity that have long challenged the ad landscape. The company’s platform is built on combining media buying, creative tools, and AI-driven optimization in a unified solution.

A key component is Vibe Studio, its AI-powered creative editor. Vibe.co reports that around 10% of the ads running on its platform are already AI-generated, and it expects that share to rise to over 30% by 2026. The new funding will also support enhancements to generative and agentic AI tools, deeper integration with streaming publishers, and improved yield management capabilities for publishers.

By bridging audience behavioral and purchase intent signals with premium CTV inventory, Vibe.co aims to enhance targeting precision. Its recommendation system seeks to match specific products to individual viewers — a model the startup claims outperforms traditional TV segments by as much as fourfold.

As the company scales, the additional capital will be deployed to strengthen streaming partner integrations and expand its measurement infrastructure — an essential factor as marketers increasingly demand proof of sales lift and return.
