Keynes' $40M Fundraise Signals CTV's Shift to Performance Metrics

AUSTIN, Texas – March 25, 2026 – Keynes, an advertising technology firm specializing in Connected TV (CTV), has secured a $40 million minority investment from Volition Capital. The deal marks a significant bet on the maturation of the streaming television ad market, signaling a broader industry shift from brand awareness campaigns to performance-driven, measurable results.

The investment from the Boston-based growth equity firm is earmarked to accelerate Keynes' growth through technology innovation, enhanced data capabilities, and strategic hiring. This move comes as advertisers pour billions into CTV but struggle to prove return on investment amidst a fragmented and often opaque digital ecosystem.

The New Frontier of Television Advertising

The flow of advertising dollars from traditional linear television to Connected TV is no longer a trend; it is a fundamental market realignment. As consumers trade cable boxes for streaming apps, brands are following them. Projections show the CTV ad market expanding dramatically, with some forecasts predicting it will nearly double to $13.5 billion by 2029. With ad completion rates reportedly as high as 98%, the channel's potential for engagement is undeniable.

However, this rapid growth has created significant challenges. The landscape is a complex web of countless streaming platforms, devices, and ad-supported services. For years, this fragmentation made it difficult for marketers to run cohesive campaigns and, more importantly, to measure their direct impact on sales and business growth. CTV was often treated like its linear predecessor—a powerful tool for building brand awareness, but one where a direct line to ROI was elusive.

This measurement gap has been the primary hurdle preventing CTV from becoming a true performance marketing channel. Keynes, founded in 2018, was built to address this specific problem, positioning itself not just as another platform but as a partner for brands seeking accountability from their TV ad spend.

A Bet on Accountable Advertising

Keynes' strategy hinges on transforming CTV advertising from a cost center into a measurable growth driver. By combining an "audience-first" approach with AI-driven optimization and a commitment to transparent reporting, the company aims to prove the direct impact of streaming ads on business outcomes.

"We’ve always believed that sustainable growth comes from doing right by clients and building a strong internal culture," said Dan Larkman, Founder and CEO of Keynes, in a statement. "This partnership gives us the resources to move faster without compromising the principles that define Keynes, and we’re just getting started."

The platform's technology is designed to be "data agnostic," using machine learning to identify and target the most receptive audience segments across the fragmented CTV universe. This AI-powered optimization works in real-time to shift budget towards placements that are driving conversions, minimizing wasted spend. Crucially, Keynes layers this technology with a "high-touch services layer," providing advanced reporting that measures the holistic effect of a campaign, including its influence on other paid marketing channels. This addresses a major pain point for marketers trying to understand the full customer journey.

This focus on measurable outcomes is what attracted the attention of its new investors. "Connected TV is rapidly evolving from a brand-only channel into a measurable performance medium," noted Jim Ferry, a Partner at Volition Capital. "Keynes has built a differentiated platform that helps advertisers navigate the complexity of the ecosystem while delivering transparent, performance-oriented outcomes."

Navigating a Crowded and Competitive Market

Volition Capital's investment is a calculated move in the highly competitive ad-tech space. The firm, which specializes in high-growth, founder-led companies, saw specific strengths in Keynes' model. Ferry praised the company's "disciplined execution, strong client retention, and commitment to transparency," factors that signal a sustainable business model in a volatile industry.

Keynes operates in a market populated by giants. Major demand-side platforms like The Trade Desk and Google's DV360 offer massive scale and cross-channel capabilities. Device manufacturers like Roku leverage their platform dominance to control a significant portion of ad inventory. Meanwhile, specialized competitors like MNTN and Tatari are also focused on bringing performance metrics to television advertising.

Within this landscape, Keynes has carved out a niche as a specialized partner focused intently on performance. While larger platforms offer a buffet of services, Keynes' value proposition is its dedicated focus on solving the CTV measurement problem with a combination of sophisticated AI and strategic guidance. Its recent recognition as a finalist for "Most Innovative Advertising Partner" in the 2026 Digiday Video and TV Awards underscores the industry's acknowledgment of its unique approach.

The Strategic Power of a Minority Stake

The structure of the $40 million deal as a minority investment is itself strategic. Unlike a majority acquisition, this allows Keynes' founding leadership to retain control over the company's direction and culture. For a founder-led company like Keynes, this ensures that the vision and principles that led to its initial success remain intact. The investment acts as an accelerant, not a change in command.

The capital infusion will be deployed to deepen the company's technological infrastructure, expand data integrations, and scale its team. This will enable Keynes to enhance its core product and better serve the growing demand from medium-sized, enterprise, and high-growth brands seeking a clear return on their CTV advertising spend.

By backing a specialized, founder-led company, Volition Capital is betting that a focused, transparent solution will win in the long run. The investment validates the growing demand among advertisers for accountability and moves the entire CTV industry one step closer to fulfilling its promise as a fully measurable, high-impact marketing channel.
