John
Kremer

At Cornell, John Kremer was co-captain of the varsity tennis team - the kind of role that tells you something about how he operates. Not just a player. The one who holds the team together. Thirty years later, he is doing the same thing at Rizzle, a company trying to solve one of media's most persistent problems: publishers know words, and audiences increasingly demand video.

Rizzle's answer is AI-powered video creation at industrial scale. A news article goes in. A broadcast-quality video comes out. The time from draft to distribution collapses from days to minutes. Costs drop by 80%. The platform reaches over a billion viewers a month across MSN, Yahoo, NewsBreak, and a constellation of social platforms. These are not projections. These are numbers from a company that has been quietly shipping while everyone else was writing blog posts about the future of media.

Kremer came to Rizzle with the kind of background that makes board decks look good but tells you something more interesting: he has run enormous, complex platforms under genuine pressure. As VP and GM of Yahoo! Mail, he managed what was then the world's largest email platform. Then he spent time as Chief of Staff to not one but three consecutive CEOs at Yahoo! - a feat of institutional endurance that requires reading rooms, managing competing agendas, and staying useful through radical changes in direction. Yahoo! in that era was not a calm place.

After Yahoo!, Kremer moved to JP Morgan Chase as Senior Vice President and Product Leader for Chase.com and its digital banking experiences. The shift from consumer internet to financial infrastructure is not an obvious one. But the underlying skill - taking something vast and complex and making it work for millions of users - translated cleanly. Then came Adobe.

His seven-year run at Adobe is the chapter that most investors in Rizzle probably spent the most time studying. He joined as VP of Business Development and Operations and Chief of Staff for the Digital Media organization. When he arrived, that business was under $3 billion in annual revenue. By the time he left, it had crossed $12 billion. This is not a market tailwind story. Creative Cloud's growth required relentless operational discipline, strategic partnership development, and the kind of cross-functional coordination that only works when someone is running it who knows both the product and the business side with equal fluency.

The obvious question is: after Yahoo! Mail, after Adobe's digital media empire, after JP Morgan Chase - why build video infrastructure for publishers? The answer is that Kremer spotted the gap that everyone in media was failing to close. Newsrooms and digital publishers have editorial muscle and distribution networks. What they lack is the ability to produce video at scale. Video is expensive, slow, and requires skills most editorial teams simply do not have. Rizzle removes every one of those constraints simultaneously.

He joined the company as CEO in the early 2020s and has been steering it from a short-video app toward a full-stack video infrastructure play for media companies. The pivot is complete. The clients now include BC Media Group, The Publisher Desk, ImpreMedia, and Nordot. The distribution reaches MSN and Yahoo - audiences that most publishers spend years trying to access. Rizzle is their on-ramp.

Founded in 2019, Rizzle started as a short-video platform - a timeline that intersects uncomfortably with TikTok's explosive rise. But Rizzle did something most competitors in that space did not: it recognized that the consumer short-video war was unwinnable for a startup, and the more defensible opportunity was infrastructure. Publishers needed video. Publishers did not know how to make video. Rizzle could build the bridge.

The core product converts written content - articles, newsletters, blogs, podcasts - into short and long-form video using AI. But "converts" undersells it. The platform handles script generation, visual selection, voiceover, brand customization, distribution, and analytics. A publisher's article enters the system; a video tailored to their brand guidelines and optimized for their target distribution channels comes out the other end. The recently launched Podcast-to-Video feature extends the same logic: audio becomes watchable video without a human editor touching anything.

The Text-to-Map feature is worth a mention on its own. Choropleth maps - the kind data journalists use to visualize geographic stories - are notoriously time-consuming to create. Rizzle can now generate them from text prompts. For a newsroom covering regional election results or demographic data, this is not a convenience feature. It is a capability that did not exist before.

The distribution side of the business is what separates Rizzle from AI video tools that produce content and stop there. Rizzle's syndication network reaches over a billion viewers monthly, through partnerships with MSN, Yahoo, NewsBreak, and social platforms. Publishers are not just making videos - they are getting those videos in front of audiences at a scale most editorial teams could never achieve independently. Content to distribution in one platform, with Getty Images integration for licensed media assets already cleared for publication.

The resume is all Silicon Valley pedigree and impressive revenue numbers. But Kremer also coaches tennis at Castilleja School in the Bay Area - a role that has nothing to do with building software companies and everything to do with how he thinks about development, competition, and performance under pressure. The sport that made him co-captain at Cornell never quite left.

He lives in Menlo Park with his wife and three sons - an arrangement that puts him squarely in the culture of the Valley while keeping him grounded in the kind of ordinary family life that sharpens perspective. Three sons tends to do that.

The founding partner role at NosTerra Ventures runs parallel to his CEO duties at Rizzle. It is not a title of convenience. It reflects a genuine conviction that experience compounds and that the operators who have seen what actually works inside large platforms have something specific to offer founders who are trying to build them. The venture portfolio is an extension of the same instinct that drives Rizzle: find the infrastructure gaps, and fill them.

There is a consistency in the career that is easy to miss because it spans so many different organizations. Yahoo!, Adobe, JP Morgan Chase, Rizzle - these look like a diverse portfolio of experiences. But the through-line is always the same: large, complex platforms used by millions of people, with operational, business development, and strategic challenges that require someone who can move between the product and the business side with equal fluency. Kremer has been that person, at every stop, for thirty years.
