GumGum

Contextual advertising across web, CTV, games

Overview

GumGum is a digital advertising company that uses contextual advertising to reach audiences. It places ads based on the content people are viewing instead of tracking individual user data, across websites, mobile apps, connected TV, and in-game environments. The core product is a contextual advertising platform that analyzes the surrounding content to select relevant ad placements and deliver ads in the right environment. Advertisers pay GumGum for these services, while publishers can increase their revenue by hosting the contextual ads. GumGum differentiates itself by focusing on privacy-friendly contextual targeting, offering education through GumGum University, and specializing in in-game and connected TV placements in addition to standard digital media. The company’s goal is to help brands reach the right audience at the right time without using personal data, while growing revenue for publishers and expanding adoption of their contextual approach.

Simplify's Take

What believers are saying

  • July 2026 Mindset Agent launch shortens briefing-to-activation time for agencies and advertisers.
  • Heineken, e.l.f. Beauty, and the BBC provide credible early proof points for adoption.
  • 2026 leadership additions in Japan, Northern Europe, and Australia show active international expansion.

What critics are saying

GumGum launches AI 'Mindset Agent' for advertisers.

GumGum launches AI 'Mindset Agent' for advertisers. Published on: 16th July 2026 at 10:21 AM Advertising technology company GumGum has launched a new AI-powered tool designed to help advertisers turn campaign briefs into custom audience segments, with activation initially available through The Trade Desk. Called Mindset Agent, the platform sits within GumGum's newly redesigned Mindset Portal and uses the company's proprietary Mindset Graph to analyse campaign objectives and recommend contextual targeting segments based on audience receptivity rather than traditional demographic or behavioural signals. The launch marks an expansion of GumGum's longstanding partnership with The Trade Desk. While GumGum's contextual segments have been available on the demand-side platform for several years, advertisers can now generate and activate bespoke mindset segments directly from campaign briefs. Using the tool, brands and agencies can upload a campaign brief or RFP into the Mindset Portal, review AI-generated targeting recommendations, understand why specific environments have been selected, refine the balance between reach and relevance, and activate the custom segment within The Trade Desk. According to GumGum, the platform aims to streamline what has traditionally been a manual process by using AI to match advertising campaigns with moments when consumers are most receptive to a brand's message. The technology is powered by GumGum's Mindset Graph, which processes billions of contextual, creative, attention, environmental and historical signals to identify digital environments that align with an advertiser's objectives. Jay Goebel, vice president of data partnerships at The Trade Desk, said AI was enabling advertisers to make more intelligent media decisions. "AI is creating an opportunity for advertisers to move beyond static assumptions and make decisions based on real-time signals and business objectives," Goebel said. "By combining GumGum's Mindset Graph with our data marketplace, advertisers can transform campaign strategy into actionable insights and identify the moments where their message is most likely to resonate." Marcus Startzel, CEO of GumGum, said the company wanted AI to improve decision-making rather than simply automate existing targeting approaches. "AI should not just automate old targeting models. It should help brands make better decisions about where, when, and how to show up," Startzel said. "This partnership with The Trade Desk brings that belief to life by making it easier for advertisers to turn strategic intent into custom mindset segments that prioritise receptivity, not just reach." Daniel Glynn, media buying lead at The HEINEKEN Company, an early adopter of the technology, said understanding audience mindset offered a more meaningful approach to relevance. "Understanding mindset, the signals that indicate when and why someone is actually open to a brand's message, is a more honest way to think about relevance, and AI is finally making it actionable at scale," Glynn said. Alongside Heineken, GumGum said e.l.f. Cosmetics and the BBC have also begun using its mindset solutions and have reported measurable campaign results. The Mindset Agent is now available through the Mindset Portal, with The Trade Desk serving as its launch activation partner.

GumGum appoints Tim Manton to lead NSW & QLD sales

GumGum appoints Tim Manton to lead NSW & QLD sales. GumGum has appointed Tim Manton as Sales Director for New South Wales and Queensland, adding a senior sales lead across two of Australia's largest advertising markets. Manton will lead the company's NSW and QLD sales teams. The remit includes talent development, revenue growth, and work with agencies and clients. GumGum said Manton will focus on attention-driven advertising as brands adjust measurement approaches. The company said Manton will work with GumGum Australia Managing Director Matt Coote on local execution. Manton will also work with customer success and engineering teams on market feedback and product direction. GumGum said it will align local activity with global leadership and its "mindset-based approach". Manton has more than 13 years' experience across media and advertising in Australia. GumGum said his experience spans video, audio, digital publishing and marketing technology. He most recently worked at Seven West Media. The company said he served as Group Business Director and managed a $200M+ portfolio. GumGum also said Manton drove growth through omni-channel partnerships in that role. Before Seven West Media, Manton held roles at Paramount, SCA and Nine. GumGum said he built relationships with major agency holding groups and independent agencies during his previous positions. GumGum said Manton will scale the NSW and QLD teams and focus on partnerships with agencies. The company also cited an initial "listen-first" approach with agency partners and plans to replicate strategies used in other Australian markets. "At GumGum, the opportunity is massive," said Tim Manton, Sales Director for NSW and QLD, GumGum. "My focus is on backing our high-performing sales teams across New South Wales and Queensland and making sure we're set up to deliver real value for agency and client partners. I'm a big believer in leading from the front, so I'll be taking a player-coach approach to ensure our strategy translates into results on the ground as we scale into 2026," he added. The role sits within GumGum's Australian operation, which forms part of a wider international footprint. The company said it operates in more than 19 markets across North America, Europe, Japan, and Australia. GumGum describes itself as a contextual-first advertising company. It said its product approach links advertising to "mindset" and uses a data engine called the Mindset Graph. GumGum said the Mindset Graph processes contextual, creative, environmental and historical signals in real time. The company said it uses those signals to decide which ad to place against an audience at a given moment. It said this makes advertising "more relevant for consumers". It also said the approach drives outcomes for advertisers and publishers. The appointment comes as advertising and media companies invest in alternatives to established audience tracking and measurement approaches. Contextual advertising has drawn attention in markets where platform and browser changes have reduced access to identifiers and user-level data. Manton will work closely with Coote in the role. "Tim brings a strong combination of commercial leadership, deep market experience and a people-first management style. His background across major publishers and his collaborative approach make him a great addition to the team as we continue to grow GumGum's presence in Australia," Coote said. GumGum said Manton will collaborate with customer success and engineering teams as part of the NSW and QLD leadership remit, while also coordinating with global leadership as the company expands its local presence.

e.l.f. Beauty Drives 3X Engagement with GumGum's Contextual AI in "So Many Dicks" Campaign

e.l.f. Beauty drives 3X engagement with GumGum's contextual AI in "so Many Dicks" Campaign. News provided by. Building on its viral "So Many Dicks" campaign, e.l.f. Beauty and their lead agency, Tinuiti, teamed up with GumGum, the contextual-first technology leader, to extend the message into 2025 as part of its broader "Change the Board Game" initiative. SANTA MONICA, Calif., Dec. 3, 2025 /PRNewswire-PRWeb/ - Building on its viral "So Many Dicks" campaign, e.l.f. Beauty and their lead agency, Tinuiti, teamed up with GumGum, the contextual-first technology leader, to extend the message into 2025 as part of its broader "Change the Board Game" initiative. The original campaign, which made waves for highlighting the disproportionate number of men named Dick on U.S. corporate boards compared to entire groups of underrepresented people, was reactivated through a display campaign strategically distributed through GumGum's AI-powered platform. The objective for the campaign was to influence corporate executives and board members in moments that matter. GumGum analyzed premium, brand-safe environments, targeting content categories such as Economy and Business & Finance, and content mentioning figures like Jeff Bezos and Bill Gates, to pinpoint audiences in the right mindset. The results were: * 16% engagement rate across the campaign (vs. 5.46% industry benchmark) * 67% greater interaction rate on top-performing units (vs. 20% benchmark) * 84% overall viewability (exceeding the 70% benchmark) * 0.80% CTR, outperforming the 0.62% industry average * 2.3 seconds average viewable attention time "Our goal wasn't to drive shock value. It was to get the right people talking and rethinking what leadership should look like," said Regine Fung, AVP, Global Paid Media at e.l.f. Beauty. "With GumGum, we were able to deliver this message in the moments that mattered most, reaching decision-makers where they already engage and fueling conversations that help 'change the board game' moving forward." Using GumGum's Mindset Graph(TM), a surprising insight was uncovered during the campaign: sports content showed a 53% boost in attention over the vertical average and delivered the highest CTR at 2.44%. This revelation unlocked a new channel for reaching top executives during major sports moments. Interactive and high-impact formats drove deep engagement, including In-Image Canvas ads, mobile quiz units, and Hang Time. GumGum's Creative Attention Tracker (CAT) revealed that the line "It's okay to be a Dick" in the creative consistently triggered the highest pause rates mid-scroll, providing concrete feedback on what resonated most with audiences. "This campaign didn't just make headlines, it made history. Our job was to ensure that boldness met the right moment, on the right screen, for the right decision-makers. That's the power of contextual with purpose - reaching consumers in the right mindset to engage with a brand's message," said Kerel Cooper, CMO at GumGum. About e.l.f. Beauty e.l.f.
