Durability Ranking: Consumer Internet and Adtech

The headline numbers

Of the 108 consumer internet and adtech companies in WillItSurvive's July 2026 assessment, only 6 earned the top standing of hard to displace, while 68 were rated losing its protection. The category carried elevated pressure overall as of the July 2026 assessment, with 32 of the 108 companies flagged as facing high competitive pressure. That makes this one of the more stressed verticals in the assessment of 10,525 companies.

The rest of the distribution, from the same July 2026 assessment: 21 companies rated protection under test, 9 rated little protection left, 6 defensible for now, and 7 with insufficient evidence for a standing.

We never declare an outcome for any company. What follows is what the evidence showed as of July 2026, and dated things a reader can verify.

The split: pipes and data versus fee-based middlemen

The sector is dividing into two very different worlds. On one side sit companies that own the pipes, the retail data, or the identity graph. On the other sit intermediaries whose product was analysis, bidding, or measurement that hyperscalers now bundle natively.

The 6 built-to-last names in the July 2026 assessment were Alphabet, Amazon Advertising, LinkedIn, Klaviyo, and Magnite (Alphabet appears with two assessment records, both rated hard to displace). Each owns something buyers cannot easily replicate:

Alphabet holds Search, YouTube, and Cloud at a scale AI challengers have not matched, even as Perplexity and ChatGPT pull some queries away and Google's own AI Overviews cuts publisher referral revenue tied to AdSense.
Amazon Advertising sits on actual purchase data and a retail media position, with no meaningful customer loss visible in the July 2026 evidence, one of the least pressured names in the category.
LinkedIn has a professional graph of 1.3 billion members that AI recruiting tools still depend on rather than replace.
Klaviyo showed deep ecommerce workflow integration and no visible customer defection in the July 2026 assessment, placing it among the least pressured names in the category.
Magnite holds an independent position connecting streaming and CTV publishers to buyers, and was growing while rival PubMatic shrank in the same space.

Where the pressure is landing

The assessment mapped specific pressure lines, all as of July 2026:

The Trade Desk vs. Amazon. The Trade Desk was rated losing its protection in the July 2026 assessment because Amazon's DSP bundles Prime Video and retail data at close to a 1% take rate against The Trade Desk's roughly 21.6%. That gap is the single clearest fee-compression story in the vertical.

Digital Turbine vs. AppLovin. AppLovin's Axon bidding engine was reported winning mobile ad mediation share of around 61% on iOS and 40% on Android as of the July 2026 assessment, at the expense of Digital Turbine's AGP and DTX products. Digital Turbine was rated losing its protection in the assessment, as was AppLovin itself, though AppLovin faces a funded coalition around AppsFlyer and an SEC probe of its data practices.

Xandr vs. its own parent. Microsoft is retiring Xandr's Invest DSP in favor of Copilot-based buying, pushing demand-side spend toward The Trade Desk, Google DV360, and Amazon Publisher Services. Xandr was rated protection under test in the July 2026 assessment, among the more pressured names in the category.

Criteo and the native-ad players. Criteo is seeing its core retargeting business absorbed as brands shift spend into Google Performance Max and Meta Advantage+, and was rated losing its protection in the July 2026 assessment. Outbrain, also rated losing its protection and among the more pressured names in the assessment, is squeezed from both ends: AI Overviews cuts the publisher pageviews native ads depend on, while Taboola, Google, and Amazon fight for the same CTV budgets.

PubMatic. Rated losing its protection, pressured by Magnite's growth and by The Trade Desk's OpenPath, which lets publishers sell directly to buyers and skip exchange fees.

Regional squeezes: Japan and China

Japan's ad agency holding companies show a cluster of stress in the July 2026 data. Septeni Holdings, DAC Holdings, and Freakout Holdings were all rated protection under test, while Digital Holdings (Opt) was rated little protection left following its Hakuhodo DY buyout. These firms are being absorbed by their own parent networks while Google Performance Max and Meta Advantage+ let advertisers buy media directly.

China's ecosystem SaaS players face a parallel dynamic. Weimob and Youzan, both rated losing its protection in July 2026, are losing ground because ByteDance and Tencent are building merchant tools inside Douyin and WeChat that skip third parties entirely. Weimob's merchant-solutions revenue had already fallen 7.3% per the evidence in the July 2026 assessment. Cheetah Mobile (wide open in one assessment record, protection under test in a second) and iClick Interactive (wide open) round out the region's high-pressure names.

Sales and marketing SaaS: crowded and exposed

A large share of the 68 shaky-ground companies are marketing and sales-engagement SaaS: Outreach and Salesloft were both rated losing its protection as CRM giants build native AI competitors, alongside Highspot, Seismic, 6sense, Demandbase, Iterable, Attentive, ActiveCampaign, and many others across the same shaky-ground tier. Relative bright spots include Salesforce, Braze, Brevo, and MoEngage (all defensible for now), plus Customer.io, AppsFlyer, and StackAdapt (Protection under test). At the weak end, Yesware, Terminus, Mixmax, Marigold, Seamless.ai, and LeadIQ were all rated little protection left.

Why trust the method

In a backtest against 116 companies that later failed, the assessment considered only facts that were knowable 18 months before each company's collapse, compared against a matched set of survivors assessed on the same cutoff. It flagged the failed companies as high-risk in the large majority of cases and never once cleared a company for safety that turned out to be dead within 18 months. We do not claim to have predicted anything; the supported claim is that, given only pre-collapse facts, the assessment separated troubled companies from matched survivors and never once gave a clean bill of health to a company that was dead within 18 months.

Dated watch-items (verify these yourself)

By August 2027: whether Amazon's ad revenue growth outpaces The Trade Desk's reported quarterly revenue growth in at least two of four quarters, as the take-rate gap plays out.
By June 2027: whether AppLovin's mediation share moves beyond the reported 61% iOS and 40% Android figures while Digital Turbine's AGP/DTX revenue declines year over year.
By December 2027: whether another Japanese digital ad agency holding company is fully absorbed into a larger network, following Digital Holdings' Hakuhodo DY buyout.
Ongoing: publisher referral traffic from Google Search, which signals whether AI Overviews is structurally cutting the traffic base native ad networks depend on.

Questions this data answers

Which consumer internet and adtech companies rated strongest in July 2026? Of the 108 companies assessed in July 2026, only Alphabet, Amazon Advertising, LinkedIn, Klaviyo, and Magnite earned the hard to displace standing. Each controls first-party data, distribution, or an identity graph that buyers cannot easily replicate, and none showed visible customer loss in the July 2026 evidence.

Is The Trade Desk losing ground to Amazon? As of July 2026 The Trade Desk was rated losing its protection. Amazon's DSP bundles Prime Video and retail data at close to a 1% take rate versus The Trade Desk's roughly 21.6%, and the watch-item to check by August 2027 is whether Amazon's ad growth outpaces The Trade Desk's in at least two of four quarters.

Are Japanese ad agencies under structural pressure? Yes, per the July 2026 assessment. Septeni, DAC, and Freakout were rated protection under test and Digital Holdings wide open, squeezed by parent networks like Dentsu and Hakuhodo DY absorbing them and by Google Performance Max and Meta Advantage+ letting advertisers buy directly.

How does Klaviyo compare to other marketing SaaS? Klaviyo showed no visible customer loss in the July 2026 assessment and was rated hard to displace, one of the strongest standings in the 108-company category. Peers like Outreach and Salesloft were rated losing its protection as CRM incumbents build native AI competitors.

Is Xandr shutting down? No, but per the July 2026 evidence Microsoft is retiring Xandr's Invest DSP in favor of Copilot-based buying. Xandr was rated protection under test in the assessment, and the shift directs demand-side spend toward The Trade Desk, Google DV360, and Amazon Publisher Services.
