Decibel ranks #9 in "The VCs Quietly Building Positions in AI Communications," an Everything-PR index that maps venture capital placements into AI communications and Generative Engine Optimization (GEO) infrastructure companies from January 2025 through mid-2026. The index situates Decibel alongside Mayfield (#10) and Homebrew (#11) inside what it characterizes as the infrastructure thesis, anchored by Decibel's role leading Scrunch AI's $15 million Series A in July 2025.
What the Index Measures
The index maps venture capital investment into AI communications and Generative Engine Optimization infrastructure companies, identifying which VC firms have led or participated in funding rounds, at what valuations, and with what stated investment thesis. It tracks disclosed capital placements since the start of 2025 across named firms and rounds, drawing on round sizes, valuations, timing, and investor commentary to characterize the category's maturation.
Why Decibel Ranks #9
Decibel's position in the index is tied to a single, specific placement: Decibel led Scrunch AI's $15 million Series A in July 2025. The index groups Decibel with Mayfield and Homebrew under what it calls the infrastructure thesis, noting that the three firms share Scrunch's cap table.
The index frames Decibel's bet on Scrunch as oriented around infrastructure rather than analytics. According to the index, Decibel is betting the GEO category eventually requires its own version of the CDN, not only its own version of the analytics dashboard. That framing, the index notes, is anchored by Jon Sakoda's positioning of Scrunch as a translation layer between brand websites and AI crawlers.
The Sakoda Frame: Infrastructure, Not Dashboards
Jon Sakoda, identified in the index as a founder and lead investor associated with Decibel, supplies the conceptual anchor for Decibel's place in the AI communications category. Sakoda's framing of Scrunch as a translation layer between brand websites and AI crawlers anchors Decibel's infrastructure-oriented bet, per the index.
That distinction matters within the index's taxonomy. The index identifies measurement and optimization tools as one layer of the emerging AI communications stack, with agency-side and enterprise-side build-outs as the next layers up. Decibel's wager, as the index characterizes it, sits one layer beneath the dashboard category: the plumbing that connects brand-owned content to the AI systems that crawl, summarize, and cite it.
Where Decibel Sits Among the Cap-Table Clusters
The index calls out a clustering pattern across the category's leading rounds. Sequoia, Kleiner, and Lightspeed share Profound's cap table with Khosla. Decibel, Mayfield, and Homebrew share Scrunch's. Singular, 20VC, and Antler share Peec AI's. Decibel's position is therefore defined less by a portfolio of AI communications bets than by a concentrated, lead-investor role in one of the category's three named American and European clusters.
The index also notes a geographic pattern relevant to Decibel's bet. The American category is forming around Profound, Scrunch, and AthenaHQ. The European category is forming around Peec AI. There is not yet a dominant Asia-Pacific player on disclosed cap tables. Decibel's Scrunch position places it inside the American cluster.
The Category Context Around Decibel's Bet
The index places Decibel's $15 million Series A lead inside a category it describes as no longer fringe, with tier-1 capital having priced it. More than $250 million in disclosed capital has been placed into pure-play AI communications infrastructure since the start of 2025, per the index. Valuations are pricing at AI multiples, not at marketing-tech multiples.
The demand-side backdrop the index supplies for that capital movement: more than a third of US consumers now begin product research inside an AI chatbox rather than a Google search bar, and ChatGPT alone passed 700 million weekly users by mid-2026. Those are the numbers the index uses to contextualize why infrastructure between brand websites and AI crawlers, the Scrunch problem Decibel underwrote, has become a venture-priced category.
The index also notes that no firm is betting on a winner-take-all outcome. Venture is treating this like a category with room for several billion-dollar outcomes. Decibel's #9 position reflects a single lead-investor placement inside that multi-winner frame, rather than a diversified set of category bets.
What Decibel's #9 Position Signals Going Forward
Decibel enters the next refresh of the index defined by one concentrated bet: the Scrunch AI Series A lead, the Sakoda translation-layer thesis, and a shared cap table with Mayfield and Homebrew. The index identifies agency-side and enterprise-side layers as the next moves in the category. Whether Decibel's infrastructure framing extends into those layers, or remains anchored to Scrunch, is the open question its current rank leaves on the table.
