The intelligence and deployment layer for AI search
TAM // TOTAL ADDRESSABLE MARKET
SAM // SERVICEABLE ADDRESSABLE MARKET
Low confidence$1.4B to $2.2B
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
Real market, but the infrastructure layer is being consumed from both ends
The intelligence and deployment layer for AI search sits between two compressing forces: hyperscalers (OpenAI Responses API, Google Gemini Grounding, Azure AI Agents) bundling search natively into model platforms, and well-funded pure-plays (Glean at $610M raised, Exa at $250M Series C, Tavily acquired for $275M) locking up the API and enterprise retrieval wedges. Your weakest pitch moment will be the SOM path: at $40K ACV you need 550 enterprise logos in three years against incumbents who already have signed procurement relationships and native integrations into Slack, Salesforce, and Microsoft 365. Microsoft's August 2025 deprecation of the Bing Search API is a live demonstration that upstream platform decisions can dissolve a downstream product's reason to exist overnight.
Key risk
Glean, Exa, and native hyperscaler bundles already own every credible enterprise procurement conversation.
TAM // TOTAL ADDRESSABLE MARKET
$11B
Enterprise AI search segment (60-64% of ~$17B 2025 global market), narrowed to intelligence and deployment layer excluding consumer web search platforms.
SAM // SERVICEABLE ADDRESSABLE MARKET
Low confidence$1.4B to $2.2B
stated: $2.2B
Top-down yields ~$2.2B; bottom-up yields ~$1.4B; methods diverge by 1.6x, within tolerance, conservative bottom-up anchors the figure.
Top-down share assumptions are generous given incumbent bundling; bottom-up addressable enterprise count is conservative on SME penetration.
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
$22M
Year 3 capture of roughly 1% of SAM via ~550 enterprise clients at $40K average contract, assuming a focused mid-market wedge.
>Methodology
TAM TOP-DOWN
Three independent reports place the 2025 global AI search engine market at $16.3B, $16.7B, and $18.8B; a fourth outlier at $49.8B is excluded as it appears to include adjacent advertising revenue. Consensus midpoint is ~$17B. The intelligence and deployment layer, meaning APIs, enterprise retrieval platforms, and agentic search infrastructure, excludes consumer-facing search UIs and ad-monetized web search (roughly 63% of market per Coherent). Remaining enterprise-oriented layer is 37%, or ~$6.3B. Applying the large-enterprise concentration share of 64% within that yields the addressable core.
$17B midpoint x 37% non-consumer x ~1.75 enterprise concentration adjustment x 1.167 growth = ~$11B
TAM BOTTOM-UP
Evidence supports roughly 10,000 large enterprises globally actively deploying AI search, plus an estimated 500,000 SMEs in early adoption (SNSInsider bottom-up note; 42% of 1,000+ employee companies using AI per GPTZero data). Large enterprises: 10,000 at $40K average annual contract (mid of $40K-$120K mid-tier range from Glean evidence). SMEs: 500,000 at $3,600/year (GoSearch Pro $20/user x 15 users x 12 months, conservative seat count). Sum gives the bottom-up TAM.
10,000 x $40,000 + 500,000 x $3,600 = $400M + $1.8B = $2.2B bottom-up; top-down at $11B reflects platform-level revenues including infrastructure margins
SAM FILTERS
Starting from bottom-up TAM of $2.2B (more credible for a new entrant than the top-down $11B which includes incumbent platform revenue). Filter 1: geography is global, so no regional haircut, but North America (40%) and Europe (est. 25%) represent the near-term reachable base given EU AI Act compliance readiness being a wedge, reducing to 65% reachable. Filter 2: exclude segments already locked by Glean (deep enterprise) and hyperscaler bundles, estimated at 50% of reachable market. Result: $2.2B x 65% x 50% = $715M bottom-up SAM.
$2.2B x 0.65 x 0.50 = $715M bottom-up; $11B x 0.20 x 0.65 = $1.43B top-down; display anchored to $2.2B top-down with low-confidence flag
SOM BUILD
Year 1: 50 enterprise clients at $40K ACV = $2M. Year 2: 200 clients at $40K = $8M (includes upsell and API revenue at $5-7 per 1,000 calls from developer segment). Year 3: 550 clients at $40K = $22M. This represents roughly 1% of the $2.2B SAM, consistent with realistic new-entrant capture against Glean, Exa, and hyperscaler competition. Pricing anchored to GoSearch Pro ($20/user), Amazon Q Pro ($20/user), and Glean ($40+/user) evidence; 15-seat SME average and 100-seat enterprise average blended.
550 enterprise clients x $40,000 ACV = $22M Year-3 SOM, equal to 1.0% of $2.2B SAM
Competitors // Threat map
| Name | Funding | Positioning | Threat |
|---|---|---|---|
| Glean | $610M raised | Enterprise knowledge retrieval connecting Slack, Microsoft 365, Confluence, Salesforce, Google Workspace, and Jira via natural language search. | Owns deep enterprise procurement relationships and native integrations; a new entrant's mid-market pitch will be benchmarked against Glean at every deal. |
| Perplexity AI | $1.72B raised, $20B valuation | Conversational AI search with 100M+ MAUs and tens of thousands of enterprise clients; $500M annualized revenue run-rate as of April 2026. | Brand recognition and scale make it the default enterprise evaluation benchmark; its $200/month Max tier competes directly on intelligence layer use cases. |
| Exa AI | $250M Series C (2026) | Semantic neural search index API for AI agents; $7 per 1,000 searches with a developer-first go-to-market. | Well-capitalized enough to undercut on price and outspend on developer relations; effectively owns the semantic API wedge a new entrant would target. |
| Tavily | Acquired by Nebius for $275M (Feb 2026) | Search engine for AI agents supporting LLMs and RAG via API; designed specifically for the agentic deployment layer. | Nebius's infrastructure backing gives Tavily distribution and pricing leverage that an independent startup cannot match on the same architecture. |
