geoSurge
A London seed-stage AI-visibility platform with a free, BYOK ChatGPT/Claude/Gemini tracker and an Enterprise-only "Corpus Engineering" toolkit — $12M raised July 2026.
Our verdict
geoSurge's free BYOK tier is a genuinely generous way to start tracking ChatGPT/Claude/Gemini visibility with full API and MCP access at no software cost — but its real differentiator, Corpus Engineering, is entirely Enterprise-only and demo-gated, and its three-engine coverage is narrower than most rivals in this index.
Added 2026-07-25 after a fresh $12M Seed round (announced 2026-07-03, led by AlbionVC) put geoSurge on the radar — it clears this index's two-independent-source bar comfortably on press coverage (PYMNTS, UKTN and others independently corroborate the round) even though it has no G2/Capterra history yet, being only months removed from a December 2025 stealth launch. Re-verify pricing, engine coverage and Enterprise scope as the product matures.

New tools, fresh verdicts, and who's earning the top spots. One short email.
What's great
- A genuinely free, unlimited-prompt BYOK tier that already includes a full REST API, CSV/JSON export and MCP access — most rivals in this index meter or paywall API/MCP access.
- Backed by a $12M Seed round announced 2026-07-03 — led by AlbionVC, with angel investors from Google DeepMind, Microsoft AI and Signal AI — among the largest reported Seed rounds in the GEO category to date.
- Its Enterprise tier pursues "Corpus Engineering" — logit-level analysis and tooling aimed at actively shaping how models learn to represent a brand, a different angle than pure citation tracking.
Watch-outs
- Tracks only three AI engines — ChatGPT, Claude and Gemini — with no stated coverage of Perplexity, Microsoft Copilot or Google AI Overviews, narrower than most rivals in this index.
- The company's own actual differentiator, Corpus Engineering, is entirely gated behind a custom-quoted, sales-led Enterprise plan — the free tier is pure measurement, not the optimization capability geoSurge markets itself on.
- Only months removed from a December 2025 stealth launch, with no visible track record on G2, Capterra or similar review platforms as of 2026-07 — its own case-study and customer claims can't yet be cross-checked against independent user reviews.
- The free tier's BYOK model means cost scales with the buyer's own API usage rather than a flat fee — high-volume tracking can get expensive on the AI provider's own per-token pricing, unlike rivals that bundle prompt costs into a flat subscription.
Also note: No stated support for Perplexity, Microsoft Copilot or Google AI Overviews on any tier.

What is geoSurge?
geoSurge is a London-based AI-visibility and Generative Engine Optimization (GEO) platform, founded in 2025 by CEO Francisco Vigo and CTO Jons Mostovojs, that tracks how brands are represented inside ChatGPT, Claude and Gemini answers. It emerged from stealth in December 2025 and announced a $12M Seed round in July 2026 (led by AlbionVC, with angel investors from Google DeepMind, Microsoft AI and Signal AI) — among the largest reported Seed rounds in the GEO category to date. Beyond monitoring, its Enterprise tier pursues what it calls "Corpus Engineering": a proprietary approach aimed at shaping how AI models learn and represent a brand over time, not only measuring the result.
What does geoSurge do?
geoSurge's free, BYOK (bring-your-own-API-key) tier runs unlimited tracked prompts across ChatGPT, Claude and Gemini, reporting brand visibility, named competitors, cited sources, and how a brand's representation trends over time; because it is BYOK, ongoing cost is only the buyer's own OpenAI/Anthropic/Google API usage — there is no geoSurge subscription fee at all on this tier. The same free plan ships a full REST API, CSV/JSON export and MCP access, unlimited seats, projects and countries, and a choice of tracking cadence (daily, weekly or bi-weekly) — unusually generous for a $0 tier in this index. The custom-quoted Enterprise plan adds the company's real differentiator, Corpus Engineering: logit-level token-probability analysis, real-time AI-crawler traffic classification, and a "Boost, Crawls and Rephraser" toolkit aimed at actively influencing what AI models learn and cite about a brand, plus a tokenizer tool and a dedicated Slack-based account manager. Enterprise customers the company reports serving span financial services, education and hospitality across four continents, though an exact customer count is not independently disclosed.
How geoSurge works
- On the free BYOK tier, connect your own OpenAI/Anthropic/Google API key and track unlimited prompts across ChatGPT, Claude and Gemini, paying only your own API usage.
- geoSurge reports brand visibility, named competitors, cited sources, and how the brand's representation trends over time, on a daily, weekly or bi-weekly cadence you choose.
- Pull the same data through a full REST API, CSV/JSON export or MCP access, included on the free tier itself.
- On the custom-quoted Enterprise tier, use the Corpus Engineering toolkit — logit-level token-probability analysis and a 'Boost, Crawls and Rephraser' set of tools — aimed at actively shaping how models learn to represent the brand.
Who is geoSurge for?
- Technical teams comfortable bringing their own OpenAI/Anthropic/Google API keys who want a genuinely free, full-featured way to start tracking ChatGPT/Claude/Gemini visibility with API and MCP access from day one.
- Teams that want unlimited seats, projects and countries plus a full REST API on a $0 tier, rather than metered or paywalled programmatic access.
- Enterprises interested in the emerging 'Corpus Engineering' approach — actively shaping how AI models represent a brand — rather than only measuring the result.
Key features
- Free BYOK prompt tracking: Unlimited tracked prompts across ChatGPT, Claude and Gemini on the $0 tier — the buyer only pays their own OpenAI/Anthropic/Google API costs.
- Competitor & source tracking: Reports which competitors AI models name instead of the brand and which sources they cite when answering.
- Corpus Engineering toolkit (Enterprise): A "Boost, Crawls and Rephraser" toolkit plus logit-level probability analysis aimed at actively shaping how models learn and represent a brand, not just measuring it.
- REST API, CSV/JSON export & MCP access: Included on the free tier itself, not gated to a paid plan.
- Real-time AI-crawler traffic classification (Enterprise): Classifies AI-crawler traffic hitting the brand's own site in real time.
What are geoSurge's use cases?
- A budget-free first read on ChatGPT/Claude/Gemini visibility: A team with its own OpenAI/Anthropic/Google API keys tracks unlimited prompts at no software cost, paying only their own API usage.
- Enterprise brand-representation programs: A large brand books an Enterprise plan to run logit-level analysis and the Corpus Engineering toolkit aimed at shaping — not just tracking — how models represent it.
- Agent/automation access to visibility data: A team uses geoSurge's MCP access, included on the free tier, so an AI agent can query visibility data directly.
Why use geoSurge?
- The only visibility tracker in this index with a genuinely free, unlimited-prompt tier (BYOK) that already includes a full REST API and MCP access — most rivals meter or paywall API access.

- Its Enterprise tier targets "Corpus Engineering" — actively shaping what AI models learn and cite about a brand — a different angle than pure citation/visibility measurement.
