Head-to-head review · Updated June 2026

Gauge vs Linkup: which one wins in 2026?

Gauge and Linkup both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Gauge has raised $500K (pre-seed), Linkup has raised $13.2M; Linkup is the more-funded incumbent; Gauge is the leaner challenger.

Linkup is cheaper out the gate, but Gauge tracks more AI platforms. The right pick depends on which dimension matters most for you.

The verdict
Pick

Gauge

Pick Gauge if you want the cheaper option ($100/mo vs $0/mo); and you need broader AI platform coverage (4 platforms vs 0).

Pick

Linkup

Pick Linkup if you want the cheaper option ($0/mo vs $100/mo); and you want the better-funded company ($13.2M); and SOC 2 Type 2 matters for your security review.

If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.

The case for Gauge

Gauge has raised $500K (pre-seed) (Y Combinator S24). Founded by Evan Doyle, Caelean Barnes. On their site they list 10 named customers including PostHog, Supabase, MotherDuck, Sourcegraph. They cover 4 AI platforms. Pricing starts at $100/mo.

AI visibility analytics platform for GEO optimization that tracks citation rate, mention rate, and share of voice across ChatGPT, Gemini, Perplexity, and Google AI Overviews.

What people praise

  • Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
  • Tracks every major AI surface, ChatGPT, Claude, Gemini, Perplexity, Copilot, AI Mode, and AI Overviews
  • Documented customer outcomes: Standard Metrics doubled AI visibility in two weeks, Eco saw a 5x improvement in 30 days
  • Reasonable entry price at $100/month and Y Combinator-backed agility on new feature releases

Where it falls short

  • Only a handful of public G2 reviews, less independent sentiment data than incumbents
  • Two-person founding team means roadmap velocity depends on a very small org
  • Claude tracking only included on the Enterprise tier, not on Starter or Growth
  • Article generation volume capped (3 on Starter, 18 on Growth) limits content-heavy use cases

The case for Linkup

Linkup has raised $13.2M ($10M Seed (Feb 2026, led by Gradient)). Founded by Philippe Mizrahi, Denis Charrier, Boris Toledano, based in Paris, France. On their site they list 8 named customers including McKinsey & Company, Cohere, KPMG, EY. Pricing starts at $0/mo.

Search API used by AI agents — the data layer for retrieval-augmented LLM apps.

What people praise

  • Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product
  • Licenses content from publishers and pays them on usage, so results are legal and citation-safe
  • Sub-second search latency is fast enough for real-time agent tool calls
  • Free tier ships 4,000 queries and startups can apply for $5,000 in credits

Where it falls short

  • Per-request pricing makes monthly cost hard to forecast for high-volume agents
  • Deep Research mode can cost up to $2.50 per call, expensive at scale
  • Not a visibility, SEO or content product, it is a raw search API and you build the workflow yourself
  • No G2 or Capterra reviews yet, the company only launched its API in late 2024

Feature parity

What each one ships that the other doesn't. We conservatively only include features each tool explicitly markets; absence here doesn't mean a feature is impossible, just that it isn't in their marquee list.

When each one wins

When Gauge wins
  • Platform coverage matters. Gauge monitors 4 AI platforms; Linkup covers 0.
  • Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
When Linkup wins
  • Budget is the constraint. Linkup starts at $0/mo vs Gauge's $100/mo, so on a per-seat basis it's the cheaper way in.
  • You want the better-funded incumbent. Linkup has raised $13.2M, giving it more runway and shipping velocity.
  • Procurement requires SOC 2 Type 2. Linkup has it; Gauge doesn't yet.
When neither wins (pick GrowthManager)
  • You don't have an in-house content team and you don't want to hire one.
  • You want one $999/mo invoice instead of stacking Gauge plus an agency.
  • You need the team that measures to also act on the data, in the same week.
  • You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.

Reasons to pick one over the other

Reasons to pick Gauge over Linkup

  1. Broader AI platform coverage. Gauge tracks visibility across 4 AI engines vs Linkup's 0.
  2. Wider integration ecosystem. Gauge integrates with 11 tools; Linkup ships 7.
  3. What users praise most. Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around

Reasons to pick Linkup over Gauge

  1. Lower entry price. Linkup starts at $0/mo vs Gauge's $100/mo.
  2. More plan flexibility. Linkup offers 4 pricing tiers vs Gauge's 3, so there's a better chance one fits your team size.
  3. Better-funded incumbent. Linkup has raised $13.2M, giving it more runway and shipping velocity than Gauge ($500K (pre-seed)).
  4. SOC 2 Type 2. Linkup carries SOC 2 Type 2; Gauge does not yet, which can hold up procurement.
  5. What users praise most. Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product

Switching from one to the other

From Gauge to Linkup

Export your saved queries and prompt panels from Gauge (most tools support CSV export). Most Linkup setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Linkup's data againstGauge's; one to two weeks of full reconciliation before you cancel Gauge. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.

From Linkup to Gauge

Same flow in reverse. Export from Linkup, import to Gauge. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.

From either to GrowthManager.ai

We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option

Both Gauge and Linkupare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions

Which is better, Gauge or Linkup?

Honestly: neither one fully solves the problem. Gauge and Linkup are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick Linkup for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.

How much do Gauge and Linkup cost?

Gauge starts at $100/mo. Linkup starts at $0/mo. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.

Which AI platforms do Gauge and Linkup cover?

Gauge covers 4 AI platforms. Linkup covers an undisclosed number of. Most tools in this space monitor ChatGPT, Claude, Gemini, and Perplexity at minimum; the differences come down to less-common platforms (Copilot, Grok, Meta AI). GrowthManager.ai monitors the same four primary platforms and acts on the data.

Do Gauge and Linkup actually improve your AI visibility, or just measure it?

Both Gauge and Linkup are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.

What's the GrowthManager.ai alternative to Gauge and Linkup?

GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
