Head-to-head review · Updated June 2026

Linkup vs SpyFu: which one wins in 2026?

Linkup and SpyFu 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. Linkup has raised $13.2M, SpyFu has raised Bootstrapped; Linkup is the more-funded incumbent; SpyFu is the leaner challenger.

Linkup is cheaper out the gate, but that's not the only thing that matters. The right pick depends on which dimension matters most for you.

The verdict
★ Our pick
Pick

Linkup

Pick Linkup if you want the cheaper option ($0/mo vs $39/mo); and you trust traction signals — they list 8 customers, SpyFu lists 3; and you want the better-funded company ($13.2M); and SOC 2 Type 2 matters for your security review.

Pick

SpyFu

Pick SpyFu if you want the cheaper option ($39/mo vs $0/mo).

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 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

The case for SpyFu

SpyFu has raised Bootstrapped. Founded by Mike Roberts, based in Scottsdale, AZ. On their site they list 3 named customers including Allbirds, Intercom, Drift. Pricing starts at $39/mo.

Competitor SEO and PPC research tool.

What people praise

  • Years of competitor AdWords data, including ad copy and budget estimates, is the deepest historical PPC archive of any tool in this price range.
  • Reviewers consistently call out affordability versus Semrush and Ahrefs, with the Basic plan starting at $39/mo.
  • Unlimited domain overviews and data exports across all plans, which is unusual versus competitors who throttle exports.
  • Kombat feature visualizes the keyword overlap between three competitors in a single venn-style chart that reviewers find useful for client decks.

Where it falls short

  • Keyword and ad data is noticeably less complete in niche or non-US markets, with reviewers citing missing ads they know competitors are running.
  • Backlink data is thin compared to Ahrefs or Semrush, so most users still need a second tool for link analysis.
  • No real-time rank tracking; reviewers note the SEO rank data lags days behind actual SERP movements.
  • Multiple Capterra and Trustpilot complaints about unauthorized auto-renewal charges and slow support response on billing issues.

When each one wins

When Linkup wins
  • Budget is the constraint. Linkup starts at $0/mo vs SpyFu's $39/mo, so on a per-seat basis it's the cheaper way in.
  • You're enterprise and need to call a reference. Linkup lists 8 named customers; SpyFu lists 3.
  • 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; SpyFu doesn't yet.
When SpyFu wins
  • Years of competitor AdWords data, including ad copy and budget estimates, is the deepest historical PPC archive of any tool in this price range.
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 Linkup 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.

  7. What users praise most. Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product

  2. Faster product velocity. SpyFu has shipped 6 public launches in the last year vs Linkup's 0.

Switching from one to the other

From Linkup to SpyFu

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

From SpyFu to Linkup

Same flow in reverse. Export from SpyFu, import to Linkup. 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 Linkup and SpyFuare 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, Linkup or SpyFu?

Honestly: neither one fully solves the problem. Linkup and SpyFu 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 Linkup and SpyFu cost?

Linkup starts at $0/mo. SpyFu starts at $39/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.

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

Both Linkup and SpyFu 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 Linkup and SpyFu?

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.
