Pick
Linkup
Pick Linkup if you trust traction signals — they list 8 customers, SparkToro lists 3; and you want the better-funded company ($13.2M); and SOC 2 Type 2 matters for your security review.
Head-to-head review · Updated June 2026
Linkup vs SparkToro: which one wins in 2026?
Linkup and SparkToro 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, SparkToro has raised $1.3M; Linkup is the more-funded incumbent; SparkToro is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
SparkToro
SparkToro is the right pick if your team prefers their approach and pricing fits.
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 SparkToro
SparkToro has raised $1.3M (Angel round June 2018 from 35 individual angels ($10K-$100K each)). Founded by Rand Fishkin, Casey Henry, based in Seattle, WA. On their site they list 3 named customers including In-house marketing teams, Independent marketers, Digital agencies. Pricing starts at $0/mo.

- Identifies podcasts, YouTube channels, subreddits, and websites a given audience visits, unique data unavailable elsewhere.

- Limited traditional demographics (age, gender) compared to dedicated demographic data providers.
- Free tier is restrictive: 5 searches per month with only sample results, not full data.
- Few native integrations with marketing tools, so insights typically have to be manually moved into CRM or ad platforms.

- More named customers. Linkup lists 8 customers vs SparkToro's 3, including McKinsey & Company, Cohere, KPMG.
- SOC 2 Type 2. Linkup carries SOC 2 Type 2; SparkToro does not yet, which can hold up procurement.

- Wider integration ecosystem. Linkup integrates with 7 tools; SparkToro ships 3.

Switching from one to the other
From Linkup to SparkToro
Export your saved queries and prompt panels from Linkup (most tools support CSV export). Most SparkToro setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate SparkToro'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 SparkToro to Linkup
Same flow in reverse. Export from SparkToro, 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 SparkToroare 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 SparkToro?
Honestly: neither one fully solves the problem. Linkup and SparkToro 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 SparkToro cost?
Linkup starts at $0/mo. SparkToro 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.
Do Linkup and SparkToro actually improve your AI visibility, or just measure it?
Both Linkup and SparkToro 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 SparkToro?
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.
