Best influencer marketing platforms compared: the limit that sets every tier, and the vendors that publish no price at all

Every influencer marketing platform sells the same five jobs: find creators, contact them, agree terms, pay them, and report what happened. The feature lists therefore look identical. What actually separates them is the limit that sets each tier, and whether you can read it before you talk to anybody.

So this page ranks them on exactly that, with the date we read each page, and it names the ones that publish nothing.

The criterion, and why a feature grid cannot settle this

A feature grid is written by the vendor and every row says yes. A tier limit is a commitment. It tells you what you can do before the price changes, and it is the number you will argue about in month four. So the ranking here is: does the vendor publish, on its own site, the price and the limit that sets each tier? We applied it to ourselves at the end of the page too.

The platforms that publish a ladder you can read today

GRIN, at grin.co/pricing, read 21 October 2026. The page is titled "Pricing: Plans from $0" and it is the most complete disclosure in the category. The commercial model is a monthly fee plus a management fee on wallet deposits, and the fee percentage falls as the tier rises, which means the platform is paid more when you spend more unless you move up. The tier limits are gifts a month and creator searches a month, the entry tier is free with 2 live campaigns and 10 gifts in total rather than per month, and the page states that limits reset monthly, that reaching a limit prompts an upgrade rather than an overage charge, and that GRIN takes nothing from what creators earn. It claims a creator pool of 700K+.

Modash, at modash.io/pricing, read the same day. Its stated principle is unusual and worth copying into your evaluation: "Every plan comes with the same core capabilities. Price goes up based on usage." The entry plan is described as being for campaigns with up to 100 creators, the limit that moves between tiers is how many creators you can discover a month, and creator payments are included with no fee up to a published annual ceiling. A platform that does not fence features behind tiers is a platform you can start small on without losing the workflow you tested.

Aspire, at aspire.io, read the same day, sits between the two groups. It publishes a clear product shape, four pillars named Discover and Nurture, Manage and Scale, Affiliate and Ad, and Measure and Refine, and campaign types including product seeding, ambassador programmes, customer referrals, UGC for paid ads and affiliate marketing. It publishes no price: aspire.io/pricing returned HTTP 404 on that date and every call to action is a demo request.

The platforms that publish no price

Four enterprise vendors returned a live pricing URL on 21 October 2026 that renders a form instead of a figure. creatoriq.com/pricing rendered 386 characters of text, all of it a request for pricing. traackr.com/pricing rendered "Request pricing. Schedule a call with one of our platform specialist". hypeauditor.com/pricing rendered "Book your free demo" and, separately, a database it describes as "227M+ database with 35+ filters". influencity.com/pricing rendered no dollar figure at all.

Two more could not be read on that date. upfluence.com/pricing and heepsy.com/pricing both returned HTTP 403 to our request. That is a blocked fetch and nothing more, and no claim about either product appears on this page.

None of this makes an unpriced platform a worse product. It makes it a slower purchase, and it means your first three conversations will be about budget discovery rather than about fit. If you are buying for a team of two with a four month pilot budget, start with the vendors above that publish a ladder.

The five questions that actually separate two shortlisted platforms

Once the price is known, these decide it. How are creator profiles refreshed, because an audience quality figure from six months ago is a different product from one taken this week. Can you pay creators inside the platform, in the countries you need, and what does the payout cost. Does it track affiliate style revenue, since a gifting programme and a commission programme need different attribution. What leaves with you if you cancel, meaning the creator contact details and the content licences. And who owns the usage rights by default in the templates it ships.

What we sell, which is the second measurement these platforms do not run

These six platforms measure one thing well: what happened when a person saw a creator post. There is now a second place a recommendation lands, and it is an answer rather than a feed. When somebody asks an assistant who to buy from in your category, the reply names two or three businesses and the reader usually never opens a source.

The influencer category has already productised that question, which is the strongest evidence it is real. Later sells Creator AEO at later.com/creator-aeo, read 21 October 2026, and baselines what it calls Share of Model across ChatGPT, Gemini, Claude and Google AI Overviews. Impact lists "AI Search Visibility" as a paid add on beside its partnership tiers at impact.com/pricing, read the same day.

AI Knows Us is not an influencer marketing platform. We do not hold a creator database and we do not run payouts. We measure whether the five answer engines name your business for real buyer questions, tell you who was named instead, and do the content and placement work that changes it. The buyer question never contains your brand name, because a question with the name in it returns an answer with the name in it. Every rate is published with a 95 percent Wilson interval, so small moves are reported as noise until they beat it.

Applying this page's own criterion to us: our price and every tier limit are published as server rendered plain text at aiknowsus.com/llms.txt and in six currencies on aiknowsus.com/pricing. Read 21 October 2026, SEO Start is $149 a month in the United States and watches 0 buyer questions, holds 0 credits and reads 0 engines, so it is a demand harvest tier and not a measurement one. Growth at $299 is the cheapest plan reading all five engines, with 100 buyer questions and 1,200 scheduled answers a month. Scale at $599 carries 300 questions and 3,500 scheduled answers. A top up of 1,000 credits is $49. On this criterion we rank first among the measurement vendors, and the check is specific rather than a boast.

Where rivals beat us: Later's Creator AEO sits on a creator network it describes as 20M+ profiles, and we have no creator network; Ahrefs Brand Radar tracks seven surfaces to our five and publishes its per check overage at $0.020 on ahrefs.com/brand-radar; Moz sells an AI search and visibility product from "Starts at $45/month" on moz.com/products, below our published floor. All three read 21 October 2026.

If you would rather build the first shortlist by hand before paying for a database, we keep a separate page on the six in app routes for an Instagram influencer search. No other page on this site links to that one, measured on 21 October 2026 across the 2,227 stored bodies that cover our 2,141 live pages, of which 939, or 43.9 percent, carry no inbound link at all. That share is an upper bound, because a link from a page whose body we cannot read is invisible to the count.

What buyers ask about influencer marketing platforms

Do I need a paid database at all? Not for your first ten creators, who are usually already tagging you. You need one when the shortlist has to come from outside your own audience and be checked for fake followers.

Is the cheapest plan a fair test? It is, when the vendor ships the same core workflow on every tier and only moves the usage limit. That is why Modash's published principle matters more than its headline figure.

Should the platform also handle affiliate commissions? If creator revenue is going to be commission based, yes, because running discovery in one system and attribution in another creates a reconciliation job nobody owns.
