The short version: influencer platforms are searchable databases of creators plus some campaign tools bolted on, and for a small brand they save you time finding people but they don’t do the vetting, the negotiating, or the relationship building for you. Expect to pay anywhere from nothing (marketplace models like Shopify Collabs) to £500 to £5,000 a month for dedicated software, and expect to spend more hours managing the process than the sales pages ever tell you.
What an influencer platform is
Strip away the marketing copy and an influencer platform is three things stitched together: a searchable database of creators with follower counts and engagement stats, a messaging or briefing tool so you can contact them without hunting for email addresses in bios, and some kind of payment or tracking layer so you know who got paid and who delivered a post.
That’s it. It is not a talent agency. It is not a team of people who understand your brand. When you sign up to something like Grin, Upfluence, Modash, Heepsy or the TikTok Creator Marketplace, you are buying access to a filterable list, not a partner who will pick the right ten people for a candle brand in Bristol versus a protein bar brand in Leeds. You still have to know your audience well enough to search for it.
The two models small brands use
Most platforms fall into one of two buckets, and the difference matters more than the brand name on the tin.
- Marketplace models. Shopify Collabs, Creator.co, and Instagram’s own creator tools work like a job board. Creators apply to work with your brand, often for free product plus a small fee, and you approve or reject. Low cost, low commitment, and the quality varies wildly because anyone can apply.
- Managed campaign software. Grin, Upfluence, Aspire (formerly AspireIQ), and Later Influence (built on what used to be Mavrck) give you search filters, outreach templates, and reporting dashboards, but you are still the one doing the searching, the outreach, and the judgement calls. These tend to be priced for brands with a real influencer budget, not a first campaign.
Grin’s pricing isn’t published, which is itself a signal, but sales calls I’ve sat in on for clients have quoted starting points around £2,000 to £4,000 a month, aimed at brands already spending five figures a month on creators. Upfluence has historically started closer to £700 to £900 a month. Modash is the cheapest of the serious tools, with plans from roughly £120 a month for search access alone. Heepsy has a free tier that lets you search a small number of profiles before it locks you into a paid plan starting around £60 a month.
None of that includes what you pay the creators themselves. That’s a separate budget line that platforms rarely make obvious until you’re three screens into checkout.
A real campaign, with real numbers
I ran a micro-influencer campaign for a client I’ll call Wick Lane, a small candle brand doing about £15,000 a month in revenue through Shopify. We used Modash to build a list of 60 UK-based creators with 5,000 to 25,000 followers who posted about home, autumn, or cosy interiors. We filtered out anyone with an engagement rate under 2 percent, which cut the list to 28.
We reached out to all 28 by hand, not through a mass template. Nine replied. Six agreed to a paid post plus a story for £75 to £150 each, plus free product worth about £20 per box. Total spend across the campaign, including the software subscription for that one month, came to just under £900.
The result: 41 story mentions and posts, a bump of about 340 new Instagram followers over three weeks, and 22 tracked sales through unique discount codes, worth roughly £660 in revenue. On paper that’s a loss if you only count direct sales against spend. But the brand’s email list grew by 190 people who’d never heard of them before, and three of those six creators kept posting about the brand unprompted for months afterward because they’d liked the candles. That long tail is where the actual value sat, and no dashboard in Modash or anywhere else measured it for us. We tracked it by hand in a spreadsheet, cross-referencing it against the brand’s own social listening for brand mentions so we could catch the organic reposts the platform never flagged.
What the sales pages don’t tell you before you sign up
Here’s the bit that gets glossed over on nearly every “best influencer platforms” listicle: the follower counts and engagement numbers inside these tools are self-reported or scraped, and a meaningful chunk of them are inflated. Modash and Heepsy both run fraud detection that flags obvious bot farms, but “obvious” is the key word. A creator can sit at 4 percent fake followers and 96 percent real ones and still pass every check, and you’d have no way of knowing without pulling their actual audience insights, which most creators won’t hand over until you’re already in a paid conversation with them.
That means the platform’s job is to shrink your search time, not to guarantee quality. The vetting still has to be a human being reading captions, checking comment sections for real conversation versus emoji spam, and looking at whether the audience looks like your customer. Software will never do that reliably, and any brand that treats the platform’s engagement score as gospel is going to waste a chunk of its budget on creators whose numbers look good and whose actual influence is close to zero.
The second thing nobody says out loud: platforms are built for brands with existing budget and existing team capacity, not for a solo founder trying to squeeze this in between fulfilling orders. If you don’t have four or five hours a week to run outreach, negotiate rates, chase content, and check performance, the platform subscription becomes a cost with no one driving it. That’s exactly the gap a lot of small brands fill by hiring someone through an Indeed virtual assistant to manage creator relationships day to day, because the software was never going to run the campaign for you.
Step by step: running your first platform-based campaign
- Step 1. Pick a platform based on your budget, not its features list. If you have under £2,000 a month total for influencer marketing, start with a marketplace model or a cheap search tool like Heepsy or Modash rather than Grin or Aspire.
- Step 2. Build a filter that matches your actual customer, not a vague category. “Home decor” returns thousands of profiles. “UK, 25 to 40, posts about small flats and budget decorating” returns a usable shortlist.
- Step 3. Cap engagement rate filters at realistic numbers. Anything above 8 percent on an account over 50,000 followers is worth double-checking manually, because organic engagement rarely stays that high at scale.
- Step 4. Message people yourself, or have someone do it who can write like a human. Mass templates get ignored. My reply rate on personalised messages that referenced the creator’s actual last three posts was over three times higher than the templated version we tested against it.
- Step 5. Pay a flat fee plus product, not just product. Unpaid “gifting” campaigns get you posts from people who need the content for their own feed anyway, which tells you nothing about how they’d perform if motivated.
- Step 6. Track results outside the platform too. Use unique discount codes and UTM links, and check which numbers correlate with sales rather than trusting reach and impressions on their own, because most social media metrics don’t predict revenue the way brands assume they will.
When a platform is the wrong tool for you
If you’re a small brand, under £30,000 a month in revenue, doing your first ever influencer push, I’d tell you to skip the software entirely for round one. Spend a weekend on Instagram and TikTok search, follow 40 relevant creators in your niche, comment on their posts for two weeks like a normal human being, then DM the ten who engaged back. It costs nothing but time and it teaches you what a good fit looks like before you’re paying £120 a month for a search tool.
Once you’ve done that manually and know roughly what “good” looks like for your brand, a platform speeds up the second and third campaigns because you already know what to filter for.
If instead you’d rather hand the whole thing to someone else, that’s a fair call too, and it’s worth being honest with yourself about which one you want. A freelancer or a small agency running your creator outreach will usually cost more per month than a software subscription but less than your own time is worth if you’re the founder. It’s the same trade-off covered in what a marketing agency’s social media work looks like when you hand it over rather than trying to run it in-house, and it applies just as much to influencer work as it does to your own posting schedule.
And if budget is the real blocker, not time, you can measure most of what matters without paying for analytics software at all. I’ve written a full walkthrough on how to measure social media success without a paid analytics tool, and the same spreadsheet approach works fine for tracking a handful of influencer posts a month.
Frequently asked questions
Do small brands need an influencer platform to start working with creators?
No. A small brand can find and contact micro-influencers directly through Instagram or TikTok search for free, and many successful first campaigns are run entirely without software, using manual outreach and a spreadsheet to track results.
How much does an influencer platform cost for a small business?
Entry-level tools like Heepsy start around £60 a month and Modash around £120 a month for search access. Fuller campaign platforms like Grin and Upfluence are priced for bigger budgets, often starting at £700 a month and up, before you’ve paid a single creator.
What’s the biggest mistake small brands make with influencer platforms?
Trusting the engagement scores shown on the platform instead of checking the comments and audience quality by hand. Follower counts and engagement rates can be inflated by bots or engagement pods, and no platform catches all of it, so manual checks still matter.
Are influencer platforms worth it for a brand doing under £20,000 a month in revenue?
Usually not as a first move. It’s cheaper and more instructive to run one or two campaigns manually first, learn what a good creator fit looks like for your audience, then use a paid platform once you’re running campaigns often enough that the time saved is worth the monthly fee.
