A platform is better if you want to run influencer marketing in-house, with your own data and your own creator relationships. An agency is better if you want to hand the whole thing off. That’s the short version. In reality, most brands that treat influencer marketing as a permanent channel end up on a platform, often with an agency plugged in for the creative work. Kolsquare, a global influencer marketing platform with European roots and millions of verified creators across 180 countries, is built for exactly that in-house setup.
An agency sells you time and expertise. Strategy, creator selection, negotiation, execution, all billed per project or on retainer. A platform sells you data and workflows instead: your team still does the work, but faster and with much better information. Kolsquare is in the second camp. Founded by Quentin Bordage and now part of Team.Blue, it’s a certified B Corp, GDPR-compliant and European, which matters more than it sounds once procurement gets involved.
Three budget lines get mixed up in this comparison. The software: Kolsquare plans are tailored to each client’s needs, scoped to users, markets and modules. The service: agencies charge project fees or retainers, often plus a percentage of campaign budget, so costs scale with every campaign you run. And the creators: their fees exist in both models and follow market dynamics, not your vendor choice. Per Kolsquare’s guide Beyond the post: rethinking influencer pricing and payments, creator fees are increasingly performance-based (engagement, reach, conversions rather than follower counts), awareness CPMs have almost halved since their post-Covid peak, and conversion campaigns typically run on hybrid affiliate/fixed-fee deals. The practical difference: with a platform, the recurring cost is fixed and the creator budget is transparent to you; with an agency, service margins sit inside the campaign price.
No in-house team? Running a one-off campaign? Buying creative work such as concepts, content production or a celebrity deal that needs an experienced negotiator? That’s agency territory, and paying a service margin for hands-off execution is a fair trade there.
The math changes once influencer marketing becomes a permanent channel. From a few campaigns a year, software usually pays for itself, because the creator relationships, the data and the learnings stay in the building rather than leaving with the agency contract. Kolsquare’s reporting runs on Earned Media Value (EMV), a transparent formula that estimates what your campaign’s reach and engagement would have cost as paid media. More than 2,000 brands and agencies work this way, Coca-Cola, Netflix, Sony Music, Sephora, Hermès and Lush among them. On G2, the platform is rated 4.4/5 (53 reviews, July 2026).
Plenty of agencies run on Kolsquare themselves; the platform is multi-client, multi-market and white-label ready. That opens a third option for brands: keep the data and creator relationships in your own account, and let the agency execute inside it. You get the service without the black box.
Usually yes, once you run campaigns regularly: Kolsquare plans are tailored to each client’s needs, while agency retainers typically cost more and scale with every campaign. They are different budget lines: software vs services.
No. Kolsquare is demo-led with personal onboarding and Customer Success, so your team is guided from day one.
Yes. A common setup: the brand owns data and creator relationships in the platform, and the agency executes campaigns inside it.
The usual trigger is permanence: once influencer marketing runs continuously rather than as one-off projects, the platform subscription amortizes and the in-house data starts compounding. Many brands keep an agency for creative production and move discovery, management and reporting in-house.
EMV estimates what a campaign’s organic reach and engagement would have cost as paid media, using a transparent formula. Kolsquare uses it as the backbone of campaign reporting, so ROI is comparable across creators, campaigns and markets.
Kolsquare shows a compliance/credibility score per creator profile, aligned with the self-regulatory organizations in the UK, France, Germany, Italy and Spain: ASA (UK), ARPP (France), Werberat (Germany), IAP (Italy) and Autocontrol (Spain). That applies to whoever runs the campaign.

Brands measure influencer marketing ROI by comparing campaign costs with the value generated through engagement, traffic, and sales. Marketers typically track metrics such as earned media value (EMV), engagement rate, conversions, and cost per acquisition (CPA) to evaluate performance.
Yes. In the UK, the ASA and CMA oversee influencer marketing. Ads must be clearly disclosed with #ad, #gifted, Paid Partnership, or a similar label to avoid penalties.
Earned media value (EMV) is an estimate of how much the reach, impressions, and engagements generated by a campaign would have cost to generate through other digital marketing channels.
Instagram is the most popular influencer marketing platform in the UK, chosen by 92% of brands and agencies, according to Kolsquare’s State of Influencer Marketing Report. TikTok, YouTube, and LinkedIn are also popular choices.
Influencer marketing budgets continue to grow in 2026, with brands now allocating between 20% and 30% of their total marketing spend to creator collaborations and up to 50% among digital-first brands. This growth reflects a shift from one-off sponsorships to full-funnel strategies combining awareness, engagement, and conversion.
Average fees vary widely depending on the platform, creator tier, and campaign scope. While Instagram remains a key driver for brand visibility, TikTok dominates short-form engagement and YouTube commands higher investments due to long-form storytelling and production value. However, the era of fixed “price-per-post” grids is over. Pricing now depends on objectives, deliverables, and metrics, whether that’s EMV, affiliate sales, or UGC production.
Pricing models also differ: some creators charge flat fees, others link compensation to performance. Industry and region also influence costs. Beauty, fashion, and luxury often command higher rates than tech or B2B sectors, and fees in France or the UK are generally above Southern European averages.
2026’s influencer marketing is closer to media investment than PR spend. Campaigns that combine organic content, paid amplification, and creative storytelling deliver stronger returns, but also require bigger budgets and greater precision in planning.
As influence becomes more professionalised, costs reflect not only visibility but also the discipline, creativity, and trust that creators bring to sustained brand growth.

Influencer marketing is a type of social media marketing where companies collaborate with people who have significant (typically above 5,000 followers) accounts.
The first step is selecting influencers with audiences that align with your target demographic and campaign goals. Then, you encourage or pay the creator to post content featuring your brand.
Influencers promote products or services in many ways, including:
Put simply, influencer marketing is a form of social media marketing where brands collaborate with popular individuals to promote products or services.
Brands find these influencers appealing because they have established credibility and a loyal following within specific niches, such as fashion, beauty, fitness, or gaming.
Influencer marketing remains highly effective in 2026, but brands can no longer rely on basic campaigns to gain traction. Brands must recognise that targeted and considered influencer marketing campaigns will outperform those that overfocus on superficial metrics like follower counts and reach.
The particular influencers that brands choose matter. Brands need to conduct deep research into the influencer's content, their audiences on different social media platforms, and other relevant data. New tactics like working with influencers in different niches yet similar content styles are also emerging. For example, a beauty brand may work with an Instagram artist to gain visibility with a new audience.
Brands are increasing their investments in content marketing, dedicating significant portions of their budgets to influencer-driven content creation. However, marketers must be vigilant, as influencer fraud remains a challenge, with fake followers and bots undermining the effectiveness of campaigns. Successful influencer campaigns today rely on forming genuine brand-creator partnerships that go beyond one-off collaborations.
Instagram continues to dominate, with Instagram Reels driving engagement and the majority of Instagram users interacting with influencer content. Despite Instagram's domination, YouTube, Facebook, and TikTok remain key players. Many brands hoping to connect with Gen Z through IM still opt for TikTok due to its young demographics. Brands seeking broader reach often adopt multi-platform strategies, incorporating Instagram, Facebook, TikTok, and YouTube into their campaigns simultaneously to maximise engagement.
While IM still influences purchase decisions, the content must be strategic and authentic. Half of marketers now prefer working with smaller creators who foster genuine connections with their followers, rather than relying on traditional celebrity influencers.
The growth in the creator economy means influencers have greater capabilities and tools at their disposal, enabling them to produce more professional content. In 2026, influencer marketing remains an effective way for brands to engage their audience.
Brands can contact agencies to handle their campaigns or use an influencer platform to support in-house strategies.
Agencies offer more support, but they come at a higher cost. Platforms are a more cost-effective alternative that maintains creative control.
In addition, for brands that work successfully with an agency for influencer marketing, investing in the Kolsquare influencer platform offers the flexibility of a two-pronged strategy that could see ongoing campaigns run in-house, while leaving large, one-off campaigns that combine traditional marketing elements to the agency.
