Commercial Growth through Influencer Marketing

Our team manages the full influencer marketing lifecycle, from strategy and influencer selection to contracting, amplification and reporting.

Every recommendation starts with your business objectives and is supported by audience insight, influencer data and clear performance measures.

How do we unlock growth?

Commercial objectives

With over a decade of influencer consultation behind every campaign, we build channel, influencer and content strategies across Instagram, TikTok, YouTube, Pinterest, Facebook and Reddit, tailored to each client’s audience and objectives, capitalising on trends without being led by them.

Whether your goal is awareness, market entry, repositioning or sales, we turn it into a focused strategy with clear priorities and measurable KPIs.

Audience intelligence

Strong influencer marketing starts with understanding who you need to influence.

Using proprietary and third-party tools, we analyse audience demographics, interests, behaviours, platform usage and creator affinity before building a campaign plan.

This insight reveals where your audience is active, which voices they trust and what content is most likely to earn their attention.

Influencer strategy

Follower count alone doesn’t determine brand fit. We assess audience demographics, engagement quality, past partnerships, content performance, category credibility and brand alignment before recommending any influencer.

Each is then segmented by campaign role, whether the objective is niche credibility, broad awareness, new customer reach or long-term advocacy. Every recommendation is data-backed and reviewed by our specialist team.

Delivering brand impact

How do we increase returns?

🎯 Paid amplification

High-performing influencer content should not have to live and die in a single organic post.

With attention increasingly fragmented across channels and platform algorithms constantly shifting, even strong content cannot rely on organic reach alone. We use paid social, influencer whitelisting and wider campaign amplification to extend the life and reach of the best-performing creative, putting it in front of more of the right people.

Because our PR, influencer, performance and social capabilities sit under one roof, we can connect creator content to the wider marketing plan and manage amplification in-house, building more reach, consistency and value from every asset.

🚀 Optimise and scale

We define what success looks like before the campaign begins. Rather than relying on engagement rate alone, we select metrics according to your objectives and track performance throughout the campaign, spanning audience growth, product engagement, conversion, revenue contribution and return on influencer investment.

Campaign dashboards combine in-house reporting with relevant third-party platforms, giving your team a clear view of performance while activity is still live.

Our reports explain what happened, why it happened and how the findings should influence the next stage of your influencer strategy.
