Top 10 Influencer Marketing Agencies for TikTok and Instagram in 2025

Intro

TikTok and Instagram have become the growth engines for consumer-facing brands in 2025. These platforms dominate attention, and the speed at which trends scale creates both opportunity and risk.

The reality is that finding the right creators, filtering out fake engagement, and tying spend back to revenue are still major issues for many teams. That’s why more CMOs and brand leaders turn to influencer marketing agencies to handle sourcing, compliance, and performance tracking.

In this article, you’ll compare 10 firms and see how each one helps you drive measurable results. But first, let’s take a look at what these agencies actually do.

What Do Influencer Marketing Agencies Do?

An influencer marketing agency handles the parts of a campaign that usually drain your internal team, like finding the right creators, negotiating contracts, managing deliverables, and reporting on performance.

On platforms like TikTok and Instagram, these agencies help you reach audiences at scale through content that feels native and unforced. Some agencies act as full-service partners with creative, paid media, and analytics teams, while others focus narrowly on micro-influencers or enterprise-scale programs.

According to recent influencer marketing statistics, the size of this market shows why the model matters more than ever. According to Statista, influencer marketing is valued at $32.55 billion in 2025. With that level of spend, you need partners who can turn audience attention into measurable brand growth.

Next, let’s look at why brands rely on them.

Why Brands Partner with Influencer Agencies

Brands turn to influencer marketing agencies because the real costs of doing it all in-house are high. The pain points usually fall into three areas:

• Limited in-house expertise on influencer vetting and contracts
• Resource-heavy execution across multiple campaigns
• Difficulty tying spend to ROI with reliable tracking

The truth is that an agency acts more like an extension of your team than a vendor. With budgets that typically range from $5K to $100K+ per campaign, you need proof that spend drives results. On average, companies see $6.50 back for every $1 invested in influencer marketing, which is why financial accountability matters.

Objectives also differ. Statusphere found that micro-influencer campaigns focus on brand awareness (65%), content for paid ads (22%), and in-store sales (13%). Agencies can help you connect those goals to measurable outcomes.
