summer. is a London-based influencer marketing agency built to operate on both sides of the creator economy. The company works directly with brands on creator-led campaigns while also representing talent through a dedicated management arm; a structure designed to reflect how influencer marketing has grown from experimental spend into a performance-driven business channel.

Founded during the early “blogger era,” summer. has spent the past decade adapting its services as platforms, audiences, and brand expectations have changed. What began as influencer outreach has become a business focused on campaign outcomes, content ownership, and long-term creator partnerships.

Today, summer.’s brand-facing business spans paid partnerships, organic advocacy, experiential activations, affiliate programs, and creator-generated content (CGC). Rather than treating influencer marketing as a standalone tactic, the agency positions creators as flexible assets across awareness, engagement, and conversion objectives.

“At this point, creators are effectively their own broadcast channels,” says Mischa Joslin, summer.’s Managing Director. “What matters is who they’re actually reaching and what they can deliver, not just who they are on the surface.”

She adds, “Our heartland is paid partnerships, but brands are asking for much more than posts now. They want content, they want performance, and they want flexibility in how those assets are used.”

Who summer. Serves

summer. operates as the dedicated influencer marketing arm within b. the communications agency, a London-based earned communications firm with more than two decades of experience across PR and VIP tastemaker work. While the wider group focuses on traditional communications disciplines, summer. was established to fill a specific market gap: a specialist agency focused exclusively on influencer marketing.

“All we do is influencer,” Mischa says. “It was born out of the need for a dedicated agency within that space.”

summer. works with brands across beauty, fashion, food, family, lifestyle, and consumer goods, spanning high-street to premium and luxury categories. Many of its clients are navigating the same challenge: influencer marketing works, but execution has become harder as platforms fragment and organic reach declines.

“The problem for brands is that influence is no longer just about reach,” Mischa says. “It’s about relevance, distribution, and whether content can actually move someone to act.”

At the same time, creators face growing pressure to demonstrate commercial value rather than just audience size. summer.’s model is designed to address both sides of that imbalance, helping brands deploy creators with precision while coaching creators to operate more like businesses.

“Creators are being scrutinized in the same way media channels are,” Mischa says. “Brands want to see link clicks, sales, conversions – and they should.”

How summer. Builds Campaigns Around Outcomes

summer.’s campaign process starts with objectives, rather than talent. Before any creators are shortlisted, the agency works with brands to define what success looks like, whether that is awareness, engagement, or direct action such as web traffic, app downloads, or sales.

From there, the agency analyzes creator data, audience demographics, and historical performance using a mix of in-house tools and third-party platforms. Only after that does it move into casting and outreach, where creators are further vetted based on platform-specific performance metrics and examples of past results.

“There’s a lot of nuance in getting it right,” Mischa says. “It’s not about visual alignment alone. It’s about who the creator is actually speaking to and how.”

She ties this approach to influencer marketing’s shift away from intuition-led casting toward data-informed decision-making, particularly as budgets increase and brands demand accountability.

The Rise of Nano Creators and Content-First Spend

One of the most notable shifts summer. has leaned into is the growing use of nano-level creators and CGC as paid media assets. Rather than relying on organic distribution, brands increasingly license creator content to run as ads across platforms.

“We’re seeing brands move away from big names and toward smaller creators whose content performs,” Mischa says. “That content can then be scaled in paid environments rather than relying on the algorithm.”

For brands, the appeal is efficiency and control. For creators, it introduces a new dynamic in which value is tied to production and performance rather than solely to follower count.

“That shift changes how creators need to think about their role,” Mischa says. “It’s not just about posting. It’s about proving impact.”

Talent Management Built Around Longevity

On the talent side, summer. represents a roster of creators and supports them beyond traditional brand deals. The agency works with talent to develop long-term strategies that include product launches, subscriptions, podcasts, and other revenue streams designed to reduce reliance on platform volatility.

“The algorithm has a shelf life,” Mischa says. “So the question is always what comes next.”

Creators represented by summer. are treated less as inventory and more as collaborators. The agency is selective about who it takes on, prioritizing creators who view content creation as a profession rather than a short-term monetization play.

“We look for people who genuinely love what they’re doing,” Mischa says. “This isn’t a quick-win industry.”

Operating on both sides of the ecosystem also means managing competing interests. summer. avoids forcing creators into partnerships that conflict with their values and steers brands away from creators who pose reputational risk.

“Longevity matters more than a single deal,” Mischa says. “We don’t want creators or brands dealing with fallout later.”

Where the Market is Heading

Mischa expects influencer marketing budgets to continue growing, but deployment to polarize. Brands are either investing in deeper, longer-term creator relationships or scaling volume through nano creators and paid content distribution.

She is also cautious about the industry’s growing interest in AI-driven influencer tools. While automation can streamline processes, Mischa believes the core value of influencer marketing remains human.

“This industry runs on relationships,” she says. “AI can help with admin, but it can’t replace trust.”

For summer., the next phase includes expanding its creator roster into food and family categories, deepening integration with partner agencies, and continuing to adapt its services as platforms and consumer behavior change.

“You can’t stand still in this industry,” Mischa says. “The agencies that survive are the ones willing to change with it.”
