German B2B influencer advertising platform Passionfroot raised $15 million in Series A funding led by Insight Partners. The marketplace connecting brands with creators in the corporate niche increased revenue 13-fold over the year and is opening offices in the USA and Brazil to expand beyond the European market.
B2B influencer marketing: why brands are turning to bloggers
Passionfroot founder and CEO Jen Fang attributed the platform's growth to shifting strategies among corporate brands. AI tools have simplified product development but intensified competition in every software category. Marketing executives are seeking new channels for brand awareness, and collaborations with LinkedIn bloggers, Substack authors, and YouTube podcast creators have become a priority for B2B companies.
Platform clients include ElevenLabs, Figma, Replit, Framer, and Gamma. Rebecca Liu-Doyle, Managing Director at Insight Partners, noted that demand for influencer marketing in the corporate segment is growing due to the need to explain artificial intelligence technologies: brands require experts who deeply understand the market and create quality content for professional audiences.
AI agent for blogger discovery and performance forecasting
Following a financing round in 2024, Passionfroot launched the AI agent Zest. The tool helps brands find suitable creators inside and outside the platform, create campaigns, and track metrics. The system uses its own creator graph built on reach data and results from thousands of integrations.
Every marketing executive says the same thing: AI turns software into a commodity and floods categories with new products. B2B buyers go to creator channels to find tools in the noise.
The platform offers a wallet for paying bloggers worldwide and controlling media buying expenses. Over 18 months, Passionfroot has paid creators at least $10 million. The company is working on a feature to measure campaign impact on brand citations in AI system responses — a metric becoming critical for assessing brand awareness in the age of generative search.
Expansion into the US market and new tools for creators
Passionfroot co-founder Jen Fang is relocating to New York, where the platform is opening an office to work with the American market. In parallel, an office is launching in São Paulo. The Berlin team of 15 employees will expand.
The startup plans to add features for creators: monetization tips and AI-powered content ideas. This follows the trend of platforms like Substack and Beehiiv, which embed earning tools — Beehiiv launched an advertising marketplace and community last week, Substack introduced exclusive bonuses for newsletter subscribers.
The round also included existing investors Creandum, Supernode Global, and s16vc. In total, the company has raised over $21 million.
Insights for the Russian market: expert selection and media planning
Passionfroot's growth demonstrates corporate brands' demand for expert content and long-term blogger integrations rather than one-off posts. For Russian B2B companies, this means building media plans focused on niche authors in Telegram, VC.ru, and YouTube who explain products to professional audiences. An influencer agency helps select creators by reach and niche relevance, forecast campaign KPIs, and organize media buying — payment and reporting for integrations. If a brand needs a system to manage projects with multiple bloggers simultaneously, the ETC team handles coordination from brief to results analytics.
