Flying Cat is an expert-driven inbound marketing agency that transforms B2B companies’ deep expertise into organic growth engines.
Our agency uniquely combines SEO precision with genuine thought leadership. We’re built differently from traditional inbound agencies – our team includes former academic researchers, B2B strategists, and journalists who know how to extract and communicate complex expertise at scale.
We don’t chase quick traffic wins. Instead, we build comprehensive inbound systems that turn your expertise into a sustainable competitive advantage. Every piece of content we create, from SEO-optimized blog posts to detailed white papers, stems from direct expert interviews and original research.
One thing that makes our approach unique is our “authority multiplier” system. We take core expert insights and strategically repurpose them across formats – turning one expert interview into SEO content, social snippets, lead magnets, and video scripts. This approach has helped clients achieve remarkable results: 900%+ increases in organic traffic, 2.8x growth in marketing qualified leads, and over 4x directly attributed ARR.
We’re particularly excited about how we’re evolving inbound for the AI age. We’ve developed frameworks that help content perform exceptionally well in both traditional search and LLM environments, while our lead magnets consistently convert at 2-3x industry averages by focusing on genuine expert insights rather than generic tips.
If you’re looking for an inbound partner who can turn your team’s expertise into a scalable growth channel through SEO, thought leadership, and strategic content distribution, let’s talk about your goals.

Finding the right inbound marketing agency for you
The inbound marketing landscape isn’t quite the same as it was in 2022. While traditional agencies try to be everything to everyone, these seven specialists have taken a different approach – mastering specific aspects of inbound marketing and building systems to deliver consistent results.
Whether you need to turn complex expertise into revenue (Flying Cat), challenge conventional demand gen wisdom (Refine Labs), or bridge the gap between paid acquisition and conversion (KlientBoost), there’s now a specialist agency that lives and breathes your specific challenges.
The key is matching your inbound marketing needs with an agency that has proven expertise in that exact area, rather than settling for generalists who claim to do it all.
