Full-Service B2B Lead Generation Agency

Peakflow is a Full-Funnel Lead Generation agency that builds custom pipeline engines for B2B companies by integrating sales and marketing into one cohesive strategy.

Most lead gen agencies offer cold outreach. Most marketing agencies offer content and ads. We do both—together.

Our Buyer-Led Approach recognizes that modern B2B buyers don't respond to cold emails alone. They research companies, consume content, check LinkedIn profiles, and build trust before booking a meeting. That's why we combine targeted advertising, strategic content, intent signal tracking, and personalized outreach into custom funnels tailored to your offer, target market, and sales cycle.

What makes us different:

  • We don't run one-size-fits-all campaigns—we build custom lead generation engines
  • Sales and marketing work together, not in silos
  • We warm prospects before asking for meetings (30-120 days depending on your sales cycle)
  • Full-service execution: ads, content, outreach, deliverability, SDR activation, and intent tracking
  • One agency replaces 7+ specialists (ads, design, content, outreach, deliverability)

We work with: B2B SaaS, tech companies, professional services, and agencies with €10K+ ACV products who need predictable pipeline but don't have full sales/marketing teams in-house.

Our clients have booked meetings with: National Geographic, UNICEF, Erste Bank, Roche, and UniCredit.

Based in Croatia, serving clients across US, Canada, Europe, Australia, and New Zealand.
