What Trefoil Group does
Trefoil Group is a full-service B2B integrated marketing agency headquartered in Milwaukee, Wisconsin, serving private equity-backed and privately held mid-market companies. Founded in 1994 by Mary Scheibel, the agency operates across six core verticals — manufacturing, packaging, plastics, cleantech and sustainability, logistics, and professional services — with deep, multi-decade specialization in plastics marketing (30+ years). Since its 2024 merger with Florida-based BrandStar, Trefoil has operated as a BrandStar Company while retaining its Milwaukee headquarters and brand identity.
The agency's service portfolio spans branding and strategy, public relations and strategic communications, visual storytelling, content marketing, sales acceleration, digital marketing programs (paid search, paid social, SEO), website development on WordPress, and social media management. Trefoil integrates across a marketing technology stack including HubSpot, Salesforce, SharpSpring, Google Ads, Meta, LinkedIn Ads, SEMRUSH, and StackAdapt. In 2025 the agency launched two differentiated offerings: AI Search Optimization (structuring client content for visibility in generative AI search results) and B2B Accelerate (national broadcast and multi-channel programs for PE-backed mid-market companies).
Trefoil generates revenue through professional services engagements on a quote-based pricing model, delivered via a sales-led, direct engagement GTM motion targeting PE firms and their portfolio companies. Mid-market retainers across integrated marketing programs form the revenue base. The agency is privately held following the 2024 BrandStar acquisition and continues to operate under founder-era leadership including President Jill Schroeder and EVP/Founder Mary Scheibel.
