ABOUT MICHELLE TENAZAS
I’m a strategic partnerships and portfolio leader in the payments ecosystem, focused on enabling merchants, strengthening partner models, and driving sustainable, enterprise‑level growth. I work at the intersection of merchants, partners, and cross‑functional teams—translating complex payment environments into clear strategies that accelerate activation, adoption, and modernization.My approach blends four core strengths: Partner Enablement — Equipping merchants and partners with the insights, tools, and operating models that unlock growth and improve payment performance. Consultative Leadership — Using data, financial acumen, and active listening to diagnose challenges, align stakeholders, and design solutions that deliver measurable outcomes. Enterprise Thinking — Connecting account‑level needs with broader organizational priorities, from digital enablement to risk, pricing, product, and operational strategy. Innovation — Championing new technologies and emerging payment models, including digital tools, platform-based ecosystems, and GenAI-driven efficiencies.Across American Express, SaaS, and enterprise distribution roles, I’ve led complex portfolios, navigated multi-stakeholder ecosystems, and built scalable partner frameworks that drive long-term value. I’m energized by work that requires cross-functional orchestration, senior-level relationship management, and thoughtful problem solving within evolving payment models.I’m passionate about the future of acquiring, partner-led growth, and ecosystem-based payments—and I love connecting with others building in this space.
