At J4Change, we speak fluently the language of startups, fund managers, LP investors and Development Finance Institutions (“DFI”).

Testimonials

  • Juanita helped me focus on some of the business fundamentals and think about next steps to build and grow my business. One of the biggest insights was to think about the value proposition for one of our key stakeholders (small businesses) and how to make sure that Green Gooding had a competitive edge.

    François Servranckx

    Founder and CEO of Green Gooding

  • "Juanita is a master of clarity in the chaos. As a mentor at the Stanford GSB LISA Accelerator, she coached us through one of the most challenging (and critical) aspects of our startup journey: simplifying our messaging and sharpening our strategy. What made her stand out wasn’t just her insight—it was her ability to challenge us just right. She pushed us to break from our assumptions about our product and service, helped us prioritize and sequence our business logic, and made sure we could articulate it all in a way that resonated with investors, partners, and customers. Her impact has lasted far beyond our time in the Accelerator. I still hear her voice (smiling, but firm) asking: “Where’s the evidence the investor gets their ROI at that stage?” If you’re lucky enough to work with Juanita, take notes. She’ll make your thinking sharper, your strategy tighter, and your story land exactly where it needs to go."

  • “I have participated in several of Juanita's presentations on circularity and find them well thought through and insightful. Besides a solid keynote, Juanita excelled in providing answers to questions from the audience with enriching responses based on her background knowledge. I would recommend Juanita to be a speaker and facilitator for presentations and workshops.”

    Founder of Pago

  • “Juanita led the Operational Excellence program to revamp the supervision processes and implement their digital transformation. Her drive and her ability to collaborate with diverse teams, manage stakeholders and navigate complex challenges were essential to helping us achieve our transformation goals. She was amazing and a great asset.”

    Head of Operational Excellence, IDB Invest

  • “Juanita transformed the way we work with and interpret business data. Her expertise in data management and her proactive approach to identifying and solving business problems has been invaluable. The user friendly solutions she built in record time for the business users was a game changer. I called her our “IT whisperer”.”

  • I have worked with Juanita during the past 3 years on several projects involving digital transformation, innovation, process improvement, and data automation. She has struck me as a visionary leader who has clear goals in mind and drives multi-disciplinary teams to achieve them through drive, motivation and cross-collaboration. She inspires others to work toward a common purpose, building on each individual’s strengths and capitalizing on teams’ dynamics. Juanita starts projects that others think will be impossible to accomplish and she gets them done, adding immense value to organizations and permeating her kindness, intelligence and vision in others.
