FounderSpeak played a pivotal role in helping me prepare for a speech I delivered to Governor Phil Murphy during the New Jersey Economic Mission to Mexico 2025. Their guidance sharpened my message, boosted my confidence, and ensured I communicated with clarity in a high-stakes setting alongside global business and government leaders.

President of the American Mexican Regional Chamber of Commerce
English is my second language, and FounderSpeak helped me strengthen my structure, refine my message, and elevate my presence for an important presentation, without making it feel overwhelming. The feedback was practical, clear, and empowering. If you're preparing for a high-stakes presentation and want to show up at your best, I highly recommend working with them.
— Karem Ospino
Founder of Ospino Consulting, CFO
I had the pleasure of working with FounderSpeak while preparing a speech for the Organization of Latin American Students (OLAS) at William Paterson University. I truly appreciate FounderSpeak, for their expertise, attention to detail, and genuine commitment to helping international business leaders communicate at their best. I highly recommend them to anyone looking to elevate their professional communication and presence.

FounderSpeak prepared me to pitch my business in English before a grant committee — and I walked out with the funding. As a Hispanic professional, my biggest challenge was feeling truly confident in English-speaking environments — and FounderSpeak fundamentally transformed the way I communicate. Their coaching didn't just sharpen my message; it gave me the executive presence and confidence to win under pressure.
