“Long lasting success can only be built when you are able to convince those better than you to join your cause.” I discovered the VC world while studying for my master’s degree in finance in Buenos Aires. Although at that moment the VC industry represented a small space in Latin America, and even less in Argentina, my curiosity about investing in entrepreneurs began to grow every day.

Before joining Wollef, I built my professional career in the financial industry, but the experience that made me get closer to the entrepreneurial ecosystem and understand how hard it is to build a new business was when I worked as a finance manager at an e-commerce startup. During those times I experienced how important it is for entrepreneurs to partner with investors that not only share and support their vision but also aim to build a solid and longlasting relationship with them. That’s why when I had the opportunity to join the Wollef pack I was sure it was the right path to be closer to entrepreneurs and help them from my humble position to undertake their everyday challenges.

I love my job because it is stimulating to have the chance to be a witness to every step our entrepreneurs take to reach their goals and to watch them succeed. I really enjoy talking to these visionary people who have totally disruptive ideas that will probably improve our lives in the future.

Today I think that one of my greatest challenges as a woman investor is spreading the voice among women who want to be part of the VC industry and providing a path to more amazing women entrepreneurs get access to financing.

“Long lasting success can only be built when you are able to convince those better than you to join your cause.” Since I was a little kid, I’ve always had a fascination for innovative solutions and for people that think outside the box. While I was working at EPIC Lab ITAM, the Innovation and Entrepreneurship Center of my university, I discovered the world of Venture Capital and was instantly struck by it. I didn’t hesitate and went “Google: best VC funds in México”. That’s how I found Wollef and the rest is history.

When I was looking for an internship, I had two things in mind: I want to learn, and I want to be part of a team. And those are the reasons why I joined Wollef. Since day one I was sitting in front of entrepreneurs listening to their pitches and involved in the investment process. I believe this says a lot about how Wollef does business, they don’t just write checks, Wollef gets involved with the companies and supports them in every step. And that makes my job as an Analyst much more exciting.

I am passionate about innovation, development, and technology. I am currently studying Business Engineering and Economics in México.

“Long lasting success can only be built when you are able to convince those better than you to join your cause.” I first became interested in the world of startups while pursuing my MBA at The Wharton School. The passion that I saw my classmates bring to the table during this time, through founding their own companies inspired me to work at an early-stage startup. I enjoyed seeing the inner workings of a startup firsthand, however, as a daughter of immigrants to the US from both Argentina and Greece, I knew my calling was to make a bigger impact in the emerging markets my parents came from. I discovered venture capital and knew that a role in this industry would allow me to make the impact I sought not only in Latin America, a region with so much untapped potential, but also across a variety of industries.

My passion for Latin America led me to Wollef where I began my journey as a summer intern and continued my role as an associate since 2021. Prior to starting with the Wollef team, in addition to pursuing my MBA, I spent 5 years working as a mechanical engineer. The bulk this time was in NYC where I worked as an engineer in the real estate industry designing everything from skyscrapers to hospitals. I also had the opportunity to be part of a team building one of the few new recent nuclear power plants in the US. Both roles allowed me to understand how things work, how they’re built, and how important collaboration is. Qualities that I’m proud to bring to the Wollef pack.

I’m excited to see Latin America grow over the coming years and I’m passionate about building a strong and collaborative entrepreneurship community not only across our portfolio companies but also in Mexico and Latin America. On a personal level, I’m excited to see the regions’ engineering and tech talent continue to strengthen.

Outside of the startup world, you can find me watching a soccer game, enjoying an afternoon on the golf course, or playing the guitar with friends.

“Long lasting success can only be built when you are able to convince those better than you to join your cause.” Entrepreneurship has been the constant in my life. Starting with my first venture at the age of 17, I’ve never stopped. I believe entrepreneurs are society’s engine of progress and that one idea partnered with unstoppable grit can change the world.

I’m a contrarian at heart. Taking the road less traveled and hard work can make all the difference. You cannot do what everybody does and expect different results. I studied and practiced law – becoming a partner at a law firm would have been the natural road to success. But it didn’t feel right, and I took a different path. I’m thankful for it every day. I’m a resolute optimist. Things can be better, and we can make them better. Whether we think we can or think we cannot, we’re both right. It is our choice whether to focus on how everything can go wrong or on how we can improve our situation. This is the essential entrepreneur super power.

I love underdogs. It is easy to root for the perennial champion running with the wind at their back. It takes sinew to carry on when you know that victory is not only difficult buy highly improbable. This must explain my love for the Cubs and Cruz Azul ;-)
There is no success without some degree of luck. But it is not the ‘I won the lottery!’ kind of luck. It is the ‘I prepared so hard for this opportunity that when it knocks on my door, I’ll be ready’ kind of luck that matters. The more you put in the effort and put yourself out there, the luckier you’ll be.

Teamwork is the key to great achievements. The myth of the lonesome genius coming up with the breakthrough idea is only a myth. Long lasting success can only be built when you are able to convince those better than you to join your cause. My greatest achievement is the family I’ve built, and it is because I was able to convince a much better person than I to be my wife.
I encourage you to drink deeply from good books for I know no wise people who aren’t readers. If you’d like to know more about me, I sometimes share my thoughts with the world.

“Long lasting success can only be built when you are able to convince those better than you to join your cause.” I’m a fortunate guy

I’m fortunate to be the son of loving parents: an entrepreneur Mother who waked every day at 5 AM & went to bed no earlier than 11 PM; A Mother that woke so early in part to prepare the sandwiches that I would later sell at the school bus, at what was my first of many entrepreneurial experiences. A Father who was a voracious reader & taught me the pleasure of continuously learning from all sorts of disciplines; a Father that also taught me, through helping him decide his weekly soccer bets, the value of making decisions with hard data
I’m fortunate to be the younger brother of my only Brother, to which I once told, being completely wasted: I love you because you’re the best brother I have. A Brother to whom I owe the most valuable advice I have & will ever receive, although not always accurate, because part of it included becoming a life-long suffering fan of the Dallas Cowboys
I’m fortunate to be the parent of three amazing kids, whom I love with all my heart, but whom have had to endure my ineptitude as a father, but that fortunately thru the wisdom of the women in their lives, are finding their pathways to happiness
I´m fortunate to be the husband of the most kind, courageous, intelligent, and beautiful woman on earth, whom has had the courage and kindness to see beyond my many limitations and has focused on the immense love I feel for her. By her hand, until the end of my life, we can, and we will, accomplish everything
I’m fortunate to have partnered with much more intelligent people that I am, starting with my fellow GP, that although has not understood that the best Avenger is Tony Stark, & not the boring Steve Rogers, has helped Wollef make the best possible decisions, avoiding all the idiocy I continuously bring to the table
I’m fortunate to love what I do: getting to know courageous entrepreneurs & be able to partner with them in their exciting journey of creating fantastic companies with meaningful purposes, enlightening cultures & relentless talent
I’m fortunate to have failed many, many, times, & thru those failures, learned & earned a life of happiness; & most important, a life with meaningful relationships.

We believe in building long lasting relationships with the entrepreneurs we partner with.
