I find my Ikigai when helping the top founders from Latin America.
I've invested in and supported 80 seed-stage companies through my role at Latitud Ventures.
Previously, I co-founded a startup where I held the role of COO and saw, from within, some of the obstacles that founders need to overcome.
Before entrepreneurship, I held an intrepreneurial role at Mercado Libre, where I was part of the team that built Mercado Crédito, now with $4bn in portfolio size.

Testimonials
Matías Gath
Co-founder & CEO - Pulppo
"Marcial has been a sparring partner for Pulppo ever since the seed round. He brings a fresh perspective and deep understanding of how VCs think. Sharpening the axe is critical for every founder that expects to raise a round in this environment, and I can’t think of anyone better than Marcial for the job.”
Matthew Meehan
Co-founder & CEO - Kontempo
“Marcial has been a hands-on partner for Kontempo since day 1. Both Antonia and I value his unwavering support, but more than that we value his honest and original thinking. We rely on Marcial for growth, product and capital markets support. His vision on how to think about fundraising rounds is a key input for Kontempo’s strategy.”
Santiago Rosenblatt
Co-founder & CEO - Strike
“When we went out to raise our $5M Seed Round, it was our first time dealing with VCs. Marcial stepped in, put in the hours to understand our business inside-out, and in only a 60 minutes meeting helped us to reverse engineer the pitch to match what VCs were looking for. Raising with Marcial by our side was critical to the success of Strike.”
Marcela Teixeira
Co-founder & CEO - Apprenty
"The work Marcial did with us can be distilled to one word. Honesty. He did not hesitate to call us out on what we were doing wrong on our pitch deck, and in a very direct, yet kind way, he was able to articulate a narrative to pitch potential clients and investors."
Lautaro Schiaffino
Founder & CEO - Darwin AI
"We met with Marcial in real life to craft the narrative with which we were going to raise our Seed Round. We were impressed at how he was able to craft a narrative that succinctly explained what we were doing in a way that had a perfect fit with what the investors were looking for. We ended up oversubscribing our seed round within the next 60 days."
Luisa Dalla Costa
Senior Associate - Latitud Ventures
"Beyond being an incredible person, from the moment I met him, I recognized his talent and his natural ability to truly add value to founders. We all have a spike where we excel, and Marcial's is evident when you see him interacting with founders. No one crafts better fundraising narratives than he does."
Ignacio Arambarri
Co-founder & CEO - Finanex
"Marcial was the first investor to believe in us. His endorsement, and subsequent value add proved critical for us to raise our Pre-seed and Seed round 12 months later. I’d summarize Marcial as a founder centric individual. I endorse Oss for any founder that is looking to build a tech business in Latin America.”
Paulo David
Founder & CEO - AmFi
"Working with Marcial as part of the support from Latitud's portfolio was crucial for our successful fundraise. The passion and vision with which he addresses every interaction is contagious. This is what we, founders, need. If you are stuck with how you are introducing your company, I fully endorse Marcial's support and guidance."

Matthew Meehan
Co-founder & CEO - Kontempo
“Marcial has been a hands-on partner for Kontempo since day 1. Both Antonia and I value his unwavering support, but more than that we value his honest and original thinking. We rely on Marcial for growth, product and capital markets support. His vision on how to think about fundraising rounds is a key input for Kontempo’s strategy.”
Santiago Rosenblatt
Co-founder & CEO - Strike
“When we went out to raise our $5M Seed Round, it was our first time dealing with VCs. Marcial stepped in, put in the hours to understand our business inside-out, and in only a 60 minutes meeting helped us to reverse engineer the pitch to match what VCs were looking for. Raising with Marcial by our side was critical to the success of Strike.”
Marcela Teixeira
Co-founder & CEO - Apprenty
"The work Marcial did with us can be distilled to one word. Honesty. He did not hesitate to call us out on what we were doing wrong on our pitch deck, and in a very direct, yet kind way, he was able to articulate a narrative to pitch potential clients and investors."
Lautaro Schiaffino
Founder & CEO - Darwin AI
"We met with Marcial in real life to craft the narrative with which we were going to raise our Seed Round. We were impressed at how he was able to craft a narrative that succinctly explained what we were doing in a way that had a perfect fit with what the investors were looking for. We ended up oversubscribing our seed round within the next 60 days."
Luisa Dalla Costa
Senior Associate - Latitud Ventures
"Beyond being an incredible person, from the moment I met him, I recognized his talent and his natural ability to truly add value to founders. We all have a spike where we excel, and Marcial's is evident when you see him interacting with founders. No one crafts better fundraising narratives than he does."
Ignacio Arambarri
Co-founder & CEO - Finanex
"Marcial was the first investor to believe in us. His endorsement, and subsequent value add proved critical for us to raise our Pre-seed and Seed round 12 months later. I’d summarize Marcial as a founder centric individual. I endorse Oss for any founder that is looking to build a tech business in Latin America.”
Paulo David
Founder & CEO - AmFi
"Working with Marcial as part of the support from Latitud's portfolio was crucial for our successful fundraise. The passion and vision with which he addresses every interaction is contagious. This is what we, founders, need. If you are stuck with how you are introducing your company, I fully endorse Marcial's support and guidance."
Matías Gath
Co-founder & CEO - Pulppo
"Marcial has been a sparring partner for Pulppo ever since the seed round. He brings a fresh perspective and deep understanding of how VCs think. Sharpening the axe is critical for every founder that expects to raise a round in this environment, and I can’t think of anyone better than Marcial for the job.”
