The Fintech 5 is a series of blog posts consisting of questions and answers designed to help you get to know the people in the Fintech Sandbox community.
Kristen Castell is the Managing Director of Delaware-based CAFE, a non-profit org with a flagship fintech accelerator program dedicated to improving financial outcomes for low- to moderate-income individuals. In this role, she has built an ecosystem of fintech founders, banks, investors, academia, industry leaders and a program to support the growth of extraordinary fintech companies.
CAFE is one of our Accelerator Partners and several Data Access Residents have participated in this accelerator program.
Kristen has a background as an executive at large financial services firms like JPMorgan and BlackRock, and also as a fintech entrepreneur. She is also a board member and advisor for many non-profit organizations and for-profit fintech companies, including the MicroDreams Foundation (microfinance) and Blended (co-parenting expenses fintech).

#1. Kristen, tell us about your mission at CAFE.
We launched CAFE two years ago with a big vision and mission to be the “center for excellence” for the US in helping to grow mission-driven technologies that improve LMI (low-to-moderate income) people’s lives. Financial wellness is declining across the country for so many people – and by supporting even one company with new innovations in this area we can have a multiplier effect to help thousands and millions of people’s lives. I’m passionate about social impact and how we can bring all the players in the financial industry together, which is good for business, and also has a positive impact to make the system work better for all. CAFE was launched out of the Fintech Innovation Hub in Delaware and works across the US through offering our programs and working with the large community of partners we are building.
#2. What does the CAFE accelerator program offer and who is it designed for?
When CAFE launched, we created a unique accelerator program to help mission-driven fintech companies that have a product in market, some early financial institution customers, and are ready to scale. Our two month program is held twice a year for two months to support six companies at a time. This is an equity-free program that introduces the founders to relationships with investors, financial institution customers, academia, regulators and other industry leaders which is invaluable to their growth. Our next program has opened applications now (until Aug 15th) at www.ftcafe.org/apply and we also plan to launch additional programs and partnerships this Fall 2025.
#3. You moderated a panel for us at Boston Fintech Week in 2024 called “Why I’m Optimistic: What is on the horizon for technology & innovation in financial services.” How would you answer that question today?
This was one of my favorite panel discussions that I’ve led at any conference because of the spirit of the question being “optimistic” and focused on some of the exciting new innovations in the industry and things going right instead of all our concerns (also valid). In my role at CAFE, I get to work with so many people across the financial services industry in a variety of roles that care about our mission of technology + humanity and how we can build innovations that help people’s lives. I see how the fintech founders I work with are collaborative and support each other rather than competitive. It makes me optimistic that there are so many people that “care” and now using technology to create real solutions to problems and building a future that works better for people.
#4. If you could change one thing about the fintech ecosystem, what would it be?
The belief that making money and being focused on helping people is mutually exclusive. In fact, I believe the best way for a fintech or financial services organization to be successful is to focus on the long-term value for their people (employees, customers, suppliers, etc.) and then how that is financial material to long-term profitability. While CAFE is a nonprofit org, we are not a “charity” – when we work with large banks and other organizations we speak to the business contacts that are interested in the technology companies we work with because they could be additive to their business is servicing customers in new ways or obtaining new customers. We also work with the foundations and impact-focused groups that want a scalable way to have a positive impact on LMI people’s lives.
#5. What is the best career or life advice you have received?
“Ask for it.” When I worked at BlackRock, I volunteered as a leader of the Women’s Network and we created a program for employees (especially just starting their careers) on how important it is to ask for opportunities and how to do it. In corporate (and really in every aspect of life), it is important to share about what you are interested in and ask for what you want – so that way the other party has better clarity and can help you get there. It’s these little bold moves and asks that make a difference.
