I drive strategic finance advisory specialized in fintech. I've spent 15 years building and supporting neobanks and the infrastructure behind them, from Sift and Chime to Unit and Block. I bring that operator experience to your hardest calls: unit economics, fundraising and the partnerships that change your trajectory.
The best founders and operators trust Interspace
I build from operator experience after 15 years in fintech so every call is based on practice, not theory.
I research every recommendation deeply so it is grounded, specific and practical.
I only earn when you get value. Pricing is entirely ROI-based, so your wins are my wins.
“Samir helped us sharpen our go-to-market and rethink who we were really selling to, and it changed the trajectory of the business. He's generous with his network and even more generous with the hard truths, which is exactly what you want from an advisor.”

Co-founders, Margin
“Samir pushed us to rethink our pricing and positioning from the ground up, and the result is a story that finally lands with investors. He pairs real fintech operating experience with candid, no-fluff feedback, and he backs it up with introductions to the exact people we needed to reach.”

I build with 100x ROI in mind, meaning you get 100x the value for every dollar in expense. We start with a call to get the initial context, set goals, and figure out the toolkit that makes sense, how often we interact, the deliverables, and pricing. I am open to project-based, outcome-driven, and ongoing engagements depending on what the project needs.
I help build your fundraising narrative and open up capital access, and I recommend the strategic partnerships and customer introductions that level up your business.
I create the assets and stories that make your product tangible, sharpen your positioning, and extend your reach across the fintech ecosystem.
I draw on operating experience to help you build strategic finance teams, develop sustainable financial products, and build out unit economics and profitability metrics.
