Operator-built strategic finance advisory, specialized in fintech. I've spent a decade in the space at every stage, from pre-seed to scale, and I bring that rare 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 more than a decade in fintech so every call is based on practice, not theory.
I over-engineer and deeply research everything I do, so every recommendation is one you can actually trust.
I only earn when you get value. Pricing is entirely ROI-based, so your wins are my wins.

I've spent more than a decade building finance functions and partnerships across fintech—from J.P. Morgan and Sift to Chime, Unit, Hudson River Trading and Block. Today I build Interspace Ventures.

“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.”

Co-founder & CEO, InstaSwitch

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 create your design assets from scratch to acquire users, and I expand your reach with hand-built content to a highly leverageable network.
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 draw on operating experience to help you build strategic finance teams, develop sustainable financial products, and build out unit economics and profitability metrics.
