DRDana ReyesHost
Welcome back to The Moneyline Podcast. I'm Dana Reyes, and today I'm sitting down with Sarah Chen from Greenline Capital. Sarah, thanks for making the time.
SCSarah Chen
Thanks for having me, Dana. Long-time listener, and honestly half my team gets their Monday reading from the Daily Line.
DRDana ReyesHost
Let's start at the beginning. How did you end up in alternative finance? Nobody grows up wanting to do this.
SCSarah Chen
No, definitely not. I came in sideways — I was on the operating side of a small business that needed capital fast, and I saw how opaque the whole process was. That stuck with me.
DRDana ReyesHost
And the market you walked into then looks nothing like today's. What's the biggest structural change you've seen?
SCSarah Chen
Data. Ten years ago an underwriter had a stack of PDFs and a gut feeling. Today we see deposit behavior in near real time, and the shops that use it well are just pulling away.
DRDana ReyesHost
Which brings us to underwriting. Everyone's talking about it — separate the signal from the noise for us.
SCSarah Chen
The signal is that it rewards discipline. The noise is the idea that it's a shortcut. If your process is sloppy, better tools just help you make bad decisions faster.
DRDana ReyesHost
Give me a concrete example. Something that happened on a real file.
SCSarah Chen
Sure. Last quarter we had a restaurant group — three locations, great revenue on paper. The pattern in the transfers between locations told a different story. We caught it because we were looking at the right thing, not because we had more data.
DRDana ReyesHost
That's the part I think a lot of brokers underestimate. What should a broker listening right now actually change this week?
SCSarah Chen
Two things. Pre-qualify harder — read the statements before you submit, don't outsource that to the funder. And shorten your funder list. Depth of relationship beats breadth every time.
DRDana ReyesHost
Let's talk regulation for a minute, because it's coming whether we like it or not.
SCSarah Chen
It is, and I think that's fine. Clear disclosure is good for the honest operators. The pain is the patchwork — nine states, nine forms. A single standard would actually lower costs.
DRDana ReyesHost
Where does this go in the next two or three years? Make a prediction you'll regret.
SCSarah Chen
Consolidation. Fewer, bigger funders with real data advantages, and ISOs either specializing or getting acquired. The middle gets squeezed.
DRDana ReyesHost
Lightning round. Best book you've read this year?
SCSarah Chen
Probably something on credit cycles — which tells you exactly how fun I am at dinner parties.
DRDana ReyesHost
Sarah, this was great. Where can people find you?
SCSarah Chen
I'm in the Moneyline community most days — find me in #mca or the funder council. Always happy to talk shop.
