🎧The Fintech OG Series: Charles Birnbaum and Cynthia Loh

Welcome back to this week in FinTech and another episode of the FinTech OGs. This week I'm joined by two guests whose careers have helped shape. The evolution of modern wealth management. We have Charles Birnbaum partner at Bessemer Venture Partners, and Cynthia Loh, who is a senior vice president at Capital One.

Charles and Cynthia first crossed paths in the early days of Betterment. This is back when robo-advisors were just starting to redefine how everyday consumers invest and have spent, over a decade building in, investing in and advising some of the most influential FinTech companies out there. It's a great conversation and I'm excited for you to dive in!

I also want to take a moment to send out a special thanks to our sponsors this week. 100% of what we got in ads for this episode is going towards Texas Flood Relief. Those of you that know me know that I am based in Austin, Texas, and while thankfully my daughter is too young to go to a sleep away camp, it hits close to home with friends having kids that go to camps that were hit along the river.

The two guests this week, Charles and Cynthia, also both have kids, and it's just unimaginable what these parents are going through. I ask all of you to keep these families in your prayers.

With that, I'll also tell you a little bit more about our sponsors. I have a feeling you guys are very familiar with all of them but just in case you're not.

First up is Lithic, who is a modern payments infrastructure provider that enables technically ambitious teams to build better payments products. Lithic's cutting edge technologies cover issuing and processing, end-to-end fraud prevention, dispute management, and cardholder support implemented as either fully managed offerings or self-service tools.

Next up we have Rho, which is the all-in-one banking platform for startups and the accountants who support them. Thousands of startups switching to Rho because they don't have time to wait days to open an account or the patience for email support queues when they just need real help.

Rho is building a new standard for business banking. With Rho, you get fast banking setup, up to 2% cash back on cards and yield on idle cash. Everything you need all in one platform from day one. Every client gets real dedicated support from a team that goes to the end of the earth to help you win.

Head to rho.co/startups to learn more. That's rho.co/startups. Rho is a FinTech company, not a bank or an FDIC. Insured depository institution checking account and card services are provided by Webster Bank NA member FDIC. See rewards terms for complete cash back details.

Last but not least, we have Spade. It’s 2025 and fintechs can spin up cards in minutes and move money in real time. But we still can’t decipher the transactions on a bank statement. Most still show up as a jumble of letters and numbers — no clear name, no location. Just noise and guesswork. 

That’s why so many fintechs and banks are turning to Spade. Spade’s API maps messy transaction strings to verified businesses — returning real merchant names, categories, and store locations in real time. So if you want reliable transaction data across cards, ACH, and more, head to spade.com.
