Affirm founder and CEO Max Levchin has a few things flowing in his veins.

One, an admirable work ethic that sees him pushing his own physical boundaries each day. Think working to near exhaustion (yes, for real, as the stories on Levchin are told).

And two, financial services — which perhaps harkens back to Levchin arriving to the United States in 1991 from Ukraine as a teenager in search of the American Dream, with little money at first.

"I came to the U.S. as a teenager, I had no credit history, my parents had an immigrant history, we had no ownership of anything. And so trying to borrow money was completely out of options for us. And so when I got to college, I got a credit card on campus because that's what we did back then, and promptly misunderstood how minimum payments work and got my FICO score trashed. So all the sort of classic immigrant mistakes and like. I understand how the system works, but I needed money. You know, I'm guilty of every one of those things," Levchin told Yahoo Finance Presents.

Fast forward to present day.

Levchin is 46 years old. He is a husband, a father of two young children, the co-founder of PayPal and the founder of Affirm. Despite the impressive resume — which has seen his net worth surge to more than $1.2 billion, according to Forbes — Levchin is back trying to take the buy now, pay later (BNPL) sector to the next level by way of Affirm.

"I did financial services as my first kind of a real project with PayPal. I wandered through the desert for a while and came back to financial services at the urging of my brilliant wife. She said you're good at one thing, go do that thing. I probably am just going to stick to that one thing. Financial services is what I'm good at," Levchin explained.

Affirm is now 10 years old.

The company went public in early January 2021. Shares priced at $49, then skyrocketed to $100 by the close of the first day of trading in part because of the strong rep of Levchin and optimism around the surging BNPL space. By late November, Affirm's stock hit $168 a share intraday. The company landed deals with Amazon, Apple and Shopify.

It even revealed its desire to enter the crypto and debit card space.

Win after win seemingly piled up, overshadowing the fact regulators were starting to eye the industry's business model. And on top of that Affirm still wasn't profitable.

The backdrop has changed a little so far in 2022, however.

As of this article, Affirm's stock is around $42 — well off its record highs north of $160 from 2021. The company's most recent quarter surprised some on the Street as the Amazon deal will be more lucrative over time than immediately upfront. The company also continues to invest aggressively in its business to support future growth, which is still placing pressure on the bottom line.
