Not Fintech Investment Advice: Polar,  Multiply Mortgage, OpenTrade, & Spinwheel

Welcome back to Not Fintech Investment Advice, where Simon Taylor and I talk about fintech companies that we're definitely not giving investment advice on. We kick things off with Polar (think Stripe Billing but for LLMs). Polar tracks things like token usage, execution time, and even GitHub access to handle metered billing for AI-native products. It's not even payments; it’s pre-payments, too. Polar helps you charge for the thing before the thing happens. Hey, as AI agents start shopping for themselves, someone has to keep the receipts… Next up is Multiply Mortgage. “Mortgage-as-a-benefit” sounds cursed, but here we are. Multiply partners with employers to offer discounted mortgages (plus human advisors) to employees with zero cost to the company. Their bet is housing is the new healthcare: too broken to fix individually, but too big for employers to ignore. Especially useful in tech, where compensation is equity-heavy and underwriting gets weird. But it’s also a bet on this macro moment in time; if rates drop or unemployment spikes, the model may crack. Then there’s OpenTrade. Yield-as-a-service for stablecoins. Most stablecoins can’t offer interest directly (thanks, regulators), but OpenTrade does the regulatory gymnastics to plug stablecoins into money market funds via tokenized swaps. But I wonder what’s more disruptive: the yield or the regulatory workarounds? You can’t stop yield from sneaking in the side door (and honestly, why try?). Last up is Spinwheel (think Plaid, but for liabilities). While Plaid figured out the asset side of your balance sheet, Spinwheel builds pipes for the other half: credit cards, BNPL, student loans, and more. They started with embedded debt repayment and found their niche by giving lenders the kind of granular, real-time liability data that credit bureaus can’t (or won’t) offer. With Section 1033 on life support, is Spinwheel poised to become the only player with coverage that actually matters? Plus, manifestations: can someone please build a public credit bureau (kind of like a USPS for liabilities)? And while we’re at it, a stablecoin for the unbanked/underbanked that isn’t built on Tron?
