Casca

Make Banking Magical

Casca is an AI-native platform transforming small business lending by enabling banks and lenders to originate 10x more loans with 90% less manual effort. Our solutions streamline the entire loan process—from customizable application forms and secure applicant portals to AI-powered assistants, automated document collection, KYB checks, and underwriting. We’ve found product market fit and are scaling our team very quickly. Small businesses are the heart of the American economy. Many banks shy away from providing funding because of the manual effort in pursuing those deals. With us, that changes. We unlock affordable, quick bank funding for the 30M+ small businesses in the US who would otherwise be subject to the high interest rates from predatory online lenders. We are a world-class team of banking & AI experts from Stanford, MIT & Y Combinator. We like to win and we know that the only thing between us and the title is our own ability to improve every day.

Cash Flow Portal logo

Cash Flow Portal

Investment management platform for real estate

Cash Flow Portal is an investment management platform for real estate. We launched 5 months ago, and we have 6-figure ARR, growing 50% month over month, with 300 syndicators and 3,000 investors. We’ve grown quickly because I am a syndicator myself. Having raised $20MM for my own deals, I know how painful it is to manually prepare Docusigns, send wire instructions and wrangle investors. I also happen to be friends with 2,000 other syndicators just like me needing a solution for managing their investors. I’m not just a syndicator. I spent most of my career as an engineering leader at Lyft, Twitter, and Amazon. $20K ARR per syndicator gives us a $2B TAM. Having achieved my own financial freedom through real estate investing, our mission is to serve all real estate investors and help them achieve financial freedom.

Castle

Castle manages rental homes using automation and on-demand labor.

Castle manages rental homes for landlords using automation and on-demand labor. We find tenants, collect rent, and coordinate maintenance, allowing owners to kick back, relax, and never worry about their rental properties again. Owners either have to deal with this whole mess themselves, or spend 10% of their rental income on a traditional property management company that requires constant supervision and is often incentivized to act against the owner’s best interest. There are 43 million rental units in the United States, and most of them are currently managed with some combination of faxes, mail, and unreturned voicemails on the landlord’s personal phone. Castle moves all of property management into a seamless online experience, providing owners with transparency, speed, and incredible customer service—plus huge cost savings over traditional management. Renters get great service and instant updates about important issues.
