Arthur is a CPA who has spent his career building and using the technology behind partnership tax, first as a practitioner on real estate partnerships, multi-tier funds, and REITs, then over a decade at KPMG US leading the development of the firm's end-to-end partnership tax platform, used by 4,000+ professionals and their clients. Most recently, he led Tax Technology Services at CohnReznick, where he saw firsthand what firms are up against: the same problems the Big 4 had quietly solved internally a decade earlier, without the budget to build the same way out.
Who We Are
Built by practitioners, for practitioners.
We spent our careers in partnership tax, preparing tax returns and building the software to do it, and learned that software is only useful if it handles the hard parts. Complexity seems to show up on every return, whether in 704(c) layers, book-to-tax adjustments, target capital allocations, or multi-tier structures. When the software cannot handle the “edge cases”, the practitioner ends up piecing the return together across different tools or falling back to disconnected manual workbooks. Cascade is built for exactly those returns, and designed so a practitioner will want to use it: the whole structure in one place, math you can trace, and an AI agent that does the manual work so that their time goes to review.
Founders
Greg has spent two decades on partnership tax: preparing and reviewing returns, advising on M&A transactions, and executing tax equity financings. Over the past decade at Marathon Capital, he raised tax equity financing for renewable energy projects, with a heavy focus on complex capital account and tax basis modeling. He spent his first decade in public accounting at RSM US and KPMG US, focusing on tax compliance for real estate partnerships, multi-tier funds, and high net worth individuals.
