A multi-discipline finance platform deploying capital, AI research, and institutional management across hospitality, multifamily, and fintech verticals.
Founded in 2020 and headquartered in Boston, Massachusetts, Calculus is a multi-discipline finance platform operating at the intersection of direct lending, artificial intelligence, and institutional asset management. With additional operations in Windsor, Connecticut, we serve a national footprint of borrowers, investors, and institutional partners.
Our platform is purpose-built to bridge the gap between traditional capital markets and emerging opportunities in hospitality, multifamily real estate, and fintech assets — delivering speed, transparency, and precision that legacy institutions cannot match.
Our integrated platform delivers end-to-end financial solutions through three specialized divisions.
Our direct lending and private credit arm. We originate, underwrite, and distribute capital across real estate, hospitality, and fintech verticals.
Our proprietary AI research division. We build machine learning models and quantitative tools that power smarter capital allocation decisions.
Institutional-grade discretionary portfolio management and private investment vehicles for accredited investors and family offices.
Founder & CEO
Sean Grady founded Calculus in 2020 with a singular vision: to build a finance platform that combines institutional-grade capital deployment with cutting-edge AI research. With a background spanning private credit, quantitative analysis, and fintech innovation, Sean saw an opportunity to create a firm that could operate across traditional and emerging asset classes.
Under Sean's leadership, Calculus has grown from a boutique lending operation to a multi-discipline platform managing over $40MM in assets, deploying more than $150M in capital, and closing over 120 deals across hospitality, multifamily, and fintech verticals.
Sean brings a unique blend of finance, technology, and social impact expertise to every engagement. Under his leadership, Calculus has deployed over $150M in capital across 120+ transactions.
