A multi-discipline finance platform deploying capital, AI research, and institutional management across hospitality, multifamily, and fintech verticals.
Founded in 2022 and headquartered in Providence, Rhode Island, Calculus is a multi-discipline finance platform operating at the intersection of direct lending, artificial intelligence, and institutional asset management. With additional operations in London, United Kingdom, 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.
Co-Founder & CEO
Hugo Kaempfer co-founded Calculus in 2022 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, Hugo saw an opportunity to create a firm that could operate across traditional and emerging asset classes.
Under Hugo'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.
Hugo 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 (as of Q1 2026, unaudited).
We deploy capital where it matters most — bridging gaps in financial access, food security, and energy stability for communities that need it.
AI-powered alternative credit scoring and capital access for the unbanked and underserved communities worldwide. We believe access to capital is a fundamental right.
Supply-chain forecasting and development financing for agricultural infrastructure that feeds communities and strengthens local economies.
Financing and modeling for resilient energy systems, from renewables to grid-scale solutions that deliver reliable power to underserved markets.
Clear terms, honest communication, and full visibility into every transaction and decision.
Leveraging AI and quantitative research to stay ahead of markets and deliver smarter solutions.
We succeed when our clients and partners succeed. Every relationship is built on mutual value creation.
Rigorous compliance, ethical lending practices, and a commitment to doing right by every stakeholder.
We focus our capital deployment and advisory expertise across three core sectors where we have deep institutional knowledge.
Hotels, resorts, and short-term rental portfolios. Bridge and construction financing for experienced operators.
Apartment complexes, mixed-use developments, and workforce housing. Acquisition, rehab, and value-add strategies.
Financial technology platforms, alternative lending infrastructure, and embedded finance solutions.

Calculus is a multi-discipline finance platform co-founded in 2022 by Hugo Kaempfer in Portland, Maine. The firm operates through three integrated divisions: Calculus Lending (direct lending, loan syndication, and capital advisory), Calculus AI Labs (AI-powered underwriting, machine learning models, and quantitative research), and Calculus Management (institutional-grade discretionary portfolio management for accredited investors and family offices). Since inception, Calculus has deployed more than $150 million in capital across over 120 transactions and manages $40 million or more in assets under management.
The firm's mission centers on three impact-driven pillars: financial inclusion through AI-powered alternative credit scoring for the unbanked and underserved, food security through supply-chain forecasting and agricultural infrastructure financing, and energy stability through funding for resilient energy systems. Calculus serves borrowers, investors, and institutional partners across hospitality, multifamily real estate, and fintech verticals.

Calculus AI Labs, the firm's proprietary AI research division launched in 2022, develops machine learning models for deal sourcing, risk analytics, alternative credit scoring, and market forecasting. These AI capabilities power faster underwriting decisions, enabling term sheets within 48 hours and loan closings within two to four weeks. The platform bridges the gap between traditional capital markets and emerging opportunities that legacy institutions cannot efficiently address.
