Building Sustainable Value at the Intersection of Investors, Governments, and Contractors



A Message to Our Stakeholders Regarding COVID-19

As the devastating effects of the COVID-19 pandemic continue, we remain committed to serving the best needs of the investors, government agencies, and contractors that have allowed Brevet Capital Management to create effective financing solutions for the past 20 years. These relationships will become even more important in the months ahead as our economy moves towards recovery – and will again rely on government contractors to complete the projects that will produce critical supplies, accelerate logistics, and infrastructure – and put our nation back to work. We are proud of the role that private capital is playing to create a path to normalcy – and stand together with our partners to make it happen.–>

An Entrepreneurial Perspective Innovating Government Financing Solutions

Brevet Capital was founded in 1998 by Douglas Monticciolo, an entrepreneur and investment manager with deep data analytics and technology experience developed over three decades while providing credit financing and advisory services.

Unlike most direct lending funds, Brevet focuses on the government sector, where historically the risk of non-payment is low, but timing delays are common. The firm develops bespoke financing solutions to close these payment timing gaps.

Brevet employs a “finance as a service” approach by partnering with middle market companies who contract with government. In providing innovative financing and forward-looking advisory services, Brevet solves the companies’ complex financing needs, enabling them to win and complete contracts in a timely and efficient manner.

Brevet brings its 21 years of experience and best practices to each engagement, providing strategic counsel to government agencies and contractors to expedite the process for all parties.

Brevet Capital manages several government-focused investment funds for a diverse group of global investors, including public and private pension funds, endowments, foundations, insurance companies, sovereign entities, family offices, and high net worth individuals.

Impact Ingrained in Our Purpose

Brevet Capital is a leading financial advisor for government agencies facing complex financing situations. We view government as the ultimate impact investor. We drive positive social impact by creating innovative financing products and services that ultimately benefit the communities served. Brevet’s unique financing solutions support a wide range of U.S. federal, state and municipal government programs that promote the economic and social well-being of families, children, individuals, and entire communities.

Doug Monticciolo,

CEO, CIO and Co-Founder

Douglas Monticciolo is Chief Executive Officer, Chief Investment Officer and Co-Founder of Brevet Capital Management. He is an entrepreneur and investment manager with deep data analytics and technology experience developed over three decades while providing credit financing and advisory services.

Mr. Monticciolo founded Brevet Capital Management in 1998 and has established the firm as a leader in helping government agencies solve complex problems – and drive positive social impact – by creating innovative financing products and services. This “finance as a service” approach provides direct lending and other financing to private middle market companies that enable them to effectively serve the government sector as contractors – a low credit risk strategy with highly competitive barriers to entry.

Mr. Monticciolo’s years of experience working in start-up environments as a software entrepreneur and within asset-backed securities, fixed income, and investment banking helped him identify a gap in the market where traditional lenders failed to provide the innovative financing and forward-looking advisory services needed for the private contractors government contractors rely on to deliver services.

Mr. Monticciolo has a passion for technology and approaches investing and credit financing with a problem-solving mindset. He began his career at Goldman Sachs in the financial institution’s industry resource group where he specialized in investment banking and principal finance trading and helped create numerous serviced-marked products and services to address the unmet needs of clients. He later joined Lehman Brothers as a senior vice president in the company’s strategy group, a principal investment joint venture between investment banking and fixed income. He left Lehman Brothers to become director and co-head of asset-backed securities in North America at Deutsche Bank and head of proprietary fixed income in the merchant banking/principal finance group.

Mr. Monticciolo’s career took a turn from academics to finance when he was studying at Columbia University and working with Fischer Black, creator of the Black–Scholes model, on complex mathematical formulas. He was encouraged to apply his skills to financial problem-solving instead of academia and he decided to put aside his pursuit of a PhD to join Goldman Sachs.

Mr. Monticciolo received a Master of Engineering Sciences degree in Applied Mathematics from Columbia University. He graduated from the State University of New York at Stony Brook with an M.S. in Applied Mathematics and earned a B.S. in Applied Mathematics and Computer Science. Mr. Monticciolo is a Level III certified member of the National Association of Rocketry (NAR High Power Rocketry) and a member of the Randonneurs USA (long distance road biking organization). Mr. Monticciolo also coaches robotics and innovation and has led teams to numerous regional awards. He led one of his teams to a worldwide 2nd place finish (runner-up) for the FLL Global Innovation Award season sponsored by Edison Nation and XPRIZE Foundation, in cooperation with the United States Patent and Trademark Office (an agency of the United States Department of Commerce).

He currently serves on the Board of Directors of Hope for New York and is a Board Member of the Young Presidents Organization (YPO) Gotham Chapter.

Mr. Callahan’s extensive investment experience and background in public policy is a unique interdisciplinary blend of financial and government expertise that mirrors Brevet’s differentiated position in the marketplace. His keen financial analytical skills and understanding of funding priorities and procedures of government agencies directly influenced the founding principles of the firm and continues to support the success of Brevet’s investment strategy.

During his studies at Hamilton College, Mr. Callahan first appreciated the complexity of solving financial problems within the confines of public programs. His senior project involved a collaboration with the Federal Aviation Administration (FAA), New York State and the City of Syracuse to evaluate how to attract private sources of capital for improvements and the development of Syracuse Hancock International Airport.

Mr. Callahan began his finance career in 1994 at Chase Manhattan Bank as an M&A analyst and completed the firm’s ten-week credit training program. In 1996, he joined the company’s strategy group at Lehman Brothers, where he specialized in asset and balance sheet transactions for financial institutions with a focus on principal finance. Mr. Callahan and Douglas Monticciolo began their working relationship during their time at Lehman Brothers.

He later joined Mr. Monticciolo at Deutsche Bank, where Mr. Callahan was a founding member of the proprietary fixed income, merchant banking/principal finance group. At Deutsche Bank, Mr. Callahan managed transaction teams and was responsible for originating new mandates and developing exit strategies for portfolios.

Mr. Callahan graduated from Hamilton College with a B.A. in public policy and received honors for his senior project.
