Constantinople & Vallone Consulting

What Constantinople & Vallone Consulting does

Constantinople & Vallone Consulting LLC is a privately held boutique government relations and strategic consulting firm headquartered at 233 Broadway in the Woolworth Building, New York City. Founded by Tony Constantinople and former New York City Council Speaker Peter Vallone Sr. (1986–2001), the firm operates with approximately 19 team members organized into five Partners, three Senior Vice Presidents, two Vice Presidents, a Chief Operating Officer, an Office and Client Engagement Manager, a Compliance Manager/Accountant, a Director of Compliance, three Associates, and interns. The practice is rooted in Vallone Sr.'s legacy of consensus-based governance and is staffed by alumni of senior government roles, including former HPD, NYC Landmarks Preservation Commission, the Mayor's Office of City Legislative Affairs, the Governor's office, and Congress, providing the firm with established relationships at City, State, and Federal levels.

The firm delivers customized advisory services across seven verticals: Real Estate, Land Use, and Construction; Nonprofits; Energy and Environment; Education; Technology; Business Strategy & Public Affairs; and Labor and Workforce. Service offerings include legislative advocacy, regulatory navigation, land use and zoning approvals, public funding and budget appropriations, community engagement, crisis communication, and procurement guidance. The firm does not sell technology products; its deliverables are human-delivered strategic counsel and direct government engagement. Client outcomes documented in public sources include $200 million in state and city funding secured for Kingsbridge Armory, 1,340 housing units (including 335 affordable) unlocked through Halletts North rezoning, and seven-figure nonprofit allocations including $1.2 million for New York Edge and $995,500 for NYJTL.

Revenue derives from professional services fees, retainers, and project-based engagements tailored to client objectives, with multi-year contract cadences implied by the relationship-driven nature of the work. The firm has no disclosed funding rounds, no parent company, and no external investors; ownership remains with the founding families. Go-to-market is reputation- and referral-driven, supported by continuous recognition in City & State NY Power Lists and trade publications, a website organized by service line, and LinkedIn presence for senior team members. The client roster spans large enterprises (Lyft, Walgreens, T-Mobile, TD Bank, Qualtrics, Waste Management, College Board), real estate developers (Gilbane, Fairstead, Maddd Equities), clean energy operators (NineDot Energy), and a growing base of nonprofits (New York Edge, YAI, Lower East Side Ecology Center, You Gotta Believe!).

Direct peers

• Marathon Strategies: NYC-based integrated public affairs, government relations, and strategic communications firm. Comparable in offering (GR + public affairs + crisis communications) and enterprise-client focus.
• Ostroff Associates: Albany-focused government relations firm representing corporate, trade association, and nonprofit clients before NY State government. Comparable in size and practice mix to C&V's Albany-facing work.
• Bolton-St Johns: Established NYC and Albany government-relations firm focused on real estate, land use, and affordable housing, mirroring C&V's largest practice area and client overlap.
• Kasirer: Leading NYC-based government relations and strategic consulting firm serving real estate, nonprofit, and corporate clients across City and State government. Closest direct competitor to C&V in NYC land use, nonprofit, and public-affairs work.
• Hinman Straub: Albany-based government-relations and lobbying firm with cross-vertical practice (healthcare, energy, insurance, education). Comparable NY State government focus and service model.
• Park Strategies: NYC and Albany government relations and business-strategy firm serving a broad cross-section of industries. Comparable in vertical breadth and senior-partner-led operating model.
• Brown & Weinraub Advisors: Albany-based government relations and strategic advisory firm representing healthcare, education, energy, and real-estate clients. Comparable in service mix and State-level orientation to C&V's Albany practice.

Broad incumbents

• Mercury: National public-strategy and government-relations firm with state-federal integrated capabilities. Larger incumbent offering multi-state, multi-issue mandates that C&V's NYC-focused boutique model cannot match at scale.
• Cornerstone Government Affairs: National bipartisan government-affairs firm with offices in Washington and multiple state capitals. Represents the multi-state, multi-jurisdiction competition that C&V does not directly contest.
• Tusk Strategy: National government-relations, strategic communications, and political consulting firm. Competes for enterprise clients needing integrated state, federal, and crisis work that exceeds C&V's geographic footprint.
