Developers Collaborative

What Developers Collaborative does

Developers Collaborative is a Portland, Maine-based for-profit real estate development firm founded in 2010 by Kevin Bunker that develops affordable, workforce, market-rate, and senior housing alongside commercial and historic preservation projects across at least 10 Maine communities. Its portfolio spans ~250+ owned units across product lines including the 208-bed Homeless Services Center in Portland, Rumery Lofts (38 units, adaptive reuse of a 1928 building), Peasley Park (49-unit senior housing, Rockland), Congress Square Commons (48-unit mixed-income, Belfast), Riverbrook Apartments (30 units, South Portland), Griffin Road Apartments (55+ in Scarborough), The Motherhouse at Stevens Square, Freedom Place (transitional housing), and the proposed McLain School (44 units) and former Augusta police station (~100 units) developments. Technical differentiators center on LEED Gold-certified construction, passive-house-level envelopes, fossil-fuel-free operations with rooftop solar arrays (e.g., 107.8 kW at the Homeless Services Center, 175 MWh/year at Congress Square Commons), and historic preservation expertise rather than any software or AI capability.

The business model operates across three revenue streams: (1) recurring residential rental income from owned and stabilized properties (market rate units at $1,750–$2,600/month, workforce at $1,445–$1,917/month, affordable up to 80% AMI), (2) development fees earned on projects structured for municipalities, nonprofits, and private clients using complex multi-source financing (LIHTC, HOME, HTF, CDBG, TIF, project-based vouchers, construction loans from Gorham Savings, NBT Bank, Maine Community Bank, Evernorth, and CEI), and (3) ongoing property and asset management fees through the wholly-owned DC Management subsidiary, which also serves select third-party Maine clients. Go-to-market mixes direct-to-consumer leasing (DC Management, dcmaine.com, 207-772-3225) with enterprise/B2G development sales to municipal partners and housing authorities. Customers include individual renters across senior, workforce, and market-rate segments; government clients (City of Portland, Belfast, Augusta, Auburn Housing Authority, MaineHousing, Maine DECD); and social service partners such as Spurwink Services and Volunteers of America of Northern New England that provide on-site supportive services.

Operational leadership consists of Founder Kevin Bunker, CFO/COO Eric Boucher (appointed March 2026, previously 15+ years as EVP/CFO/COO at Avesta Housing), and COO Amanda Bartlett. The firm is privately held with no disclosed external institutional investors, and its value proposition rests on combining a community-and-listening-based planning approach with end-to-end execution from site selection through long-term property management—supported by deep municipal relationships, regulatory expertise in affordable housing finance, and recognition as Maine's leading developer of neighborhood-enhancing projects.

Direct peers

• Avesta Housing: Maine's largest affordable housing nonprofit, directly comparable as both developer and operator of affordable multifamily housing across Maine. Strongly relevant because Developers Collaborative's new CFO/COO Eric Boucher previously spent 15+ years as Avesta's EVP/CFO/COO, indicating direct familiarity and likely overlap in markets, funding sources, and tenant segments.
• Wishrock Housing Group: Portland, Maine-based real estate development and property management organization focused on affordable and mixed-income housing. Directly comparable in geographic market (Portland metro), product type (affordable multifamily), and mission-driven approach.
• Community Housing of Maine: Maine-based nonprofit developer and manager of affordable rental housing serving low-income households, including supportive housing for vulnerable populations. Closely comparable to Developers Collaborative's affordable housing and Housing First segments.
• The Caleb Group: Maine nonprofit developer of affordable housing serving people with intellectual disabilities and other vulnerable populations. Comparable in operating geography (Maine), affordable housing focus, and reliance on LIHTC and state housing finance.
• Dakota Partners: New England-based affordable housing development and consulting firm specializing in LIHTC-financed multifamily projects. Comparable in product type, funding model (LIHTC-heavy), and regional New England focus.

Broad incumbents

• Pennrose: Multi-state affordable housing developer and property manager with significant Northeast presence. Comparable product mix (affordable, workforce, mixed-use, mixed-income) and capital-stack structuring capabilities, though at substantially larger scale and broader geographic footprint.
• Beacon Communities: Northeast-based affordable and mixed-income housing developer and manager. Comparable in product type (workforce, affordable, mixed-use) and use of LIHTC and public financing, with broader geographic footprint and larger institutional capacity.
• WinnCompanies: Boston-based multifamily developer, owner, and manager with substantial New England affordable and market-rate portfolio. Comparable in integrated development-plus-property-management model, though at much larger scale and national footprint.
• The Community Builders: Northeast-based nonprofit developer of affordable and mixed-income housing. Comparable mission-driven model, LIHTC-financed multifamily product, and integration of supportive services, though with significantly larger portfolio and broader geographic reach.

Emerging players

• Preservation of Affordable Housing (POAH): National nonprofit focused on preserving and developing affordable rental housing. Comparable mission and product type, particularly relevant for Developers Collaborative's adaptive reuse and historic preservation activities; operates at larger scale but with similar values-driven positioning.
