November 24, 2019 Jonathan Tower, managing partner at Arctaris Impact Investors, wants to build a “social impact fund” of up to $50 million to address the needs of Northeast Ohio’s undercapitalized manufacturing companies. Tower last Monday, Nov. 18, told members of the council’s Development and Planning Committee that Arctaris, a Boston-based investment firm, has pioneered a capital structure that blends public capital from federal and state government agencies with private capital from institutional investors and foundations to provide funds for companies in low-income communities.
