Impact and emerging GPs to get a bold line of credit to streamline capital calls and accelerate dealflow. As an impact or emerging fund manager, let’s say you have hard-won investor commitments in writing. And let’s say you have a sweet deal or two ready to close. When should you call that capital from your LPs? Such operational questions can bedevil first, second and even third-time fund managers. Large and established asset managers, such as Ares Management or Blackstone, have access to designated lines of credit for capital calls that enable them to move quickly and keep their costs of capital low. Community Capital Management and Mission Driven Finance have teamed up on a new private credit strategy to meet the same short-term liquidity needs of impact and emerging fund managers. The joint venture, Bold Line Capital, will offer a lending facility to help GPs manage their capital calls, enabling them to call capital on a regular schedule while still moving on deals. The loans will be collateralized by those uncalled commitments from their investors. “We need more good emerging managers that are focused on improving people and planet to be able to scale to fund two, fund three and fund four. And this is one of the tools they need in their toolbox,” Mission Driven Finance’s David Lynn tells ImpactAlpha. The new initiative complements MDF’s Capital Partners Fund, which offers emerging managers bridge financing, working capital advances, deal warehousing and capital for co-investments.

  • Short duration. For institutional and other investors, Bold Line’s capital call lending facility is a short-duration private credit strategy that serves as a low-risk alternative to cash holdings with a clear impact thesis: to help impact and emerging managers succeed by giving them the same infrastructure and support that larger and more established managers enjoy – and LPs expect. The one-year tie-up is expected to deliver returns of 5.5%, increasing to 6% as more capital is deployed. The risk is low because, while the borrower is the fund manager, the loans are secured through agreements with the LPs themselves. Community Capital Management’s David Sand says the strategy can deliver long-term impact without a long-term commitment. “It works out really well to make a one-year commitment but know that one-year money is going to support managers and funds that are committing patient, long-term, catalytic capital in the impact arena.”
  • Bridging gaps. For Florida-based CCM, which manages more than $6 billion in fixed-income investments, the joint venture represents a move into the growing private-credit market. The strategy is available to CCM’s fixed-income separate account clients, who would lend their assets to Bold Line Capital. CCM’s Andy Kaufman said the strategy has soft commitments of about $25 million toward a near-term goal of $250 million. The first loans could go out in the next several weeks. Bold Line will extend lines of credit to US-based managers that have at least $30 million in signed commitments and have completed at least one capital call on their own. Bold Line expects the borrowers to include impact funds of funds and providers of impact private debt and private equity, as well as funds for venture real estate and affordable housing and employee ownership conversions. “We’re very aware of who the GPs will be, both in terms of their track record and their demographics,” Sand says.
  • Right to win. The 50/50 partners said Bold stands for “building opportunities and lowering deterrence.” Despite consistent evidence that first-time and emerging managers outperform their more established peers, many are being defeated by daunting fundraising and operational obstacles. Large asset managers that invest in emerging managers, like GCM Grosvenor and General Catalyst say they look for managers that have earned the “right to win” through their operational excellence (see, “CalPERS and CalSTRS find alpha in emerging managers”). The capital call line of credit could relieve GPs’ operational headaches by allowing them, for example, to issue a single capital call each quarter, which many LPs prefer. “They’re moving faster and quicker because they’re new and they’re innovative. Yet they’re not getting the tools they need to ultimately become as successful as we’d hope,” Kaufman says. “We want to make sure these new technologies and this positive theory of change is able to be supported, so it grows and brings the effective innovation that we hope to see.”

The Liist: GP Snapshots

This week’s updates. ImpactAlpha’s Liist of impact fund managers highlights strategies from more than 100 GPs launching strategies  in the market. Among the latest additions: three women-led firms advancing the circular economy, climate adaptation, and European innovation for climate and health. 

  • Archipelago Ventures in the UK invests in early-stage technologies curbing waste and boosting reuse of plastics, textiles, metals and other materials. Its ACE Fund is anchored by Lukas Walton’s Builders Vision. The firm structured its fund so that 25% of the carried interest is tied to its impact goals. More.
  • Tailwind Futures is working to drive climate adaptation by appealing to corporate climate goals and needs. The Berkeley, Calif.-based firm leverages corporate LPs to help portfolio companies innovate for corporate needs. The strategy readies the corporates as startups’ first clients and potential acquirers. Read on.
  • WakeUp Capital in Ireland is investing in early-stage hardware and software startups tackling climate and health challenges in Europe and the US. The Dublin-based firm emphasizes Ireland’s homegrown startups when possible. It also looks for companies focusing on underserved demographic groups. More.

Dealflow: Green Buildings

Nuveen raises another $785 million for sustainable commercial real estate strategy. The $1.3 trillion investment management arm of TIAA secured the capital for its third C-PACE Lending Fund. C-PACE is a lending program enabled by state governments that allows building owners and developers to secure upfront financing for green construction or energy upgrades, then repay the debt over time through “benefit assessments” on their property’s tax bill (see related, “Calvert Impact rolls out second ‘cut carbon note’ for green building upgrades“). Nuveen’s lending fund allows institutional investors to invest in C-PACE loans and securitizations. Nuveen did not disclose the LPs in the fund.

  • Strategic evolution. The new capital brings Nuveen’s C-PACE assets under management to $6 billion. It launched a dedicated C-PACE fund strategy in 2017 and became one of the first institutions to securitize C-PACE loans. Nuveen says its portfolio last year alone conserved more than 460 million gallons of water and 585 megawatt-hours of energy and created 2,100 new housing units. Last year, Nuveen partnered with Canada’s CDPQ on a $600 million financing initiative that combines C-PACE lending with senior bridge and construction loans for green commercial real estate development.

Signals: LP = Leadership Potential

Without oil, Rockefeller Brothers Fund demonstrates mission-aligned outperformance. The Rockefeller Brothers Fund, the family foundation of the heirs of Standard Oil’s founder, exited its fossil fuels investments a decade ago. Since then, the leaders of the $1.4 billion endowment have sought to prove that mission-aligned investing can deliver strong returns and lower risk. The results are in: between 2014 to 2024, the fund delivered an annualized return of 7.76%, outperforming its benchmark by more than 100 basis points, or one percentage point, each year, with 27% less volatility. The results are detailed in “Returns, risk and responsibility: How the Rockefeller Brothers Fund invests for long-term value and the public good,” produced with The Investment Integration Project. The report arrives as RBF navigates a leadership transition and a volatile political climate for ESG investing. “While we are very excited about what we’ve achieved, we’re also quite sober about how hard it is going to be to continue down this path and continue achieving the same kinds of results,” Stephen Heintz, the foundation’s president, tells ImpactAlpha. Heintz, who has led Rockefeller Brothers Fund since 2001, plans to step down next year. 

  • Systems level thinking. As its work on climate, democracy and equity increasingly overlapped, RBF embraced TIIP’s framework for investors to shape the social, environmental and financial systems that underpin long-term value. The approach goes beyond managing individual holdings to deploying tools such as shareholder engagement, proxy voting, public policy advocacy and ecosystem building to drive systemic change. “We are seeing systems failure, and those failures have profound implications,” says Heintz. “Unless we are thinking at a systems level and thinking across systems, we will not get to the place we need to be.” The report caps Heintz’s career at RBF, during which the fund more than doubled its assets to $1.4 billion and helped shape a new era of mission-driven endowment investing. “I’m hopeful that a new leader will bring new ideas,” he says, “and also a different experience that can accelerate and advance this work.”
