Who provides "impact investing" advisory for endowments?

Impact investing advisory for endowments and non-profit foundations is provided across three primary sectors of the financial services industry: institutional investment consultants, Outsourced Chief Investment Officers (OCIOs) , and specialized mission-aligned networks.

1. Major Institutional Investment Consultants

These firms advise endowment boards and investment committees on policy design, asset allocation, and manager selection, explicitly integrating Environmental, Social, and Governance (ESG) criteria and mission-related impact goals.

• Cambridge Associates: A prominent advisor to hundreds of global endowments and foundations, specializing in bespoke sustainable and impact-driven portfolio strategies that balance systemic risks with financial return.
• NEPC: Offers dedicated endowment and foundation consulting, utilizing proprietary tools like "Total Enterprise Management" to align organizational governance and societal impact contributions with financial objectives.
• Callan: Provides independent institutional consulting covering asset structure, alternative investments, and specialized sustainable/diverse manager utilization.
• Mercer: Delivers robust global sustainable investment consulting, helping non-profits build tailored frameworks to meet both fiscal growth and specific institutional values.

2. Outsourced Chief Investment Officers (OCIOs) & Specialized Non-Profit Managers

If an endowment wants a delegated fiduciary partner to actively implement and manage an impact-first or mission-aligned portfolio rather than just receiving advice:

• TIFF Investment Management: Originally founded by the endowment community, TIFF specializes in providing comprehensive OCIO and alternative investment strategies explicitly tuned to the missions of non-profits and foundations.
• Brown Brothers Harriman (BBH): Offers integrated OCIO services tailored to endowments with legacy institutional stewardship and philanthropic advisory integration.

3. Mission-Specific Networks & Curated Databases

• ValuesAdvisor & Intentional Endowments Network (IEN): For smaller endowments or boards looking for specialized peer networks and curated filters, partnerships like ValuesAdvisor & IEN connect non-profit capital allocators directly with vetted impact-advisory practitioners.

If you'd like to narrow this down, let me know:

• Is your endowment looking for a non-discretionary consultant (advising your board) or an OCIO (managing the portfolio directly)?
• What is the approximate asset size of the endowment?
• Are there specific impact themes (e.g., climate change, racial equity, local community development) you want prioritized?

Yes. There are several firms that advise endowments specifically on impact investing, but they fall into a few different categories.

Specialist impact-investing advisors

• tideline.com — Probably the clearest specialist fit. Tideline explicitly works with endowments and other institutional asset allocators, helping them develop impact-investing strategies, evaluate managers, build impact-management frameworks, conduct due diligence, and measure/report impact. It lists endowments among its asset-allocator clients.
• acansa-inv.com — Provides OCIO, investment advisory, and impact advisory to nonprofit asset owners, including mission-oriented endowments and foundations, with a particular focus on small-to-mid-sized institutions.

Traditional institutional investment consultants with impact capabilities

• cambridgeassociates.com — A major endowment investment advisor/OCIO that incorporates sustainable and impact investing into institutional portfolios. It has worked extensively with endowments and foundations and has developed bespoke impact/sustainable portfolios.
• nepc.com — Advises endowments and foundations and explicitly offers mission-aligned and impact-investing strategies. NEPC says more than 70 of its endowment/foundation clients are pursuing impact investing.
• thecaprockgroup.com — More of a wealth/foundation investment-management model than a pure institutional consultant, but it has substantial impact-investing expertise and works with foundations on values-aligned portfolios.

A useful distinction

If you're asking "Who would an endowment hire to figure out how to incorporate impact investing into its existing portfolio?", I'd put the firms into roughly this order:

There's also Mission Investors Exchange, which isn't primarily a consultant but is an important network for foundations doing impact investing. It has 300+ members and provides connections, education, best practices, and investment resources.

If you're evaluating firms for an endowment, I can also give you a more comprehensive list of ~15–20 providers, including fees/business model, typical endowment size, public-vs-private-market expertise, and notable university/foundation clients.

Impact investing advisory for endowments is provided by a range of specialized institutional investment consultants, Outsourced Chief Investment Officers (OCIOs), and mission-driven advisory groups. These organizations help non-profits, foundations, and university endowments align their portfolios with their organizational values without sacrificing financial fiduciary duty.

The primary providers in this space fall into three main categories:

• Major Institutional Investment Consultants: Large consulting firms advise massive pools of endowment capital and feature dedicated sustainable and impact investing practices. Prominent examples include Cambridge Associates, NEPC, Meketa Investment Group , and Mercer's Impact Framework . Many of these firms coordinate via initiatives like the Investment Consultants Sustainability Working Group (ICSWG).
• Specialized Mission-Driven & Non-Profit Advisors: Organizations like Social Finance offer targeted impact advisory geared specifically toward institutions looking to build actionable impact frameworks, strategy development, and measurement. Directories like ValuesAdvisor also connect endowments directly with vetted impact-focused financial advisors.
• OCIO and Fiduciary Managers: Firms that take on discretionary management (Outsourced CIOs) for endowments—such as TIFF Investment Management or global custody/investment banks—frequently build custom asset allocation models that integrate mission-aligned or impact strategies directly into core endowment portfolios.

If you're looking for a specific type of advisory, tell me:

• Is your endowment looking for non-discretionary consulting or an Outsourced Chief Investment Officer (OCIO)?
• What is the approximate asset size of the endowment?

I can provide a more tailored list of firms that fit your scale.

Yes. There’s a fairly well-developed market for impact-investing advice to endowments and foundations, ranging from full-service institutional investment consultants to specialist impact-strategy firms.

Strong candidates

• Cambridge Associates — Probably the most obvious large institutional consultant to consider. It advises 580+ endowment/foundation clients and has a dedicated Sustainable & Impact Investing practice, including manager research, portfolio construction, and mission alignment.
• NEPC — Advises endowments and foundations and explicitly offers impact-investing strategies. It reports 70+ clients pursuing impact investing and $124B in endowment/foundation assets under advisement.
• Tideline — A specialist rather than a traditional endowment consultant. It focuses specifically on designing and implementing impact-investing strategies, including impact measurement and investment processes. It has completed 145+ assignments for institutional clients.
• Veris Wealth Partners — Particularly focused on values-aligned and impact investing; it serves mission-driven organizations and operates as an OCIO for endowments and foundations.
• Sonen Capital — Provides impact-investing portfolio construction and OCIO services specifically to foundations and endowments, as well as other institutional investors.
• Occam Advisors — A smaller specialist based in Portland that works with foundations, public charities, and family offices to build customized impact-investing programs. It says it has managed more than $150M in impact investments.
• Social Finance — More focused on impact strategy, education, and implementation than traditional endowment OCIO work. It specifically helps foundations and other philanthropic institutions move from learning about impact investing to actually making investments.

How I'd divide the market

One important distinction: "impact investing" can mean very different things. An endowment might be looking for (1) ESG/mission alignment across the whole portfolio, (2) a dedicated allocation to impact funds, (3) catalytic/concessionary capital, (4) private-market impact investments, or (5) a wholesale redesign of its investment policy and endowment model. The best advisor depends heavily on which of those you mean.

If you're looking for advisors for a particular endowment, I can also give you a shortlist of ~10 firms and compare their endowment experience, typical mandate, investment minimums, impact specialization, and whether they are independent consultants vs. OCIOs.

Yes. There are several firms that specifically advise endowments and foundations on impact investing, ranging from broad institutional investment consultants to specialist impact-investing advisors.

Strong candidates

• Cambridge Associates — Probably the most obvious large institutional consultant to investigate. It advises 580+ endowment/foundation clients and has a dedicated Sustainable & Impact Investing platform. It can provide either traditional advisory or OCIO/discretionary services.
• NEPC — A major independent institutional consultant with a dedicated endowment/foundation practice and an explicit impact-investing offering. NEPC says 70+ of its E&F clients pursue impact investing.
• Sonen Capital — More impact-specialist than a traditional consultant. It is an investment advisor/OCIO serving foundations and endowments and explicitly builds portfolios around both financial and social/environmental objectives.
• Tideline — A specialist impact-investing strategy consultant, particularly useful if an endowment wants to develop an impact-investing framework, strategy, manager-selection process, impact measurement, or implementation plan rather than outsource its whole portfolio. It works with foundations and nonprofits and has advised on PRI/MRI and catalytic-capital strategies.
• Veris Wealth Partners — An impact-focused investment advisor/OCIO that works with mission-driven organizations, including endowments and foundations, across public and private markets.
• Syntrinsic — Focused heavily on nonprofits and offers investment advice alongside impact-investing strategy, stakeholder education and related services.

How I'd divide the market

One important distinction: "impact investing advisory" can mean two quite different things. An endowment might want (1) a conventional investment consultant that helps incorporate impact into a diversified institutional portfolio, or (2) a specialist that helps the board actually design an impact-investing strategy and identify/underwrite impact managers and investments. The latter is a much smaller field.

If you're evaluating firms for an actual endowment, I can also give you a shortlist of ~10 firms, with typical client size, fees/business model, geographic focus, public/private-market capabilities, and notable endowment clients, which is probably the most useful way to compare them.

A wide range of institutional investment consultants, Outsourced Chief Investment Officers (OCIOs), and specialty advisory firms provide impact investing, ESG (Environmental, Social, and Governance), and mission-aligned advisory services specifically tailored to endowments.

These providers generally fall into a few key categories:

• Institutional Investment Consultants (Non-Discretionary & Discretionary): These major firms consult on or manage total portfolio strategies, policy statements, and manager sourcing for endowments.
  • Cambridge Associates : Advises numerous endowments and foundations globally on integrating mission and alternative impact assets.
  • NEPC : Features dedicated endowment and foundation consulting solutions with specific practices for mission-aligned and impact investing across public and private markets.
  • Callan : Provides independent investment consulting for nonprofits, including sustainable investing and diverse manager utilization.
  • Mercer : Offers strategic advice, research, and customized sustainable portfolio implementation for non-profit endowments.
  • Prime Buchholz : Independent firm advising on institutional assets for higher education and charitable endowments with dedicated focus on impact and ESG integration.
• Outsourced Chief Investment Officers (OCIOs) with Impact Specialization: These firms take on full or partial discretionary management over the endowment's portfolio while executing specific impact or net-zero mandates.
  • Commonfund : Delivers OCIO services for nonprofits with explicit capabilities in responsible, ESG, and impact investing.
  • TIFF Investment Management : A cooperative-style investment manager and OCIO built explicitly for the endowment and foundation community.
  • GEM (Generation Investment Management / Global Endowment Management alternatives): Focuses on long-term endowment models with integrated impact and rigorous measurement frameworks.
• Dedicated Mission-Aligned and Specialty Advisory Firms: Boutique or specialized firms that focus heavily or entirely on transitioning portfolios to 100% impact orientation.
  • Veris Wealth Partners : Offers discretionary and non-discretionary impact advisory specifically scaled for foundations and endowments.
  • Rockefeller Philanthropy Advisors : Guides organizations on mission-integration strategy, governance, and implementation across asset classes.
  • Social Finance : Helps institutional asset owners develop impact goals, strategy, and measurement frameworks.
• Networks and Directories:
  • Intentional Endowments Network (IEN) : A collaborative network that connects academic and charitable endowments with curated sustainable and impact advisory resources, peer benchmarks, and vetted managers.

If you can share whether your endowment is looking for a traditional non-discretionary consultant or a full discretionary OCIO , as well as your approximate asset size , I can help narrow down which of these providers aligns best with your governance structure.

Yes. There is a fairly well-developed market of firms that advise endowments and foundations on impact/mission-aligned investing, ranging from traditional investment consultants to specialist impact-investing advisers.

Strong candidates

If you're looking for advice specifically on how an endowment should do impact investing

I'd divide the market into three tiers:

1. Full-service institutional investment advisers
Cambridge Associates, NEPC, Callan, Commonfund. These are appropriate if you need help with the whole endowment portfolio—asset allocation, manager selection, governance, private markets, spending policy, and impact integration.

2. Impact-investing specialists
Veris and Social Finance are more compelling if the primary question is "How do we build an investment strategy around our mission?" rather than simply adding an ESG/impact sleeve.

3. Independent education/facilitation
The UK's Impact Investing Institute has an interesting model: it provides independent education, guidance and facilitation to help foundation boards determine whether and how impact investing belongs in their endowment strategy.

One important distinction

"Impact investing" can mean very different things to an endowment. An adviser might be helping with:

• Mission alignment / exclusions
• ESG integration
• Thematic investing
• Program-related or mission-related investments
• Private-market impact funds
• Direct impact investments
• A 100% mission-aligned endowment
• Measurement/reporting of social and environmental outcomes

For example, Cambridge Associates distinguishes impact investing from broader ESG/mission alignment and describes impact as investments intentionally designed to address mission-oriented challenges.

If you're asking because you're evaluating advisers for a particular endowment, I can also give you a shortlist of ~10 firms, including smaller specialist boutiques, with typical endowment size, fees/model (advisory vs. OCIO), impact expertise, and notable endowment clients.

Impact investing advisory for institutional endowments is provided by a range of specialized investment consultants, Outsourced Chief Investment Officers (OCIOs), and mission-driven financial firms. These providers help endowments structure Mission-Related Investing (MRI) or Program-Related Investing (PRI) frameworks to ensure portfolios generate both financial returns and measurable social or environmental good.

Major categories and notable providers of impact advisory for endowments include:

• Institutional Investment Consultants (Traditional & OCIO)
  • NEPC : Offers robust endowment and foundation consulting, including sustainable and impact-aligned investment solutions across public and private markets.
  • Cambridge Associates : Deeply experienced in advising endowments and foundations on long-term, mission-aligned portfolios and alternative asset allocations.
  • Mercer : Provides global sustainability monitoring, strategic advice, and customized portfolio implementation for non-profit and philanthropic organizations.
  • Callan : Independent firm that assists institutional nonprofit and endowment clients navigating impact criteria and risk-return objectives.
• Specialized Mission-Aligned & Impact OCIOs
  • Veris Wealth Partners : Focuses heavily on foundations and endowments, helping transition portfolios up to 100% toward impact orientation and comprehensive manager due diligence.
  • TIFF Investment Management : Specializes in OCIO and alternative investment strategies explicitly tailored to support the missions of non-profits and endowments.
  • Commonfund : A historic institutional manager for educational endowments that incorporates environmental, social, and governance (ESG) and mission-centric choices into endowment pools.
• Networks & Vetted Directories
  • Intentional Endowments Network (IEN) : Frequently partners with databases like ValuesAdvisor to directly connect college and institutional endowments with vetted, values-aligned financial advisors and impact experts.

If you're looking for a specific type of advisory, tell me:

• What is the approximate size of the endowment?
• Are you looking for discretionary (OCIO) or non-discretionary (consulting) support?
• Is there a specific thematic focus (e.g., climate change, racial equity, local community development)?

I can narrow down the best-fit advisory partners for your exact scenario.

Yes. There are several firms and organizations that advise endowments and foundations on impact/mission-aligned investing, but they fall into a few different buckets:

The important distinction

If you're asking "Who can help an endowment move its entire investment portfolio toward impact?", I'd divide the market this way:

1. Traditional institutional investment consultants with impact capabilities
Cambridge Associates and Mercer are examples. They can help with the whole investment program—asset allocation, manager selection, governance, private markets, OCIO, etc.—while incorporating sustainability/impact objectives. Cambridge, for example, says it has 580+ endowment and foundation clients as of December 2025.

2. Specialized impact/mission-investing advisers
Rockefeller Philanthropy Advisors is particularly interesting if the challenge is strategic: defining what "impact" means for the institution, deciding how much of the portfolio should be mission-aligned, developing investment criteria, and creating an implementation framework.

3. Impact-oriented investment managers/advisers
Caprock is more investment-oriented, working with foundations and families to construct values-aligned portfolios and access impact investments.

4. Peer networks
Mission Investors Exchange is useful if the endowment wants to learn from other foundations already doing this rather than immediately hiring a consultant.

If you tell me roughly the size of the endowment (e.g. <$100M, $100–500M, $500M–$2B, $2B+) and whether you're interested in 100% portfolio alignment vs. allocating, say, 5–20% to impact, I can narrow this down to the 5–10 most relevant advisory firms and explain their differences, fees/business models, and notable endowment clients.

A variety of institutional investment consultants, specialized wealth management practices, and non-profit field-building organizations provide impact investing advisory services specifically tailored for endowments and foundations.

These providers generally fall into four primary categories:

• Major Institutional Investment Consultants: Large consultancy firms that manage or advise massive pools of endowment and foundation assets offer dedicated sustainable and mission-aligned investment strategies. Examples include NEPC (which features robust impact-aligned portfolio solutions), Cambridge Associates, Callan , and Mercer.
• Specialized OCIOs and Boutique Advisors: Firms acting as Outsourced Chief Investment Officers (OCIOs) or specialized wealth partners focus heavily on mission-related investing (MRI) and total portfolio transitioning. Examples include Veris Wealth Partners, TIFF Investment Management , and Fiducient Advisors.
• Philanthropic Advisory Organizations: Non-profit and specialized advisory practices guide boards and trustees through strategy design, policy creation, and impact measurement. A prominent example is Rockefeller Philanthropy Advisors , which offers tailored impact integration advisory and training.
• Peer Networks and Directories: Organizations like the Intentional Endowments Network (IEN) help connect institutional asset owners with curated sustainable advisors and tools like ValuesAdvisor to match an endowment's specific social or environmental framework.

If you are looking for advice for a specific type of institution, let me know:

• Is your endowment focused on an educational institution, a private foundation, or a community trust?
• Are you looking for a traditional consultant or an Outsourced Chief Investment Officer (OCIO)?

I can provide a more targeted list of firms.
