Committed to advancing the common good.

We are pioneers, market-makers, social entrepreneurs, tech4good nerds and impact measurement geeks committed to advancing the common good by funding verified impact and supporting the organizations delivering it.

Positively disrupting how impact is achieved and funded

We believe that most impact is underrecognized and undervalued. We believe that impact can be measured, can be verified, and can be delivered as a unique blockchain token – a Verified Impact AssetTM – that can change the paradigm of how we solve the world’s greatest problems.

We didn’t set out to build a marketplace, but we saw the clear need. There was a massive gap of infrastructure to measure, value, verify and fund impact. Social Impact Bonds, Results-based Financing programs and the Carbon Markets gave us a vision of what could be, so we started building it. But a marketplace is only as effective as those who participate so we invite those with a passion for funding results to join us and help us build a paradigm-shifting marketplace for the common good. 

Our Team

We’ve had the opportunity to build high impact companies with talent across the globe for the last 20 years.

Our Advisors are true world changers in sustainability, innovation, technology and strategy.

Greg is as much at home in a village in East Africa as he is in the mountains of Park City, Utah where he grew up. At age 23, he stepped off the airplane in Nairobi as an under-qualified but eager co-founder of The Paradigm Project, a last-mile clean energy distribution business. After 10 years of launching and operating social enterprises across East Africa and earning a Forbes 30 under 30 honoree, seeing opportunity in emerging and new markets has become his norm. Building diverse teams to deliver social, environmental, and economic impact has been the avenue to achieve Greg’s long-standing desire to reach underserved communities.

Our manifesto

Collectively, we need to up our game if we’re serious about achieving peace and prosperity for all. That’s why we’re changing the way human flourishing is valued and achieved. So we focus not on sustainability practices, but on demonstrated performance.

Where real change is delivered in the form of a blockchain token: transferable, permanently, transparently, and verifiably connected to the real story, and the individuals in that story.

Not as commodities, or an offset to bad behavior.

Because like people, a story of lasting transformation can never be a commodity. So we serve the people in these stories, and all the new stories that are possible - because verified outcomes can finally reflect their true value.

Driven by our 10 principles

Common Good Marketplace thrives by a common commitment to the principles that ensure it equitably benefits all stakeholders.

1. Credibility

Impact Quantification and Valuation standards used by CGM have reached considerable consensus that the standard is valuable and does in fact achieve its sustainability objectives. The standard cannot be new, unproven or unutilized.

2. Measure Impact Outcomes

Impact including both positive and negative, intended and unintended to determine the net impact. Impact be measured in line with, or incorporate, the Impact Management Project’s 5 Dimensions of impact which include measurement of
1. what is the impact,
2. who is affected by the impact,
3. how much impact is created in depth and duration,
4. the contribution of the developer,
5. the risk of the intended impact not occurring. 

3. Stakeholder Engagement

The stakeholders surrounding a CGM-certified project activity must be sufficiently engaged and consulted to maximize impact, reduce unintended negative outcomes, optimize program design and implementation, support verification of impact achieved, and improve the project during the evaluation period.

4. Social Value

Impact has positive economic value that can and should be measured. Each Impact Asset valuation must incorporate both the positive and negative value of the project’s impacts, including the practitioner, project developer or organization’s negative social and/or environmental impacts. An impact recipient (whether customer, beneficiary or stakeholder) must estimate the relative economic value of the impact they experience, and this value and all applicable assumptions must be incorporated in the overall calculation of economic value.

5. Contributing to Solutions

Following the Impact Management Project’s Classifying the effect of an impact, CGM is designed to enable a broad variety of organizations to purchase and supply Impact Assets which Benefit stakeholders and Contribute to solutions beyond simply "Avoiding harm". The marketplace is also expected to serve as a vehicle for fulfilling or exceeding regulatory requirements, supporting sustainability goals, and improving investor-investee relationships.

6. Accessibility

To reduce friction and increase use, acquisition and transaction costs and overbearing process requirements must be minimized. Language used must not be overtly technical so as to preclude non-technical experts from buying, selling and registering assets on CGM. Technology (APIs, calculators, portals, etc.) shall be developed and used to facilitate ease of use and transfer of data.

7. Transparency

The processes, standards, methodologies, data, and impact evidence must be publicly available and accessible to all stakeholders at all times (while still protecting individual’s data rights).

8. Efficiency.

CGM processes, services and standards must be efficient in their application and use to facilitate progress and impact.

9. Objectivity

CGM must be independent, impartial and balanced, and must not favor one stakeholder’s interests or enable unethical gain.

10. Digitization

Quantified, valued and verified impact through CGM must be able to be digitized via serialization or and may be tokenized in order to transparently and securely transfer assets between impact suppliers and impact buyers.
