17 Communications


Our mission is to catalyze the flow of capital towards ESG and impact-oriented investments and solutions through a combination of:





“It is clear that capitalism in its present form has fundamental flaws. It’s not delivering on its promise to share prosperity and to bring social progress for all.”


17 Communications


We pledge to only work with clients whose services or values are aligned with the Ten Principles of the UN Global Compact (UNGC) and/or the 17 Sustainable Development Goals (SDGs).

Alignment on values: We will only work with clients who share our values. By working towards the same goal, we believe we are best positioned to achieve positive outcomes.

Results with transparency: We will be fully transparent about why a communications campaign did or did not work, and provide recommendations about what we can do differently the next time. We believe in learning from failure, not sugar-coating the actual results. 

Impact with integrity: We will not take any shortcuts to get the desired results. True impact requires real effort, and real effort requires time, discipline and skill. There’s no greenwashing or impact-washing here.

“We cannot choose between (economic) growth and sustainability - we must have both.”

SDG 17

Sustainable Development Goal 17 is to “strengthen the means of implementation and revitalize the global partnership for sustainable development.” This idea of global partnership is critical for achieving the SDGs, and is a core part of how 17 Communications conducts business. We believe in the power of many over the power of one and will actively bring in outside partners though the 17C Network as needed for each engagement. We will also evaluate and report on each client engagement through the lens of achieving SDG 17, with a specific focus on the following two indicators:

17.16- Enhance the global partnership for sustainable development, complemented by multi-stakeholder partnerships that mobilize and share knowledge, expertise, technology and financial resources, to support the achievement of the sustainable development goals in all countries, in particular developing countries

17.17- Encourage and promote effective public, public-private and civil society partnerships, building on the experience and resourcing strategies of partnerships

“If you are going to work in finance, then understand the power of finance to actually bring about change in the world. It can be either part of the solution, or part of the problem.”

We are committed to tracking and reporting on the net impact of all business activities. This way each client knows that their fees are being used in an environmentally and socially responsible way.

Goals for 2021: List of specific goals and targets for 2021 such as developing a net-zero plan, diversifying the client base and attaining B Corp certification

2019 Impact Summary

Since 17 Communications was not fully operational until January 2020, we opted not to publish a full Impact Report for 2019. However, in the interests of transparency and intentionality, we put together a ‘2019 Impact Summary’ of what we accomplished in 2019 and as a preview of what’s to come in 2020.

Pro Bono Consulting

17 Communications is available to do pro-bono work for organizations with limited financial resources, particularly non-profits and social enterprises. We have a formal policy to donate the equivalent of at least 5% of our time to pro-bono projects each year. To inquire about a pro-bono engagement, please reach out at [email protected].

Charitable Giving

17 Communications has a formal policy to donate at least 5% of annual revenue to charitable partners each year.

“Yes, we are failing, but there is still time to turn everything around — we can still fix this. I want you to act as if the house was on fire. Because it is.”

Dmitriy Ioselevich, CEO & Founder

Dmitriy founded 17 Communications in January 2020 with a vision to reform capitalism by bringing together the private and public sectors to work towards tackling shared sustainability challenges. This vision was built on a realization that the current socioeconomic system is broken, and that catalyzing the flow of private capital offers the best chance for meeting the scope and scale of today’s problems. As the leader of a mission-driven marketing and communications firm, Dmitriy sits at the center of the conversation around ESG and impact investing, helping different stakeholders communicate with their target audiences and develop a shared understanding of goals, needs and challenges.

Dmitriy was previously the Senior ESG Specialist at Prosek Partners, an independent financial communications agency based in New York. In this role, he oversaw all ESG-related communications activities across Prosek’s roster of financial services clients, which included: asset managers, asset owners, intermediaries, data and research providers, and thinktanks. He also helped manage Prosek’s Content Creation department, with responsibility for writing and editing various pieces of content (e.g., whitepapers, bylines, blog posts, website copy, marketing materials, etc.) across a variety of topics (e.g., ESG, investment management, wealth management, fintech, banking, financial regulations, entrepreneurship, etc.).

Dmitriy started his career at The Deal LLC (now a part of TheStreet.com Inc.), and also held financial communications roles at Brunswick Group, Walek & Associates and Peppercomm. He graduated from Syracuse University with Honors and a B.A. in Public Relations and Economics. Dmitriy is a member of the CFA Society of New York (CFANY) and a small business mentor as part of Pacific Community Ventures’ BusinessAdvising.org platform.

"The imperative of the 21st century is to build a new economy that recognizes the role of business and corporations in creating value in ways that better benefit society.”
