We build the systems that
power high-performing nonprofits .
Our Approach
We don't do all things. We do the work that matters most.
Aries Consulting is a strategic advisory firm that partners with nonprofit leaders to design the governance, leadership, fundraising, and operational systems that allow organizations to stop managing chaos and start executing strategy.
Every engagement is built on one principle: strong organizations are systems — and every system must work together.
Services
-
Senior leadership deployed strategically — not as a stopgap, but as a catalyst for organizational transformation.
Outcomes:
Stable, decisive executive function during transition, growth, or leadership gaps
Board and staff aligned around a clear direction and operating model
Organization exits the engagement stronger, more structured, and ready for its next leader
Fractional leadership is most effective when it's integrated — not isolated. We use every executive engagement to assess and strengthen the governance, operational, and development systems underneath the leadership layer.
-
We don't build plans that sit on shelves — we design the strategic architecture organizations need to grow with intention.
Outcomes:
A strategic plan that connects mission to financial sustainability, not just programs and aspirations
Organizational design that clarifies structure, decision-making authority, and cross-functional accountability
A multi-year roadmap that is phased, measurable, and sequenced for real-world execution
Strategy is the starting point, not the solution. Every planning engagement is designed to surface the structural, operational, and governance gaps that would otherwise prevent execution — and to sequence the work that closes them.
-
A high-functioning board isn't recruited — it's designed.
Outcomes:
Board structure, committees, and policies aligned to the organization's stage and complexity
Directors who understand their role, engage meaningfully, and govern with clarity
Governance infrastructure that supports — rather than slows — executive leadership
Governance doesn't operate in isolation. We design board structures that are explicitly connected to financial oversight, executive accountability, and long-term organizational sustainability.
-
Fundraising is not a department. It's a system — and most nonprofits haven't built one.
Outcomes:
A diversified revenue strategy that reduces dependence on any single funding stream
Development infrastructure: the pipeline, the relationships, the processes, and the tools
A fundraising function that is strategic, staffed appropriately, and integrated with programs and communications
Development strategy is only as strong as the organizational systems around it. We connect fundraising to governance, financial planning, and programmatic impact — so the case for support is built into how the organization operates, not just how it communicates.
-
Most nonprofits are held back not by lack of vision — but by the absence of the systems needed to execute it.
Outcomes:
A clear operational model that defines how the organization functions, makes decisions, and allocates resources
Systems and infrastructure — technology, workflows, staffing structures, and processes — aligned to strategic priorities
An organization that runs with clarity and consistency, not just the effort and instinct of its people
This is the connective tissue of everything Aries does. Governance, leadership, fundraising, and strategy all depend on a functional operational core. We design systems that integrate across every function — so the organization moves as a whole, not as a collection of disconnected parts.

Meet the Founder
Anna Assenmacher, Founder + Principal
I work with mission-driven organizations to build the systems that power high-performing nonprofits.
As the founder of Aries Consulting, I partner with boards and executive leaders during periods of transition, growth, and organizational complexity — helping organizations stabilize operations, strengthen governance, and design the structural infrastructure required to scale impact. I often describe my role as a systems architect for social impact: translating vision into durable structures that support strong decision-making, healthy teams, and long-term sustainability.
My work draws on 15+ years as an executive director, board president, and strategic advisor — and extends beyond consulting into community building. I am the founder of the North Shore Network, an executive leadership community for women leaders, and the Impact Network, a peer-learning platform for nonprofit executives across the region.
