Feeling lost in the social impact wilderness?

We partner with social impact organizations to strengthen the internal alignment, capacity, and strategy needed to generate consistent, growing revenue.


You’re solving the world’s problems. Who’s solving yours?

Your Social Impact Organization needs more money. You feel like it’s the root of the issue and if you could just have more, you could hire that person, build that program, and solve that need. Instead, you’re denied for grants, your donors are fatigued, and you don’t know how to access new funders.

You know you need help but you can’t quite figure out the problem. You’ve tried hiring one-off experts to solve one-off issues but something still isn’t right. You’re missing opportunities and deadlines. Your board is pushing for progress yet they don’t even really understand what you do.

Where do you focus first? Raising money? Fixing unidentifiable issues?

What you really need is a committed, trustworthy, neutral 3rd party to help you decipher what’s holding you back and design a prioritized trail map to reach your full potential — and ultimately achieve your mission.

We focus on what actually drives revenue, developed over 20 years of on-the-ground experience.

Clarity of Purpose
Your mission, vision, and story are clearly defined and compelling to funders.

Aligned People
Staff, board, and leadership understand their roles in fundraising—and are equipped to fulfill them.

Strong Processes
You have the systems and infrastructure needed to support consistent, effective fundraising.

Right Prospects
Your funding strategy is built around the right mix of donors and partners, with a clear path to engagement.

Who We Are

Osa Philanthropy believes that each social impact organization has a unique contribution to make to this world. We help you unlock your unique lifeforce through a 360° partnership designed for social impact organizations.

Founded by Lara Sepanski Pimentel, a mother, and humanitarian who discovered her need to do well by doing good as a Peace Corps Volunteer in the Dominican Republic. That experience, along with a Master of Public Administration degree from Syracuse University, and about 20 years of work, has shaped Lara’s understanding of the world. This is her unique contribution, and through it, she has impacted nonprofits and their beneficiaries with sharp fundraising expertise. Lara has raised more than $23M throughout her career from individuals, foundations, corporate partners, sponsors and small government grants.


Who we partner with:

Osa Philanthropy partners with nonprofits and mission-driven businesses united by a commitment to positive social impact. While we appreciate the varied challenges for-profits face, we remain laser focused on their Corporate Social Responsibility, social enterprise, nonprofit arm, embedded social purpose, or social impact initiative. We work with every sector, geography and size.

Don’t wander through the wilderness alone.
