Our Services
Grants - Retainer Services
Grant deadlines don’t wait for your team to catch its breath. With a monthly retainer, you get a dedicated grant partner who researches funders, writes and polishes proposals, and keeps your calendar on track all year. Choose the level of support that fits your organization, from essential coverage to full-service partnership. You get steady, strategic funding work without the cost of a full-time hire. Your mission stays at the center while we keep the dollars moving toward it.
What you can expect:

Grants - Project Based Services
Sometimes you don’t need a full retainer, you need the right help at the right moment. Whether you’re staring down a deadline, picking up the pieces after a decline, or building a funding plan for the year ahead, our project-based services are scoped, priced, and focused on a clear result. Get a pre-submission review before you apply, a funder list and 12-month calendar, a master case for support, or hands-on training for your team. Every project leaves you with something concrete you can use right away.
Fundraising Assessment & Organizational Services
Before you can raise more, you need to know what’s working and what’s holding you back. We take an honest look at your fundraising systems, then help you build the structure, strategy, and calendar to grow with confidence. From a full assessment to major gifts, donor retention, and feasibility studies, each service is designed to make your development efforts more sustainable. The result is a fundraising program that doesn’t depend on any one person, grant, or season.
Private Foundation & Corporate Philanthropist Services
Funders want to make a difference, but their own processes can get in the way. We help foundations and public funders design applications, guidelines, and reporting that are simpler, fairer, and centered on the community. Our work includes application redesign, equity reviews, listening studies, and grantee cohorts that help funded organizations grow. When your process is easier to navigate, you hear from more of the organizations you most want to reach, and your dollars go further.
Board/Leadership Fundraising Training
Strong fundraising starts at the top, but most board members were never taught how to do it. Our retreats turn hesitation into confidence by giving your leaders clear, practical language and simple steps they can take the very next day. Choose a half-day retreat for a focused tune-up or a full-day retreat for a deeper dive, each tailored to your organization. Your board and leadership team walk away understanding their role and ready to act on it.
Keynote Speaking Engagements
The right speaker can change how a room thinks about giving. Whether you’re hosting a conference, a gala, or a leadership summit, a keynote brings practical fundraising insight in language your audience can follow and remember. Attendees leave energized, with fresh ideas and a clearer view of how they can help advance the mission. Every talk is shaped around your event’s theme and audience, so it feels like it was written just for your room.
