Nonprofit Growth Advisory from PR Bunker

The Mission Engine

Most nonprofits don't have a marketing problem. They have an infrastructure problem. The story is there. The impact is real. What's missing is the machine that turns that story into donors, press, and growth, month after month. The Mission Engine installs that machine.

See the three tiersBook a call with Don

A thought partner for executive directors

Work 1:1 with Don Martelli, a former Boston Globe reporter who has spent 25 years building communications engines for organizations from startups to global brands. This is not a course. It's not a mastermind. It's an operator in your corner, building your growth infrastructure with you.

Donor asks that land

Structure the ask, the audience, and the moment. Major gifts, annual appeals, and the executive channel that most nonprofits never build.

Drip campaigns & sequences

Donor journeys, lapsed-donor win-backs, and stewardship sequences your team can run on the tools you already own.

Talking points & messaging

Board decks, funder meetings, press moments. Say the right thing, the same way, everywhere it counts.

AI-powered infrastructure

AIOS agents built for your organization: donor follow-up, story pipeline, grant tracking. Systems your team runs in your own tools.

One Boston Globe story, placed the right way, raised $250,000 for a nonprofit client. No direct ask.

That's what storytelling as a revenue driver looks like. The Mission Engine installs that playbook inside your organization.

Three ways in

Start where the budget allows. Scale when the engine proves itself. Every tier is 1:1 with Don. Annual prepay available on every tier at 10% off.

Frequently asked questions

What is nonprofit growth advisory?

Nonprofit growth advisory is 1:1 strategic guidance for nonprofit leaders on the systems that drive revenue: donor relations, fundraising campaigns, storytelling, earned media, and marketing infrastructure. Unlike an agency retainer, you're not paying someone to do the work for you. You're building the capability inside your organization, with an experienced operator guiding every decision.

How is the Mission Engine different from hiring a PR agency?

An agency does the work for you and charges accordingly. The Mission Engine teaches you to build the machine yourself, at a fraction of the cost. PR Bunker's agency clients invest $5,000+ per month for done-for-you work. Mission Engine members get the same playbook, the same judgment, and the same methodology, applied through advisory sessions and systems your team runs. If you outgrow it and want the agency, that door is open.

What is an AIOS agent?

AIOS agents are AI-powered systems designed for your organization: a donor follow-up engine, a story pipeline that feeds your newsletter and press outreach, a grant deadline tracker. Don architects each agent as a blueprint; your team runs it in your own tools. No new software subscriptions, no dependency on us.

We're a small nonprofit with no marketing staff. Is this for us?

That's exactly who Cadence was built for. Most Mission Engine members are executive directors wearing five hats with no dedicated marketing hire. The point of the program is to give you infrastructure that works without one, at a price a board approves without a fight.

What's the commitment?

Cadence and Operator are month-to-month. Cancel anytime. Architect carries a six-month minimum because we're building your full six-agent infrastructure stack and doing it right takes six months. Annual prepay saves 10% on any tier.
