Our Values

These aren’t aspirational posters on a wall. They’re the daily practices that shape how we build, who we serve, and why we say no more often than yes.

We care more than makes sense on paper. That’s not a tagline. It’s a daily practice. It looks like sending a handwritten note after a kickoff call. Flying in for a meeting when a video call would’ve been fine. Losing sleep over your architecture because we know how much is riding on it. We believe the best work happens when someone is emotionally invested in the outcome, not just contractually obligated to deliver it.

Our Story

The Heartwood Story

We named Heartwood on a road trip. My wife and I were driving home from a family vacation, tossing around names for hours, and when “Heartwood” came up, it resonated immediately. It captured everything I wanted this company to be.

The heart is about how we care. One of our original taglines was “we care more than makes sense on paper” — and that’s still true. The heart in Heartwood represents choosing projects that demonstrate real care for people and the world around us. Not care as a marketing strategy. Care as a conviction.

Then there’s the wood. Heartwood is the hardest part of a tree — the dense inner core that endures through storms, weathering, and time. When everything else breaks down, the heartwood is what lasts. Over years of building software at places like YouVersion and Planning Center, I learned that software has to be that way too. It can’t be brittle or fragile. It needs to be meaningful in its impact, but also stable, secure, and built for longevity. Software that’s still standing years from now, not just useful in the moment.

That combination — deep care and enduring craft — is what we’re building toward every day.


The long road here

I didn’t plan to start an agency. For 25 years, I built software. I wrote code for energy startups and defense contractors. I helped build Bible.com into a platform serving millions of daily users. I led engineering teams at YouVersion — overseeing search, personalization, and content partnerships for a Bible app with over 500 million downloads. I managed a $12 billion annual donation platform at Planning Center, leading teams that handled fraud detection and trust at scale.

Along the way, I spent 13 years as a youth pastor. That season shaped me more than any engineering role. It taught me to listen before I solve, to care about the person in front of me more than the problem on the screen, and to lead with patience even when the pressure says otherwise.

When my role at Planning Center ended unexpectedly, I faced a choice. I could chase another corporate job. Or I could take 25 years of experience — the technical skill, the leadership instinct, the pastoral care — and invest it in something I’d been quietly dreaming about for a long time.

I chose the dream. And doors started opening.

Friends referred work. Generous leaders entrusted me with high-stakes projects during a deeply uncertain season. I hired people from my network who were between opportunities — talented developers who needed a chance and were willing to bet on something new alongside me.

Heartwood wasn’t born from a polished business plan. It was born from calling. From the conviction that there are ideas sitting in notebooks and pitch decks all over the world — meaningful ideas that never get built because the person carrying them doesn’t have the team, the expertise, or someone who believes in the mission as much as they do.

We exist to be that someone.

We were built to count, as water is made to run downhill. We are placed in a specific context to count in ways no one else does. That is our destiny.
Dallas Willard
Dallas WillardAuthor, The Divine Conspiracy

We believe that. We believe every meaningful idea, every impulse to lift someone up, every mission that keeps a founder awake at night comes from somewhere deeper than ambition. You don’t have to share our faith to share our table. If the work you’re doing is good, we want to be part of it.


A different kind of agency

For years, I was on the other side of the agency model. I hired agencies, and honestly, I didn’t trust most of them. The relationship felt transactional: you pay them, they build the thing, and then they disappear. They never really understood our culture or our mission.

Stepping into Heartwood as an agency felt strange at first — until I realized I didn’t have to repeat that model. I could build something where we’re just as invested in your idea as you are. Where every project is a partnership, not a transaction. Where we say no to most opportunities so we can say a deep, committed yes to the right ones.

Better one handful with peace than two handfuls with toil and chasing after the wind.
Ecclesiastes 4:6The Bible (NIV)

We don’t chase the wind. We choose carefully. We invest deeply. And we build things that last.

What you do in the present — by painting, preaching, singing, sewing, praying, teaching, building hospitals, digging wells, campaigning for justice, writing poems, caring for the needy, loving your neighbor as yourself — will last into God’s future.
N.T. Wright
N.T. WrightAuthor, Surprised by Hope

We build software with that conviction. Not just for the launch. For what lasts.

Our Kind of People

We work with mission-driven leaders — founders, directors, managers, technical leads — who carry work they deeply believe in. Their title matters far less than their posture. What unites them is this: they’re working to set some corner of the world right.

They believe their mission matters. They steward resources carefully. They want a partner who takes their work as seriously as they do — not a code factory that builds blindly and moves on. They may come from wildly different contexts: a nonprofit director stewarding donor dollars, a startup founder with an idea that keeps her up at night, a middle manager inside a massive system who sees a crack that nobody else is fixing, a church leader who knows technology could serve their congregation better but doesn’t know where to start.

What they share is a posture we call humble swagger. Swagger because they know their mission matters. Humility because they admit they don’t know everything. And courage because they’re willing to test assumptions instead of protecting them.

If that sounds like you — whether you’ve built a dozen products or you’ve never built an app in your life — you might be carrying an idea that deserves to exist in the world. We’d love to hear your story.

Michael Martin

You don’t have to carry it alone.

Maybe your idea has been sitting in a notebook for months. Maybe it keeps getting pushed aside because other priorities keep winning. Maybe you’ve tried to build it and it didn’t go anywhere. Not because the idea was wrong, but because you didn’t have the right people around you.

Whatever the reason, the pull you feel toward this work is real. It’s not going away. And you weren’t meant to carry it alone.

We’d love to hear about it. Send us a message and we’ll take it from there. Maybe that’s a video call. Maybe it’s coffee. Maybe it’s just a few emails back and forth. No pressure. No agenda. Just a real conversation about what you’re carrying and whether we can help you bring it into the world.

Let’s start a conversation.
