● Knows your home
Is $8,200 fair for a Goodman AC in South Jersey?
That’s within range. 3-ton Goodman systems typically run $6,500–$10,000 installed in your market. Labor is usually $1,800–$2,500 of that. Ask for an itemized quote before agreeing.
How long will it last?
Goodman averages 15–18 years with annual service. You’re in good shape — I’ll remind you when it enters the watch zone around 2034.

The problem we’re solving

The biggest purchase of your life shouldn’t feel like a guessing game.

Buying a home is already one of the most overwhelming things you’ll ever do. Then you close, the inspector leaves, and suddenly you’re responsible for a building full of systems you’ve never managed before — with no guide, no history, and no idea what anything should cost to fix.

Bones exists to change that. Not to add more complexity, but to cut through it — giving you the organized record, the real cost context, and the AI guidance you need to make smarter decisions about the home you worked so hard to buy.

Buying a home
A 40-page report full of findings you couldn’t fully interpret. Then the inspector left and you figured it out as you went.
🔧
Maintaining a home
Contractors quote with no basis for comparison. You have no idea if $8,200 for an AC is fair or $2,000 too high.
📉
Selling a home
Buyers discount for uncertainty. The $40K in improvements you made are invisible without documentation.
With Bones
Every project, system, and dollar is in your Bones Blueprint. Your home tells its own story — and it’s worth more because of it.

Bones Blueprint

The full story of your home.
Written by you.

Every project, receipt, permit, and warranty — logged, organized, and yours forever. When you sell, you can transfer the Blueprint to the next owner — if you choose to. Buyers pay more for homes they understand.

Ask Marrow
● Your home AI
Why did my mortgage payment go up $94 this month? Nobody told me it was changing.
That’s almost certainly an escrow adjustment. Your servicer does this annually — they recalculate what you’ll owe for property taxes and homeowners insurance in the coming year, then adjust your monthly payment to cover it.

Your mortgage payment has four parts: principal, interest, taxes (escrowed), and insurance (escrowed). If your taxes or insurance went up, your escrow payment goes up too — and so does your total monthly payment.
Is there anything I can do about it?
A few things. First, check your annual escrow analysis letter — it shows exactly what changed. If your insurance premium increased, shop your policy. If property taxes went up, you may be able to appeal your assessment. Based on your Bones Ledger, your current insurance is $1,840/yr — want me to flag that for review?

Our approach

Built for homeowners first.
Everything else follows.

Bones is built entirely around one question: what does a homeowner actually need to feel confident about the home they own?

✕ Not a marketplace
✕ No ads. Ever.
✕ No contractor kickbacks
✕ Your data is never sold
✕ No pay-per-lead
“Good bones isn’t something a home has. It’s something you build — one decision at a time.”
01
The homeowner experience comes first
Simple, useful, and genuinely valuable from day one. The Blueprint captures everything. Marrow answers anything. Trust is earned before anything else is asked.
02
Built for the long game
Bones becomes more valuable the longer you use it. A home with three years of documented history is worth more than one with none. The homeowner who builds their Blueprint builds something real.
03
Intelligence that earns its place
Every feature in Bones exists because a real homeowner needed it. Bones Insights, Bones Scan, Bones Benchmark — each one earns its place by making homeowners more confident, not more dependent.
04
Transparency that transfers
The Blueprint you build doesn’t disappear when you sell. It transfers with the home — if you choose to share it. That continuity is what makes Bones different from every other home app.
05
Contractors who earn trust, not pay for placement
No pay-per-lead. No sponsored listings. If a contractor appears in Bones, it’s because homeowners who documented real work said they were worth it.

Community-Built Transparency

The more homeowners document,
the smarter Bones gets for everyone.

The more homeowners document, the more accurate Bones Benchmark becomes for everyone in your market. Real costs from real homeowners — not algorithm estimates, not industry averages.

When you log a project, you help the next homeowner in your neighborhood know what it should actually cost. That’s the kind of transparency homeowners have never had before.

Better data for you.
Better data for your neighbors.

📊
Real project costs
Homeowner-submitted pricing data by project type, market, and contractor — not industry estimates.
📍
Your market, specifically
Cost ranges narrowed to your area as more homeowners in your neighborhood contribute their records.
🔒
Always anonymous
Your personal information is never shared. You control whether your data contributes to community benchmarks.
Always improving
As more homeowners in your area log projects, cost estimates become more accurate and more local.

Why Bones exists

Built by a homeowner who got tired of
being surprised by expensive emergencies.

$8,280
AC replacement — no idea how old it was or what fair looked like
$10,530
Water seeping into the garage — cracked kitchen drain had been leaking under the foundation silently, for who knows how long
$5,623
Electrical panel that couldn’t support the house — 100A upgraded to 200A with whole home surge protection
$3,749
Front entry steps — removed 4 layers of brick and concrete, repoured from scratch
Spent since moving in
$60,000+
The kitchen drain repair was partially covered by insurance — after months of calls, adjusters, and contractors. Everything else came out of pocket.
Every dollar and every hour came out of time that could have been spent on something more important.

The drain repair was the one that hit hardest — not because of the cost, but because of the timing. It started with water mysteriously seeping into the garage. No obvious source. Eventually a plumber traced it back to a cracked kitchen drain pipe running under the foundation — silently draining water into the ground for who knows how long. The kitchen was gutted. Concrete was jackhammered up. Dust settled into every corner of the house. And those were the exact months we brought our daughter home for the first time.

“It wasn’t necessarily anyone’s fault. It could have been wear and tear, a bad install by a licensed contractor, or a confident DIYer who didn’t know what they didn’t know. There was just no way to tell. That’s the problem.”

The AC was the first hit. One year after moving in, in the middle of a hot New Jersey summer, it died. A salesman came out and told us it would be $8,280 to replace. We were hot, stressed, and had no context for whether that was fair. We said yes.

When we mentioned the cost, the salesman said something that stuck: “This is just part of homeownership. The last owners replaced the roof — you’re replacing the HVAC.” Like it was inevitable. Like we should just accept it and move on.

We didn’t know if $8,280 was fair. We didn’t get a second bid. It was summer, the house was hot, and we had no idea what a Goodman 14 SEER unit should cost in South Jersey. We made the only decision we felt we could make in that moment — and we’ve wondered ever since if we overpaid.

That mindset — “this is just part of homeownership” — is exactly what Bones is built to replace. Not with the promise that nothing will break. Things break. Systems age. Surprises happen. But there is a meaningful difference between a homeowner who gets a surprise bill and has no context, and one who already knows what it should cost, knows what questions to ask, and knows what a fair quote looks like before anyone walks through the door.

What became clear through all of it is that homeownership rewards the prepared. The homeowner who documents everything, pulls permits, keeps receipts, and maintains what they own — that home tells its story clearly. The homeowner who doesn’t — for whatever reason — passes that uncertainty on to the next person. And that next person has no way to know the difference until something breaks.

Bones exists because no homeowner should go through this blind. Not the buyer who deserves to know what they’re actually purchasing. Not the owner who wants to stay ahead of what’s coming. Not the seller who did everything right and can’t prove it. And not the parent who just wants to spend their weekends with their kid — not on the phone with their insurance company.

We hope our story inspires other homeowners to document, protect, and take pride in the homes they care for — and helps the next generation of buyers know what they’re really getting into.

And then there was the furnace. A freezing night — our daughter was a newborn — and the furnace stopped staying on. We called to get someone out, couldn’t get anyone quickly, so we reached out to another company who came the next day. That night, the house was cold. We had a newborn. We were panicked.

Come to find out — a vent was blocked. That was it. A blocked vent. Something any knowledgeable friend could have walked us through in five minutes over the phone. That’s exactly what Marrow is. Not a replacement for a technician when something is genuinely broken — but the helpful, knowledgeable guide who asks the right questions first. “Have you checked your vents? Is the filter clean? Is the thermostat set to heat?” The kind of questions that turn a panicked night into a problem solved.

Every feature in Bones was built around a simple question: would this have helped us before we bought our home, or after? If the answer was yes — we built it. Not because it seemed like a good idea, but because we lived the version of homeownership that didn’t have it.

Good bones isn’t something a home has. It’s something you build — one decision at a time.
