Rebuilding Construction Finance: Why We Invested in Truss

We are excited to announce that Truss has raised $5M in seed funding led by Bonfire Ventures, with participation from Crosslink Capital, Y Combinator, and others.

Construction Runs on Cash Flow. So Why Does It Have the Slowest Money in the Economy?

In any business, cash flow is king. In construction, it's survival — and the industry is uniquely bad at it. Construction moves more money than almost any sector in America, yet it moves that money slower than almost any other. It's a $2 trillion industry running on financial plumbing built for a different century.

The reasons compound on each other:

• The dollars are enormous, and they move at the worst possible times. Contractors and suppliers front huge sums at the start of a project, long before they're paid for it.
• Every project is a crowd. A single job threads a general contractor, a stack of subcontractors, and a web of suppliers — each with their own terms, timing, and leverage.
• The cadence is relentless. Payments hit monthly, or per milestone, or whenever the next draw clears.
• Everyone wants to be paid differently. In-demand subs dictate how they get paid — and in construction, that still often means a physical check.

The tools built to handle all this are badly outmatched. Legacy banks are slow and painful to use. Horizontal fintechs treat construction as an afterthought — a black box that ignores the industry's real-world habits, checks included. The result is an industry where late payments are the norm, not the exception, and where cash-flow gaps quietly kill otherwise healthy businesses.

Truss Flips the Script

Truss is banking built for the way construction actually works:

• Money in, fast. Contractors collect payments and get access to funds quickly — closing the gap between "client paid" and "I can make payroll."
• Money out, effortless. Pay subs and vendors in minutes, through whatever channel that sub actually wants, including checks.
• The whole stack, unified. Business checking, bill pay, receivables, crew cards, and physical checkbooks — one platform instead of five vendors and a shoebox.
• No BS on fees. Built to reward the businesses doing the work, not to nickel-and-dime them.

How Truss Makes Money and Why the Model Is the Moat

A typical payment processor sits in the middle of a transaction, taking a single fee as money passes through, then handing it along. It owns a slice of the flow — nothing more.

Truss owns the whole thing. Rather than skimming one fee, Truss becomes the account a construction business actually runs on — where money lands, sits, gets spent, and gets paid out. That means a single customer generates revenue across their entire financial footprint, not one transaction: payments coming in, card and spend activity, money going out to subs and vendors, the instant-payout speed contractors happily pay for, and the deposits sitting in the account between projects.

Same construction software on top — but Truss captures the whole wallet underneath, not a sliver of it. And because the economics are spread across fee- and account-based revenue, the model gets stronger and more durable as customers run more of their financial life on Truss, instead of depending on squeezing any single payment.

Every Payment Recruits the Next Customer

Here's the part that compounds. Because Truss is the account a business runs on, a contractor doesn't just bank on Truss — they pay their subs and vendors on it. Those subs sign up to get paid, then turn around and pay their network on Truss. And so on down the chain.

Acquisition becomes a byproduct of usage. Every payout is effectively an invitation, so the network grows itself — and the cost of landing the next customer falls as the graph gets denser. This is the rare flywheel where the product's core function and its growth engine are the same motion: using Truss is distributing Truss.

That closed-loop dynamic, inside a tight-knit and referral-driven industry, is a genuinely durable advantage. In construction, everyone eventually transacts with everyone — and the more of that web that runs on Truss, the harder it is for anyone in it to leave.

Why This Compounds Into a Moat

Any fintech can put a slicker interface on top of a bank. What's hard — and what Truss actually built — is owning the layer underneath:

• The operating account, not a point tool. Truss owns the account, the ledger, and the customer relationship — the parts that make it the system of record, not a feature bolted onto someone else's platform.
• A payments graph specific to the trades. Because contractors pay subs, and subs pay vendors, every transaction maps another node in a proprietary picture of who-pays-whom in construction — one a horizontal neobank, seeing only one side of the relationship, can't replicate.
• The switching cost of being the operating account. Once Truss is where a business banks, spends, and settles, it's not a tool you swap out — it's the account everything else routes through. That's the stickiest position in fintech.

The result is a business that gets more defensible as it grows: more accounts feed the network, the network lowers the cost of the next customer, and being the operating account makes each one harder to lose. A processor skimming a single fee has none of these compounding advantages.

The Founder

What grabbed us was the quiet confidence of Truss's founder and CEO, Matthew. He's exactly the kind of founder Bonfire looks for: sharp, articulate, technical, genuinely obsessed with his customer, and ambitious about where this goes. He isn't building a slicker bank. He's rebuilding how an entire industry moves money.

Why We Invested

Construction is one of the largest, most essential, and most financially underserved industries in the country. Truss is attacking its most painful, most universal problem — the speed of money — with a product built by people who understand the job, a revenue model that captures the whole wallet, and a network that grows itself with every payment.

We believe Truss can become the financial backbone of the trades, and we're thrilled to back Matthew and the team on the build.

If you're trying to modernize payments in your construction business, Matthew and the team would love to show you what Truss can do.
