About · the founder

I've spent my career making technology pay off inside real businesses.

MarginArc is built by an operator and an investor — not a vendor. The whole point is to measure the result like a deal, because that's how I've always measured technology.

01Why me

I'm Matt Rothberg. I have a rare-enough combination for this work: I can build it, I can sell it, and I can underwrite it like a deal.

The technical half: a CS degree and years as a systems engineer at Cisco, shipping complex technology into the world's largest financial institutions. I built and shipped MarginArc's first product — an AI pricing engine — solo. So when I say we'll integrate with your ERP and instrument the result, it's not a slide; I've done the build.

The commercial half: six years selling and engineering technology into demanding enterprises at Cisco and World Wide Technology — including a firm-wide pricing and margin transformation. That project is the origin of MarginArc's whole thesis: prices and processes set on gut feel leave money on the table, and modern AI can finally capture the context that fixes it.

The operator-investor half: a Columbia MBA, and an investor-operator at Montrose Legacy Partners, where I work on lower-middle-market acquisitions — the same owner-operated businesses MarginArc serves. My first company was a B2B IT-services firm that helped businesses modernize their technology. MarginArc is a return to that, with AI.

What it adds up to: I measure technology the way an operator and an investor do — in cash, in labor you can't hire, in payback — not the way a vendor does, in features. That's why we can put our fee on the result.

OPERATE
Founded a B2B IT firm

Helped real businesses modernize their technology. MarginArc is that, with AI.

We have no client logos to show yet — and we won't borrow ones we haven't earned. Until our own audited cases exist, our credibility is the track record above, attributed third-party benchmarks, and a guarantee that puts our fee on the result.

03How we work

Boutique, not a body shop

High-touch, hands-on delivery. You work with the people who do the work — not an account manager and an offshore queue.

Resell the engine, own the case

We don't rebuild what Conexiom and Esker already do well. We own the diagnostic, the financial case, the integration, and the change management.
