Grant Miller

Grant Miller runs one of the least glamorous corners of software, and he likes it that way. As co-founder and CEO of Replicated, he spends his days on a problem most consumer tech never touches: how do you hand a piece of software to a bank, a hospital, or a government agency and let them run it entirely inside their own walls, where no data ever leaves the building?

That question sits under everything Replicated builds. The company gives software vendors a way to ship their applications so customers can install and run private instances in their own secure, self-managed environments - on-prem, in a private cloud, or fully air-gapped. It is the kind of work that rarely makes headlines and almost always makes payroll for the customers who depend on it. Finance, government, and healthcare cannot simply pipe their most sensitive data into someone else's cloud. Replicated is built for exactly those buyers.

Miller founded the company in 2015 and has since raised more than $80 million to chase it, including a $50 million Series C in July 2021. Along the way he turned a phrase that once drew laughter into a real category. "Some Salesforce exec laughed in my face when I told them that we were going to make on-prem software cool again," he has recalled. The bet was that the industry's rush toward pure SaaS had left a large, permanent set of customers behind - and that serving them well was a business worth building.

His definition of "modern on-prem" is deliberately unromantic. It is not about nostalgia for shipping CDs. It is about giving large organizations the same convenience as SaaS - updates, monitoring, license management, access controls - while keeping the software running somewhere the customer fully controls. Replicated leans on Kubernetes, Helm, and a stack of distribution tooling to make that possible, and increasingly on supply-chain security: scanning releases, telling customers which versions are running, and flagging whether those versions carry known vulnerabilities.

A nine-month exit, then a longer game

Miller did not start in infrastructure. His first job in technology was in the deal room: investment banking at Goldman Sachs, working on technology mergers and acquisitions. It was a front-row seat to how software companies get valued and sold, but not to how they get built.

The building came next. His first company, Look.io, was a plugin that let mobile apps and websites drop in live customer-support chat. It started as a startup-weekend project, raised roughly $200,000 in advisory funding, and landed HotelTonight as an early customer. Then a cold call arrived from LivePerson's head of mobile. About nine months after it began, Look.io was acquired.

A fast, clean exit is the outcome most founders chase. Miller took a different lesson from it. He came out of the sale wanting to build something with a much longer horizon - a company he says he never wants to sell. That ambition became Replicated.

He taught himself to code to earn a co-founder

One detail explains a lot about how Miller works. Early on, he could not find a technical co-founder, so he taught himself to program through Harvard's free computer science coursework. He is also credited with a computer science background from Stanford. The point of the self-teaching was not to write the whole product himself. It was to be able to evaluate technical decisions and to earn the respect of the engineer he wanted to build with - his co-founder Mark Campbell. The partnership that followed set the foundation for what came next.

That instinct - go learn the thing well enough to have a real opinion - runs through his public work too. In 2018 he launched EnterpriseReady, both a resource site and a podcast, built around a simple reframing: most of the conversation about enterprise software is about how to sell to the enterprise, when the harder and more useful question is how to build for it. On the show he interviews enterprise software leaders about the features that actually drive adoption, from audit logs to single sign-on, and why so many of them get shipped as checkbox exercises rather than tools people want to use.

The path so far

Building for the customers who can't compromise

Where the industry has spent a decade optimizing for the smooth demo and the frictionless signup, Miller has spent it optimizing for the opposite: the customer who cannot send a single byte outside the firewall. That constraint is not a niche. It is the operating reality of regulated industries, and it is not going away.

Replicated's newer work pushes deeper into that reality. The company has leaned into supply-chain security and visibility - helping vendors see which of their releases are running in the field and whether they carry vulnerabilities, and helping customers trust the images they deploy. It is a natural extension of the original idea. If you are going to let software run in places you cannot see, you had better give everyone involved a clear picture of what is actually there.

Miller also keeps a foot in the investor world. He spent years as a partner at First Round Capital and, in 2023, joined Bee Partners to back early-stage enterprise software and AI companies. It gives him two vantage points on the same market: one from inside a company that ships to the enterprise every day, and one from across the table, watching the next wave of founders try to do the same. For someone whose throughline has always been enterprise software, that double life is less a distraction than a research program.
