Natasha Miller, an honoree on the Inc. 5000 list of America's fastest-growing private companies, has said she spent years underestimating the importance of company culture before discovering that a deliberate focus on people and core values made her business stronger and better positioned to expand.
Miller's assessment, delivered in a video interview, amounts to a straightforward argument for British founders and managers navigating a tight labour market and persistent pressure on margins: the way a company treats its staff is not a soft extra to be addressed once growth allows, but a foundation on which growth depends. Her admission that she overlooked culture for years gives the point added weight, since it comes from an operator who has already built a business of sufficient scale to be recognised among the United States' fastest-growing private enterprises.
The claim rests on three connected elements — people, core values and culture — which Miller treats as a single system rather than separate initiatives. Investing in employees, she suggests, is what allows an organisation to hold on to the values it claims to stand for, and those values in turn shape how decisions are made as a company grows. The result, in her account, was a stronger business with a firmer platform for expansion.
For UK readers, the observation lands in a difficult operating environment. Small and medium-sized enterprises have spent recent years absorbing higher employment costs, elevated borrowing rates and uneven consumer demand, all of which make spending on staff development and internal culture feel like a discretionary luxury. Miller's experience points in the opposite direction: that such spending is what protects a company's ability to grow when conditions are unforgiving.
Culture has also become a live issue in British corporate governance. Regulators and investors increasingly expect boards to account for workforce treatment, retention and conduct, not merely financial performance. Companies seeking capital or preparing for a sale are routinely asked to demonstrate that their values are embedded in practice rather than displayed on a website. Miller's argument that culture starts with how people are treated speaks directly to that expectation, because it locates the substance of culture in everyday management behaviour rather than in formal statements.
Her framing also carries a warning for founders who defer the question. A business that scales quickly without attention to how employees are treated can find that growth exposes weaknesses rather than curing them — through higher turnover, inconsistent decision-making and a workforce that does not share the company's stated priorities. By contrast, an organisation that invests early in people and values builds the internal coherence that makes expansion less disruptive.
None of this is presented as a guarantee. Miller's account is a personal one, drawn from her own company's trajectory, and it does not claim that culture alone determines commercial outcomes. But it does challenge the common assumption that attention to people is something a business can afford only after it has succeeded. In her experience, the sequence ran the other way: the investment in people and values came first, and the stronger, more growth-ready company followed.
For British managers weighing where to direct limited resources, the practical implication is modest but clear. Treating employees well, defining core values and then applying them consistently is not a distraction from building a company. On Miller's evidence, it is part of how a company becomes worth building in the first place.
