Growth puts pressure on software, infrastructure, and teams. The work starts by identifying what is holding the business back, what needs to change, and what should be preserved.

Founded by Dane MacMillan, MacMillan House draws on 18 years of software and web experience across SaaS and competitive e-commerce. Recommendations are informed by experience building systems, leading teams, and managing major technology changes without interrupting operations.

Each engagement is carefully chosen and led by the founder from assessment through delivery. Trusted specialists are brought in when additional expertise is needed.

FAQ

Before getting started.

When should a company bring in MacMillan House?

When technology is making growth harder: systems struggle with demand, costs rise without clear justification, or software delivery becomes slow and unpredictable. An engagement can also help before a major platform investment or when senior technology leadership is needed.

Can MacMillan House assess the health of a technology organisation?

Yes. An assessment examines the technology stack, engineering culture, and software development lifecycle to identify technical debt, unnecessary costs, and delivery bottlenecks. The result is a prioritised plan explaining what needs attention, why it matters, and where to start.

Does improving the technology mean replacing existing systems?

Not necessarily. The first step is to understand what works and where the constraints are. Recommendations may involve improving existing software, changing infrastructure, or strengthening development practices. Replacement is recommended when the benefits justify the cost and disruption.

Can MacMillan House help scale a product built with AI tools?

Yes. The starting point is a review of the product’s architecture, security, reliability, and maintainability. The goal is to preserve what works, address the risks, and establish the engineering practices and technical ownership needed to support growth.
