Build or Buy: What Should Your Business Own in 2027?

AI makes building more possible. It doesn't make building everything a good idea.

The strategic advantage comes from knowing the difference between software that is simply infrastructure for your business and software that increasingly defines your business.

Capabilities that once required large teams, long timelines and significant maintenance can increasingly be built and operated differently. That reopens the build vs. buy software decision for business and technology leaders: which parts of your stack should remain rented, and which are important enough to your differentiation, economics or customer experience that you should own them?

Some capabilities are still clearly better bought. Specialized commodity software can carry operational, reputational or technical risks that make building it yourself a poor decision. Others are part of what makes your business different, and may be worth owning.

The economics of software development are changing. Businesses now have more options than accepting the limitations of SaaS or funding a massive custom software project. AI-assisted development makes certain forms of ownership significantly more viable, and modern infrastructure approaches give companies greater control over their applications, data and deployment. That doesn't make building the default answer. The question becomes what to buy, what to build, what to own, and where dependency has become a strategic constraint.

Nick Van Weerdenburg and Ben Hofferber will break down a practical framework for making that decision in 2027.

Each layer runs on the one beneath it.

What you'll learn

  • How AI-assisted development changes the build-versus-buy math
  • How to tell differentiating capabilities from commodity ones
  • When a vendor's expertise and scale still make buying the smarter call
  • How to weigh dependency, switching costs, customer experience and control
  • How to make ownership a deliberate part of your 2027 technology strategy

This session is for you if…

  • You're making architecture or platform decisions for 2027.
  • You're evaluating new SaaS purchases or existing vendor dependencies.
  • You're wondering whether AI makes previously unrealistic internal builds feasible.
  • You need a practical way to decide what your organization should own versus continue buying.
