I had a debate with an entrepreneur this past weekend about AI and software companies. The question was whether AI will disrupt mission-critical software companies. Think ERP, CRM, and HCM software like NetSuite, HubSpot, Salesforce, Workday, etc.

Having built an ERP system with CRM functionality, my answer is no. In the short to medium term, these software companies will continue to have a strong moat. I believe this for two reasons. First, these systems are very complex and run functions that are mission critical. The risk of replacing one of them with a system that doesn’t work as well is too high, even if the upside is saving money. Disrupted operations can lead to significant financial losses and tarnish a company’s brand. Most companies don’t want to take those kinds of risks (start-ups might, though).

When I was running my company, there was zero chance you could get me to change from the ERP/CRM system we built for ourselves. The risk and learning curve associated with switching were too high. Even if someone had given me the software for free, I would have said “no thanks.”

Cost is the second reason I believe mission-critical companies aren’t about to be disrupted by AI. Having AI build a system as complex as the ones mentioned above would take significant time and energy and cost a ton via tokens. Then there’s maintenance. You can’t just build it and forget about it; you have to maintain homegrown systems, which can require material resources. When a company thinks about the time, energy, and cost required to build and replace a system, they’ll keep what they have and allocate those resources to high-return activities.

My company’s internal software was a living thing. We were always making improvements and changes to it. I learned over the years to budget a certain amount of salary and team bandwidth for maintenance of this software.

Complex, mission-critical software is the backbone of many companies. If one of these systems stops working, a company is flying blind and in some cases can’t operate at all.

As of today, I don’t think these companies are at risk of losing customers. Whether they’ll continue to grow at historical rates is a legitimate question. I think the probability that they will is high, because I doubt that company leaders want to start building these types of systems from scratch. The return on the allocation of resources doesn’t make sense.
