Agustín Guerra is the CEO and Co-Founder of Vangwe, a Consulting and Software Development company specialized in Fintech and Payments.gettyI get asked a version of the same question in almost every client conversation lately. If AI can build the product, why would I hire a software partner?My answer has not changed in two years, but the evidence keeps piling up.The truth is that building software has never been faster or more efficient. A competent team with modern tooling can now ship in weeks what used to take months. But speed changed the game in a way many people misread, and the product still matters enormously.What stopped mattering as much as before is the ability to produce code quickly, because anyone can have that now. The question buyers ask now shifts from "Can you build it?" to "Do you understand my industry well enough to build it right?"That question is answered by four things, and in my experience running a fintech consulting and engineering firm across Europe, the U.S. and Latin America, they now decide who wins.​AI writes code, but teams are the ones who earn trust.One of the most important decision-makers for a buyer in this industry is the team. Enterprise clients take special interest in knowing who’s going to show up when things get complicated. For instance, who’s going to pick up the phone when settlement breaks at 2 a.m., who has previous experience solving this type of chargeback pattern before and who is still going to be around in the next three years.It is true that AI can generate an integration, but it cannot go deeper into thought on things that revolve around that execution. For example, it cannot tell you which of 30 payment gateways will fail you on refunds in a specific market, because it does not have the experience nor the fundamental knowledge to do so.The engineer who has lived through those integrations carries knowledge that no model produces, and clients feel the difference in the first meeting. In this era, who builds your product becomes a part of the product.​Reputation is one of the top competitive advantages.Trust is built slowly. It is built deal by deal, delivery by delivery, and it transfers through networks. Most of our best engagements did not come from outbound; they came from someone who worked with us telling someone else.In a market flooded with AI-generated pitches, decks and demos, a warm reference from a person your buyer already believes is worth more than any funnel. And here is the part that gets missed: Deep industry expertise is itself a trust signal.When a team knows the regulatory edge cases, the acquirer problems and the fraud patterns of a specific vertical, that knowledge acts as a seal of quality on everything they ship. While speed gets you to market, expertise is what makes the market believe you.​Regulation rewards credibility.There is no way around regulation, and pretending otherwise is expensive. Europe just gave the industry a live demonstration. When the MiCA transition period closed on July 1, only a small minority of the more than 1,200 firms operating under previous national registrations had secured authorization, and even Binance, the largest exchange in the world by volume, suspended regulated EU services after withdrawing its license application in Greece.This means that licensed firms such as Coinbase, Kraken and Crypto.com can now passport their services across all 27 EU member states​ while competing in a market with significantly fewer authorized rivals. The lesson extends well beyond crypto. Regulators do not evaluate your feature list; they evaluate your governance, your ownership and your history. A license is trust made formal, and it takes years to earn it.​Loyalty is still the hardest thing to replicate.Retention was always cheaper than acquisition, but AI has widened the gap. When your competitor can clone your feature set in a quarter, the only customers you keep are the ones who would not leave even if the alternatives were free.Loyalty comes from the three points above working together: • People the client knows• Trust earned through delivery• Confidence that you will keep them on the right side of every rule that applies to their moneyCompanies that treat clients as transactions will discover how thin their moat really was.​So where does this leave services and SaaS?For SaaS, the trust and regulatory posture is becoming part of the product itself. If you sell into financial services, your compliance record and the credibility of the team behind the code will show up in procurement before your road map does.For services, the opportunity is bigger than ever, but only for those that combine execution with depth. AI has raised the floor because anyone can deliver code fast. However, it has not raised the ceiling. It’s a fact that clients pay for teams that can build quickly, but also the ones that know which provider to choose, how money should move across borders and what a regulator will object to before the regulator says it.The services firms that are growing in this era combine fast, high-quality engineering delivery with deep domain knowledge in payments, compliance and risk.Strong products and strong ideas are still required, and building them properly still separates winners from the rest. But raw building speed is now table stakes. The durable advantages are human: a team people believe in, expertise that acts as a seal of trust on what you ship, the licenses to operate where your customers live and clients who stay because leaving never crosses their mind. AI may accelerate all of it, but it can’t replace any of them completely.​Forbes Technology Council is an invitation-only community for world-class CIOs, CTOs and technology executives. Do I qualify?
