Sequential IDs expose sensitive data and make it easy to enumerate. Learn why and how Capsens switched to v7 UUIDs in its Rails apps.

With the entry into force of the European Data Governance Act, all investment platforms are required to increase the transparency and protection of customer data. According to the KPMG “European Financial Regulation Outlook 2024” report, more than 70% of fintech executives believe that regulatory compliance will be their main challenge in the coming years. Fines linked to breaches in data management can reach 4% of annual turnover (source: European Commission, RGPD). This pressure makes players in the sector responsible: without a redesigned technical architecture, it is difficult to offer the secure monitoring and automated management required by law.

Integrating artificial intelligence into web developer workflows has never made more sense than it does today. According to GitHub (“The State of AI in Software Development”, 2023), the use of AI assistants can reduce the time spent on certain repetitive coding tasks or looking for bugs by up to 55%. Test automation, documentation generation, and code suggestions are becoming essential allies in accelerating delivery without sacrificing quality. This time saving frees up the developer for tasks with higher added value, such as design or architecture.

Investor behavior has changed profoundly: today, mobility is essential. According to a McKinsey study (“Digital Investment in Europe 2023”), 68% of young investors mainly use their smartphone to track their investments or place orders. This figure even climbs to 80% among those under 35. Depriving yourself of a mobile application is therefore tantamount to ignoring the main interface of the new generation of investors.

The DNA of a startup lies in its ability to reinvent itself and accelerate in changing markets. This dynamism depends directly on the freedom of action and experimentation offered to all teams. According to a study by Harvard Business Review (“The Secret of High-Performing Startups”, 2023), 74% of the most successful startups actively encourage initiative taking — whether by testing new tools, launching a side project or by developing a new product based on an internal idea. This climate of trust amplifies responsiveness and agility, two essential qualities to ensure the rapid growth that characterizes the startup model.

Until a year ago, using AI to code was a matter of curiosity. A gadget, a slightly doped autocomplete, something we tested on Friday afternoon between two deployments. Today, in February 2026, Claude Code is in the process of fundamentally redesigning the way developers work. And while some teams are increasing their delivery capacity by two or three, others continue to code exactly as in 2023.

In a sector where speed of execution and reliability are non-negotiable, automation is becoming much more than a simple advantage: it is a real necessity for financial players. And when you think of automation and AI, it's hard to miss solutions like Claude IA, which are disrupting daily uses. But in concrete terms, why is this automation essential today? Here is a numerical and illustrated overview to understand what is at stake.

When we talk about AI and automation, Claude now has a very special place on the tech scene. But the release of the Opus 4.6 model is much more than just a small step forward: it is a major evolution for anyone — or structure — looking to better automate everyday tasks with an AI that really understands what's going on.

Digital transformation has profoundly transformed the financial sector in recent years.
