        What is the impact of this?

        Efficiency gains will increase demand for developers

        At first glance, it seems logical to assume that a sharp increase in productivity would reduce the need for resources, such as developers since the same amount of work can be achieved with fewer people. 

        However, we believe the opposite will occur: as software becomes more affordable, the demand for software products will grow as it will be cheaper than ever to produce. This pattern, known as Jevons Paradox, has a historical precedent: when steam engines became more fuel-efficient in the 19th century, coal consumption didn’t decrease. Instead, it soared as cheaper and more efficient engines drove expanded use across industries.

        Similarly, the Lump of Labor Fallacy mistakenly assumes that technological advancements reduce the need for human labor by replacing tasks with automation. However, history shows that innovation creates new types of work, shifting industries and roles. In software development, AI tools don't replace developers; they complement them, handling routine tasks to free up developers for more strategic, creative work.
        AI in code generation tools, (IDEs), and LLMs, has revolutionized how developers approach coding. These advancements allow developers to automate repetitive tasks, detect bugs faster, and predict the outcome of certain coding patterns or architectural decisions.
        The result is a significant increase in productivity —freeing up time and mental energy for more creative, strategic, and problem-solving aspects of development.

        We’re already seeing a similar trend among our clients. As development processes become faster and more cost-effective, clients are increasing their investment in custom software solutions rather than reducing it.At Proxify, this trend will continue, leading to a greater demand for innovative, tailored software.

        Additionally, we foresee a shift in the developer’s role. The ability to bridge complex business needs with technical solutions—traditionally a product manager’s skill set—will become even more essential. Developers who can translate nuanced business challenges into effective software will be invaluable in this evolving landscape.

            Why custom software in the age of AI?

            Companies today invest heavily in SaaS software – up to $11,200 per employee annually.
            While SaaS solutions offer quick deployment and low upfront costs, they rarely effectively meet specific business needs as custom software.

            Why custom software will (almost) always be superior

            Custom software often outperforms SaaS because it's tailored to specific business needs. While SaaS platforms with AI offer general-purpose tools, they can lack customization, flexibility, and scalability as businesses grow.

            Think about it: was that support center software truly delivering a seamless experience for your customers? Did your CRM genuinely adapt to the needs of your sales team, or were you constantly adjusting to its limitations? Were you able to drive adoption for the dashboard you built, or did frustrations arise from the lack of real-time data and limited customization options? And that eCommerce platform you launched—was it equipped to handle complex pricing rules, personalized product recommendations, dynamic bundling, and a customized checkout flow?

            Forward-thinking companies like Klarna understand this. They chose to build custom solutions to replace software like Salesforce and Workday. While Klarna is on the far end of the spectrum, our own journey at Proxify demonstrates the impact of custom software. We wouldn't have scaled to where we are today without our custom-built tools—from an applicant tracking system to an AI-powered matching platform that enables unique matches in minutes, a task that would take human teams days, if not months, to accomplish.

            KEY INSIGHT
            In-house custom software offers numerous benefits, including customization, privacy and security, compliance and control, integration with existing systems, long-term efficiency and building internal expertise and future-proofing.

            Developers' evolving roles in the AI era

            With AI automating many routine tasks, our assumption is that developers' roles will evolve beyond coding into strategic and creative functions. They will be increasingly recognized for their unique contributions – creativity, intuition, and problem-solving. Their work remains essential as they translate complex business needs into functional, scalable solutions, giving organizations a competitive edge in the digital landscape. While AI boosts productivity, the human element in development – adaptability, innovation, and collaboration – remains irreplaceable. Developers will be technology builders and enablers of progress, pushing the boundaries of what technology can achieve.

            KEY INSIGHT
            As AI automates routine tasks, developers will shift focus to more strategic and creative roles, using their unique skills to translate complex needs into scalable solutions.

            More software, more possibilities

            AI-driven development tools are leveling the playing field, allowing businesses of all sizes to innovate like never before. What was once exclusive to large enterprises is now accessible to startups and mid-sized companies, enabling faster, more tailored solutions. This shift isn't just about more software – it's about creating relevant, high-quality applications that align with unique business needs. With custom software now within reach, companies can continuously innovate, iterate quickly, and adapt to changing market demands, moving beyond the limitations of generic, off-the-shelf solutions.

            KEY INSIGHT
            AI tools democratize custom software development, enabling startups and SMBs to innovate, iterate rapidly, and meet unique market demands on par with larger enterprises.

            Conclusion

            AI-driven development tools have made custom software more accessible, empowering developers to move beyond routine tasks and focus on innovative, high-impact work. By automating repetitive tasks, AI frees up time for developers to optimize systems, design unique features, and address strategic challenges—enhancing both their role and the software's effectiveness. This shift boosts developer productivity and gives businesses a competitive edge by fostering continuous improvement and rapid adaptation.

            As AI reshapes development, the decision between building custom software and purchasing off-the-shelf solutions has become more critical. Off-the-shelf SaaS products offer fast, cost-effective solutions but can lack the flexibility and customization that evolving businesses need. Custom software, however, enables companies to tailor solutions precisely to their workflows, unlocking greater adaptability, scalability, and alignment with business goals.

              When to build and when to buy

              When to build

              Build custom software if your business has unique workflows, scalability requirements, or specific challenges that generic solutions cannot address. Custom solutions offer flexibility, greater control, and better integration with your existing systems.

              When to buy

              Buy off-the-shelf if you need quick deployment, lower upfront costs, and if the software’s generic capabilities align closely with your needs. SaaS solutions are often ideal for standardized processes that do not require extensive customization.

              AI tools now enable businesses of all sizes to innovate, helping teams continuously iterate and tailor solutions to ever-changing needs. The future of software is here, and a blend of human ingenuity and AI-powered efficiency drives it.
