Technologies AI software development: AIaaS vs. open-source vs. bespoke - Which is best?

Artificial intelligence (AI) represents a significant shift, promising to transform operations and drive innovation across industries. With the AI software market projected to hit $2 trillion by 2030 and more than half of businesses already integrating AI into their operations, the excitement around AI's potential is palpable. Yet, it poses challenges for many entrepreneurs.

As an experienced agency in the domain of Artificial Intelligence, we stand ready to guide you through these challenges. While over 76% of enterprises planned to increase their AI investments in 2023, we understand the challenges of adopting and scaling this technology.

Let us be your ally in creating AI software to unlock its power with confidence and precision.

What is AI software?

AI software refers to apps, websites, or programs that are powered by artificial intelligence to perform tasks that usually require human intelligence. These applications can range from chatbots that help answer your questions and recommendation systems on shopping sites that suggest products you may like, to more complex programs that can analyze large sets of data to find patterns.

Unlike traditional software that follows a strict set of rules, AI applications learn from the data they process, allowing them to improve over time and make decisions or provide insights that weren't explicitly programmed into them. For example, this is the case with AI chatbots.
