Yet many organisations struggle to define an AI strategy, develop models and scale solutions responsibly. Global AI consulting firms bridge this gap.

FAQs
What differentiates generative AI consulting from traditional AI consulting? Generative AI focuses on creating new content (text, images, code) rather than analysing existing data. Firms like Xcelacore and Accenture integrate generative AI capabilities into their service portfolios to automate meeting summaries or personalise customer interactions.
How do large consultancies compare with mid‑sized firms? Global consultancies offer scale, broad domain expertise and extensive resources. Mid‑sized firms like Xcelacore provide agility, cost effectiveness and closer client relationships, which can be advantageous for mid‑market organisations.
Is a proprietary AI platform necessary? Proprietary platforms (e.g., Wipro’s AI360 or IBM’s Watsonx) can accelerate delivery and provide reusable components. However, open‑source and cloud‑native approaches can work if paired with the right expertise.
