17 de October, 2025
2025 Confirmed What Had Been Suspected for Years: Artificial Intelligence Is No Longer a Luxury—It’s a Key Element in Any Startup’s Survival. AI tools that were once used experimentally are now a core part of the growth stack, from customer service to data-driven decision-making.
