Limitations
We're not a full-service marketing agency. We focus on creating and iterating digital products, not campaign execution or ad management.
We're not a data science or AI research firm. While we integrate AI into our workflows, we don't build LLMs or large-scale data infrastructure from scratch.
We're not a mass-production shop. Every project we take on is customized and our priority will always be depth and fit over volume.
