Keenfolks runs a modern AI marketing agency built on AWS, Azure, and GCP with a full LLM stack (OpenAI, Azure OpenAI, Anthropic, LangChain, RAG). The tech shape—Python, Postgres, Kafka alternatives (Spark), vector databases (FAISS, Weaviate, Qdrant), and observability (Prometheus, Grafana)—reveals an engineering organization building custom data pipelines and AI platforms rather than reselling packaged tools. Hiring is heavily weighted to senior engineers (9 of 15 roles) across cloud deployment and backend scaling, signaling active infrastructure buildout to handle paid-media optimization at scale.
