45level GmbH is a software engineering and consulting company. We work with enterprises from the first strategy discussion through architecture and implementation to running systems in production, and we build and operate digital products of our own.
- Data and analytics. Platform architecture, data engineering and advanced analytics on Databricks, SAP HANA, PostgreSQL, DuckDB, Kafka and the major clouds. We are vendor-neutral, so the problem decides the tool.
- AI and agents. Agent-driven business processes, multi-agent systems and retrieval over company data, using models from Anthropic, OpenAI, Google and xAI.
- Software products. Concept, design and engineering of digital products up to market launch, for clients and for our own portfolio.
- Strategy and architecture. Data and AI strategy, target architectures and technology selection, from the first workshop to a delivery plan.
Our engine work happens mostly in Rust. Python, C and TypeScript cover the rest.
AM/Flux is our in-memory engine for dimensional data. People and AI agents ask for business figures at any level of aggregation and get answers directly from memory. Our short version: Memory, not Database.
AM/Flux is closed source. More at analyticalmemory.com.
