Automotive & Machinery Software Development

We build custom software, AI, machine learning, analytics, APIs, fleet systems and engineering platforms for automotive, machinery and industrial businesses.

Tell us the automotive or machinery problem you need to solve. We design the architecture, develop the software, build the analytical or machine-learning models, integrate the system and deploy it into production.

Domain firstWe run a vehicle and machinery specification database ourselves, so we understand engines, configurations, telemetry and service data.
Data & ML depthPhD-level machine learning and statistics, applied to prediction, valuation, forecasting and anomaly detection.
Full stackFrom PostgreSQL and ETL pipelines to APIs, dashboards, mobile apps and cloud deployment.
