What tech stack does Waymo use?

Waymo's backend and on-vehicle systems are built primarily in C++ (for performance-critical perception, prediction and planning) and Python (for tooling, data pipelines and ML workflows) — both are visible in the publicly released Waymo Open Dataset library, which ships custom TensorFlow ops written in C++ and Python.

For infrastructure, Waymo leans on Google Cloud as an Alphabet subsidiary: research and tooling reference Google Cloud Storage for data and Google's compute (GPUs and TPUs) for training. The autonomy software also runs on custom on-vehicle compute — the sixth-generation Waymo Driver integrates cameras, lidar and radar with onboard processing for real-time decisions.

On the rider side, Waymo ships native iOS and Android apps (the Waymo One app) for booking, plus an in-vehicle screen experience. The consumer product surface is mobile-first, consistent with a ride-hailing service.

On data, Waymo's ML pipelines use TensorFlow with data stored and processed in Google Cloud (Cloud Storage, and BigQuery for analytics-scale work is a reasonable read given the Alphabet stack). Public signals don't reliably expose Waymo's internal GTM/CRM tooling, so we don't list specific sales or marketing vendors — only technologies with a real public signal are included here.

Waymo is a deeply technical, build-heavy Google-native shop: a strong C++/Python/TensorFlow core on Google Cloud, with custom hardware. For vendors, that means a high build-vs-buy bar on anything close to the autonomy stack or core infrastructure — pitching to replace internal ML or compute is a hard sell.

The realistic openings are adjacent to the core: rider-facing product analytics, payments, support/CX tooling, marketing and growth, fleet/operations software, and security/compliance — areas that scale with rides and cities rather than with the self-driving research. Because it's an Alphabet subsidiary, expect strong Google Cloud alignment and Google-grade security review, so integrations and pitches that complement (not displace) Google Cloud will land better.
