# Nullmax

> Nullmax is an AI company building vision-only, map-free autonomous driving software for mass-produced cars. Founded in Silicon Valley in 2016 by former Tesla Autopilot engineer Lei Xu and headquartered in Shanghai, it develops MaxDrive, a chip- and sensor-agnostic driving stack, and Nullmax Intelligence (NI), an end-to-end, multimodal system that reads the road with cameras instead of lidar or high-definition maps. Its technology ships in production vehicles from major Chinese automakers.

- **Founded:** 2016
- **Headquarters:** Shanghai, China (founded in Silicon Valley; U.S. office in Fremont, California)
- **Founders:** Lei Xu (Founder, CEO & CTO), Justin Song (Co-founder & COO)
- **Team size:** ~41 employees
- **Products:** MaxDrive, Nullmax Intelligence (NI), Foundation Architecture
- **Notable:** Founded by a former core member of the Tesla Autopilot team (Autopilot 1.0 and 2.0)., Autonomous driving technology deployed in mass-produced vehicles from major Chinese OEMs., Runs full-scenario self-driving on under 100 TOPS of sparse compute - notably low for the category.

## Products & services

- **MaxDrive** — A platform-based automated driving solution that is chip- and sensor-agnostic, supporting a range of computing platforms (TI TDA4, NVIDIA Orin) and sensor configurations for OEMs and Tier 1 suppliers.
- **Nullmax Intelligence (NI)** — An end-to-end, vision-only, map-free, multimodal autonomous driving system that takes camera, voice, text and gesture inputs and outputs scene descriptions and driving behavior, running on under 100 TOPS of sparse compute.
- **Foundation Architecture** — A dual-platform system pairing a data infrastructure platform with an algorithm development platform, using AI-generated (AIGC) virtual data to cover rare corner cases.

## Achievements

- Founded by a former core member of the Tesla Autopilot team (Autopilot 1.0 and 2.0).
- Autonomous driving technology deployed in mass-produced vehicles from major Chinese OEMs.
- Runs full-scenario self-driving on under 100 TOPS of sparse compute - notably low for the category.
- One of few companies with mass-production capability across multiple different computing platforms.
- Raised roughly $126-142M across strategic, Series A, B, and C rounds.

## Latest updates

- **2025-12** — Closed a Series C funding round (latest tranche around $19.45M), continuing to fund mass-production and global expansion.
