NNexus Data Technology
Data Collection

Source the data that doesn't exist yet

When public datasets run out, Nexus builds proprietary ones — managed field crews, consented contributor panels and synthetic pipelines built to your exact capture spec.

Modalities

Every modality, one accountable program

Mixed-modality projects run under a single delivery lead, schema and QA standard.

Image & Multi-View Video

Calibrated rigs, controlled lighting, staged rare events and time-synced multi-angle capture.

  • Up to 12 synced cameras
  • RAW + encoded delivery
  • Scene coverage matrix

Voice & Multilingual Audio

Scripted, spontaneous and conversational speech across accents, ages and acoustic conditions.

  • 100+ languages
  • Demographic quotas
  • Studio & in-the-wild

Edge Sensor & LiDAR

Vehicle and robot-mounted LiDAR, radar, IMU and GNSS capture with sub-frame synchronisation.

  • ROS bag delivery
  • Calibration files included
  • Route planning included

Text & Document Corpora

Domain document sourcing, expert-written text and structured corpus construction.

  • License-audited
  • Domain expert authoring
  • Deduplicated

Synthetic Generation & Augmentation

Procedural scenes and model-assisted generation to close long-tail coverage gaps privately.

  • Class balancing
  • Privacy-safe
  • Human verification gate

Web Scraping & OSS Curation

Compliant crawling with provenance manifests, license checks and quality filtering.

  • Robots-compliant
  • Provenance manifest
  • Toxicity filtering
Process

From capture spec to delivered dataset

  1. 01

    Capture spec

    We co-author the collection protocol, quotas, metadata schema and acceptance criteria.

  2. 02

    Panel & crew build

    Contributors are recruited, vetted, consented and calibrated against the spec.

  3. 03

    Pilot batch

    A small batch is delivered and reviewed before full-scale capture begins.

  4. 04

    Scaled collection

    Capture runs with live dashboards on quota fill, quality and coverage.

  5. 05

    QA & delivery

    Multi-pass QA, metadata validation and secure handoff with full provenance.
