Data Collection Services for ML

We understand how and why your data will be used. That’s why we align every source and collection method with your strategy.

High-quality data without hiring or managing a team
Structured workflows and flexible solutions for unique tasks
Only your goals drive the process — not our internal tools or templates

What is Data Collection?

The systematic process of gathering, cleaning, and organizing information to train effective machine learning systems. High-quality data enables accurate predictions, reduces bias, and streamlines development while maintaining compliance.
Key Benefits:

  • Superior Accuracy — Clean, relevant data builds more precise models
  • Reduced Bias — Representative datasets minimize unfair outcomes
  • Faster Deployment — Optimized collection shortens development cycles
  • Regulatory Ready — Built-in compliance (GDPR, CCPA, etc.)

Quality In = Quality Out

Your AI is only as good as the data it learns from.

Managing Data Collection is Hard—We De-Risk It

From project brief to results, we support business and product teams in collecting data across formats — fast and securely.

On your own, it’s risky:

  • No internal team or structured setup in place
  • Unclear how to manage and track multiple tasks
  • Without expert review, incomplete or irrelevant data often goes unnoticed
  • Missed deadlines delay model training and product launches

With us, it’s under control:

  • We already have experts, right tools, and a proven launch plan
  • Our project manager oversees everything from start to finish — no chaos, no missed steps
  • Built-in validation system ensures high-quality data
  • You get a production-ready dataset exactly when you need it
Start your project faster with clean and validated data

Data Collection Methods

Rendering synthetic data

Creating qualitative data based on specific parameters to model non-existent scenarios. An ideal solution when real-world data is limited or unavailable.

Crowdsourcing

Collection of data from a wide audience using online sources. Allows for obtaining diverse and accurate information for training models.

Selecting open source datasets

Searching, filtering, and preparing data from open sources and data marketplaces according to technical specifications.

In-house data collection

Structured offline collection across diverse formats. All processes are coordinated internally to ensure accuracy and efficiency.

Data Collection Stages

Collection

Selecting appropriate tools and methods for data search according to the technical specifications and business goals.

Cleaning

Structuring and classifying the data by specified attributes to create a high-quality dataset and train the neural network on clean data.

Preparation

Preparing the dataset and metadata in the requested format. Transferring exclusive usage rights and signing all closing documents.

Augmentation

Generating data based on existing datasets using various distortion techniques (shape, color, tilt, etc.), and adding or mixing objects.

Types of Data

Text

Multilingual text data from various sources — used for training chatbots, sentiment analysis, and other NLP tasks.

Images

All types of image data for computer vision: real-world photos, biometrics, synthetic documents, and more.

Video

Specialized recordings for object tracking, traffic analysis, face recognition, and complex video-based applications.

Audio

Collecting voice samples, speech, dialogues, and commands — in a variety of languages and accents.

Lidar

Lidar data from dynamic and static scenes — captured across a range of indoor and outdoor environments.

Dicom

CT, MRI, and X-ray images in DICOM format — collected and structured for computer vision in healthcare.
