Discover how a Series-B AI startup specializing in natural language processing successfully built a 50M+ record training dataset in just 3 months, accelerating model accuracy and expansion into new verticals.
A Series-B AI startup specializing in natural language processing for enterprise applications. Their core product uses sentiment analysis, entity recognition, and text classification to help brands understand customer feedback at scale. The company had raised $28 million and was under pressure from investors to rapidly improve model accuracy and expand into new verticals.
The client's machine learning team was hitting a critical bottleneck: their models were only as good as their training data, and their training data was not good enough.
Actowiz Solutions worked closely with the client's ML engineering team to design a comprehensive training data pipeline:
| Metric | Before | After Actowiz |
|---|---|---|
| Monthly data volume | 500K records | 17M+ records |
| Data sources | 3 sources | 200+ sources |
| Model accuracy (sentiment) | 78% | 94% |
| Data collection cost | $45K/month | $13.5K/month |
| Engineering time on scraping | 40% of ML team | 0% (fully managed) |
| PII compliance confidence | Low | 99.9% redaction rate |
| Time to new source onboarding | 2-3 weeks | 2-3 days |
The total dataset delivered in the first 3 months exceeded 50 million structured records, providing the foundation for significant model performance improvements across all of the client's NLP products.
"Actowiz did not just solve our data volume problem. They solved our data quality problem, our diversity problem, and our compliance problem all at once. Our ML team went from spending half their time maintaining scrapers to spending 100% of their time improving models. The accuracy improvement from 78% to 94% was a direct result of having better, more diverse training data."
