Start with your target data and how much maintenance you can stomach. If you need live, unstructured harvests across dynamic sites, proxy-first providers with strong unblockers make sense. If you want business entities, jobs, or people data packaged and clean, curated datasets and APIs reduce engineering lift. Blend both when you must — a pragmatic mix drawn from top AI data collection companies powering LLMs.
Scrutinize sourcing, compliance posture, and the boring but vital pieces — SLAs, QA, deduplication, and freshness metrics. Favor trials and self-serve tiers to pressure-test speed, accuracy, and support before traffic ramps. Keep a backup vendor to absorb spikes or site changes without downtime. Teams that value simplicity and predictable spend often get the best results from the best AI data collection services.
