How to choose a reliable private market data provider?
Usually, data quality is evaluated based on factors such as accuracy, completeness, and uniformity. However, in our experience, there are a few other things to check to ensure you're selecting a reliable data vendor:
Quality and freshness
Record counts and geographic coverage show you the scale of a provider's dataset. But scale without freshness is just a large pile of outdated information. Real-time updates mean those changes are captured as they happen, not discovered weeks later when a campaign has already gone sideways. If the data provider keeps the data fresh at all times, it also reflects how reliable the provider is. Professional providers let you see the last update date for each record.
Prompt and transparent communication
Being able to get all the relevant information about data quality, fill rates, data structure, and features mentioned above prior to purchasing data solutions also shows that the data provider is transparent and can be trusted. At Coresignal, we provide information about all these metrics to our potential clients, and we can guarantee stable data delivery and consistent data structure.
Secure and responsible data collection
Experienced and reliable data providers are committed to ethical collection of public web data and prioritize data security. Before making a decision, evaluate if the data provider is transparent about its data privacy practices, which will help you make an informed decision.
Test first
Lastly, it’s essential to test and see if the data you’re getting from the provider meets your business needs and expectations. We encourage you to share what information is needed for you to evaluate our data and we are ready to provide the resources that would be most helpful in testing our datasets or other data solutions.
