It is very easy to organize and curate data nowadays thanks to Airtable databases and views. Curating data can save time for someone, and it might be valuable if the data serves a business goal such as lead generation.
There are plenty of lead generation tools out there. However, many niches in lead generation are still good ideas to pursue, if you make it focused on a specific audience, such as this one, made for agencies.
