The market sizing tool within market insights is good. I think it could be improved by allowing users to add search terms rather than just replace, and then combine the results. For example, compliance training has market size of £221.6m. But it's probably indistinguishable as a market sector from regulatory compliance (worth £1.2bn). But I can't combine the two results, only choose one or the other.
Separately, there's probably an issue with data quality here, as the average EBITDA margin for Regulatory Compliance is currently reading as 1,337,458.4%. But this could be a VERY useful feature if it can be tidied up.
