Manual research is the slow death of outbound scaling, I feel that. The biggest lesson I learned is that you need to shift your focus: it is not about buying a static list of businesses; it is about real time data enrichment. You need a Data Provider that plugs into your CRM via API and validates your contacts the moment you add them, otherwise your Marketing List gets stale immediately. In my own research, one company that stood out is Techsalerator because they offer B2B Data covering over 200 countries, and they provide 100 to 200 fields of context like firmographics and technographics. That deep Business Data helps you segment better so you can prioritize quality leads over just chasing volume.
