My biggest advice here is that, especially as you’re starting to build out new workstreams, targeted lists are your best friends. Instead of just running a search for 50k engineers in NYC to send outreach to, try specific subsets of engineers, find what works, and then scale that out to others.
Additionally, using things like audiences to save the data you’ve already enriched, so you don’t enrich it again is key. If audiences isn’t an option for your team, an external snowflake etc can also be super helpful here.
