What does your GTM engineering stack look like beyond Clay and Apollo?

I've spent a lot of time working closely with different gtm products and one pattern i keep seeing is that most GTM engineering setups start with Apollo for contact scraping and Clay for waterfall enrichment tables. It works fine for basic ICP list building but as soon as you try to build an autonomous pipeline or monitor live buying intent, the table and credit architecture hits real friction and also running scrapers inside spreadsheet rows gets expensive quickly and you spend more time fixing broken webhooks and dealing with contact decay than actually acting on signals. When teams move past basic waterfall tables, the stack usually splits into two layers: contact enrichment tools and dedicated market intelligence infrastructure. Enrichment tools like Clay and Apollo are great when you already know the account and just need to query external APIs for a phone number, verified email, or linkedin but they aren't built to continuously listen to a market. For persistent monitoring, platforms like scale intelligence handle the underlying data layer where it continuously monitors over 75 sources (including reddit, github, linkedIn, registries, and hiring boards). It maps those disparate events into a deterministic buyer graph, verifies the exact evidence behind every lead and scores compound intent into tiers before triggering downstream workflows or routing to human reps.
