GTM Stack · Updated June 2026

Common questions
Stack questions I get all the time
Attio is the default choice for relationship-led teams: VC funds, PE firms, agencies, and B2B SaaS companies that outgrew HubSpot or Pipedrive. It has a flexible object model, native AI, and an API that plays nicely with every tool on this page. I run it at the center of every GTM stack I build.
Lemlist is my go-to for multichannel (email + LinkedIn + WhatsApp in one sequence). SmartLead and Instantly are better for pure email volume at scale with unlimited mailboxes. If you need LinkedIn in the same sequence, Lemlist or LaGrowthMachine. If you need scale above 50k sends per month, SmartLead.
Clay is the most powerful: it composes waterfalls across dozens of providers and writes cleanly to Attio via API. For simpler enrichment at lower cost, BetterContact (best for EU phone numbers) or Fullenrich. For email-only at scale, FindyMail has the highest deliverability focus.
n8n is what I use on every client engagement. It is open-source, self-hostable, and the webhook/API handling is the cleanest of any automation tool. Make.com is a good alternative for teams without a technical person. Both connect to Attio via the REST API.
No. A typical early-stage stack is: Attio (CRM) + Apollo or Clay (leads and enrichment) + Lemlist or Instantly (outreach) + n8n (automation). That covers 90% of what you need. The rest are for specific use cases: signals, LinkedIn scale, visitor ID, meeting notes. Add them when the need is clear, not before.
