GTM tools FAQ
What tools does a GTM engineer use?
Usually a data layer (Deepline or Clay over many providers), a CRM such as Attio or HubSpot, a cold email sender like Instantly, a LinkedIn tool like HeyReach, verification, and a way to run code or scheduled jobs. The rest depends on the motion.
What is the best GTM tool stack for a startup?
For a seed to Series A B2B startup: one CRM (Attio or HubSpot), one data and enrichment layer over several providers (Deepline or Clay), an email verifier, a cold email sender such as Instantly on secondary domains, a LinkedIn tool such as HeyReach, and a call recorder like Granola. OneGTM runs its own outbound on Attio, Deepline, Instantly, HeyReach, and Granola. Add signal tools and a dialer only when a specific job needs them.
How many GTM tools does a startup need?
Fewer than most buy. One data layer, one CRM, one email sender, and one LinkedIn tool cover most early outbound. Add dialers, signal tools, and call recording when a specific job needs them.
Are these rankings paid?
No. Vendors cannot buy a spot. Some links are referral links that may earn us a credit, which never changes what you pay or who is listed.
