GTM Stack 2026: What Actually Works

A r/ClaudeGTM thread asked "what's your GTM stack in 2026?" and the answers split cleanly into three camps: legacy teams paying $20K+ per year for Apollo plus ZoomInfo plus an enterprise sequencer; mid-market teams running Clay plus Smartlead plus four enrichment vendors; and a growing set of small teams running a code-first stack that costs under $200/mo and outperforms both. This post covers what is actually working in the third group.

The Three Camps

Camp 1 is the enterprise stack: Apollo SalesOS plus ZoomInfo plus Outreach. Reliable, expensive, slow to iterate. Camp 2 is the Clay-led stack: visual waterfalls, multi-vendor enrichment, $1K to $5K per month at steady state. Camp 3 is the code-first stack: a multi-platform search API plus a few focused vendors plus orchestration in Claude Code or n8n.

The Code-First Stack

1. Discovery: Scavio for SERP plus Reddit plus YouTube. One credit pool, one API key, $30/mo for 7,000 credits.
2. Verified emails: a focused emails-only vendor like ZeroBounce or NeverBounce, paid per verification.
3. Sequencer: Smartlead at $39/mo or Instantly at $37/mo. Both reliable and cheap.
4. Orchestration: Claude Code skills or n8n workflows. Claude Code wins for branching reasoning; n8n wins for predictable, schedulable steps.
5. CRM: HubSpot Free or Pipedrive Essential. Both cheap, both API-friendly.

Why the Code-First Stack Wins

The wins are predictability and control. Apollo's data refresh cadence is opaque. Clay's per-action pricing surprises teams at scale. The code-first stack is a credit pool plus a sequencer subscription plus emails-per-verification. Forecasting is addition, not multiplication.

The control matters because GTM is opinionated work. Every team has their own ICP, their own scoring formula, their own sequencer cadence. Tools that bake one opinion into a UI lose to tools that expose the data and let the team write theirs.

The Discovery Layer in Practice

Most prospect research in 2026 looks like this: take a company domain, return public LinkedIn signals, recent news, Reddit mentions, and a brand SERP snapshot. One API call covers the SERP plus Reddit portion; a second covers public LinkedIn via a `site:linkedin.com/in` filter.

import os, requests

API_KEY = os.environ["SCAVIO_API_KEY"]
H = {"x-api-key": API_KEY}

def discover(domain: str, exec_name: str) -> dict:
    serp = requests.post("https://api.scavio.dev/api/v1/google",
        headers=H, json={"query": f"site:linkedin.com/in {exec_name}"}).json()
    rdt = requests.post("https://api.scavio.dev/api/v1/reddit/search",
        headers=H, json={"query": domain}).json()
    brand = requests.post("https://api.scavio.dev/api/v1/google",
        headers=H, json={"query": domain, "include_ai_overview": True}).json()
    return {
        "linkedin": serp.get("organic_results", [])[:3],
        "reddit_mentions": rdt.get("posts", [])[:5],
        "brand_serp": brand.get("organic_results", [])[:5],
        "ai_overview": brand.get("ai_overview"),
    }

The Sequencer Choice

Smartlead and Instantly trade leads in this category. Both are reliable and both are cheap. Smartlead has a slight edge on inbox warmup and deliverability tooling; Instantly has a slight edge on UX. The decision is rarely consequential.

Where Claude Code Fits

Claude Code is the new sleeper in the GTM stack. The Claude Code skills pattern (one markdown file per repeatable workflow) replaces glue code that used to live in n8n nodes. The skill calls Scavio, parses the result, scores against ICP, and writes to the CRM. Each skill is short enough to read in one screen.

The Wrong Reasons People Stay on Apollo

Inertia, integration depth, and contract terms. None of those are product wins. Teams that switched in 2026 typically saved 60 to 80% on spend and gained more flexibility. The migration is a 2-week project for most teams.

What This Stack Cannot Do

It does not write outbound sequences for you. It does not magically produce verified enterprise emails. It does not replace a great SDR. It is a data layer plus an orchestration layer; the human strategy and copy still matter.

Total Monthly Cost

Discovery $30 plus emails per-verify ($30 to $80) plus sequencer $39 plus CRM (free to $29) plus Claude API or n8n ($20 to $50). Total $120 to $230 per month for a small team. Same job that Apollo SalesOS bills $20K+/yr for, depending on seat count.
