How Anthropic Uses Claude in GTM Engineering: Building CLAFTS with Claude Code

Jared Sires, GTM Product Manager (formerly account executive) at Anthropic, describes building CLAFTS (Claude Drafts) — an AI email assistant powered by the Claude API — with zero prior coding experience, using Claude Code. The tool automates customer email drafting by combining a personalized system prompt, context retrieval from Google Docs and web URLs, and pattern matching, saving Sires 2–3 hours per day and enabling a career shift from sales to go-to-market architecture.

Key Takeaways

• A non-technical AE built a production-grade internal tool using Claude Code without prior coding skills 0:06
• CLAFTS addresses a concrete GTM pain point: managing 600–700 accounts and answering emails until 8–9 PM 0:24
• The tool uses RAG-style context retrieval — pulling from Google Docs, internal knowledge bases, and live web URLs — to ground email drafts in accurate product information 1:17
• CLAFTS has sent thousands of emails and saves Sires an estimated 2–3 hours daily 1:55
• Sires argues the "technical barrier dissolving" lets non-engineers design products and collaborate with senior engineers to bring them to completion 2:02

Problem: Administrative Overload in Sales

Sires describes a typical startup AE workload: managing 600–700 accounts 0:24, working until 8–9 PM answering emails, and manually scouring Slack, knowledge bases, Google Docs, and Google Drive to compose responses 0:30. This fragmentation of information across tools was the direct motivation for building CLAFTS.

How CLAFTS Works

The workflow has three components 0:57:

1. System prompt generation — the user inputs their name, role (e.g., account executive), and use case; the tool auto-generates a prompt via the Claude API 1:03
2. Context retrieval — integrates with Google Docs and can fetch live web URLs (e.g., Claude documentation pages) to build a real-time knowledge context 1:17
3. Draft generation — clicking "Generate Draft" on a selected email triggers Claude to retrieve relevant internal and external documentation and compose a contextually accurate reply 1:32

Sires notes this allows him to "speak more technically with customers" without needing to context-switch across tools 1:43.

Career Impact and the Dissolving Technical Barrier

Sires frames CLAFTS not just as a productivity tool but as a career-transforming one: it enabled his transition from account executive to go-to-market architect at Anthropic 2:11. He advocates that lowering the technical barrier lets non-engineers focus on product design and collaborate with senior engineers for final implementation 2:06, rather than being blocked entirely from building.
