## Runnable Narrative

This stack runs cold outbound end to end from a single Yalc prompt. Crustdata sources accounts and people. FullEnrich enriches missing emails. Instantly sends the email sequence. Unipile fires LinkedIn invites in parallel for the highest fit subset. Notion holds campaign state and reply logs.

The prompt below clones into Claude Code, configures the workflow against your own credentials, and runs end to end. You stay in the loop on send approval (no auto fire) but everything else is orchestrated.

## Runnable Prompt

# Clone the Yalc skill set
gh repo clone Othmane-Khadri/YALC-the-GTM-operating-system && cd YALC-the-GTM-operating-system

# Configure your env (Crustdata key, FullEnrich key, Instantly key, Unipile DSN, Notion key)
cp .env.example .env && $EDITOR .env

# Run the campaign workflow
claude
> Yalc, build a Q3 outbound campaign for Series A B2B SaaS founders in DACH.
> Source 200 leads via Crustdata. Enrich missing emails via FullEnrich.
> Draft a 3 step email sequence in [client voice]. Push to Instantly (paused).
> In parallel, queue LinkedIn invites via Unipile for the top 50 fit scores.
> Log every action and reply to the "Q3 outbound" Notion campaign.

## Variations

- Swap Instantly for Smartlead when you need fine grained send rule control or unlimited inboxes per seat.
- Swap Unipile for HeyReach when the LinkedIn sender count is above 5 and the agency economics make sense.
- Add Predictleads on top to trigger sequences on hiring signals or financing events instead of static ICP filters.
- Swap Notion for HubSpot when the team needs deal pipeline UX and sales suite features.
