Workflow
Step 1: Diagnose Stage & Sales Motion
Ask: "Where are you in your sales journey?"
| Stage | Signals | Focus | |-------|---------|-------| | Pre-sales | No paying customers, still validating | → Founder selling, discovery calls | | First 10 customers | Closing initial deals, learning process | → Sales process documentation | | 10-50 customers | Repeatable motion emerging | → CRM setup, pipeline management | | Scaling | Hiring first sales reps | → Playbook, forecasting, team |
Sales Motion Selection:
| Your Product | ACV Range | Recommended Motion | |--------------|-----------|-------------------| | Self-serve tool | 14 days)
- Validate close dates and amounts
- Update forecast (commit, best case, pipeline)

Common Sales Mistakes
Process Mistakes:
- No defined stages — Deals get stuck, no visibility
- Skipping discovery — Demo without understanding pain = low close rate
- Feature dumping — Showing everything instead of solving their problem
- No mutual action plan — Hoping vs. driving deals forward
- Single-threaded — Only one contact = deal dies when they leave
Outreach Mistakes:
- Too much "I/we" — Make it about them, not you
- No personalization — Generic = ignored
- Asking for too much — "30 min call" vs. "quick question"
- Giving up too early — Most responses come after 3+ touches
- No follow-up system — Leads fall through cracks
Forecasting Mistakes:
- Hoping vs. knowing — Commit only what you can defend
- Outdated close dates — Update weekly or forecast is fiction
- Ignoring stuck deals — If no activity for 2 weeks, it's not real
- Single best-case scenario — Always have commit/best case/pipeline
