- Post on LinkedIn and your community channels
- Email your newsletter or customer base
- Aim for 20–30% funded before public launch
Go live and raise publicly

- Campaign visible to all eligible ProbablyBig investors
- Weekly progress briefings from your Success Manager
- Investor Q&A moderated and answered
- Live analytics dashboard — backers, amounts, conversion

- Funds transferred within 5 business days of close
- SEIS3/EIS3 compliance certificates issued to investors
