The six stages

01

Apply

1–2 days

Complete our founder application — company basics, your raise size, SEIS/EIS status, and a short description of what you are building. We review every application within 2 business days.

  • Company registration number
  • Draft raise size and equity offered
  • SEIS or EIS Advance Assurance (or confirmation you are applying)
  • A short pitch: the problem, your solution, why you
02

Onboard with your Founder Success Manager

3–5 days

Once approved, a dedicated Founder Success Manager is assigned. They will help you structure your pitch, review your campaign materials, and advise on your fundraising strategy.

  • Kickoff call with your Success Manager
  • Campaign narrative and key metrics review
  • Valuation and equity offer sense-check
  • Investor Q&A template preparation
03

Build your campaign page

3–7 days

Using our campaign builder, you add your video, pitch deck, team bios, financial highlights, and risk disclosures. Our compliance team reviews everything before publishing.

  • Founder video (2–3 mins, shot on phone is fine)
  • Pitch deck or executive summary
  • Financial highlights: revenue, growth, burn
  • Key highlights and investment case
04

Pre-launch warm-up

1 week

Before going public, you get a private link to share with your warm network. This creates momentum — campaigns that open with 20–30% raised convert at 3x the rate of cold-launch campaigns.

  • Share private link with friends, family, and angels you know
  • Post on LinkedIn and your community channels
  • Email your newsletter or customer base
  • Aim for 20–30% funded before public launch
05

Go live and raise publicly

4–8 weeks

Your campaign goes live to the ProbablyBig investor community. Your Success Manager will keep you updated on progress, help with investor questions, and advise on momentum tactics if needed.

  • 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
06

Close and issue shares

2–4 weeks post-close

When your raise closes successfully, we facilitate the share issuance process, send SEIS3/EIS3 forms to investors, and transfer the net proceeds to your company bank account.

  • Funds transferred within 5 business days of close
  • SEIS3/EIS3 compliance certificates issued to investors
  • Cap table and shareholder register updated
  • Investor update cadence begins
