Planning and closing a funding round

Cap table: open a round, preview dilution, then atomically close with all the investor allocations.

What it does

A funding round is a way to group multiple share issuances on the same terms. Pre-seed, Seed, Series A — each is a round with a single pre-money valuation, a single price per share, and 1-20 investor allocations.

Blankitt models a round as a two-step flow:

  1. Open the round — define the name, type, expected valuation, share class
  2. Close the round — list each investor and their allocation, atomically issue every share transaction + update the cap table

How to open a round

  1. Go to Company → Funding Rounds
  2. Click New round
  3. Enter the name (e.g. Series A) and type (priced for an equity round)
  4. Add the target pre-money valuation and price per share if known (you can leave blank and add later)
  5. Pick the share class the round will issue (typically the same class for the whole round)
  6. Optionally pick the lead investor
  7. Click Create round

The round is now open. Investors can be added incrementally if you want, or all at close.

How to close a round

  1. Go to Funding Rounds and click the Close action on your open round
  2. Confirm the share class, price per share, pre-money valuation, and close date
  3. Add an investor allocation for each cheque — shareholder + shares + (optional) consideration in £. If you leave consideration blank, Blankitt computes it as shares × price.
  4. Click Preview dilution → to see how existing holders' percentages shift after the round
  5. Click Close round + issue shares to commit

Behind the scenes, Blankitt:

  • Issues a share transaction per investor
  • UPSERTs each holder's row on the cap table
  • Bumps the share class's issued-share count
  • Closes the round with cached totals (total raised, post-money)

All in a single atomic batch — a partial close can't happen.

Tips

  • Open the round before investors start signing — the round can collect terms incrementally as the lead is agreed
  • The dilution preview is pure-read, so click it as many times as you want to validate the numbers before committing
  • If you're also converting a SAFE in the round, convert the SAFE first (it issues shares at the cap or discount price) then close the round with the priced-investor allocations
  • Each investor must already be on the s113 register. Admit them via Shareholders → Admit if not.
