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:
- Open the round — define the name, type, expected valuation, share class
- Close the round — list each investor and their allocation, atomically issue every share transaction + update the cap table
How to open a round
- Go to Company → Funding Rounds
- Click New round
- Enter the name (e.g.
Series A) and type (pricedfor an equity round) - Add the target pre-money valuation and price per share if known (you can leave blank and add later)
- Pick the share class the round will issue (typically the same class for the whole round)
- Optionally pick the lead investor
- 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
- Go to Funding Rounds and click the Close action on your open round
- Confirm the share class, price per share, pre-money valuation, and close date
- Add an investor allocation for each cheque — shareholder + shares + (optional) consideration in £. If you leave consideration blank, Blankitt computes it as shares × price.
- Click Preview dilution → to see how existing holders' percentages shift after the round
- 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.
