Startup fundraising, without the paperwork
Undo Capital is the all-in-one platform to run a startup funding round in the UK. Pick your round type, set your terms, generate the legal documents, invite investors to e-sign and update your cap table, from first cheque to close.

Choose how to run your funding round and close in one place
Three ways to raise, each with the right legal documents built in. Manage your cap table and handle SEIS and EIS in the same place.
Advance Subscription Agreement (ASA)
Take investment now and convert it into shares at your next priced round. No valuation needed yet, no interest and no repayment, which is what keeps it SEIS and EIS eligible.
Priced Equity Round
Agree a valuation and issue shares to investors straight away. The standard route for seed and Series A rounds, with every document generated for you and Companies House ready. SEIS and EIS friendly.
Rolling Round
Open your round once and let investors join over time on the same terms, closing in stages as commitments come in. Keeps momentum without starting a new process each time. SEIS and EIS friendly.
Compliant and secure,
by default
Built around UK venture standards, tax rules and security, so every raise starts on solid ground.
Your funding round
step by step
From your first cheque to close, here is how a funding round works on Undo.
Everything generated
filed and stored for you

SHA, Articles, Disclosure Letter, Board and Shareholder Resolutions, SH01 and Share Certificates. Auto-generated, filled from your round and ready to file with Companies House.
As soon as you set your round type, valuation and investor terms, your term sheet is drafted and filled in for you. Review it, change any clause, and it stays in sync with the rest of your document pack.
Your Shareholders Agreement, Articles of Association, Disclosure Letter and resolutions are generated from your round details and BVCA model templates, so they are consistent and ready for investors to e-sign.
Every document sits in draft until you are ready. Preview the full pack, share it with your lawyer for a second pair of eyes, and only then launch the round to investors.
Undo sends your allotment to Companies House and HMRC, keeps your statutory registers current, and updates your cap table as shares are issued.
When you allot shares, Undo prepares your SH01 return of allotment and files it with Companies House within the statutory deadline, so you never miss it.
Your statutory registers, including the register of members and the PSC (people with significant control) register, update automatically as shares are issued and ownership changes.
Every allotment writes straight to your cap table, so ownership, dilution and option pool figures are always current, with no spreadsheets to reconcile.

Every term is yours to set
with sensible defaults
Full flexibility on the terms that matter, but defaults are pre-set so you do not need to be a lawyer.

Have a question?
We have answers.
What types of funding round can I run on Undo?
You can run a priced equity round, an Advance Subscription Agreement (ASA), or a rolling round that stays open as investors commit over time. Undo loads the right documents for whichever you choose.
Are the documents SEIS and EIS compatible?
Yes. Priced rounds and ASAs are structured to meet HMRC rules so your investors can keep their SEIS and EIS relief. Convertible loans are the exception, as debt does not qualify for SEIS or EIS.
Do you file with Companies House and HMRC for me?
Undo prepares and files your SH01 return of allotment with Companies House, and helps you handle the SEIS and EIS compliance steps with HMRC. Your statutory registers are kept up to date automatically.
Can my lawyer or existing investors review the documents before signing?
Yes. Every document stays in draft until you launch. You can share the full pack for review and add comments before anything is sent for signature.
How does my cap table stay up to date?
Your cap table is built in. As shares are allotted and the round closes, ownership, dilution and your option pool update automatically, so it always reflects reality.
Can I customise the terms, or are they fixed?
Every material term is yours to set, from valuation and option pool to liquidation preference and vesting. Sensible defaults are pre-set so you do not need to be a lawyer, but you can change any of them.
Do you support international investors?
Yes. Undo supports UK companies raising from both UK and international investors, with multi-currency commitments and the right documents for each.
What does it cost to run a round?
Pricing depends on the plan you choose. See the pricing section for the current tiers, or book a demo and we will walk you through the option that fits your round.
