Vestd is where you manage equity: cap table, share options, EMI and other schemes, growth shares, company valuations and Companies House filings. Advance assurance sits inside its InVestd Raise fundraising add-on, because a company raising will usually need it. Seisly does advance assurance, and is building outward from it.
Vestd is a serious, well-run business, and this is a comparison of two different products, not a criticism of theirs. Vestd Ltd is directly authorised and regulated by the FCA (FRN 685992), a certified B Corp and ISO 27001 certified. If you are choosing an equity platform, they are a strong option.
If advance assurance is what you need right now, the number is £99 against £1,750 a year. Vestd has no standalone advance assurance price: the cheapest route is Essentials at £250 a year plus the InVestd Raise add-on at £1,500 on annual billing, which is Vestd's own headline "fixed fee from just £1,750+VAT".
And there is nothing to commit to. Vestd's minimum term is twelve months on every plan, stated in their own FAQ. Seisly is a single payment, with nothing to cancel.
Vestd's advance assurance is customer-only: an existing customer logs in and starts it in-app, and everyone else books a consultation. Every call to action on the advance assurance and pricing pages is Book a call or Meet with Vestd. There is no self-serve purchase path.
That is a reasonable way to sell an equity platform. It is a poor fit for a founder who needs advance assurance this week. Seisly is self-serve, with no account needed for the free eligibility check.
If you are setting up an EMI scheme, managing a cap table with real shareholder activity, need company valuations, or want one platform running your equity for years, Vestd is built for that and Seisly is not.
InVestd Raise at 0% completion fees is genuinely competitive against platforms that take a percentage of the raise. A founder in that position should use Vestd. Seisly is the specialist for the advance assurance step, and you can use both.
No. Vestd includes advance assurance inside its InVestd Raise add-on rather than selling it separately, so the cheapest route is £1,750 a year: Essentials at £250 plus InVestd Raise at £1,500 on annual billing. Seisly prepares advance assurance on its own from £99.
For advance assurance on its own, yes, and by a wide margin: £99, or £399 fully done for you, against £1,750 a year. They are not like-for-like: Vestd's fee runs an equity platform, not one application.
Vestd's minimum term is twelve months on every plan, stated in their own FAQ. Seisly is a single payment, with nothing to cancel.
Vestd, clearly. That is what it is built for, and Seisly does not do share schemes. Seisly is the specialist for the advance assurance step.
Yes. Use Seisly for advance assurance now, and Vestd when you need equity management. They solve different problems, and they sit happily side by side.
Seisly drafts from a short questionnaire, usually under an hour. HMRC then typically takes 4 to 8 weeks, whichever route you use.
