Partner Network
Seisly handles advance assurance as a productised service. We partner with specialist advisers who want the production capability without the build, and who earn on every founder that comes through their funnel.
The situation
Most of the substantive SEIS/EIS content founders actually read comes from smaller specialist firms. Scheme explainers, eligibility guides, qualifying trade analyses. This content ranks, educates the market, and builds the reputation of the firms that write it.
Then readers convert somewhere else. Founders who decide they are comfortable with the scheme head to larger subscription platforms for the filing. Founders who cannot justify a full advisory engagement try to do it themselves, often incorrectly. A smaller group with genuinely complex cases engages the firm directly, but the bulk of the audience is lost before the relationship starts.
Seisly solves this by giving specialist firms a productised conversion path for the readers they are currently losing, and a reliable complex-case flow coming back the other way.
What Seisly does
Seisly is a flat-fee SEIS/EIS advance assurance service built by tax specialists with three decades of experience in the schemes, including running the UK's first SEIS fund in 2012. It's a service of Litigo Limited, a technology company. The Seisly platform handles the full workflow from eligibility check through to HMRC submission pack, with AI-assisted two-pass document review against an HMRC knowledge base and optional human quality control on Express Review.
The scope is deliberate. Seisly handles the straightforward case well and stops there. Group structures, multiple share classes, qualifying trade edge cases, non-UK considerations, prior VCS investment, Knowledge Intensive Company status, and anything requiring genuine adviser judgement all sit outside what Seisly will take on. These cases go to partners.
Seisly also does not touch the three-year compliance window, secondary rounds, or broader advisory work. The partner owns the client relationship and keeps all compliance revenue.
How it works
Seisly's partnership is structured in two layers. Most advisers start with the directory listing, a straightforward way to receive qualified consultation bookings from founders. Firms with a deeper commercial angle can layer on bespoke arrangements beyond the directory.
Advisers who join the Seisly directory appear to founders whose eligibility check surfaces an adviser-relevant case. Founders see matching advisers based on the specific complexity flags in their situation, book a consultation through your Cal.com or similar booking link, and you receive the founder's full eligibility output before the call.
Listing is gated on holding a credit pack, and there are two routes once you are listed. When a founder picks you from the panel and you accept the referral, that costs one credit. You then bill the founder directly, and Seisly takes a 22.5% commission on all fees you bill that founder for twelve months from acceptance.
You can also bring your own clients to the platform. Give a client your Seisly code and they complete the application themselves using Seisly's prompts. Seisly prepares a draft pack only you can access, which appears in your adviser dashboard to download or work on directly. The code route costs four credits per case, whatever the scheme, and carries no commission: you bill the client as you normally would.
Either route, the client relationship is yours throughout. You apply AML and client due diligence through your own process consistent with your regulatory obligations, and the engagement letter is yours.

What Seisly doesn't do
Seisly does not view, access, or retain client or adviser information for any purposes other than operating the platform. We are not in the advisory business: we're the infrastructure that connects founders to the right adviser and processes straightforward advance assurance applications.
Our goal is simple: founders save time and cost by accessing specialist tax and legal advice through the right route, and advisers spend their time giving advice rather than filling forms. We stay out of the advisory relationship entirely.
Beyond the directory, some firms have a stronger commercial angle. Three shapes come up most often.
Co-branded conversion. Firms with existing SEIS/EIS content and organic traffic carry a co-branded Seisly entry point on their site or articles. Readers who would not convert to a full engagement convert to a productised AA instead. The partner earns a revenue share on every case that came through their funnel.
White-label. Firms already doing AA volume can use Seisly as production infrastructure under their own brand. The partner sets the client-facing price and pays Seisly a per-application wholesale fee. Client relationship and all compliance work stays with the partner.
Specialist referral. Firms handling complex cases (group structures, KIC status, non-UK operations, prior VCS investment) receive routed referrals from Seisly on a specialist basis, with fees structured case by case.
These arrangements sit on top of the directory, not instead of it. Most partners who do Layer Two also list in the directory. The terms for Layer Two are discussed per partnership: they depend on your content footprint, volume profile, and where your practice specialises.
What partners get
Revenue without margin pressure. Offer productised AA to clients who can't justify a full engagement, without losing the relationship.
Qualified inbound. Complex cases and ongoing advisory flow back from Seisly, matched to your specialism.
Client ownership stays with you. You remain the named adviser. You own the three-year compliance window. Seisly processes AA and hands the case back.
Transparent attribution. Every partner-sourced application is tracked end to end via a unique partner code. A real-time dashboard shows what your content is earning.
