Why trust us
Built by the founder of the first SEIS fund on the market in 2012. Someone who has sat on all sides of the table: as the fund deploying investment, as the adviser helping founders get investor ready, and as a founder raising himself. Someone who has never, not even once, had an application not sail through first time.
We have been in this world since 2012.We know what HMRC looks for, what trips founders up, and why most straightforward AA cases don't need a full advisory engagement. Seisly is built for those cases. For everything else, as part of GoLitigo we have a network of specialist advisers.

Full advisory engagements make sense when your situation is complex, you need ongoing tax or corporate advice, or you want someone in your corner for the whole raise. For those cases we refer founders to specialist advisers in our network.
