Why we're doing this
Early members helped us build this.
We want to reward that.
We're still in private beta. The people who join now are taking a small leap of faith — and in return, we're giving them deals that will never exist once we launch publicly. The 36-month deal means we make less money per user in the short term. That's fine. We'd rather have happy founding members than slightly more revenue from people who never felt they got a great deal.

What you're joining
UK crypto tax in plain English. Free to see your gain.
Most crypto tax tools charge you before they show you anything. You do not know if you owe £0 or £5,000 — and to find out, you are expected to pay first. That is backwards.
Polyconomic shows you your taxable gain for free. If you owe nothing, you pay nothing. If you need the official SA108 report to file your Self Assessment, the Standard plan is £49 a year.
