Extreme Filer is led by Ahmed Ali, a US/UK formation and tax compliance specialist. Before founding Extreme Filer, he headed a company formation department that processed 40–50 EIN and 10–15 ITIN applications every month for non-US founders — real filings, real IRS correspondence, real deadlines.
That experience is now focused on the people big filing websites underserve: non-resident founders, Amazon and Shopify sellers, SaaS builders and freelancers who need a US or UK company to sell and get paid globally — and a specialist who answers on WhatsApp when something comes up.
