Controller

Alt is unlocking the value of alternative assets, starting with the $5 B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place and we are backed by leaders at Stripe, Coinbase, Seven Seven Six, and pro athletes like Tom Brady and Giannis Antetokounmpo. Our next frontier is real-time pricing at scale—the Alt Value that powers every trade, loan, and product on the platform. About Us At Alt, we're flipping the script on investing - starting with trading cards. Our mission is to turn alternative assets into investable, liquid markets, and we're already making serious noise in a $60B+ category. Think of us as the modern stock market for culture-backed assets. First stop: trading cards. Next stop: everything else. With over $100M raised from the likes of Alexis Ohanian, founders of Stripe and Coinbase, and top-tier athletes like Tom Brady, Candace Parker, Giannis Antetokounmpo, Alex Morgan, Kevin Durant, and Marlon Humphrey, we're building a platform that powers collectors, investors, and sellers alike. The Role We are hiring a Controller to build and own Alt's accounting function for the first time. Today Finance is a one- person team supported by an outsourced accounting provider — you will bring that function in-house, close out our external audit, lead our conversion to full US GAAP accrual accounting, and take ownership of tax and systems work, reporting directly to the Head of Finance. Alt is fully remote (US), and this is a build-from-scratch role at an early-stage company: you’ll write the policies, checklists, and controls Alt has never had, and grow a small team behind you as volume scales. If you want to own a function end-to-end rather than inherit one, this is that job. What You'll Do • Own the monthly close end-to-end and drive it toward a 5-day, fully reconciled, audit-ready close, with nothing aged past 30 days. • Lead the conversion from mixed cash/accrual to full US GAAP accrual across every revenue stream: auctions, the fixed-price exchange, lending and cash advances, and partner revenue. • Own the chart of accounts and revenue recognition policy, and lead the work to tie GL entries back to our source-of-truth data warehouse (e.g., Snowflake) and feed it directly into QuickBooks or a future ERP, so revenue postings stop being a manual month-end exercise. • Be the primary point of contact for our external auditors: own the PBC list, walkthroughs, and full close-out of open items. • Own the tax compliance calendar (corporate and fund-level returns, K-1s, state and local filings, 1099s, and the annual R&D credit study), working with outside tax advisors. • Own covenant and borrowing-base reporting for our asset-backed credit facility, partnering with the Head of Finance on lender compliance. • Own day-to-day accounting operations (AP/AR, reconciliations, fixed assets, spend controls, and corporate card and vendor administration), and manage our outsourced provider with a mandate to bring the work in-house over time. What You Bring • 8+ years of progressive accounting experience, including hands-on controllership in industry. • Deep US GAAP knowledge, with direct experience converting a company from cash or mixed-basis accounting to full accrual. • Proven ownership of an external audit relationship — PBC lists, walkthroughs, sample testing, and auditor communication. • Experience in a marketplace, fintech, or lending environment, with comfort in principal-vs-agent revenue questions and reserve/receivable accounting. • Fluency with QuickBooks, a modern spend platform (e.g., Ramp), an HRIS (e.g., Rippling), and enough SQL/BI comfort to tie GL entries back to source data, ideally including running an integration between a data warehouse and an accounting system. • Experience managing an outsourced, fractional, or offshore accounting team. • Nice to have: asset-backed lending or covenant/borrowing-base reporting, and experience preparing a company for institutional fundraising or M…
