Who We Are REXX Studio is a venture studio that co-founds tech companies for under-digitalized mid-market industries. We engineer every company from Day 0 for Private Equity roll-up buyouts and venture scale. REXX acts as co-founder and first allocator on every company.

You manage the financial architecture that keeps the studio and its spinout ventures operating smoothly. You will oversee multi-entity capital allocations, financial modeling, budgeting, LP data rooms, and corporate compliance across Delaware C-Corps and Mexican subsidiaries.

- Track monthly studio burn, cash runway,



and unit economics across parallel builds to maintain strict capital ceilings.

- Accounting, Tax & Automation: Oversee corporate accounting compliance (US and Mexico), inter-company billing, vendor contracts, and set up automated reporting workflows using tools like Excel, Notion, and Zapier for real-time visibility.

1+ years in Corporate Finance, VC Back-Office, Fund Operations, or Startup FinOps (experience in a Venture Studio, VC fund, or venture-backed company is a major plus).
