“Can a single integrated financial platform replace both legacy bank accounts and fragmented fintech point solutions for SMBs — first in Australia, then globally?”
Founded in 2020 as an Australian EFTPOS/payments challenger for SMEs, Zeller rapidly expanded beyond terminal payments into full business banking — offering transaction accounts, debit Mastercards, savings accounts, and expense management. By 2022 it had crossed $1B valuation and signalled intent to add lending, cementing its position as a business financial OS rather than a single-product payment company. In 2026, it expanded internationally into the UK, marking a significant geographic pivot from its Australia-only roots.
