OCTA has raised a $3.5 million seed round led by MEVP as it unveils OCTA Flow, a suite of AI agents designed to perform bookkeeping, reconciliations and month-end close tasks for accounting firms before handing work back to accountants for review and approval. The round brings the startup’s total funding to $5.7 million.
OCTA launches OCTA Flow, an AI agent suite for accounting firms
OCTA Flow is intended to move beyond automating individual finance processes — such as invoicing or collections — to completing portions of recurring accounting workloads autonomously while leaving final professional responsibility with the accountant. More than 520 firms have signed up for access in the six weeks since the product’s launch, the company says.
The company reports its platform processed 172,000 transactions without manual handling in August, which it estimates freed up more than $75,000 in billable capacity for accounting firms.
Funding, founders and geographic expansion
The $3.5 million seed was led by MEVP, with participation from Wa’ed Ventures, Plug and Play and A-typical Ventures, alongside existing investors Sukna Ventures and Sadu Capital. OCTA previously raised a $2.25 million pre-seed round in October 2024 co-led by Quona Capital and Sadu Capital, with participation from Sukna Ventures, Plus VC and 500 Global. Last June, OCTA also secured a separate $20 million credit facility from Saudi’s Sukna Fund for Direct Financing to offer short-term working capital through its invoicing and payments platform.
Founded in 2024 by Jon Santillan and Nupur Mittal, OCTA initially focused on automating accounts receivable and accounts payable for SMEs, including invoicing, payments and collections. Santillan previously co-founded money-transfer infrastructure company Denarii, whose assets were acquired by Careem in 2022; he then joined Careem and worked on its remittances business. Mittal came from Careem Pay, where she worked across product and strategy, after an earlier role at BCG.
OCTA began in Saudi Arabia and the UAE, markets where corporate tax, e-invoicing and other regulatory changes have increased structured finance and accounting work. It has since expanded into the US, targeting firms that want to take on more clients without increasing headcount at the same pace.
