Flex AI Startup Raises $60M to Deliver Tailored Finance Tools for Mid-Sized Businesses

Flex, an AI-driven fintech startup, has raised $60 million in a new funding round to accelerate development of its specialized financial tools targeting mid-sized businesses, reflecting robust investor enthusiasm for AI solutions addressing underserved enterprise segments. The capital infusion, led by prominent venture firms, will fuel platform enhancements in automated accounts receivable, dynamic financing, and predictive cash flow analytics, enabling companies with $10-500 million in revenue to optimize working capital without traditional banking hurdles.

The platform leverages generative AI to automate invoice processing, predict payment delays, and offer instant credit lines based on real-time data, reducing days sales outstanding by up to 40% for users in manufacturing, logistics, and services. This focus on mid-market gaps—where legacy ERP systems falter and enterprise tools prove too costly—positions Flex to capture a $100 billion opportunity in B2B payments and finance automation.

Investor confidence stems from Flex's proven traction, with thousands of mid-sized clients reporting 25-30% improvements in liquidity metrics amid economic volatility. The funding underscores a broader trend where AI fintechs are reshaping finance for non-enterprise segments, competing with incumbents like QuickBooks and challenging banks' dominance in SMB lending.
