Fundraising
Series B
A growth-stage venture round, typically $15-50M, raised to scale a business that has proven product-market fit and is ready to expand aggressively.
Series B is the growth round — capital for scaling a company that has proven its core business model works. By Series B, investors expect significant revenue (often $5-20M+ ARR for SaaS), demonstrable unit economics, and a clear path to scaling. Use of proceeds: expanding sales and marketing, entering new markets or verticals, and building out the executive team. Check sizes typically range from $15M to $50M+, with valuations of $30M-$200M+. Series B is where companies transition from 'does this work' to 'how big can this get.' Board composition becomes more formal. At Series B, the lead investor relationship matters enormously — you'll work with them for years through the company's most important growth phase.
