E-commerce florist BloomThat Inc. has raised $5.5 million in Series A funding led by Forerunner Ventures, according to co-founder and President Matthew Schwab. Also joining the round were Sherpa Ventures, Rothenberg Ventures and the company’s earlier seed investors First Round Capital and Vaizra Investments. BloomThat made a name for itself, in part, by delivering bouquets “on-demand,” or within 90 minutes, to recipients in the San Francisco Bay Area. But these days, the startup also allows users to send high-quality bouquets or living plants to recipients at a convenient time designated by the sender, on the same or the next day throughout California. “Not everyone is as bad at planning as I am,” said Mr. Schwab, who still sends the majority of bouquets he buys from his own company using the on-demand option.
