Ad Optimization Startup Boost Media Raises $19M More

Boost Media announced earlier today that it has raised $19 million in Series C funding.

The company allows advertisers to find the best version of their search ad — it tests variants created by a network of freelance copywriters and designers, identifies the versions with the most clicks or highest conversion rates, then promotes them in a broader campaign.

I last covered the company about a year ago, under its old name BoostCTR, when it raised an $8 million Series B. At the time, CEO David Greenbaum said that he was planning to shift his focus from small and medium businesses to enterprise customers. He told me last week that the strategy has paid off, with more than 100 large brands using the platform.

“Enterprise advertisers feel that pain more acutely,” he said, later adding, “So in this enterprise use case, I hve 10 thousand, 100 thousand, 1 million skews that I’m selling — how do I be sure that I have the most persuasive monthly marketing spend?”

Greenbaum also said that he’s interested in moving into display advertising eventually, but right now the opportunity in search is big enough that he wants to “double down” there.

Boost has now raised a total of $31 million. The new round was led by Battery Ventures, with Battery’s Roger Lee joining the board of directors. Previous backers Javelin Venture Partners, Pinnacle Ventures, and Webb Investment Network also invested in the new funding.
