PebblePost, a startup pioneering programmatic direct mail, said Tuesday it had secured a $25 million Series C funding round to integrate with the existing programmatic ecosystem.
The new investment was led by Advance Venture Partners and brings PebblePost’s total funding to almost $50 million.

PebblePost works by retargeting online browsers with direct mail offers, so someone who clicked through a retailer’s product pages could get a pamphlet offering deals on those items.

The company has a data onboarding service to match online identifiers like cookies and mobile device IDs to its archive of home addresses, which is augmented by data from companies like LiveRamp and Experian.
