Advent International, a global private equity investor, have led an investment round in Assembly, a eCommerce software and data company. PSG, a growth equity firm partnering with middle-market software and technology-enabled services companies, also participated in the round.

“What aggregators have done for brands, we have been doing for software,” says Sandeep Kella, co-founder and CEO of Assembly. “We are singularly focused on helping eCommerce merchants grow better by bringing together software tools and combining them with valuable content. Our mission is to meet our customers’ needs at every stage of their growth.”

“There are millions of eCommerce merchants globally that need world-class software to operate more profitably in an increasingly complex multi-channel world,” said Eric Wei, a managing director on Advent’s technology team in Palo Alto. “Assembly is a clear SaaS leader in terms of market intelligence data, user community, and merchant relationships. With Advent’s capital, we believe Assembly will become the industry platform to enable all merchants to thrive.”

“We’re incredibly proud of the growth the Assembly team has achieved to date and the exciting path the company is on as it aims to serve as a one-stop-shop for e-commerce merchants,” said Matt Stone, managing director at PSG. “We thank Sandeep and the entire Assembly team for their dedication and hard work, and we’re excited to continue our partnership to support the next phase of Assembly’s evolution.”
