Blackbaud Inc. is buying JustGiving, a London company whose website lets people raise money for charities and for one another.

The Daniel Island software company said Monday that it agreed to acquire JustGiving for 95 million British pounds in cash, subject to adjustments. The two sides signed the deal Friday, according to a filing Blackbaud made with federal securities regulators.

Blackbaud plans to pay with cash on hand and borrowings under its existing credit facility. The deal needs approval from the Competition and Markets Authority, the U.K. competition regulator, and is expected to close later this year, the company said.

The buyer is Blackbaud Global Ltd., Blackbaud’s U.K. subsidiary, which is purchasing all the shares of Giving Ltd., the company that operates JustGiving, according to the filing.

What JustGiving does

JustGiving is a leader in what the charity sector calls peer-to-peer fundraising, in which individual supporters rally others in their networks to give. It also offers personal crowdfunding, in which individuals raise money for other individuals.

Since it launched in 2001, JustGiving has enabled more than 22 million people to raise more than $4.5 billion for more than 26,000 charities, according to Blackbaud’s announcement. People in 164 countries have raised money through it.

Blackbaud already sells two peer-to-peer fundraising tools, TeamRaiser and everydayhero, which nonprofits use to connect their causes with individual supporters. JustGiving will expand those offerings, the company said, and add a personal crowdfunding product that Blackbaud can roll out in the United States and elsewhere.

Why Blackbaud wants it

Blackbaud said giving through social media and mobile phones keeps growing, and individual supporters rallying their own networks play a significant and growing role in charitable giving.

“As a software leader exclusively focused on innovation that drives social good, it’s in our DNA to respond to and anticipate changes in the way people give and connect with causes,” Blackbaud President and CEO Mike Gianoni said in the announcement.

Gianoni said JustGiving’s crowdfunding expertise, combined with Blackbaud’s cloud software and customer base, would “forge deeper and more effective connections between people and the causes they support.”

Jerry Needel, president and general manager of Blackbaud Consumer Solutions, said donors want to give “on their own terms.”

“Bringing JustGiving into the Blackbaud family reinforces our strong commitment to catalyzing the impact of individual change agents,” Needel said.

The company said the deal will also position it to better serve the United Kingdom, where Blackbaud has operated for more than two decades and where JustGiving is a fundraising leader.

What JustGiving says

Anne-Marie Huby, JustGiving’s co-founder and managing director, said the way people give is changing quickly.

“Social, mobile and the rise of crowdfunding combined are transforming the way people give, and the pace of change is unprecedented,” Huby said in the announcement. She said joining Blackbaud would help “great causes reach more people and raise more money, more effectively and intelligently than ever before.”

JustGiving’s staff is expected to move to Blackbaud once the regulatory review is finished. They will become part of Blackbaud’s London-based International Markets Group, led by Jerome Moisan, a senior vice president and president of that group. The companies will settle on a full integration plan after the deal closes, Blackbaud said.

The buyer

Blackbaud reported revenue of $730.8 million for 2016, up from $637.9 million the year before, according to its annual report. It had 3,156 employees at the end of 2016.

The company calls itself the world’s largest cloud software company powering nonprofits and other social good organizations. It serves nonprofits, foundations, corporations, education institutions and individuals, and it has operations in the United States, Australia, Canada and the United Kingdom.

In 2015, Blackbaud bought Smart Tuition, a New Jersey company that provides payment software and services for private schools and parents, for an aggregate purchase price of $190 million, according to the company.
