Before his tenure at Lending Club, he also co-founded and led TripleHop Technologies, the maker of the MatchPoint software, which was subsequently acquired by Oracle Corporation.

[6] In New York, Laplanche soon left the law offices and, in 1999, jco-founded a software company named TripleHop Technologies with Franck Nazikian.

[13] MatchPoint was adopted by many U.S. media companies (CNN, Turner Broadcasting, AOL, USA Today, ABC news, Dow Jones, New York Times and others) as their preferred search engine and attracted the attention of major software vendors.

Laplanche had gotten the idea for the new company at the time when he started TripleHop and found that his credit card carried an 18% interest rate, while he was only earning 1.5% from the bank on high yield certificates of deposit.

[8] In 2010, after receiving $12 million in funding from venture capital investors, Laplanche developed LendingClub into a full-scale person-to-person lending company.

[26] In November 2021, Upgrade grew 83% in valuation over four months to $6.28 billion after raising $280 million in a Series F funding round led by Coatue Management and DST Global.

[31][32] Between April 1 and September 22, 2015, Laplanche and the crew of the Lending Club 2, a 105-ft maxi-trimaran, held the speed record for sailing from Cowes to Dinard across the English Channel.

[33][34] Between July 15, 2015, and May 17, 2017, Laplanche also held the Transpac record between Long Beach, CA and the Diamond Head lighthouse in Oahu, Hawaii in 3 days, 8 hours, and 9 seconds.
