Oliver Jung
About Oliver Jung
Oliver Jung is a German entrepreneur and angel investor. Lounge lists him in London, and some directory bios also place him in Tel Aviv. A Wikipedia entry says he was born in 1972 and studied computer science at the University of Karlsruhe.
He founded the eCommerce consulting firm Entory AG in 1997. Wikipedia reports that Deutsche Boerse Group bought it in 2001, when it had around 100 million euros in annual sales. He then stayed on the executive board of Deutsche Börse Systems AG for a year. From 2003 he began investing in early-stage internet and mobile companies.
PitchBook describes him as a co-founder of Springstar and says he previously owned and served as managing partner of LAO Ventures. It also lists earlier roles as managing partner at Miropolski and investment manager at Adinvest. Nordic9 says he makes private investments through LAO Holdings. Investor directories list Airbnb, Houzz and HotelTonight among his earlier projects. Crunchbase records 0 companies founded under the profile Lounge uses.
Note: the website oliver-jung.de, listed in some data sets, belongs to an unrelated plumbing and heating business. Lounge does not treat it as this investor's site.
Crunchbase shows 16 investments on the profile Lounge tracks, with 0 lead investments and 0 exits. Other trackers count more deals, because they define investments and coverage differently. PitchBook lists 80 investments and CB Insights lists 43. Founders should treat all of these counts as approximate.
His recent deals are mostly seed, pre-seed and Series A rounds. The latest on record is Corgi's Series B, announced in May 2026, which follows his participation in its Series A in January 2026. Public round announcements usually name him in a list of angels or participating investors, not as the lead.
Crunchbase counts 11 AI investments since 2023. The AI portfolio includes Corgi Insurance, Artisan AI, Confident AI, Circleback, Tzafon and Kontigo.
The dated rounds below come from company announcements and investor databases. Circleback's $2.5M seed round, announced in November 2024, named him among its angel investors. NFX Signal lists Confident AI's seed round in March 2025. Tzafon's pre-seed round, announced in July 2025, was led by HV Capital and also included him. Corgi announced its $108M Series A in January 2026 and listed him among its investors.
Wikipedia's Artisan AI article describes a seed round led by him. Crunchbase shows no lead investments for him, so the lead role in that round is not confirmed elsewhere.
Investor databases list pre-seed, seed and Series A as his usual entry stages. They also show him returning for later rounds, as with Corgi's Series B. Crunchbase and PitchBook classify his recent companies as AI, business and productivity software, financial software and insurance technology.
Geographically, his recent deals include companies in the United States (Corgi, Circleback), Sweden (Tzafon) and the United Kingdom. Some directory bios say he works with US and China-based companies on international expansion.
His check size is not public, so this page does not give one. Round sizes in databases are the totals raised by the company and do not show his own cheque. He has not published a thesis or a list of what he looks for.
