Upstream Festival 2026 adds side events and full founder program

By AI, Created 9:40 AM UTC, May 20, 2026, /AGP/ – Upstream Festival has released the full program for its May 21, 2026 edition in Rotterdam, along with 25-plus side events across the city during festival week. The lineup is built around founders and investors, with workshops, matchmaking, investor breakfasts and sector tracks in Port & Maritime, Health & Wellbeing, and Climate & Energy.

Why it matters: - Upstream Festival is trying to make its 2026 edition more useful for founders and investors by emphasizing practical meetings, smaller-format sessions and curated introductions. - The festival’s wider region-wide programming extends networking and dealmaking beyond a single day in Rotterdam. - The event keeps a strong focus on startup capital, growth support and sector-specific connections.

What happened: - Upstream Festival unveiled the full program for its 2026 edition and published the side-events schedule for Rotterdam during Upstream week. - The main festival day takes place May 21, 2026, at the Van Nelle Fabriek in Rotterdam. - The festival is designed for founders, investors and ecosystem builders from across Europe. - The program is built around more workshops, fewer stages, curated matchmaking, Startup Roulette and dedicated founder spaces. - The full program and side events are available on the Upstream Festival website.

The details: - The Main Stage will feature stories from founders and operators who have built, scaled, pivoted, raised and grown companies across sectors and stages. - The Startup Stage will host the NL Startup Competition finals for the third year in a row, in partnership with Draper University. - The Funding Hub will cover fundraising, while the Growth Hub will focus on early sales, team building, storytelling and long-term growth. - Startup Roulette will offer curated 20-minute speed-dating meetings between startups, scale-ups, angel investors and venture capital firms. - A founders-only lounge will add another dedicated space for in-person founder interaction. - Featured speakers include Barbara Barend of HERA United, Matthijs Welle of Mews, investor Vicky Kuang of Draper Associates, Siete Hamminga of Robin Radar Systems and Constantijn van Oranje of Techleap. - The side events are being organized by Upstream’s co-creation partners and are designed to add focused sessions, informal networking and smaller curated gatherings. - The side-event lineup spans more than 25 events across the region, including CEO dinners, networking moments, sportive activities and informative sessions. - Founder-focused events include Scaling on the Green, Scaling with Diverse Talents, Founders’ Speakeasy: Cocktails, Confessions, Liberations & Libations, Conquering Regulated Markets: Unlocking True Customer Value While Meeting Regulations and the Funded Founders Breakfast. - If the Funded Founders Breakfast is not publicly available, the release says organizers can substitute Ultimate Website Roast: Why Your Startup Website Doesn’t Convert. - Investor-focused events include the VNTR Investor Breakfast, VC Investor Breakfast and The 14th Builders Investor House.

Between the lines: - Upstream is positioning the festival less as a stage-heavy conference and more as a working session for startup relationships and outcomes. - The mix of founder stories, investor meetings and intimate side events suggests the festival wants to accelerate deals and partnerships, not just conversations. - The extra focus on Port & Maritime, Health & Wellbeing, and Climate & Energy points to a sector strategy while still keeping the event open to broader innovation. - The co-founders say the goal is to create more ways for founders and investors to meet with real intent and to turn useful conversations into company progress.

What’s next: - More speaker and session updates will be added before the festival. - Participants can register and buy tickets through the festival website. - The side events will unfold across Rotterdam during the week of May 18, 2026.

The bottom line: - Upstream Festival 2026 is betting that curated matchmaking, hands-on workshops and city-wide side events will deliver more value than a traditional conference format.
