For a young company preparing a fundraising round in 2027, spring shows remain an effective way to meet investors in just a few days. As of 12 November 2026, seven events for founders scheduled between February and June 2027 have published their official dates, from Nairobi to Helsinki. The dates below are those on the official pages; a final check before buying a ticket is still advisable.
February and March: Nairobi, then Austin
- Africa Tech Summit, Nairobi, 10 and 11 February 2027. The summit dedicated to African tech is held at the Sarit Expo Centre, with four thematic tracks under one roof. Its organiser points to ten years of existence and announces an eleventh London edition in 2027, with no date for now.
- SXSW, Austin, 15 to 21 March 2027. The Texas festival brings together four strands in one week, innovation, film and television, music and comedy, with three conferences and thirteen tracks according to its website. For a start-up, it is the innovation strand that matters.
April and May: Silicon Valley and Canada
- Startup Grind, Redwood City, 27 and 28 April 2027. The conference’s two main days take place at the Fox Theatre, on Broadway, in the heart of Silicon Valley. The website now refers to it as the “Startup Grind Conference”.
- Web Summit Vancouver, 25 to 28 May 2027. The event is held at the Vancouver Convention Centre. Those looking for Collision should look here: the former address of the Toronto show now redirects to the Web Summit Vancouver website, and no 2027 edition of Collision in Toronto is announced there.
June: London, Rio and Helsinki in the same week
- London Tech Week, 7 to 11 June 2027. The exhibition and conference stages occupy Olympia London from 7 to 9 June, while side events are spread across the capital until the 11th. The 2026 edition claimed more than 31,600 attendees and more than 700 speakers.
- Web Summit Rio, 14 to 17 June 2027. The Brazilian event sets up at Riocentro in Rio de Janeiro. The website puts forward more than 40,000 attendees, more than 700 investors and more than 1,500 start-ups, without specifying which edition these figures refer to.
- Arctic15, Helsinki, 16 and 17 June 2027. The Finnish event publishes precise forecasts for 2027: more than 6,500 attendees, more than 750 investors, more than 1,500 start-ups, more than 750 large corporations and research institutes, more than 80 nations and 20,000 meetings. The venue has not yet been specified.
Rio and Helsinki overlap on 16 and 17 June: a small team will have to choose between Latin America and Northern Europe.
Events without a verifiable date yet
Several well-known shows remain up in the air. The website of TNW Conference, in Amsterdam, still shows the June 2025 edition and no 2027 date. For Startup Extreme, in Norway, no 2027 date could be confirmed on the official website as of 12 November 2026. These two events are therefore not dated here.
A practical tip: most of these events offer start-up selection programmes, with stands or investor meetings at reduced rates, whose applications may close well before the doors open. Now is the time to keep an eye on them.
