November: Smart City Expo week

Smart City Expo World Congress · 3–5 November · Barcelona. The smart cities congress organised by Fira de Barcelona. It brings together public administrations, corporations and startups in mobility, energy and urban data. Dates on the official website. If you sell to city councils or large infrastructure companies, this is the week with the most decision-makers per aisle.

Barcelona Deep Tech Summit · 3–5 November · within Smart City Expo. Three days on AI, quantum, semiconductors and biotech, with room for deep tech investment. It takes place within the Smart City Expo World Congress, according to its official website. The most interesting event of the month for deep tech funds and founders.

Tomorrow.Mobility and Barcelona Cybersecurity Congress · 3–5 November · alongside Smart City Expo. Smart City Expo lists them as shared events, together with Tomorrow Blue Economy and HOWS Summit. Tomorrow.Mobility covers urban mobility and Barcelona Cybersecurity Congress gathers security teams, a key topic for any fintech or exchange.

Gartner IT Symposium/Xpo · 9–12 November · Barcelona. Gartner’s event for CIOs and technology leaders. Useful if your customer is a CIO or CTO at a large company. Programme and pricing on Gartner’s website.

DevFest Barcelona · 28 November (to be confirmed). The annual Google developer community conference appears on listings such as dev.events with that date, but the official DevFest FAQ has not yet published the calendar. Check with GDG Barcelona before booking.

December: closing the year

Tech Spirit Barcelona · 2–3 December · Llotja de Mar. The startup, investor and corporate gathering that closes the city’s tech calendar. Dates and venue on the official website. A good moment to restart conversations with funds before the Christmas break and prepare Q1 rounds.

The rest of December fills up with meetups, demo days and community dinners announced at short notice. Follow the agendas of Barcelona Tech City, the accelerators and the city’s crypto and fintech communities.

How to get the most out of these events

• Book meetings before you go. At large congresses, the best conversations are set up weeks earlier by email or LinkedIn.
• Pick one or two events per month. Going to everything dilutes follow-up. Fewer, well-worked contacts are better.
• Use the side events. Dinners, side events and private gatherings around Smart City Expo often generate more business than the aisles.

DEXT FORCE: finance, AI and startups in Barcelona

DEXT FORCE is a Barcelona congress on finance, artificial intelligence and startups that ends with the after party: an electronic music festival on the same day. Talks by day, quality networking and the after party to close the conversations that start on stage.

If you are a brand and want to meet founders, investors and product teams, see the brand meetings programme. Dates for the next edition will be announced on the official website.
