2027 Startup Event Calendar: Every Major Conference in One Place

The 2027 startup event calendar — every major conference, tech week, and demo day season by month and city, so you can budget and plan the year now.

If you plan to raise, hire, or land customers at events in 2027, you need the calendar before the year starts — not after early-bird pricing closes. This page puts every major startup and tech conference in one place: confirmed dates, cities, and who each event is actually for, followed by the budget and strategy notes that turn a calendar into pipeline.

We verified every confirmed date against the organizer's own announcement (last checked October 31, 2026), and we mark events TBA where 2027 dates haven't been published yet. Bookmark this page — we update it as organizers lock in their dates.

What are the biggest startup events in 2027?

The anchor events of the 2027 founder calendar are CES (January 6–9, Las Vegas), MWC Barcelona (March 1–4), NVIDIA GTC (March 15–18, San Jose), SXSW (March 15–21, Austin), SaaStr AI Annual (May 11–12, SF Bay Area), Web Summit Vancouver (May 25–28), LA Tech Week (September 13–19), Dreamforce (September 21–23, San Francisco), SF Tech Week (October 4–10), and Money20/20 USA (October 19–21, Las Vegas). On top of those, a16z runs four Tech Weeks in 2027: Boston (April 26–May 2), New York (June 7–13), Los Angeles (September 13–19), and San Francisco (October 4–10).

For most founders, that's already more big-ticket events than any one company should attend. The realistic play is one anchor conference per quarter, the Tech Week in your own (or your customers') city, and a steady drumbeat of local events in between. The month-by-month breakdown below is built for exactly that.

The 2027 startup conference calendar, month by month

Here's the full 2027 calendar, month by month. Confirmed dates are listed as announced; events without published 2027 dates are marked TBA with their usual window so you can hold the month.

January 2027

CES — January 6–9, Las Vegas. The year's first mega-event. For founders, CES is a hardware and consumer-tech showcase — worth it if you're launching a physical product, selling into consumer tech, or doing partner development. Everyone else can follow the announcements from home and save the travel budget for March. January is otherwise quiet: local meetups ramp back up in the second half of the month, which makes it the best month of the year to plan the rest of your calendar while rooms are empty.

February 2027

No mega-conference owns February, which makes it prime time for founder-heavy niche events — ETHDenver typically anchors the month for crypto and AI builders (see our ETHDenver founder's guide), and regional ecosystems run their biggest winter events before conference season eats everyone's calendars. Use February for local rooms: they're small, warm, and full of founders who stayed home.

March 2027 — the heaviest month of the year

MWC Barcelona — March 1–4 (with 4YFN, its startup-focused sibling, running alongside). NVIDIA GTC — March 15–18, San Jose. SXSW — March 15–21, Austin (Innovation tracks run March 15–20). March is the single most concentrated month in tech, and most founders can only pick one. GTC is the must-attend if you're building on or around AI infrastructure — the whole AI supply chain is in one building, and startup programs like NVIDIA Inception bring the cost down (our guide to AI events for founders covers how). SXSW is the better pick if you're at the intersection of tech and culture, media, or consumer. Accelerator winter-batch demo days also cluster in late March — check our demo day and funding events guide for how to get into them as a non-pitching founder.

April 2027

Tech Week Boston — April 26–May 2. The a16z Tech Weeks are the best-density events of the year for founders: mostly free, ecosystem-wide, and packed into a single city. If you're in or selling into the Boston biotech and deep-tech corridor, this is your week. April is otherwise a shoulder month — spring demo nights and university entrepreneurship events fill the calendar across most cities.

May 2027

SaaStr AI Annual — May 11–12, SF Bay Area. The biggest B2B SaaS founder event repositions around AI in 2027; if you sell to SaaS companies, your buyers are in that room. Web Summit Vancouver — May 25–28. The largest conference in North America now happens in Vancouver, and it's a genuinely useful one for founders — the startup program, side events, and investor presence are strong (see our Web Summit review for early-stage founders). May closes the first half's big-event run, which makes late May the right time to review what your Q1–Q2 events actually produced.

June 2027

Tech Week New York City — June 7–13. NYC Tech Week is the largest of the four Tech Weeks — hundreds of events across fintech, commerce, media, and enterprise software, most of them free. If New York is your market, block the week now; the good events fill fast. June also kicks off summer demo day season for accelerator summer batches.

July and August 2027

The mega-conferences go quiet, and the calendar belongs to local ecosystems: Seattle Tech Week typically lands in mid-July (2027 dates TBA), and city-level meetups, BBQs, and demo nights keep relationships warm while everyone's travel budget recovers. Treat July–August as your low-cost, high-touch months — and the time to book Q4 trips before hotel rates spike. If you're raising, summer demo days (usually mid-August, TBA) are worth watching even if you're not pitching.

September 2027

Tech Week Los Angeles — September 13–19. The creator, consumer, and media-tech week. Dreamforce — September 21–23, San Francisco. If you sell anywhere near the Salesforce ecosystem, it's the densest buyer concentration of the year. Denver Startup Week — one of the best free founder conferences anywhere — typically runs late September or early October (2027 dates TBA), and MicroConf, the bootstrapped-SaaS founder favorite, has historically landed in September too (TBA). September is also when accelerator summer-batch demo days finish, so the investor crowd is out and about.

October 2027

Tech Week San Francisco — October 4–10. The biggest AI-week of the year in the AI capital; if you attend one Tech Week, this is it. Money20/20 USA — October 19–21, Las Vegas (new home at the Las Vegas Convention Center and Resorts World) — the fintech and payments event where deals actually close. GITEX Global in Dubai typically runs mid-October (TBA) and is worth a look if you're expanding into EMEA or the Gulf. TechCrunch Disrupt, historically an early-October SF staple, has not announced 2027 dates — mark the window and check before booking.

November 2027

The European stretch: Slush in Helsinki — the most founder-friendly investor event in Europe — typically runs mid-November (2027 dates TBA), and Web Summit in Lisbon has historically anchored early November (TBA). For US founders raising from European funds, November travel is the highest-ROI trip of the year. Slush's format deliberately inverts the usual dynamics: investors apply to meet founders, not the other way around.

December 2027

AWS re:Invent — typically late November–early December, Las Vegas (2027 dates TBA). The cloud and AI-infrastructure community's closing week. December itself is otherwise year-end territory: holiday networking, small dinners, and the reconnections that set up January's intros. Our winter 2026–27 startup calendar covers the December–February rooms in detail.

How much should a founder budget for conferences in 2027?

Plan on $1,500–$4,000 all-in per out-of-town conference — ticket, flights, hotel, and meals — and roughly $0–$50 for Tech Week and local events, most of which are free. A realistic annual budget for an early-stage founder is two anchor conferences ($3,000–$8,000 total), one Tech Week in your own city (free), and monthly local events (~$500/year). The full breakdown — including what drives the price of each line item and where founders overspend — is in our 2027 conference budget guide, and the ways to cut ticket costs (startup programs, volunteer badges, community codes) are covered in how founders get discounted conference tickets.

How do you choose which 2027 conferences are actually worth it?

Pick events by who's in the room, not by how famous the name is. The filter we recommend: one event per quarter, chosen by where your next five customers, hires, or investors spend their time — then fill the gaps with free local rooms, which convert better per hour than any badge. We walk through the full decision framework (including when to skip a big conference entirely) in how to choose which startup events to attend, and the quarter-by-quarter rhythm is laid out in the founder's guide to conference season. For vertical picks — SaaS, fintech, healthtech, AI, and more — our event guides by topic are linked below.

When are demo days and pitch competitions in 2027?

Demo day season clusters twice: late March (winter accelerator batches) and August–September (summer batches), with university pitch competitions stacked in April and November. You don't need to pitch to benefit — demo days are open to spectators more often than founders expect, and they're one of the fastest ways to meet a room full of active investors at once. Start with the demo day and pitch competition guide for the format, and our funding events roundup for which ones are worth the time.

Fill the gaps with local events

The 2027 calendar above is the skeleton; the muscle is the weekly local layer — meetups, demo nights, and founder dinners that cost nothing and compound every month. That's what 47Hz tracks: every startup event in your city, in one Monday-morning digest. Browse live events →
