Quick Answer
California hosts the largest technology conference in the world, the most influential finance gathering on the West Coast, two of the biggest trade shows in the country and dozens of founder events. That is a lot of options and a lot of money. This list ranks the ten we think are worth a founder's time in 2027, with the dates, scale and price you need to compare them.
Two notes before the list. Traffic and Conversion Summit has been cancelled, so you can cross it off. And Fortune Brainstorm Tech is held in Aspen, Colorado, not California, despite what some listings say. Every remaining date was checked on October 15, 2026.
How did we rank them?
We scored each event on five things a business owner cares about: access to peers at your level, access to speakers, total cost, likely outcomes (deals, capital, hires) and fit for a founder rather than an employee. A big event can score well on speakers and poorly on peer access. A small one can be the reverse. The ranking is our view, and we disclose that we organize number ten.
How do the top 10 compare on size and price?
| Rank | Event | City | 2027 dates | Attendance | Ticket |

| 1 | Dreamforce | San Francisco | September 21 to 23 | 50,000 plus in person (2026) | About $2,299 full pass (2026) |
| 2 | Milken Institute Global Conference | Beverly Hills (2026 venue; 2027 city not yet listed) | May 2 to 5 | Thousands of participants | Invitation and member based |

What does each conference give a founder?
1. Dreamforce, San Francisco, September 21 to 23
Dreamforce is Salesforce's annual event at the Moscone Center and the largest software conference in the world. Salesforce reported more than 50,000 in person attendees in 2026. Third party guides listed the 2026 full pass at about $2,299; Salesforce says 2027 registration opens in spring 2027. It is best for founders in software, sales and customer operations who want to see where the enterprise market is going. Peer access for a small business owner is low because of the sheer size.
2. Milken Institute Global Conference, Beverly Hills, May 2 to 5
The Milken Institute gathers thousands of participants from finance, policy and business. The 2026 edition was held at the Beverly Hilton and the Waldorf Astoria in Beverly Hills; the 2027 dates are confirmed but the venue was not yet listed when we checked. Attendance is largely by invitation and membership. If you raise institutional capital or sell to large enterprises, the room is unmatched. If you run a company with 20 employees, it is hard to get in and harder to be heard.
3. TechCrunch Disrupt, San Francisco, October
TechCrunch Disrupt draws thousands of founders and investors, with Startup Battlefield as the centerpiece. The 2026 edition ran October 13 to 15 at Moscone West; 2027 dates were not announced when we checked. It is the best California event for an early stage tech founder looking for investors and press.
4. Natural Products Expo West, Anaheim, March 2 to 5
The largest natural and organic products show in the country, with more than 66,000 attendees and 3,200 exhibitors. If you make a consumer product, retailers and distributors are here. See our Anaheim guide for the hotel situation that week.
5. The NAMM Show, Anaheim, January 26 to 30
The music products industry's main trade show, with more than 60,000 attendees in 2026. Trade only, and essential if you are in that industry.
6. Google I/O, Mountain View, May
Google I/O is a developer conference, not a business conference, but founders building on AI and mobile platforms watch it closely. In person attendance is limited; the keynotes are free online. The 2026 dates were May 19 to 20; 2027 had not been announced.
7. Social Media Marketing World, Anaheim, April 1 to 3
A practical marketing conference held in Anaheim, with All Access, Marketer and Virtual ticket tiers. For an owner who runs their own marketing, the sessions are directly usable the following Monday.
8. Upfront Summit, Los Angeles
Upfront Ventures, a Los Angeles venture firm, runs an invitation only summit for founders and investors. If you can get an invitation, it is one of the best investor rooms in the state. The 2027 date had not been announced.
9. Small Business Expo, San Francisco, San Diego and Los Angeles
Free one day expos with workshops and exhibitor halls: San Francisco on June 23, San Diego on September 10 and Los Angeles on October 28, 2027 (Pasadena Convention Center). Good for a new owner who wants vendors, SBA resources and local contacts in one morning.
10. AMCOB LEAD Summit, Anaheim, June 11 to 13
Three days, 300 seats, founders and CEOs only, organized by AMCOB, the Allied Muslim Chamber of Business. It is the only Muslim business summit on this list, and the room is Muslim founders, CEOs and owners. Twelve sessions from Friday 5:00 PM to Sunday 2:00 PM. Early bird full summit tickets are $750. It is the smallest event on this list by far, and that is the point: in a 300 person room over three days you can meet most of the other owners, and if you are a Muslim founder in California, nobody in that room needs halal capital, zakat or Ramadan scheduling explained to them. We organize it, so read the honest comparison in small conferences versus large conferences before you decide. Full details are in what the LEAD Summit is.
Which conference should a founder pick?
| Your goal in 2027 | Best pick | Second pick |
|---|---|---|
| Raise venture capital | TechCrunch Disrupt | Upfront Summit |
| Sell to enterprises | Dreamforce | Milken Global Conference |
| Get into retail | Expo West | Small Business Expo |
| Improve your own marketing | Social Media Marketing World | Dreamforce |
| Meet other owners at your level | LEAD Summit | Small Business Expo |
| Muslim founder looking for faith aligned partners and halal capital | LEAD Summit (the only Muslim business summit in California) | See our Muslim business conference guide |
The big events give you reach. The small one gives you depth. Most founders need one of each in a year. If June in Anaheim fits, tickets are here, and our Orange County guide shows what else is nearby.
Full summit tickets for LEAD are $750 at the current early bird rate, and full refunds are available until April 1, 2027. Reserve a seat
