Boston Tech Week 2026 Opens Tomorrow: a16z Brings 572 Events to Kendall Square

Boston's first-ever Tech Week — 572 individually hosted events spread across eight city neighborhoods — opens tomorrow, Tuesday, May 26, with the official kickoff that evening at 6 p.m., as Andreessen Horowitz formally plants its decentralized conference format in one of the country's most consequential technology ecosystems. The six-day event runs through Sunday, May 31, is free to attend for most sessions, and requires only a per-event registration through the official calendar at tech-week.com/calendar/boston.

For founders, engineers, students, and investors who haven't yet registered: the window is still open. Hosts confirm attendance individually after applicants register through each event's page, and many sessions remain open as of this writing.

The format will be familiar to anyone who attended a16z's Tech Week in New York, San Francisco, or Los Angeles — a sprawling, decentralized series of panels, hackathons, mixers, fireside chats, and pitch competitions hosted by individual companies and organizations rather than through a central convention facility. What distinguishes Boston's edition is the composition of its programming: where New York skews toward fintech and media and San Francisco toward consumer AI, Boston's calendar is dense with biotech, computational biology, robotics, physical AI, and university research — a lineup that maps directly to the region's genuine industrial strengths.

Boston's Ecosystem Earns the Billing

The event lands in a city whose technology credentials are understated relative to their scale. Kendall Square in Cambridge is home to more than 1,000 biotech and pharmaceutical companies within a few square miles, including major R&D operations from Pfizer, Novartis, Sanofi, and Takeda. Massachusetts startups raised $16.7 billion in venture capital in 2025, ranking the state second in the country behind only the San Francisco Bay Area. LabCentral, the shared laboratory infrastructure anchoring the Kendall cluster, has supported 344 companies since 2013, which collectively raised $21.85 billion and created nearly 8,000 life sciences jobs.

Jonathan Lai, a partner at a16z, told the Boston Globe ahead of the event: "I think it's the best time in a decade to start a company in Boston." Boston's mayor welcomed the week publicly, and Sandy Lacey of the Perkins School for the Blind said she hopes it will "bring to light the importance of solving challenges and investing in this space" — a reference to Perkins' DisabilityTech Investor Summit, one of the most distinctive programming elements in the week's calendar.

More than 80 founding hosts are participating, spanning local anchors and national brands: Anthropic, HubSpot, Whoop, Klaviyo, DraftKings, Wayfair, Stripe, IBM, Boston Dynamics, MassRobotics, and The Engine, Built by MIT are all on the calendar alongside a16z itself.

What Opens Tuesday Night and This Week

The official a16z Tech Week kickoff, co-presented by law firm Fenwick and HSBC Innovation Banking, runs from 6 to 9 p.m. Tuesday evening. The opening day also features IBM, the Massachusetts AI Hub, and Red Hat hosting "Ringing in the Inaugural Boston AI Tech Week" in the Seaport District at 9:30 a.m., alongside the UGLY TALK: Boston Tech Founder Open Mic + Mixer at Venture Lane, where founders each get seven minutes to share candid company-building stories.

Wednesday brings one of the week's flagship sessions: "From Models to Medicines: AI Tools Powering Drug Discovery," co-hosted by a16z, MassBio, and Eli Lilly & Company — a direct connection between AI infrastructure investment and pharmaceutical R&D, held in the same city where much of that work actually happens.

Thursday packs the week's densest programming. Anthropic is hosting "Founders' Lab: AI for Life Sciences" at 1:30 p.m. in Downtown Boston, a focused session for companies building at the intersection of AI and medicine. Boston Dynamics is hosting "Celebrating Robotics & Physical AI" at 5:30 p.m. in Back Bay. DraftKings and Whoop are jointly hosting "AI-Enabled Analytics" at 6 p.m. BASE-X's "Future of Dual Use: What's Pacing Human-Out-Of-The-Loop Autonomy?" examines the policy and technical dimensions of autonomous systems.

Friday features some of the week's most unconventional programming. "The New MVP? Inside the AI Playbooks of the Red Sox and Bruins," hosted by Wasabi Technologies, examines how Boston's professional sports teams are incorporating AI into their operations. At Fenway Park, Air Space Intelligence hosts "Hacking the Fourth Dimension with ASI" beginning at 9 a.m. At Havana Event Space in Cambridge at 2 p.m., "How to Actually Build at the Speed of AI and Outship a Bigger Team" addresses operating realities for lean AI-powered teams.

Biotech AI Hackathon and Saturday Build Days

Saturday is the week's intensive build day. The AI x Bio Hackathon, co-hosted by Absentia Labs and Ginkgo Bioworks, begins at 9 a.m. in the Seaport District and brings together AI engineers, computational biologists, and clinicians to prototype solutions at the frontier of life sciences. The AI Agents in Healthcare Hackathon runs simultaneously at 10 a.m. in Cambridge. The Always-On Agent Hackathon hosted by Rasa at 10 a.m. in Kendall Square challenges participants to build persistent digital coworkers. The Biotech Pitch Competition from 2048 Ventures and BioLabs also takes place Saturday.

Sunday closes the week with the Multi-Agent Orchestration Hackathon with Weights & Biases at MIT, hosted by CoreWeave beginning at 9 a.m., inviting participants to build production-ready multi-agent systems.

Curated Tracks for Every Audience

The official calendar organizes events into tracks: AI + Infrastructure, Bio + Health, Hackathons, Deep Tech & Robotics, and dedicated tracks for Students, Founders, Engineers, and Investors. Platinum sponsors include a16z, Fenwick, HSBC, and IBM; gold sponsors include Adobe, Atlassian, AWS, Cloudflare, Deel, Fireworks AI, and Google for Startups.

The Perkins DisabilityTech Investor Summit at MassBio's Cambridge headquarters, a four-hour session focused on accessibility technology investment, represents a programming dimension that sets Boston's edition apart from Tech Weeks in other cities — a reflection of the region's concentration of healthcare institutions, research universities, and mission-driven founders.

Frequently Asked Questions

Is Boston Tech Week 2026 free to attend?

Most events during Boston Tech Week are free to attend, though some are invite-only or capacity-limited. Attendees register individually for each event through the official calendar at tech-week.com/calendar/boston, and hosts confirm attendance directly. There is no single ticket or registration that covers the entire week.

What events are at Boston Tech Week 2026?

Boston Tech Week features more than 572 individually hosted events spanning panels, hackathons, pitch competitions, mixers, fireside chats, and investor dinners. Programming is organized into tracks covering AI and infrastructure, biotech and health, deep tech and robotics, and dedicated programming for students, founders, engineers, and investors.

How does Boston Tech Week differ from a traditional tech conference?

Unlike a traditional conference held in a single venue, Boston Tech Week is a decentralized series of events hosted by individual companies, startups, and funds across multiple neighborhoods including Kendall Square, the Seaport District, Back Bay, and Cambridge. Andreessen Horowitz presents and coordinates the week but does not host or ticket the majority of sessions.

What is a16z's role in Boston Tech Week?

Andreessen Horowitz (a16z) presents the event and has brought the Tech Week format — previously held in New York, San Francisco, and Los Angeles — to Boston for the first time in 2026. The firm provides organizational support and grants for some programming, but individual companies and organizations host and manage their own events independently.
