ETHDenver is the largest Ethereum builder week in the world, and ETHDenver 2026 runs February 17-21 at the National Western Center in Denver. FORKOFF runs the hacker-house and side-event activation for AI and Web3 founders shipping at the BUIDLathon: pre-event builder narrative, an on-site side event where the developer cluster gathers, Ethereum-native KOL placement, and a post-event clip cascade. One operator, one ledger, audit-tracked outcomes.
Most teams register + hack + hope. Some throw one side event + hope. FORKOFF runs the ETHDenver week as a 14-day operating cycle.
ETHDenver is the one week where developer signal, not allocator signal, is the currency. If your milestone is technical, this is the room. Compounds in ways the institutional weeks do not for builder-led teams.
The BUIDLathon concentrates protocol engineers and hackathon teams at a density no other US week matches. Testnet launches, tooling debuts, and open-source releases land with the exact audience that adopts them first.
Several hundred community side events run across the five days. That is a feature, not noise: a well-produced FORKOFF side event pulls the right 40 people out of a 25,000-person crowd into one room with a recorder running.
Seed and pre-seed funds source ETHDenver specifically to find teams shipping at the hackathon. The five-day format gives founders repeat contact with the same scouts, which is how technical conviction gets built.
The Ethereum creator and KOL set is on the ground and posting all week. Every on-site moment compounds across the EVM-native timeline, and the post-event clip cadence rides the residual attention curve for 30 days.
The week splits into the BUIDLathon hackathon floor (the center of gravity), a several-hundred-strong side-event web running across RiNo and downtown, and a hacker-house circuit that runs all five days. Activating well means owning a slice of the side-event web, because the main floor is for building, not meetings.
Feb 17-21, 2026
Main event at the National Western Center (Stockyards Event Center), Denver, CO. Side events concentrated in RiNo and downtown. Hacker houses spread across the city for the full five-day window.
25,000+ in 2025 across 125+ countries. Free admission keeps the top-of-funnel wide, which is why the side-event web is the densest on the US calendar.

| Day | Date | Motion | FORKOFF owns |
|---|---|---|---|
| Tue | Feb 17, 2026 | BUIDLathon opens · pre-conference ICP 1:1 meetings set up | Meeting calendar + qualified-intro routing |
| Wed | Feb 18 | Hacker-house circuit warm-up · founder posts from the floor | Daily post + on-site clip cadence |
| Thu | Feb 19 | FORKOFF side event in RiNo (builder breakfast or protocol panel) | Production + KOL invites + recording |
| Fri | Feb 20 | On-site podcast recording day · 3-4 founder and judge interviews | Studio + production + same-week clip pipeline |
| Sat | Feb 21 | BUIDLathon finals · KOL night · partnership-conversation closes | KOL proof + per-post tracking |
| Sun | Feb 22 | Founder thread recap of the week · post-event clip cascade live | Thread craft + distribution sequencing |
Two weeks of pre-event builder narrative plus a 30-account developer-cluster activation plus Denver-specific intro engineering. You leave with a verified record of qualified intros surfaced before you land for the BUIDLathon. Lite scopes a single track: narrative drop, or one hacker-house co-host night, or one RiNo side-event slot. Selective on ICP, capped per quarter.
All tiers carry the verified record plus qualified-pipeline reporting. Tier scales scope, not philosophy.

FORKOFF has run activations across 42 events since 2023, per our own operating record, including Korea Blockchain Week, ETHDenver, and Token2049. Those were not booth rentals. They were curated gatherings and side events sized between 100 and 250 attendees each, built around a pre-event narrative, an on-site cadence, and a post-event compounding motion. ETHDenver, held in Denver every winter, is one of the densest builder crowds on the calendar, and the playbook on this page is drawn from the reps we have actually logged in that room, not from a slide someone reused.
ETHDenver skews toward engineers and protocol founders who fly in to build during the BUIDLathon, not to sit through a pitch. A brand that shows up with a booth and a QR code gets ignored; a brand that shows up with a technically credible reason to talk gets a hackathon table surrounded. Across our 42-event history the pattern held every time: the teams that treated the side event as a working session, a workshop, a builder dinner, a focused demo, out-converted the teams that treated it as a logo placement. Denver punishes the sponsor reflex harder than most rooms because the audience is there to write code, so the on-site cadence we run leads with substance and keeps the sales motion one step behind the value.
Because we have run the pre-event to post-event loop dozens of times, we do not start an ETHDenver engagement from a blank page. We know when to open the narrative so it peaks the week of, which side-event format matches a builder audience, and how to keep the momentum alive after everyone flies home. The full method sits on the event management service page, the calendar view of every activation window lives at the events hub, and if your team is weighing Denver against Asia, the Token2049 Singapore breakdown runs the same math for a very different room.
