To become a Spacer, get Flux certified.

Flux-1 certifies professionals who have genuinely integrated AI into their daily workflow. Not tool users -- Spacers. People who produce more in a morning than most produce in a week.

The Flux-1 challenge is a 1-hour build task drawn from a real industry problem. You will solve the business problem: concept, copy, design, and deployment. The scoring rubric weights output completeness and execution quality most heavily at this tier.

Flux-2 certifies professionals who operate across multiple domains simultaneously. Strategy and execution. Depth and breadth. The 2-hour window is long enough to demand coherence across functions -- and short enough to expose anyone who can only move fast in one direction.

The scoring rubric shifts at Flux-2. Domain breadth becomes a serious weight. Output completeness alone will not carry you. You need to demonstrate that you can build across a full business function, not just execute a single deliverable.

Flux-3 is where the Flux Standard starts commanding real compensation conversations. At this tier, you are operating at the scale of a 30-person organization -- delivering outcomes that used to require entire companies, in timeframes that used to require entire quarters.

The 4-hour window demands sustained strategic judgment across every business function. The rubric weights strategic judgment at 15% and domain breadth at 20%. A technically excellent executor who cannot make and defend high-stakes decisions will not pass Flux-3.

Flux-4 is the credential that signals institutional-scale capability. At this tier, you are replacing a division -- operating with the strategic depth of a leadership team and the delivery speed of an engineering organization. The 8-hour window is long enough to expose weak systems thinking.

The Flux-4 problem contains deliberately ambiguous constraints, competing stakeholder interests, and resource limitations. The rubric weights strategic judgment and domain breadth at 40% combined. Speed matters -- but a fast wrong answer fails.

Flux-5 is the hardest Flux certification to earn. Fewer than 1 in 2,000 candidates pass. Like every Flux credential at Flux-1 and above, Flux-5 maintains via Flux Education Units over a 24-month window.

The Flux-5 challenge is a 12-hour venture launch. You will build a venture-ready company from scratch -- live product, go-to-market foundation, financial model with bear/base/bull scenarios, and an investor-ready pitch. No incorporation required. Everything else is real. This is also what it looks like to be handed a blank mandate inside a Fortune 500 and told to build a new product line alone.

The scoring engine evaluates not just what you built -- but whether you identified the unstated constraints, second-order risks, and market dynamics that were not in the brief. Most candidates solve the problem as written. Flux-5 Architects solve the problem beneath the problem.

Flux-5 is the apex of the Flux Standard -- the highest pass threshold (88/100), the longest challenge (12 hours), and the lowest target pass rate (0.05 percent). It is calibrated as the reference against which every lower tier in the rubric is anchored.
