A platform for conditional commitments: pledges to act only when N peers agree, so lab employees, researchers, and policy coalitions can coordinate high-stakes collective action.

Updated 07/14/26 · Edited by orgWhat we're building:
One of the central challenges in AI safety is addressing coordination problems upstream of risks. Spartacus.app was and is designed as human coordination infrastructure, using assurance contracts to build a critical mass of participants to a designated action threshold, with optional temporary anonymity to protect users in adversarial conditions.
The problem it addresses:
AI safety and governance are hostage to several perverse incentive structures and game-theoretic problems, such as arms-race dynamics between labs and rival nations, competitive market dynamics that crowd out adequate support for guardrails, and proprietary R&D frameworks that inhibit information sharing as a public good.
The highest-leverage safety-oriented actions are deterred by first-mover and defection risk, not by a lack of latent support. Ultimately, this principle is scale-agnostic and can be applied even to the highest-stakes coordination dilemmas.
Functionality:
Two-sided conditional-commitment marketplace matching organizers and participants.
Public campaigns surface common knowledge about a community's latent preferences.
Transparent, strong commitment signals create preference cascades and bootstrap a critical mass of support for proposals.
Action-enforcement mechanisms (social accountability, financial deposits) strengthen commitment signals and filter out symbolic or expressive support.
Optional anonymity until threshold protects privacy and removes first-mover risk.
LLM-enhanced campaign builder calibrates campaign structure and expectations to optimize for likely success conditions.
Next steps:
Phase one of http://spartacus.app validated parts of the mechanism, namely the increased leverage resulting from the synchronized action of a large group, but the central question of whether the Assurance Contract incentive alone can induce coordination remains partially unresolved. Does conditional commitment convert private willingness into collective action without the need for a charismatic organizer or an external forcing function?
We have LOIs from AI safety-oriented organizations that are ready and willing to experiment, with no new strategies or engineering involved. Either signatories won't coordinate even with common knowledge of mutual gain (in which case the key thesis is flawed), or they will commit at a specific threshold and under reciprocal criteria when no one would act first alone (verifying the thesis).

Theory of Impact
Updated 07/17/26 · By grantmaking.aiIncentive structures govern human behavior in predictable ways, but can generate paradoxical or perverse effects when they optimize for one set of outcomes people want at the expense of other outcomes that those same people also want. Short-term interests can undermine long-term ones, and narrowly selfish preferences can backfire when pursuing them makes everyone's future self worse off than if they had been more cooperative from the outset.
Assurance contracts, or conditional commitments, help people overcome bad incentive structures and coordinate around preferences for long-term or large-scale benefits that would otherwise be blocked by cross-cutting pressures to pursue immediate gains.
We have a short window of opportunity (a few years at most) to solve key coordination and collective action problems that will determine humanity's path. The forks in the road that lead to wonderful or catastrophic outcomes are likely to be immediately in front of us.
There are several use cases among the AI researcher, operator, and policy-making communities that want to coordinate on higher-level collective goals but lack the coordination infrastructure to do so.
