Access. Rights. Scale.

Early Rights AI

Helping VC/PE secure options and exclusivities in AI before the market sets the price.

SEIKOURI originates operator-vetted deals in pre-market AI and engineers rights—options, exclusivities, first refusal—aligned to your thesis. We pair deep technical and team diligence with term design that protects downside and amplifies upside, so you enter early, price rationally, and exit stronger. Leverage first, through relationships—not algorithms.

AI Underground Access

A private, operator-led backchannel into pre-market AI—opened by relationships, not algorithms.

AI Underground Access puts you inside the founder circles and invite-only channels where tomorrow’s AI forms. We surface real fit, earn trust, and open doors early—before the market sets the price. No marketplaces, no vendor spam. Just curated, rights-aware introductions and the context to move from whisper to working session while it’s still affordable.

Stealth-to-Scale Partnerships

Turning early access into enterprise rollouts—pilots that graduate, rights that defend, results that scale.

SEIKOURI choreographs the path from first meeting to multi-region deployment: rights-backed pilots, security and data guardrails, SLAs, enablement, KPIs, and change management. We de-risk integration while protecting your position, so wins become repeatable programs—not one-off demos. Founders get faster enterprise traction and better rounds; buyers get durable advantage competitors can’t copy.
