Remote | Equity-only | Early-stage AI/Education Startup


Maxibook is an early-stage AI startup rethinking how scientific knowledge is delivered, organized, and personalized.


We are building an Adaptive Knowledge System powered by dynamic knowledge maps and LLM-driven adaptive content, with an MVP expected by Q1 2026.


Our initial focus is on universities, research institutions, and publicly funded initiatives, with future expansion into the corporate HR sector (onboarding, continuous training, skill-gap reduction).


We are entering the fundraising phase and looking for co-founders who want to build something transformative from the ground up.


Tasks

CFO – Chief Financial Officer / Co-Founder (Funding & Institutional Relations)

  • Manage relationships with universities, research centers, and investors (EU + global)

  • Secure Horizon Europe, PNRR, national/regional grants

  • Design financial models, sustainability plans, and legal setup for early-stage growth

  • Be the institutional face that builds credibility with funding bodies and investors


COO – Chief Operating Officer / Co-Founder (Operations & Partnerships)



  • Translate vision into execution: roadmap, milestones, partner coordination

  • Act as operational backbone of the startup, working side by side with the CEO

  • Build and maintain relationships with C-levels and institutions worldwide

  • Oversee project execution, remote team alignment, and partner success


CTO – Chief Technology Officer / Co-Founder (Architecture & Tech Leadership)



  • Own the technical vision and drive the end-to-end architecture

  • Stack: React, Next.js, Supabase/SQL, MongoDB, Firebase, LLM (Mixtral/LLaMA/OpenAI)

  • Build scalable cloud-native infrastructure on GCP (Cloud Run, Compute Engine, Redis, BigQuery)

  • Innovate on LLM integration, prompt design, adaptive flows
