Location: NYC (onsite only – not remote)

Alliance is the leading accelerator for crypto founders. Since 2020 we’ve backed 300+ startups (Rain, Synthetix, Pendle, and many more), now collectively valued at $15B+.

We’re hiring an Executive Assistant & Office Manager to support both the day-to-day operations of our NYC office and provide direct support to leadership.

What you’ll do

Office Operations

  • Maintain a clean, organized, and welcoming office environment throughout the day
  • Stock and organize office supplies, snacks, beverages, and kitchen inventory
  • Ensure meeting rooms and common spaces are guest-ready at all times
  • Manage incoming mail, deliveries, and package organization
  • Coordinate with vendors, building management, cleaners, and service providers
  • Help maintain calendars for shared office resources and meeting spaces
  • Provide support to leadership and team members on day-to-day coordination tasks

Executive Assistant Support

  • Manage calendars, scheduling, and meeting coordination for leadership
  • Coordinate travel arrangements, reservations, and itineraries
  • Handle personal errands, appointments, and administrative tasks as needed
  • Track action items, deadlines, and follow-ups across workstreams
  • Assist with inbox management, document preparation, and light research
  • Coordinate logistics for meetings, guests, and external engagements
What we’re looking for
  • Strong organizational skills and attention to detail
  • Comfortable managing multiple priorities simultaneously
  • Strong communication and interpersonal skills
  • Ability to work independently and proactively identify needs
  • High emotional intelligence and discretion.
Strong qualifications (nice to have)
  • Startup, coworking, hospitality, or events experience
  • Experience working in fast-paced or highly collaborative environments
  • Interest in startups, founders, or entrepreneurship
Why NOT join us
  • Not willing to get hands dirty: doesn’t matter how important you were in past organizations; at Alliance we’re all builders, not managers (even though many of us were managers in past lives).
  • Prioritizing work/life balance: this role demands focus, hunger, and a career-defining level of commitment. You must be locked in.
  • Low agency: if you need someone else to set your priorities or keep you on track, you will fail.
  • You can’t relocate to NYC. This is non-negotiable: our founders are here, and so are we.
Why join us
  • Work with the most ambitious founders in crypto and AI. Learn firsthand from hundreds of startups succeeding – or failing.
  • Join a small, high-trust, high-performance team with outsized impact. We’re ex-Meta, WhatsApp, Coinbase, YC, and have collectively founded multiple venture-backed startups.
  • We’re backed by S-tier investors including Initialized Capital, Founders Fund, Multicoin, and Dragonfly, along with angels such as Balaji Srinivasan (ex-Coinbase CTO), Kevin Weil (CPO at OpenAI), Kevin Lin (Twitch co-founder), and Jeremy Allaire (Circle CEO), among many others.
  • Direct ownership and visibility: your work shapes how the next generation of founders discovers Alliance.
  • Career accelerator: this role sets you up, experience- and network-wise, for any high-impact path in crypto/AI – at startups, venture firms, or your own company.
  • Alliance startups are reinventing industries – from media to payments – and improving the lives of everyday people. You’ll have a front-row seat as they change the world.
