  • We're not just building the next Salesforce/HubSpot, but AI-first GTM stack

  • Founded by the team that scaled Smartly.io to $100M+ ARR

  • Backed by top-tier global VCs

  • Looking for a sharp generalist who can operate across every part of the business

  • This is the closest thing to being a founder without starting a company

The role

You'll work directly with the founders and founding team on everything that isn't engineering. Operations, finance, customers, GTM, fundraising, reporting - all of it. The scope is deliberately wide because early-stage companies don't have neat job descriptions. They have problems that need solving.

One week you might be preparing a data room for our next funding round. The next you're solving a bottleneck in our customer onboarding. The week after that you're building out our financial reporting or helping close a key partnership. The common thread: you figure out what needs to happen and you make it happen so we can run fast as a team.

This is not a support role. You'll own outcomes, not tasks.

What you'll do

  • Partner daily with the founders on strategy, priorities, and execution across the entire business

  • Own operations: financial reporting, legal, vendors, tracking goals and internal processes

  • Drive GTM execution: customer onboarding support, sales operations, pipeline management

  • Support fundraising: investor materials, data rooms, pipeline tracking, due diligence prep

  • Manage investor communications with the founders

  • Build and improve internal systems and processes as we scale from founding team to growing org

  • Run cross-functional projects that don't have a clear owner yet - because at this stage, most things don't

Who we want

We're looking for a generalist with a founder mindset. Someone who's comfortable with ambiguity, moves fast, and doesn't need to be told what to do.

If you need clear boundaries and well-defined processes to do your best work, this isn't the role. If you thrive in chaos, get energy from building things from scratch, and want to learn what it takes to scale a company from the inside - let's talk.

You need

  • Startup DNA - You've worked at early-stage startups, in venture capital, or in top-tier consulting. You understand the pace and the stakes. You've built something yourself.

  • Speed and bias for action - You default to doing, not deliberating. You ship work that's 80% perfect today rather than 100% perfect next month.

  • Comfort with ambiguity - You can take a vague problem, break it down, and drive it to completion without hand-holding.

  • Strong communication - You write clearly and concisely. You can represent Zero to investors, customers, and partners with confidence.

  • Financial literacy - You're comfortable with numbers, spreadsheets, and basic financial modeling. You don't need to be a CFO, but you need to hold your own.

  • Founder mindset - You think beyond your role. You care about the company winning, not about job title boundaries.

Bonus points

  • Experience in B2B SaaS, CRM, GTM tools

  • Background in VC or supporting fundraising processes

Why Zero

  • You'll join at the earliest possible stage of a company going after a $100B+ market

  • Founded by a team who've done it before

  • Backed by top-tier global investors

  • Working with the best high-growth AI startups in SF, NYC, London, Berlin, and Stockholm

  • High autonomy, real ownership, and direct impact from day one

  • A tight-knit team that ships fast and holds a high bar

How we work

  • Speed first: We execute faster than anyone else. Quick decisions, rapid shipping.

  • Customer intimacy: We build alongside our customers, not in isolation.

  • Founder mindset: Everyone acts like an owner. No micromanagement, real responsibility.

  • All-in: We're here to build the best company in the category, not the most comfortable workplace.

  • Global from Day 1: We have customers from San Francisco to Sydney and operate with a global ambition
