Founder's Office - Build the Future of Shopping

A co-pilot seat and a chance to help build the ad infrastructure for a world where agents shop, decide, and buy.

Pier39 crossed 7-figure gross revenue within its first year. We work with 150+ leading DTC and e-commerce brands. We move from discovery to live in hours, sometimes. And we're only getting started!

The World We're Building Toward

The advertising stack as we know it was designed for humans, humans who scroll, click, browse, and decide. That stack is about to be fundamentally disrupted. And the ad infrastructure that was built for a human attention economy is simply not designed for what comes next.

We are building the ad stack for the agentic era.

Pier39 already sits at one of the highest-intent surfaces in commerce, the moment right after a transaction is confirmed. We've proven we can monetize that moment at scale, for both merchants and advertisers, with zero friction. But that's the foundation, not the ceiling.

The bigger bet is this: as AI agents become the primary interface through which people interact with the internet, the rules of advertising, targeting, and monetization will be rewritten from scratch. Who gets to reach an agent? How does a brand earn relevance in an AI-mediated decision? What does a reward, an offer, or an ad even look like when the recipient is a model, not a person?

These are the questions we are positioning ourselves to answer. We want someone in the Founder's Office who sees this frontier as clearly as we do, and is hungry to help build on it.

The Role

You will work directly with the founder. You'll be the second brain on decisions that matter and the hands that execute when speed counts.

We move at a pace that most companies talk about but don't actually live. Discovery to live in hours. Decisions made on data and instinct, not committee. If that pace energizes you, read on.

What You'll Own

Growth & Revenue

→   
Run growth experiments
from hypothesis to execution to measurement. You own the outcome, not just the task.

→   
Drive partner acquisition
— identify the right merchants, build the outreach, close conversations, and get them live.

→   
Shape GTM strategy
for new verticals, ad formats, and advertiser categories as the platform expands.

→   
Own the metrics that matter
— active publishers, revenue per order, advertiser retention, conversion rates.

Agentic Product & Automation

→   
Build and ship AI agents
for growth, onboarding, customer health, and reporting — if it can be intelligently automated, it should be.

→   
Think through the agentic ad stack roadmap
— how do targeting, relevance, and monetization work when the audience is an AI model? Help develop Pier39's point of view.

→   
Bring customer learnings into product
— synthesize feedback from brand partners and advertisers into sharp, actionable inputs for the roadmap.

→   
Champion the right product bets
— distinguish signal from noise, and push hard for what actually moves the number.

Founder Leverage

→   
Prepare investor materials, strategy decks, and memos
— crisp, well-reasoned, and written in the founder's voice.

→   
Lead cross-functional initiatives
that don't fit neatly elsewhere, e.g., competitive intelligence, pricing, new market entry, partnerships.

→   
Represent the founder
in meetings and decisions where they can't be present.

→   
Spot problems early and act
before they become escalations.

Who You Are

→   
You move before you're asked.
You identify what needs doing and you start.

→   
You own outcomes completely.
When something is yours, it gets done — not handed off, not stalled.

→   
You think in agents and systems.
You've built workflows with LLMs, you've deployed automations, and you naturally ask 'can this be a system?' before 'can I do this manually?'

→   
You hold the big picture and the detail at once.
Vision and execution in the same head.

→   
You're wired for speed.
You're comfortable making good decisions fast, shipping, and iterating.

→   
You're trustworthy at the core.
You are a part of sensitive conversations, financials, strategy, so discretion is non-negotiable.

→   
The future of advertising genuinely excites you.
Agentic AI, the death of the cookie, intent-based targeting — you follow this space because you're curious, not because it's on your job description.

→   
You communicate with precision.
In writing, in rooms, on calls — clear, persuasive, and human.

Background that fits:

→   1–4 years in a high-velocity startup, early-stage company, or consulting

→   Experience spanning at least two of: growth, product, customer success, ops, or strategy

→   Hands-on experience with AI/LLM tooling — you've built agents or automated real workflows

→   E-commerce, AdTech, or SaaS background is a strong plus

A Note on Pace

We move from discovery to live in hours. We make decisions fast. We don't wait for perfect when good is enough to learn from. Some weeks will feel like a month. That's not a warning, for the right person, it's the best part of the job.

What You'll Get

→   
Proximity to the founder
— every dimension of how a breakout company gets built.

→   
Real equity
— you're an early team member and will be compensated like one.

→   
Performance bonus
— tied directly to the outcomes you own.

→   
Competitive base salary
— not a constraint for the right person.

→   
A front-row seat to the future of advertising
— agentic AI, intent-based monetisation, the infrastructure layer for what comes next.

→   
The professional growth of a decade, compressed into a year.
