Overview
At Gravity we're building an Ad Network for AI. Our goal is to make AI free.
There are 1000s of companies developing AI tools across every niche, demographic and enterprise vertical that exists, but AI is expensive, and in order for these companies to successfully develop and deliver their products at scale, they need to support offering their products for free.
Gravity was founded in July 2025. We've raised $39M to-date across our Seed and Series A from top investment firms like Caffeinated, Basis Set, Lightspeed Venture Partners and Committed Capital to help fuel our ambitions to make AI free. We believe ads in AI will grow into the biggest advertising channel in the world over the next decade. We're an 8 person team based in San Francisco and growing quickly.
Our CEO Zach Oldham previously founded Flax Labs, a performance marketing agency that managed $200M+ in ad spend and our CTO Leo Martinez scaled his own HFT system to $30M+/month on his own capital.
As a Founding SDR, you'll help us execute and build our GTM playbooks as we start scaling up our success with winning and onboarding enterprise advertisers.

What you bring to the table
You hate losing.
You move quickly.
You ask great questions.
You're naturally curious.
You communicate exceptionally well.
You're resourceful.
You're comfortable hearing "no."
You take ownership.
You have a severe bullshit allergy.
You're excited by AI and where it's headed.
Experience selling SaaS, advertising, agencies, developer tools, or technology is a bonus, but it isn't what gets you hired.
We care far more about how you think, how quickly you learn, and how much ownership you're willing to take.
This probably isn't for you if...
You're looking for an easy SDR job.
You need someone checking in on you every hour.
You prefer process over ownership.
You're uncomfortable with accountability.
You want predictable days.
You're just looking for another sales job.
If that's what you're after, you'll probably be happier somewhere else.
