AI made it cheap to produce ads. But that doesn’t mean it’s easy to make good ones. That takes taste, and that’s the part we keep in-house: the idea, the angle, the story, the mood. AI handles execution, so we can test dozens of concepts for the price of one and find what works before the budget runs out. Now, a flop only costs a few hours of work. Then we make the next one.

The creative methodology

Anyone can ship an ad.
We ship winners systematically.

Every concept moves through the same four steps. We read the data, turn it into something worth testing, make it quickly, and then test it for real. What we learn from each round feeds the next one.

  1. 01

    Research

    We start in the data, not in a creative tool. Signal is built on the thousands of campaigns we’ve run ourselves, so it shows us what’s already converting for you and for brands like yours. The concepts we pursue come from our own results, not a hunch.

  2. 02

    Storyboard

    This is where the taste comes in. We turn the data into concepts worth testing, taking big swings instead of safe variations. We set the angle, the story, and the mood before anything gets made, so each ad is built to sell, not just to look good.

  3. 03

    Production

    Now our AI goes to work. We tell it the shots, the angles, and the vibe, and it produces real, on-brand video, static, and UGC in a fraction of the usual time and cost. Our ads are AI-made, human-directed.

  4. 04

    Test & Scale

    Shipping the ad is the easy part. Every variant has to earn its spend, so winners get more budget and the rest get cut. And testing never stops - the moment a winner starts to fade, the next proven one is ready to take its place.

What we make

The full creative stack.

Video Ads

The first second decides whether anyone watches the rest, so the hook is everything. Our AI lets us make and test dozens of hooks in a few days instead of weeks, so we find the one that stops the scroll fast and build the video around it.

Performance Static

Our AI generates hundreds of on-brand options modeled on what’s already winning, so we test the strongest right away and scale what performs, instead of pouring production time into ads that were never going to work.

UGC & Creator Content

We start with AI UGC that feels like a real recommendation, not an ad, and test it fast and cheap. When a concept proves itself, we bring in our vetted creator network to shoot the real version, so you only pay for live production once you know the idea converts.

Storyboarding & Concepting

Before we spend anything on production, the idea has to earn it on paper. We work from brief to storyboard with a clear hypothesis attached to each concept, so the production budget only goes toward ideas worth testing.

Landing Pages

The ad earns the click, but the landing page is where the conversion actually happens. We design, build, and A/B test pages that carry the same message as the ad, so the traffic you paid for doesn’t leak away.

The tools we use

We don't guess at creative.

We run it through our testing engine.

And scale what the data proves.

The challenge

Running Google Ads at modest returns with no way to scale. A previous agency had left messy infrastructure - overlapping keywords, shared budgets cannibalizing campaigns, and only two channels live.

What we did
  • Paid across Google, Meta, Bing, and LinkedIn
  • Rebuilt the campaign architecture from scratch
  • Keyword + intent segmentation
  • New ad copy and retargeting
  • Channel expansion + platform recovery
Results
  • ~4x increase in revenue from paid in 12 months
  • Expanded from 2 to 4 active channels
  • Hit the best-performing month in company history

Three ways to work together.

Our Model

The agency model was never built for startups, let alone for the AI era. Ours is.

Senior startup-growth talent, a full-stack team, proprietary AI, and built-in distribution, brought together in one model the old agency never could.

FAQ

Questions, answered.

Everything teams ask before handing us their paid budget. Still stuck? We’re one conversation away.

Let's talk

Traditional agencies aren’t built for startups. They’re built for big clients and their own margin, which means an army of junior account managers, standardized playbooks, and bloated meeting cycles. Worse, they’re built to sell, not deliver. You meet their polished executives during the sales process, hear all about the awards they’ve won and how elite their team is, and sign. Then, unbeknownst to you, you’re handed to a junior team, shielded behind an account manager who’s really a salesperson in a strategist’s clothing. Meanwhile startups sit at the bottom of the priority list while the senior people stay on the bigger accounts.

Most agencies are wrapping the same off-the-shelf tools everyone else has, trained on the same public data, so they get the same average outputs. Signal is our own AI, trained on a decade of data no one else has from 7,000+ startups, our Growth Engine methodology, and a community of 110,000+ operators sharing what’s working directly from the front lines. It gives our strategists superpowers, helping them move faster and spot opportunities they’d never spot alone, while the highest-leverage work, the strategy and the hard problems, stays firmly with our people.

Bring a goal and whatever brand assets you already have, and we handle the rest, from the first concept through final delivery. If you’ve got footage or brand guidelines, we’ll use them. If you don’t, that’s fine too; we don’t need them to get started.

A designer makes a handful of assets, then waits for feedback before making more. We run it as a system instead, with a steady stream of concepts that get produced fast and scored against real performance. The AI handles the volume, which frees up our senior people to spend their time on the ideas themselves.

Enough that the test actually tells us something. We’ll run several variants of each concept and test them against each other, then cut the ones that underperform and put more budget behind the ones that work.

It stands on its own. A lot of our clients run their own media and just want stronger creative to feed it. Creative and media do work better together, though, so if you want us to handle both, we can.

We measure it on outcomes rather than opinions. Depending on your goal that’s ROAS, CPA, click-through, or some mix of them, and Signal scores every variant so the next round builds on whatever the last one proved.

Your Growth Experiments Are Lying to You

Growth experiments should be your most powerful tool. But most teams run them wrong - optimizing for velocity over learning, testing the wrong variables, and declaring winners based on hope.
