01 Digital twins

Digital twins built from what ten million people actually do.

A digital twin is a working copy of a real person's behavior. Twin IQ builds one for each of the 10 million US people in the Crosswalk panel. It comes from what they watch, search, buy, and pay for, not from what they tell a survey. Put a plan, a title, a price, or an idea in front of the twins and see what happens before you spend.

02 The short version

Twin IQ lets you test your spend on ten million real lives.

Every person in the Crosswalk panel gets a twin built from what they do. You put in a plan, a title, or an idea. Prometheus runs it forward on the twins and returns the odds, the audience, and the package that earns the most. Then it sets the plan live inside the ad platforms and keeps score.

What it is

One twin per person: observed behavior, 4,600+ audiences already read, outside anchors, and what each person pays.

Why now

Twin and AI research tools raised more than $250 million in the past year. Every one of them is built on what people say, none on what they do.

Why Crosswalk

The only panel that sees each person's whole digital life, joined to products that already read live campaigns.

03 What a digital twin is

Synthetic data that starts with real data.

Most synthetic data starts with a survey, or with a language model guessing how a type of person would answer. Crosswalk's digital twins start with the record: a real person's digital life over time, kept in order with timing. The twin learns how that person responds, what they pay, and when they leave. The synthetic part is what you do with it. Run a plan the person never saw and read how people like them respond.

Digital twin: One real person's observed behavior, turned into a copy that can respond to something new.
Synthetic data: The outcomes the twins produce when you run a plan they have never seen. New data, built on real behavior.
Synthetic audience: The twins a plan would reach, sized, described, and projected to the US population.
Not a survey: No twin here was built from a questionnaire, an interview, or a model guessing at a type of person.

04 The twin

What one twin carries.

Four layers of fact and two of judgment, for each of ten million people.

01

Observed behavior.

This person's watching, searching, buying, paying, and clicking, kept as a sequence with timing, across every surface.

02

The corpus.

Everything already read about people like them: 4,600+ audiences, every journey, every attribution, churn, and trend read.

03

Outside anchors.

Public facts the panel cannot see, fixed on as anchors: box office and streaming history, platform reach, ad benchmarks, prices paid.

04

Response and price.

Past responses to content and ads, how long each took, the prices this person paid, and the ones they walked away from.

05

Lifecycle.

Their standing with each title, platform, or brand: discovering, trying, in the habit, lapsing, or coming back.

06

A track record.

How well twins like this one forecast the campaigns in the corpus, published next to every new read.

05 How it works

Four steps from the plan to the result.

Put it in, run it forward, make it better, set it live and prove it.

01

Put it in.

A plan, a budget, assets, a trailer, a script, a logline, a creator roster, or a price, typed to Prometheus or attached as a file.

02

Run it forward.

The twins the plan can reach respond the way people like them did before. Thousands of runs become odds and ranges.

03

Make it better.

Prometheus works every lever and ranks them by what they earn, then returns the package that reaches the goal for less money.

04

Set it live.

Approve it, and it runs inside the ad platforms, moves money toward rising signal, tests, and keeps the ledger of what it saved.

Twin IQ plan intake screen: a plan described in plain words on the left, read back as editable fields on the right, with the goal, budget, window, platforms, assets, audience, rule for moving money, and lift test — Step one, as a screen. You describe the plan the way you would say it. Prometheus reads it back as fields you can edit, then runs it on the twins. Product mockup; figures are illustrative.

06 Product one

Launch Lab.

A plan run on the twins before the money goes out. For studios, streamers, labels, and game publishers with a release to open.

What the client gets

Three plans side by side: as allocated, signal-led, and the minimum that still hits the goal
Odds and ranges on the goal, week by week
The levers ranked by what they earn
A holdout sized to prove lift at the lowest spend

Example. The signal-led plan sells 23% more opening-weekend tickets on the same budget, and the review clips lead instead of the trailer.

Twin IQ Launch Lab screen: two plans compared on opening-weekend tickets with odds and ranges, a week-by-week chart of tickets per $100K, and the levers ranked by what they earn — Launch Lab. Product mockup; figures are illustrative.

07 Product two

Greenlight Lab.

The odds on a title or a bare idea before money is committed. For development, acquisitions, financing, and slate decisions.

What the client gets

A logline, script, trailer, roster, or pilot goes in
The range of outcomes on each platform
The audience that shows up, sized by cohort
Levers ranked by value, with one package to run

Example. A seven in ten chance the limited series clears 4M viewers in its first month on Peacock, and the lead carries 71% of the reach.

Twin IQ Greenlight Lab screen: first-month viewer ranges by platform, the comparable titles the twins recognize, the audience that shows up by cohort, and levers ranked by value with a recommended package — Greenlight Lab. Product mockup; figures are illustrative.

08 Product three

Spend Engine.

The connected loop that moves money toward what is working. For brands, agencies, and partners with always-on paid media.

What the client gets

Meta, Google, Amazon, and TikTok connected, read and write
Daily moves by chip, or on the rule you set
A/B tests spun from the trends
Lift read against a matched twin holdout

Example. A $50,000 test on matched twins reads with the confidence of a seven-figure one, and the account moves budget the next morning.

Twin IQ Spend Engine screen: four connected ad platforms with daily spend and conversions, the moves Prometheus recommends, a running test, and the savings ledger — Spend Engine. Product mockup; figures are illustrative.

09 Who it is for

Four kinds of buyer, one engine.

Each one brings a decision that today gets made on a hunch, a survey, or last year's numbers.

01

Studios and streamers.

P&A and launch teams opening a film, a season, an album, or a game. Launch Lab, per release.

02

Development and slate.

Greenlight, acquisitions, and financing decisions. Greenlight Lab, per read or per slate.

03

Brands and agencies.

Always-on paid social and search. Spend Engine, connected to the platforms they already buy.

04

Partners through the API.

Platforms and agencies that build on Crosswalk: reads at rate-card prices, with the savings ledger returned in the API.

Next to the others. Profile IQ tells you who the audience is. Digital Journey IQ shows the path they took. Attribution IQ gives each touchpoint its credit. Twin IQ takes the same people and runs the plan you have not spent on yet.

10 Why real behavior

A survey-built twin cannot tell you what a dollar will do.

Survey-built twins and synthetic respondents are good at what people say. Spend decisions depend on what people do: whether they click, watch, pay, come back, or leave, and how long each takes. Crosswalk's twins were built from that record, and they are checked against live campaigns.

11 The track record

Every forecast sits next to what happened.

Before any client sees a forecast, the engine runs on the past. Every campaign and launch in the corpus is replayed from the day before it started, with only what was knowable then, and scored against the result. The score is published inside the product and updated as live campaigns land.

Before you trust it

The engine's score on the past campaigns that look most like yours is on the page with the forecast.

While it runs

The live signal comes in daily. The forecast is re-scored and the plan moves with it.

After it lands

What was forecast, what happened, and what the twins saved go into a ledger you can open any time.

12 Privacy

Twins, not people.

Each twin stands in for one of the 10 million US panelists who chose to be counted. Identity is kept apart from behavior, and sensitive details are removed before anything is stored. Prometheus never answers about one person. It answers about the group a person is counted with, and every projected figure carries its base.

13 Questions people ask

Digital twins and synthetic data, in plain words.

What is a digital twin in market research?

A digital twin is a copy of a real person's behavior that can respond to something new. In research it stands in for a survey respondent. Crosswalk builds one from observed behavior over time for each of 10 million US people. A question about a plan or a title is answered by how people like that behave.

What does synthetic data based on real data mean?

Synthetic data is data that was produced rather than observed. Crosswalk produces it by running a plan on twins built from real behavior. The inputs are real: what people watched, searched, bought, and paid. The output is new: what those same people would do with a plan they have not seen yet.

How is this different from a synthetic panel or AI respondents?

Most synthetic panels start from surveys, interviews, or a language model answering as a type of person. They can tell you what people say. Crosswalk's twins start from what people do, and they are checked against live campaigns rather than against another survey.

How accurate are the digital twins?

Every forecast is scored against what happened, and that score sits next to each new read inside the product. Before any client sees a forecast, the twins are run on past launches and campaigns using only what was knowable at the time.

What can I test on the twins?

A media plan and its budget split, a title, a script, a trailer, a bare idea, a creator roster, a price or a promotion, a release week, an audience. Anything you would otherwise spend money to find out.

Does it connect to our ad platforms?

Yes. The recommended plan exports in the shape each platform's buyer uploads from day one. Connected accounts on Meta, Google, Amazon, and TikTok add daily reads and, with your approval, the moves themselves.

Is any personal data used or sold?

No customer files are sold and no individual is identified. The panel is opted in, identity is kept apart from behavior, and clients receive group statistics projected to the US population.
