Senthiq
Continuously calibrated against real campaign data

Know how your audience reacts — before you spend the budget.

Senthiq simulates your target audience with synthetic personas — and continuously calibrates the results against real data from Meta and Google Ads. Every insight comes with a confidence score, not a number from a black box.

Why Senthiq

The speed of synthetic research. The trust of the real thing.

PROBLEM 01

Real research is slow and expensive

Recruiting respondents takes weeks and costs thousands. By the time results arrive, the decision has already been made.

PROBLEM 02

Synthetic tools are a black box

Existing tools give you no accuracy guarantees — no calibration, no confidence scores, hidden methodology.

SOLUTION

Senthiq combines both

Insights in minutes, continuously validated against real performance data. And when we're not sure, we tell you.

How it works

From audience description to insight in minutes

01

Describe your target audience

Demographics, behavior, purchase context. Senthiq builds a panel of synthetic personas from your description.

02

Run a simulation

Personas react independently to your product, campaign, messaging, price or design.

03

Get insights with confidence scores

Every result carries a confidence level and visible methodology — you know what you can rely on.

04

Validate where it matters

When confidence is low, Senthiq itself recommends supplementing with real human research.

Differentiators

Accuracy you can verify

Six things black-box competitors don't do — and Senthiq is built on.

Calibration loop against real data

Results are continuously compared with data from your Meta and Google Ads accounts — not just once at launch.

Bias & sycophancy reduction

Synthetic respondents tend to be overly positive and agreeable. Senthiq actively detects and corrects this.

Confidence scoring

No bare numbers. Every insight carries a confidence level you can actually work with.

Semantic scoring via embeddings

Scores aren't just numbers the model guesses. Each persona's answer is evaluated semantically via embeddings — more stable and robust to question phrasing.

Hybrid workflow

AI where it suffices. Humans where it matters. Senthiq itself suggests when to add real research.

Transparent methodology

How simulations work, what they are calibrated on and where their limits lie — all openly documented.

Transparency

No black box. The methodology is part of the product.

How simulations work, what they're calibrated on and where their limits are — all openly documented inside the app. Accuracy isn't a promise, it's a metric we measure and show.

±4 pts* average deviation from real campaign results after calibration
87%* of simulations above the 0.8 confidence threshold — the rest recommend real-world validation
100% of results ship with visible methodology and a confidence score

FAQ

Frequently asked questions

How accurate is synthetic research? +

Accuracy varies by domain and question type — which is exactly why we measure it. Senthiq continuously calibrates results against real performance data and attaches a confidence score to every insight. When confidence is low, we recommend real research outright.

How are you different from other synthetic tools? +

Competitors operate as black boxes — with no ongoing accuracy validation. Senthiq has a calibration loop against real data, active bias reduction, confidence scoring on every result and openly documented methodology.

Will this replace real research with humans? +

No — and we don't claim it will. Senthiq is a fast first filter for ideas and hypotheses. The hybrid workflow tells you when a result is uncertain enough to be worth taking to real respondents.

What data do I need for calibration? +

Performance data from your campaigns (e.g. CTR from Meta or Google Ads) or real survey results — upload them and Senthiq measures simulation accuracy against them. Without your own data, it runs on general calibration.

Your first insight in 10 minutes.

Describe your audience, run a simulation, and decide on data — not guesswork.
