What our clients say
“ClusterFast helped us identify a new untapped target audience: middle-aged women experiencing a relationship or marital transition. We validated this hypothesis with a Meta ad test in less than two weeks. Now it’s one of our key audiences, and thanks to ClusterFast insights, we create messaging that speaks directly to their needs and motivations.”

The problem
Most launches fail at the same spot: the wrong audience.
Whether it's a startup, a client project, or a new product line — teams guess who the customer is, and burn the budget proving themselves wrong.
Audience guesses get expensive
Ads go to broad audiences before anyone knows which segments are worth testing.
Weak signals mislead
Poor traction reads as “no demand” when it's really the wrong target.
Research is slow and costly
Weeks of surveys and interviews, $5,000–15,000 per study, before a single validated insight.
Learnings evaporate
Campaign results never become a structured record that makes the next test smarter.
The solution
A structured learning loop, not another AI output dump.
The product connects brief, segmentation, synthetic surveys, guided Meta Ads validation, and performance learnings into one repeatable workspace.
One page, ten minutes
3–15 ICP hypotheses with deep profiles
Synthetic surveys in minutes
Live Meta Ads experiments
Evidence, not vanity clicks
Every experiment feeds the learning graph
How it works
From a one-page brief to a proven ICP.
A workflow that tests your audience logic before you commit the budget.
Brief
Describe your product, market, and current assumptions. One page, ten minutes.
Discover
Get 3–15 ICP hypotheses with deep profiles: pains, triggers, behaviors, objections — each with a confidence score.
Test
Run synthetic surveys on digital twins of each segment. First validated insights in minutes, at near-zero cost.
Prove
Launch clean, one-variable Meta Ads experiments — auto-built campaigns with verified interest targeting, minimal budgets, paused until you approve.
Decide
Compare segments on real behavior, not vanity clicks. Kill, refine, or scale with evidence.
Compound
Every experiment feeds the learning graph — your next project starts smarter than the last.
Prediction vs. reality
Every synthetic prediction meets reality.
AI research is only useful if you know when to trust it. ClusterFast pairs what synthetic research & surveys predicted with what your real Meta Ads campaign showed — segment by segment: agreement, error, and time lag. You see exactly where the research was right, and the engine calibrates itself with every experiment.
No other platform measures this. We measure it on every project — from day one.
Built for the long run
Your ICP is not a one-time answer.
Markets shift, products evolve, audiences change. ClusterFast keeps validating and refining your ideal customer profile with every campaign you run. And each new product in your portfolio starts a new learning round — with an engine that already knows your brand, your customers, and what worked before.
The longer you work with it, the sharper it gets — that's why teams stay.

Use cases
Built for everyone launching something new.
ClusterFast is most useful when the next question is not only how to advertise, but who to sell to and why.
Startups & scaleups
Validate before you burn. Find out which of your assumed audiences actually responds — before the runway pays for the lesson.

Three ways to find your ICP.
Ask ChatGPT
Fast and cheap, but generic: no structure, no market data, no validation, and it forgets everything tomorrow.
Hire an agency
Thorough, but $5,000–15,000 per study, 3–4 weeks per iteration — and the learning stays in a PDF.
ClusterFast
Structured AI research, synthetic surveys, and live ad proof in one loop. Hours instead of weeks, tens of dollars instead of thousands — and it gets smarter with every project.
Start free. Scale when it works.
Free trial with enough tokens for your first ICP hypotheses and a deep segment profile. Paid plans from $49/month — a full validated research project costs less than a client lunch.
Trust and privacy
GDPR-first by design.
Your briefs, segments, and results stay private to your workspace. The learning graph reuses only anonymized, consent-based patterns — never your data itself. Patterns go live only after 20+ independent projects and human review.
Account-based workspaces
Each team works inside a private workspace.
Projects scoped to your account
Project data is filtered by authenticated ownership.
HttpOnly and Secure sessions
Session cookies are not exposed to client-side scripts.
Anonymized learning events
Learning signals avoid storing raw sensitive project details.
Consent-based learning
You control whether anonymized signals from your projects join the cross-customer graph.
No public sharing of project data
Outputs stay private to the active account workspace.
FAQ
Questions, answered.
How is this different from asking ChatGPT?+
ChatGPT gives you plausible text. ClusterFast runs a structured customer research loop — segmentation, buyer personas, synthetic surveys, live ad validation — grounded in anonymized patterns from real campaigns across 40 industries. And it remembers: every experiment makes the next recommendation sharper.
Can I trust synthetic respondents?+
Trust what's measured. We pair every synthetic prediction with the real ad outcome for the same segment, so you always see the engine's live accuracy. We're the only platform in the category that does this.
Do I need an ad budget to use it?+
No. Discovery and synthetic surveys work without spending a cent on ads. Live Meta validation is optional and runs on minimal test budgets you set — from about $8/day per audience.
How much does it cost?+
You can start free. Paid plans start at $49/month; a full validated research project costs tens of dollars in usage. The same study from an agency: $5,000–15,000 and 3–4 weeks.
Is my data safe?+
GDPR-first: your projects stay private to your workspace, sessions are HttpOnly/Secure, and the cross-customer learning graph uses only anonymized, consent-based patterns — no names, no emails, no client data.
