How to Research Hard-to-Reach Audiences Using Synthetic Personas

In market research, some audiences remain difficult — if not impossible — to reach using traditional sampling methods. Whether due to geography, rarity, sensitivity, or timing, certain segments simply fall outside the scope of feasible recruitment.

Think of:

• Rural seniors with limited internet access
• C-level professionals in niche B2B industries
• Rare disease patients or vulnerable communities
• Early adopters of pre-market tech
• Populations restricted by local laws or survey access barriers

When direct access fails, insight doesn’t have to stop. Enter synthetic personas — a scalable, AI-powered solution designed to simulate realistic responses from hard-to-reach audiences.

What Are Synthetic Personas?

Synthetic personas are AI-generated, data-driven profiles that mirror the behavior, attitudes, and demographics of real audience segments. Built on verified panel data, survey logic, and machine learning, these personas simulate how individuals in your target group would likely respond to research questions — even before they exist in the market.

Unlike fictional marketing avatars, synthetic personas from Syntheo are based on real-world patterns, modeled with the same logic paths and answer behavior you’d expect from a live respondent. They include:

• Simulated open-ends
• Logic-aware routing
• Demographic and psychographic layering
• Regionally contextual nuances

When to Use Synthetic Personas

Syntheo is designed for use cases where feasibility is low or timing is tight:

✅ Early-Stage Concept Testing

Test positioning, messaging, or product assumptions before target users exist.

✅ Low-Incidence Audiences

Avoid wasting time and budget on high screen-out rates by simulating responses from well-modeled synthetic targets.

✅ Inaccessible Populations

Generate insights from groups that are difficult to reach due to ethics, law, or geography.

✅ Emerging or Future Markets

Use forward-looking data models to simulate demand or adoption in markets where access is limited or lagging.

✅ Pre-Feasibility Exploration

Run simulations to validate survey logic and test likely hypotheses before committing to full fieldwork.

How It Works

Syntheo operates through a multi-layered process:

1. Audience Modeling
We define your target using patterns drawn from MyVoice, our proprietary global panel, alongside behavioral datasets and secondary sources.

2. Persona Generation
AI builds a virtual population of logic-aware, demographically diverse personas that behave like real respondents.

3. Survey Simulation
Your questionnaire is run through this synthetic cohort — with logic, piping, terminations, and scales fully respected.

4. Results Delivery
Receive structured output including datasets, dashboards, and synthetic verbatims, ready for insight extraction or stakeholder presentation.

Beyond Personas: Simulation and Bias Correction at Scale

Syntheo is just one part of our synthetic insight engine at DataDiggers. For clients seeking more than just persona-level understanding, we also offer:

• Modeliq, which enables simulation, scenario modeling, and strategic forecasting. Want to see how your pricing strategy performs across geographies or customer types? Modeliq allows you to test “what-if” scenarios using AI-modeled data — before spending on real-world testing.
• Correlix, which handles bias correction, data augmentation, and synthetic dataset generation at scale. It uses advanced statistical and machine learning models to generate high-integrity data that replicates real-world distribution — without compromising respondent privacy or quality. This is especially useful when adjusting for translation errors, cultural interpretation, or missing market data.

These tools complement Syntheo perfectly — helping agencies go beyond feasibility to full foresight, even in constrained or complex markets.

Reliable, Realistic, Ready to Use

Synthetic personas aren’t a replacement for traditional fieldwork — they’re a strategic extension of it.

In fact, many of our clients use Syntheo to:

• Validate hypotheses ahead of qualitative deep dives
• Prioritize which personas to pursue in field
• Simulate responses in low-coverage markets
• Train internal teams using AI-modeled “respondents”

Because the data is rooted in real-world logic, grounded in verified behavioral inputs, and contextually localized, it can serve as a reliable directional tool for planning and decision-making.

Why DataDiggers?

At DataDiggers, we don’t just build technology — we build it for researchers, with research logic baked in. From Brainactive to Syntheo, Modeliq, and Correlix, every tool we design helps clients bridge the gap between possible and actionable.

So if you’re working on a study that seems impossible to field — or if you're simply looking to model responses before committing budget — synthetic personas might be the key to unlocking your next breakthrough.
