Test decisions with synthetic people before you test them with real ones.
Ereace connects real human signals, synthetic people and the systems built around them, so teams can understand, test and act on human behavior before decisions reach the real world.
Synthetic people with psychological depth, conditioned by country and grounded in real demographic data.
Synthetic pre-research for qualitative studies.
Rehearsal of high-stakes conversations.
One engine. Three ways to apply it.
Find out what people think, need, reject or value before you invest in fieldwork.
Synthetic interviews by segment, with drivers, barriers and needs, and every quote traceable to its transcript.
Put products, journeys, messages and conversational agents in front of people who don't always follow the happy path.
Direct access to the engine: dashboard, CLI, Python SDK and HTTP API, plus public datasets on Hugging Face.
Practice the conversations where what the other person thinks matters, not just the scenario you prepared.
Rehearse negotiations and high-stakes decisions against synthetic decision-makers with their own profile and priorities.
The Ereace system
A synthetic simulation core, StrataSynth, with applications built on it, and the infrastructure layers that feed and extend the system.
Human simulation

StrataSynth
AvailableSimulation engine for synthetic humans. Model how people think, decide and react — before you go to market. Test products, messages and research hypotheses at scale without waiting for real respondents.
- Structured psychological profiles (beliefs, emotions, decision patterns)
- 8 countries · public datasets on Hugging Face (CC BY 4.0)
- Access via dashboard, CLI, Python SDK and HTTP API

QualiSynth
Now launchingSynthetic pre-research for qualitative research agencies, freelancers and in-house insight teams. Test guides, messages and segments with synthetic interviews before fieldwork.
- Synthetic interviews with psychographic panels
- Every quote traceable to its transcript
- Automated insight generation and thematic analysis
- Agency-grade deliverables (PPTX, PDF, Excel via InsightRender)
Human intelligence infrastructure
Layers that capture human signals, read audiences in real time and give AI agents memory, feeding and extending the system.
AI-powered forms that capture, qualify, validate and recover leads with built-in intelligence.
Real-time audience intelligence for events, product launches and live feedback.
Memory, continuity and behavioral evolution layer for AI agents.
From real behavior to simulated behavior.
- 01Capture
Collect real human signals.
- 02Model
Build synthetic people with identity and structured behavior.
- 03Simulate
Put them in front of products, messages, systems and conversations.
- 04Compare
Contrast synthetic with real when it matters.
- 05Learn
Turn what you learn into the next hypothesis.
Real → synthetic → real → synthetic.
We build the tools we couldn't find.
Hi, I'm Ruly Altamirano, founder of Ereace.
Ereace was created from a simple principle: instead of adapting to limited tools, we build the infrastructure we actually need — then reuse it across everything we create. Every product in the ecosystem exists because no existing solution solved the problem well enough.
HexaForms wasn't started as a "form product". It exists because capture layers without intelligence lose value at every step. QualiSynth exists because research that takes weeks by the time it's done is already outdated. StrataSynth exists because real respondents are expensive, slow and can't be used to test every hypothesis.
These products aren't bets placed in different directions. They're the same problem approached from different angles — and connected into one system.
Infrastructure before interface.
StrataSynth is the engine: synthetic people with psychological depth, conditioned by country and grounded in real demographic data.
QualiSynth applies it to research: synthetic pre-research before you fund fieldwork.
ArenaSynth applies it to practice: rehearse high-stakes conversations before they happen.
HexaForms, InsightPulse and LuminoraCore are other layers of the ecosystem: capture, audience signals and memory for AI agents.
"One engine. Multiple applications."
Ventures only. No consulting.
We partner to build AI-first products — ideally where you bring distribution, domain leverage, or proprietary data. We bring the architecture, the simulation infrastructure, and the research capabilities.
- • Repeatable SaaS (multi-tenant), not bespoke software
- • Clear outcome and clear GTM path (yours or jointly)
- • AI + cloud provides real leverage, not cosmetic "AI sprinkles"
- • Distribution, domain expertise, or data you bring to the table
- • Hourly development or outsourcing
- • "Build this for us" engagements
- • Staff augmentation or contractor roles
- • Traditional consulting

Short and direct. Only if it's product-based.

Common questions about Ereace and how we work.
Important decisions happen between people.
Ereace builds the infrastructure to simulate those interactions before they happen.
