Introducing Fathomer: The AI Research Agent for Analyzing Open-Ended Data in Fathom
Fathomer, Fathom’s new AI research agent, analyzes open-ended data using verified coded data. Transparent, accurate, and built for market researchers.
Market researchers and customer insights teams are being asked to deliver deeper insight from more data, in less time, with greater strategic impact. Open-ended responses, customer stories, multi-wave trackers, online reviews, interview transcripts, mixed methodology studies. Each dataset contains the nuance leaders need, but getting from raw text to strategic clarity has often required long cycles of coding, synthesis, and manual reporting.
Fathom already solved the hardest part of that challenge by combining human oversight with advanced AI to create and apply nuanced thematic coding to open-ended data and customer feedback with unprecedented accuracy and speed. Now we are unlocking the next layer of value.
Meet Fathomer, Fathom’s agentic research agent.
Fathomer is an advanced AI research assistant that uses agentic technology to transform your coded open-ended data, verbatims, quant fields, segments, and sentiment into a living research engine. Whenever a question arises, you can ask Fathomer to explore your data, generate hypotheses, understand drivers, compare segments, and synthesize report-ready insights. It accelerates open-ended and mixed methodology analysis with full transparency at every step.
This is research that moves as fast as you do while staying grounded in high quality data.
What Makes Fathomer Different From Other AI Research Tools
Fathomer offers a new level of capability for market researchers by combining accuracy, transparency, and explainability. It is built specifically for open-ended data analysis inside Fathom and is not a chat-style tool that guesses or improvises.
Fathomer stands out because it provides:
Agentic research workflows rather than simple chat interactions
Analysis grounded in verified coded-data, always human-reviewed
Transparent step-by-step reasoning and research plans
Cross-survey and multi-wave analysis, as well as in survey queries
Supports complex and strategic research questions, not just chat interface
Rich insight built on Fathom’s industry leading text analytics
This combination gives researchers a powerful, defensible way to move from questions to insight with clarity.
Why Fathomer Matters for Market Researchers and Insights Teams
Fathomer is built directly on what Fathom does best: accurate and nuanced coding that reflects real human meaning. Because it relies entirely on verified data, it does not hallucinate insights or construct narratives that are not supported by evidence. Every step is visible, guided, and grounded.
Your research question drives the process. Your context shapes the direction. Fathomer shows its work so you can understand exactly how each conclusion was reached and refine the plan along the way. It enhances researcher expertise rather than pretending to replace it.
This turns your Fathom workspace into an always on repository for ongoing exploration and mixed method insight. It reduces the time from question to answer by more than twenty times and expands what researchers can reasonably analyze within a single project or across many.
Five Ways Fathomer Accelerates Analysis of Open-Ended & Mixed Method Data
Longitudinal analysis
Fathomer examines how themes, sentiment, and drivers shift over time. It brings structure to multi-wave studies and tracking programs by identifying meaningful changes, emerging issues, and signal inside large volumes of feedback.
Drivers analysis
It uncovers which themes and attributes most influence an outcome such as satisfaction, NPS, likelihood to adopt, time on platform, or churn risk. Fathomer clarifies what moves the metric and helps researchers focus on what matters most.
Persona development
Fathomer draws from multiple questions or surveys to outline coherent personas rooted in actual data. It highlights characteristics, motivations, needs, and tensions and surfaces what distinguishes one group from another.
Theme combinations and co-occurrence
Many insights live in the relationships between ideas. Fathomer identifies which themes appear together, which clusters are common within or across segments, and which combinations predict specific outcomes.
Cross survey and multi survey synthesis
When several studies touch on the same space, insight becomes richer when the data is viewed together. Fathomer connects findings across surveys, segments, and time periods to reveal broader patterns and opportunities.
Across all of these applications, Fathomer generates draft reports, curated insights, charts and visualizations, and next step research recommendations that help teams move from questions to decisions with clarity and speed.
How Fathomer Uses Agentic AI to Accelerate Open-Ended Data Analysis
Fathomer begins by understanding the question you want to explore. You can speak in the language researchers actually use. A strategic question, a hypothesis, or a broad area of curiosity. Fathomer interprets the intent and builds a research plan that aligns with what you care about.
Fathomer is far more than a chatbot to chat with your data. It is an advanced research agent capable of running multi-step analysis. This means you can ask far more complex research questions and receive far more thorough and sophisticated results than with standard chat tools.
Fathomer clarifies the context you provide, checks its assumptions, and breaks your question into a sequence of analytical steps. It draws from every data source in your Fathom workspace, from the raw text of verbatims and customer feedback to the detailed thematic and sentiment codes Fathom has applied, plus all quantitative variables including demographics, attitudinal measures, and behavioral metadata. It can dive deep on a single survey or synthesize insights across long-running trackers.
From there, Fathomer moves through the analysis step by step. You can view the plan, guide the direction, and confirm the focus. If something needs refinement, you can adjust it. If the context shifts, Fathomer shifts with you. The interplay between researcher and agent makes complex analysis faster and more reliable while keeping the human in control.
Fathomer produces synthesized insight that ties directly back to the data. It can generate draft reports, outline next research steps, summarize findings, and support the strategic decisions that follow. Everything is visible, explainable, and grounded in the high quality data inside your Fathom workspace.
How Fathomer Protects Data Quality and Avoids Hallucinated Insights
Fathomer stays within the boundaries of research. It does not fabricate explanations or extend beyond the evidence in your data. It does not generate strategy without support and it does not replace researchers or override their judgment. It will not pull external context unless you provide it.
Instead, it enhances the work researchers already do by giving them a more powerful way to explore, validate, and communicate insight. Researchers define the goal and maintain control, in line with Fathom’s Ethical Application and Development of AI policy. Fathomer provides the analytical heavy lifting and creates the connective tissue across datasets.
As part of the Fathom platform, Fathomer is adherent to requirements for our SOC2 certification and GDPR compliance. Your data remains secure and private, and you maintain full control over how it’s used.
A New Layer of Value Inside Fathom’s Text Analytics Platform
Fathomer is available today for all current Fathom customers and will be available to all new customers beginning in 2026. It adds a new layer of value for teams already using Fathom for high quality text analysis and coding of open-ended feedback. The data you have in Fathom becomes massively more valuable the moment Fathomer is turned on.
Every dataset becomes accessible for future questions. Every survey becomes a building block for broader understanding. Every piece of coded data contributes to a richer, more flexible research engine that evolves as your organization’s questions evolve.
