Platform Features
Core capabilities of Gronox
Unified Korean and U.S. schema
Normalizes EDGAR filings, XBRL, Form 4, 13F, and DART Korean filings into a single SQLite database with identical field names and units. Strategists and analysts query both markets through one connection instead of maintaining separate vendor subscriptions.
MCP-connected agent tools
Exposes 33 tools via Model Context Protocol for Claude and compatible agents, including financials, technicals, insider trades, and 13F lookups. Research teams ask natural-language questions and receive multi-source answers without manual tab-switching.
Minervini and CAN SLIM screening
Screens all 3,929 Korean listings and 7,991 U.S. listings against published trend templates and valuation criteria in a single query. Analysts no longer hand-check relative strength, volume patterns, and trend conditions across multiple tools.
Insider and 13F lookups
Retrieves SEC Form 4 insider transactions and institutional 13F holdings alongside Korean DART insider filings in one call. Portfolio managers and research leads identify accumulation or distribution patterns without cross-referencing two filing systems.
Web studio for backtesting and portfolio tracking
Provides a visual interface for screening, portfolio analysis, and strategy backtesting on normalized data. Quantitative analysts and strategists validate screening criteria and historical performance without exporting to spreadsheets.
Nightly normalized data refresh
Ingests filings and financials every night at 18:30 UTC from EDGAR, DART, and Korean exchanges. Research teams always work with current-day filings and earnings data without manual updates or lag.

Situational Fit
Fit depends on your client mix
Buy If
5Your research team spends 3+ hours per week toggling between EDGAR, DART, and separate Korean data sources to build peer comparisons or screen Korean listings. Gronox collapses that into one normalized query.
Your strategists or analysts manually assemble earnings dates, insider trades, and technicals from multiple tabs before writing research briefs. Gronox surfaces all four data types in a single agent response.
You run backtests or portfolio analysis on mixed Korean and U.S. holdings and currently hand-normalize the financials. Gronox provides a web studio with pre-normalized data.
Your team uses Claude for research workflows and wants to extend its reach beyond U.S. public filings. Gronox adds 33 MCP tools covering both markets.
You screen Korean equities using published criteria (Minervini trend template, CAN SLIM) and currently rely on manual or single-market tools. Gronox screens all 3,929 Korean listings against these templates in one call.
Skip If
5You require real-time intraday pricing or sub-minute technical updates. Gronox refreshes nightly at 18:30 UTC and is designed for end-of-day and fundamental analysis, not high-frequency trading.
Your agency focuses exclusively on U.S. equity research and has no Korean market exposure. Gronox's cross-market unification is not a differentiator for single-market workflows.
Your team does not use Claude or other MCP-compatible AI agents. Gronox is an agent-first platform; without that integration, you lose the core time-compression benefit.
Your research process relies on proprietary or premium data feeds (Bloomberg, FactSet, Refinitiv). Gronox uses only public filings and open data sources, which may not meet institutional compliance or data-freshness requirements.
Your team is smaller than three analysts and does not conduct systematic screening or cross-market research. The per-seat cost and onboarding friction exceed the time savings for ad-hoc, single-user workflows.
Bottom Line
Gronox normalizes Korean and U.S. financial filings, technicals, and insider data into a unified schema accessible via Claude and other AI agents, eliminating the need to toggle between EDGAR, DART, and separate Korean data vendors. Investment research agencies, quantitative analysis firms, and financial data providers benefit most by adopting it internally to compress research workflows from 30 minutes across four tabs into single-line agent queries. The platform covers 11,920 listed companies, refreshes nightly, and includes screening tools (Minervini, CAN SLIM), 13F lookups, and a web studio for backtesting and portfolio tracking.
Reality Check
Gronox is purpose-built for cross-market equity research and adds no value to agencies that focus exclusively on U.S. equities or do not conduct fundamental analysis. Adoption requires team familiarity with MCP-connected AI agents; agencies without Claude or similar agent workflows will see minimal ROI.

Why this category matters
The commercial case before the tooling.
Core concepts
The mental model you need to price and scope the work.
- Modeling Debt CeilingConcept
Modeling debt is the gap between the raw data a BI platform can reach and the governed metric definitions a client will actually trust. Every unmodeled metric (a disputed conversion rate, a pipeline number finance rejects) gets re-derived by hand each reporting cycle, so delivery hours scale with client count instead of staying flat. The ceiling is the point where hand-rework consumes the margin a retainer was priced to protect. A B2B paid media team that cannot connect ad platform conversions to CRM opportunity records produces a pipeline figure finance will not accept, and the agency absorbs the rework every month. Platforms differ in how much modeling they force up front: Sigma Computing queries warehouse data live with governance at the source, Knowi skips ETL entirely across 70-plus sources, and ClicData bundles warehouse and transformation into one environment. The framework says: price the modeling pass before you price the dashboard.
- The Reporting Substrate LayerConcept
The Reporting Substrate Layer is the data foundation beneath every dashboard an agency delivers: source connections, transformation logic, metric definitions, and refresh cadence. Agencies that treat BI tools as the visible layer alone sell a commodity; those that own the substrate turn reporting into a retainer that is expensive for clients to replicate. The category description makes this explicit: the platform alone does not establish offer value, because data modeling, source reliability, and analyst review determine delivery cost and usefulness. A concrete example is the attribution gap described in PPC pipeline reporting, where ad platform conversion data is not connected to CRM opportunity records, leaving finance teams unable to trust the pipeline number. Closing that gap requires substrate work, not a new chart. Agencies that build the substrate first can price on decision cadence and governance rather than dashboard count, and they can defend the retainer when a client considers bringing analytics in-house.
- The Analyst Substitution TestConcept
The Analyst Substitution Test asks one question before pricing a BI retainer: how many hours of human analyst work does this dashboard actually replace each month? A platform that surfaces a number a client's ops lead already pulls by hand displaces almost nothing, so the fee has to be justified by something else. A platform that collapses a recurring Monday morning data pull, reconciliation, and commentary cycle into a reviewed view displaces real labor, and that displaced labor is the ceiling on what the retainer can carry. Run the test on a defined dataset and reporting workflow before quoting fees. A pipeline attribution number finance will accept, for instance, requires connecting ad platform conversion data to CRM opportunity records, which is analyst work whether a person or a platform does it. Tools like Knowi, Sigma Computing, and Qlik differ less in chart quality than in how much of that recurring work they absorb.
Decision and risk
How to judge the fit, and the ways it goes wrong.
- BI Tools Rule: Price the Reporting Workflow Before the LicenseEvaluation Rule
Model the full reporting workflow on a defined client dataset before signing a BI license or quoting a retainer, because the platform is the cheapest line item in the delivery.
- When Client Data Lives in Six Systems, Model the Join Before Buying DashboardsEvaluation Rule
Prove the data model on one client's real sources before committing to any BI platform or embedded analytics retainer.
- Managed Analytics Retainer vs Client Self-Serve LicenseDecision Framework
IF a client's reporting need is stable, decision-relevant, and tied to a recurring meeting or budget review, THEN package the BI platform as a managed retainer where the agency owns modeling, source reliability, and analyst review. IF the client already has an internal data owner, a warehouse, and a defined question backlog, THEN resell seats or an embedded license and let their team drive the tool while the agency scopes and governs the data layer.

Frequently Asked Questions
Answers about pricing, setup, implementation
Gronox normalizes Korean and U.S. financial filings, technicals, and insider data into a unified schema accessible via Claude and other MCP-compatible AI agents. It covers 11,920 listed companies (3,929 Korean, 7,991 U.S.), screens Korean equities using published criteria like Minervini and CAN SLIM, retrieves insider trades from SEC Form 4 and DART, queries 13F institutional holdings, and provides a web studio for portfolio analysis and backtesting. All data is sourced from primary authorities (EDGAR, DART, Korean exchanges) and refreshed nightly.
Starter plan is $10 per month (or $8.40 per month billed annually) and includes 300 tool calls per day, all Korean and U.S. financials and filings, technical indicators, and full historical data. Pro plan is $30 per month (or $25.20 per month billed annually) and adds 5,000 tool calls per day, five strategy screeners, and live insider and 13F lookups. Enterprise plans are custom-priced and include 50,000 tool calls per day plus dedicated onboarding. All plans include a 7-day free trial.
Research analysts and strategists compress multi-source research workflows into single-line agent queries, eliminating tab-switching between EDGAR, DART, and Korean data vendors. Portfolio managers and quantitative analysts use the web studio to backtest screening criteria and validate peer comparisons without exporting to spreadsheets. Account executives and business development leads use the screener to identify investment themes and Korean market opportunities for client pitches. Founders and operations teams reduce research tool sprawl by consolidating Korean and U.S. data into one platform.
A research analyst conducting cross-market fundamental analysis saves 3 to 5 hours per week by eliminating manual data assembly across EDGAR, DART, and separate Korean sources. An analyst who screens Korean equities using published criteria saves 2 to 3 hours per week by querying all 3,929 listings at once instead of using single-market tools. Portfolio managers backtesting strategies save 4 to 6 hours per week by using the web studio instead of exporting and normalizing data in spreadsheets. Savings scale with team size and research frequency.
Yes. Gronox exposes 33 tools via Model Context Protocol (MCP), so Claude can query financials, technicals, insider trades, 13F holdings, and screening results directly. You connect your Claude API key to Gronox and ask natural-language questions; Claude retrieves data from the normalized schema without you manually toggling between platforms.
Initial setup takes 1 to 2 hours: obtain an API key, connect Claude, and run one test query. Team adoption takes 1 to 2 weeks as analysts replace manual research workflows with agent queries. No data migration or infrastructure changes are required; Gronox is a drop-in data layer for existing Claude workflows.
Yes. Gronox covers 1,354 Korean ETFs alongside individual listings, so you can screen and analyze ETF holdings, technicals, and performance within the same platform.
Gronox does not store user data, watchlists, or screening results on its servers. All data remains in your Claude workspace or local environment. Cancellation removes your API access; no data is retained or deleted by Gronox.
