Less filing noise, more useful questions
A research workflow, not a raw alert feed.
Fenris is built for investors who want to know which insider buying deserves attention, why it may matter and what to check next.
Audit the past
Check forward outcomes with split-aware price handling, so old filings do not create fantasy performance.
Generate hypotheses
Turn clusters, unusual buys and historical echoes into structured research ideas with evidence and caveats.
Keep the trail clean
Save tickers, revisit cases and avoid scanning the same low-value noise across multiple screens.
Not another alert feed. A full research loop.
Fenris does not stop at "an insider bought". It helps users move from signal to context, hypothesis, track record and rules.
01 / Signal triage
Start from one useful brief, then scan the feed.
Fenris gives the user a daily candidate with amount, role and reason to open it. The alert feed stays clean: one search box, hidden filters and no wall of decorative tags.
- Daily briefing for the most relevant recent signal.
- Recent filings sorted for review, not noise.
- Search and filters only when the user needs them.
02 / Hypothesis engine
The Lab turns filings into questions you can test.
Users can compare past events, save hypotheses and build a backlog of ideas that mature when enough data exists.
- Query historical cases with clear filters.
- Save hypotheses like clusters, role changes or drawdowns.
- Keep research ideas separate from raw notifications.
03 / Company evidence
Open a ticker and see why the activity matters.
Company panels connect concentration, insiders, audited sample size and historical 9M performance before a ticker earns more attention.
- High-level activity profile before detailed research.
- Audited samples and 9M performance visible in context.
- Chart, RSI and moving averages inside the same flow.
04 / Insider track record
Follow the people, not only the tickers.
Fenris can show which insiders repeatedly buy, which companies appear in their history and how prior purchases behaved when enough sample exists.
- Flow, operations and positive 9M history in one profile.
- Bought tickers linked to the insider's activity.
- Recent transactions ready for deeper review.
05 / Automation without spam
Let users define what deserves an interruption.
Push rules start simple: ticker, role and minimum amount. More exact constraints stay available when a serious user needs them.
- Create objective rules by ticker, role and amount.
- Expose advanced filters without overwhelming the account page.
- Pause or delete rules cleanly when priorities change.
The Lab is the advantage
Fenris is strongest when it turns activity into testable ideas.
Alerts tell you something happened. The Lab helps decide whether it belongs in your research queue.
Hypotheses
A structured reason why a filing could matter, what evidence supports it and what would invalidate it.
Patterns
Repeated behaviors across insiders, tickers or sectors that may deserve a focused review.
Drafts
Research notes that can mature from raw signal to reviewed case without turning the app into a noisy social feed.
