IssueDescriptionSignals ImpactedEst. Resolution
SEC filing signal accuracy — incorrect classifications and hallucinated detailsLLM extraction workflow can misclassify signal subtypes (e.g., labeling a capex decrease as capexIncrease, or intangible asset impairment as goodwillImpairment) and generate speculative detail text not directly supported by the filing. Additionally, the LLM sometimes extracts only a single sentence of evidence, which can lose important context such as directional changes (increase vs decrease). We are implementing a validation layer that cross-checks generated signals against the source filing, tighter classification rules for directional and categorical signals, and more comprehensive excerpt extraction.10k, 10q, 8k, 20f, 6kFeb 28
Job title normalizationImproving disambiguation for ambiguous titles like "CMO" (Chief Marketing Officer vs Chief Medical Officer) based on company context and industry.10k, 10q, 8k, 20f, 6k, earnings-transcriptsFeb 6
LinkedIn signals could surface more useful contextPosts currently only have basic tags; need richer metadata to create more useful signals. Sentiment, relationship (like commenter to poster), etc.linkedin-post-company, linkedin-post-contact, linkedin-comment-contactFeb 6
Schema inconsistenciesSome fields have similar names with subtle differences (e.g., relevance vs sales_relevance). API vs Signal Database payloads have structural differences. Refer to signal-specific schema docs.All signalsOngoing
