Reddit Mentions (Contact)

Overview

Reddit Mentions (Contact) are the person-level side of Reddit signals. When a thread names a real executive or decision-maker, and we resolve that person to a verified LinkedIn profile, a contact record ships next to the company signal.

These records are precision-first. A person ships only when the thread names a real individual (never a Reddit username) AND our resolver returns a LinkedIn profile that passes a strict confidence gate. Anyone below the gate is dropped, not guessed. Expect a small, high-trust stream - a low single-digit share of weekly volume, mostly executives in leadershipChange events.

Every contact record links to its parent company signal via data.parent_signal_id.

Available Subtypes

A contact record's signal_subtype depends on the person's role in the parent signal.

Contact subtypes - inherited event subtypes + contactMentioned

Subtype	When it applies	Description
`leadershipChange`	person is the actor	The executive joining or leaving. Carries `data.details` `{person_name, title, direction: "joins" \| "leaves"}`. The most common contact subtype
`buyingIntent`	person is the actor	A named buying champion driving an evaluation at a named company
`hiringSignal`	person is the actor	A named hiring manager behind a hiring push
`customerFeedback`	person is the actor	A self-identified employee of the company responding in-thread
`contactMentioned`	person is mentioned	A real named person relevant to the discussion but not the event's subject - an exec quoted about a deal, a board member named in a shakeup. `data.signal_category` is `event`

Actor records inherit the parent subtype's stage/category vocabularies - see the company page accordion. All records carry the same honesty labels: the stage evidence ladder and prominence (core vs aside). A years-old departure recalled in a comment ships aside + completed, not as fresh news.

Field Reference

Core Fields

Field	Type	Required	Description
`signal_id`	string (UUID)	✓	Deterministic ID derived from `(post, company, subtype, person)`. Stable across every delivery and re-run - use it as your primary key
`batch_id`	string	✓	Generation batch timestamp (UTC) - when Autobound produced the record; can differ from `detected_at` on backfilled weeks
`signal_type`	string	✓	Always `"reddit-contact"`
`signal_subtype`	string	✓	The parent event's subtype when the person is its actor; `"contactMentioned"` otherwise. See the accordion above
`signal_name`	string	✓	Always `"Reddit Mention"`
`detected_at`	string (ISO 8601)	✓	The delivery-timeline date (week-ending for weekly files). Use `data.post_date` for the conversation's real time
`association`	string	✓	Always `"contact"`
`company`	object	✓	The person's employer as the thread frames it (falls back to the parent signal's company). Compare with `contact.company_name_resolved` for where the person is now
`contact`	object	✓	The resolved person (below) - never `null` on this type

Contact Object

Field	Type	Required	Description
`full_name`	string	✓	The person's real full name as the thread discussed them. Always a full name - first-name-only mentions never ship
`job_title`	string \| null	✓	The person's current title per resolution; falls back to the title stated in the thread when resolution returns none
`company_name_resolved`	string \| null	✓	The person's current employer per resolution. This can legitimately differ from `company.name`: in the example the thread recalls Snover's Microsoft exit while resolution finds his current Harvard fellowship. Use it to catch "the exec you read about has already moved"
`linkedin_url`	string	✓	Verified LinkedIn profile URL. Always present by contract - a person our resolver cannot match to LinkedIn at high confidence is dropped, never shipped with a guess
`resolution_basis`	string	✓	Always `"named_in_post"`: the person was explicitly named in the thread text. We never resolve Reddit usernames or handles to real identities

Data Object

The data object carries the parent signal's full context - every field documented on the company page (summary, stage, prominence, timing, evidence, thread and engagement fields, comments, nsfw, content_warning, …) - plus two contact-specific fields:

Field	Type	Description
`person_context`	string	One display-ready line placing the person: name, title, employer, and whether they are the signal's subject ("the person this signal is about") or named in the discussion. Built for dropping straight into a UI or an email research panel
`parent_signal_id`	string (UUID)	The `signal_id` of the parent `reddit-company` record. Join on it to pull the company-side view of the same event - both IDs are deterministic, so the join is stable across deliveries

Quality Metadata (`_qa`)

Everything from the company page, plus three person fields:

Field	Type	Description
`person_role`	string	`actor` (the signal is about them) or `mentioned` (they appear in it). Actors are the higher-value records
`person_resolution`	string	Person-match outcome: `resolved` or `candidate` - both mean a verified LinkedIn hit passed the confidence-or-employer-corroboration gate; the label reflects the resolver's internal state, not shipping risk
`person_margin`	number \| null	The person resolver's decision margin, when it reports one

Coverage

Contact records are the rare-but-precise tail of Reddit coverage. Most Reddit conversation is pseudonymous, so only threads that name real people produce them - typically a low single-digit percentage of weekly volume, concentrated in leadershipChange. Community coverage, cadence, deduplication, and the quality machinery are identical to Reddit Mentions (Company); contacts additionally pass the person-resolution gate on top of every company-side check.
