LydiaBrand matching
The matching engine, explained

The thirteen questions

What each answer contributes to a match, which inputs come from the media kit instead, and the rules that no score can override.

score = fit × fit × desire × desire × history

The three angles are multiplied, so a brand that is great on one angle and poor on another ranks below a balanced one. Fit and desire count double because they are about this pairing; history is about the record. Before any scoring, gates remove what must never be shown, and only brands holding the Lydia Brand Standard, proof they pay creators at Lydia's tier, are ranked at all.

Fit

Would this creator's content and audience genuinely carry this brand?

Desire

Would this creator plausibly say yes to this brand's terms?

History

What does the record say: deals, evidence, the matchmaker's judgment?

The media kit comes first

The kit is the audience record and is treated as fact: gender split, age buckets and top countries drive the audience side of fit; follower counts set the creator's tier; the kit rate prefills questions 4 and 5. The questionnaire never asks a creator to retype what the kit already knows.

Question by question
QuestionAngleWhat it does
01Content categoriesFitThe main signal: congruence between what the creator makes and what the brand sells. The heaviest fit weight in the engine.
01bNiches (optional)Fit"Running", not "fitness": a niche pick matches the brand's own sub-niches, strengthens its category, and counts as naming it. Family and pets niches also inform the household.
02Past brand partnersHistoryFitA past deal makes that brand a warm rebook, opens its category for other brands, lifts brands sharing a specific sub-niche with a past partner, and proves a household. A deal cannot vouch for itself: the rebook only leads when the creator has an organic tie to the category.
03DeliverablesDesireMatched to what the brand's category buys; video-first categories want video.
04RatesDesireCompared with the brand's likely budget in bands, not dollars: no penalty within 2x, and a brand paying more is never penalised. Also half of the outreach gate (USD 1,000 per reel), which never affects matching.
05FloorsDesireCaps a brand paying below the floor only when the gap is large (4x or more). Pay is negotiated; the engine does not split hairs.
06Usage rightsDeal termsRecorded for the contract; not scored today. Roadmap: match heavy-usage briefs to creators who grant them.
07Usage durationDeal termsSame as question 6.
08Exclusivity?GateDesireNamed competitors are removed before scoring; category competitors get a strong caution.
09Exclusive withGateDesireSame as question 8, by brand or by category ("an activewear brand").
10Never work withGateHard exclusion by name or category word (gambling, alcohol, fast fashion, ultra-processed food, energy drinks and more), applied before scoring.
11Known forFitThe stance signal: "natural and simple" lifts organic brands and cautions energy drinks. Also adds category keywords and implies niches the creator did not click.
12Products they useFitRevealed preference, the strongest signal a creator can give: a used brand is floored high and overrides the hard caps. Same-category products give a smaller lift.
13Wish listDesireA wished-for brand is lifted only once it already fits on its own merits. Wishing never creates a match; it ranks a real one higher.
The creator card

Corrections, not questions; one click each.

  • Gender read: who the creator is, not who watches. A product made for the other gender is hard-capped, whatever the audience split.
  • Household (baby, kids, pets): read from bio, tags, niches and past deals; gates newborn, kids' and pet brands.
Lydia-side inputs

No creator effort required.

  • Deal history feeds history and the budget reference.
  • Evidence freshness down-weights stale brands; re-checked weekly.
  • The matchmaker's judgments from the training loop become bounded signals.
  • Creator dossiers: researched niches, stances and household, at work before any answers.
Rules no score can override

Dating apps and adult products are never offered. A product the creator cannot use, the wrong life stage, or near-zero category overlap caps a brand hard, unless questions 2 or 12 prove otherwise. Too few genuine fits means a shorter slate with an honest note, never filler.
