Stop guessing which creators actually run sponsored posts.
Stumil ranks skincare creators from verified sponsorship signals — with estimated price ranges and competitor-overlap flags you can check yourself. Every score is computed in code, source-linked, and labeled observed or estimate.

From campaign brief to evidence-backed shortlist in three steps.
No black-box matching: you see the inputs, the scores, and the sources.
Set the campaign constraints
Tell us the campaign constraints — niche, platform, market, budget band, competitors to flag. We only work with inputs the engine can actually verify or label.
Review creators by fit, not follower count
Each creator gets per-campaign sub-scores, a plain-language “why”, a price range, and explicit flags for overlap or missing data.

Discovery tools give you names. Stumil gives you evidence you can defend.
The product difference is simple: we treat sponsorship history and price uncertainty as first-class data, not marketing copy.
Looks relevant, hard to trust
- Global popularity or audience tags masquerade as campaign fit.
- Sponsorship claims are inferred, stale, or missing source links.
- Single “rate” numbers hide uncertainty and method.
- Competitor overlap is buried inside opaque scores.
- Missing data quietly inflates confidence.
Evidence-first, inspectable, honest
- Per-campaign fit score with six sub-scores and a readable rationale.
- 1,162 detected sponsorships across 52 brands, every one dated and source-linked — each labeled high (1,090) or medium (72) confidence, verified by a 50-post hand-check at 0.96 precision (bar: 0.85).
- Prices render as ranges labeled estimate until observed deals exist.
- Competitor overlap is a separate flag, never blended into fit.
- Data gaps cap scores and are shown as “not available”.
The brief is the product. The dashboard is the same evidence, operationalized.
Give marketers a concrete output they can review in minutes and forward without rewriting.
- Competitor sponsors we can see — with confidence wording and source links.
- Shortlisted creators with “why” — per-campaign fit, not a generic influencer score.
- Price ranges, labeled honestly — estimates stay estimates until replies become observed data.
- Print/share ready — same source of truth for outreach, review, and follow-up logging.

Where does the data come from?
From public sponsorship signals (such as paid-partnership labels, tags, discount codes, and other detectable markers) combined with a curated creator dataset for the supported niche. Every surfaced claim includes its source, method, and as-of date where applicable. Current coverage: 3,310 skincare creators (2,937 Instagram, 373 TikTok) across 8 sub-niches, with 1,162 detected sponsorships across 52 brands.
Creators are tiered by evidence quality: 2,888 Tier A · 334 B · 88 C. Every Tier A creator carries US-audience share data; where audience data is missing we show “not available” and cap the score rather than guess. Tier C is a documented gap we’re filling — we don’t pad it.
Source: v2 dataset (creator tier labels) · as of 12 Nov 2026.
Are the prices quotes or guarantees?
No. Prices are estimated ranges labeled as estimate. When real replies or observed deal data are recorded, the estimate can move toward observed values. Observed and estimated figures are never presented as the same thing.
How is this different from “AI-powered creator discovery”?
Stumil computes scores and flags in code from defined inputs. Language generation is used to explain results, not to invent numbers or sources. If data is missing, the UI shows “not available” and caps confidence where required.
Why only skincare on Instagram in US/UK right now?
Because narrow scope is how we keep precision high. Expanding niche, platform, or market requires new evidence quality checks and a deliberate spec revision—not just a toggle.
Do you send outreach or manage creators for us?
No. Stumil produces the evidence-backed shortlist and brief. You decide who to contact and send outreach yourself. No auto-DMs, no contracting, no media buying.
How current is the data?
Every figure carries an as-of date. In the current dataset, 643 of 1,162 detections are within the last 90 days, and each detection links to the post it came from.
