YouTube Creator Discovery for Indie Game Launches

An r/SoloDevelopment thread documented a real indie-launch pain. The OP wanted YouTubers covering games like theirs, found the manual process unworkable, and built TagRadar — a tool that takes Steam tags and surfaces matching creators. The pattern is clean and it generalizes far beyond games.

Why generic creator search fails

Searching "indie game YouTubers" on YouTube returns creators with millions of subscribers who won't cover a small launch. Influencer platforms (Modash at $99+/mo) over-target enterprise needs. The job for an indie launch is different: find 100+ creators with 1K-50K subs who already cover similar games, rank by genre overlap, draft personalized outreach.

The TagRadar shape, generalized

Input: 5-15 niche tags. Search YouTube per tag. Aggregate by channel, count tag overlap, rank. Filter by subscriber band. Output: ranked creator list with channel URLs and recent video titles per creator.

import os, requests
from collections import Counter
API_KEY = os.environ['SCAVIO_API_KEY']
H = {'x-api-key': API_KEY}

TAGS = ['roguelike', 'turn based strategy', 'pixel art', 'metroidvania']

channels = Counter()
for tag in TAGS:
    r = requests.post('https://api.scavio.dev/api/v1/youtube/search',
        headers=H, json={'query': f'{tag} game review 2026'}).json()
    for v in r.get('videos', []):
        channels[(v['channel'], v.get('channel_url'))] += 1

ranked = sorted(channels.items(), key=lambda x: -x[1])

The subscriber-band filter

Indie game launches over-target the 1K-50K subscriber band. Smaller creators are invisible; larger creators won't reply to outreach. Mid-band creators are actively building audiences and want to cover new games. The same band logic works for any niche — replace gaming with pottery, dev tutorials, or book reviews and the band stays roughly the same.

Adding the Reddit layer

Niche subreddits (r/gamedev, r/IndieGaming, r/SoloDevelopment) often discuss creators by name. A Reddit search per niche surfaces community-recommended creators that pure YouTube search misses. Add the names from Reddit to the candidate list, then verify via YouTube search.

The personalization step

For each candidate creator, fetch their channel page via the Scavio extract endpoint to get a fresh description and recent video titles. Pass to an LLM: "Draft an 80-word email to this creator referencing their two most recent videos covering roguelikes." Personalized beats generic outreach by an order of magnitude on reply rates.

Cost per launch

5 tags × 1 YouTube query = 5 Scavio credits. Plus per-candidate extract calls for the top 30 creators = 30 credits. Total: 35 credits = $0.15. The whole creator-discovery + personalization pipeline for a launch costs less than a coffee.

Why TagRadar is right and what generalizes

TagRadar wins for indie game devs because Steam tags are the right primitive for that niche. Replace Steam tags with category tags in any other niche and the same pattern applies. The bottleneck isn't the discovery — it's the personalization, which depends on having fresh creator-specific context that an extract endpoint provides cheaply.

What this is not

Not a replacement for Modash, Creator.co, or other influencer marketing platforms. Those provide audience demographics, fake- follower detection, and bulk outreach automation. The Scavio- driven script handles the discovery + first-touch outreach for indie launches that don't justify enterprise tooling.
