👤 Jason Grishkoff (Ex-Googler on compensation team, self-taught coder who ran blog Indie Shuffle; knew curators and artists, seeded both sides solo.)🌐 siteindieshuffle.comLinkedIn
Buried under 300 song submissions a day, a music blogger made artists pay a small fee for a guaranteed listen.
Will it work? · our read
Owned both sides. He didn't invent music promotion; he was the gatekeeper who monetized his own inbox. The moat is his blogger network, not the code. Copy the code, not the relationships.
01How the money moves
Artist buys credits, about $1 each
→
Sends a song to a curator, who must listen 60s+ and reply or the credit refunds
→
Curator earns $0.50; SubmitHub keeps the spread on every submission

Grishkoff manually emailed about 1,000 blogs over four months to recruit the first curators, then ran it solo as the only developer.
About $50K/mo self-reported (Indie Hackers, roughly 2016-2018); likely higher now but not first-party confirmed. Growjo guesses about $5M/yr (unverified).

Indie Hackers podcast #001 — founder states about $46K/mo, origin storyIndie Hackers — SubmitHub self-reported MRR (about $55K/mo)Ari's Take — interview with founder Jason GrishkoffSubmitHub blog — curator pricing and credit modelGrowjo — third-party revenue estimate, unverified
Revenue is self-reported, not audited. Grishkoff stated about $46K/mo at eight months (Indie Hackers, around 2016) and the Indie Hackers page lists about $55K/mo MRR, undated. These figures are old; with about 30M submissions by 2022, current revenue is likely higher, and Growjo estimates about $5M/yr (2026), but that is an unverified third-party guess, not first-party. Solo, bootstrapped and no-VC is well documented (he manually recruited about 1,000 curators over four months). The 'dies' scenario is our read, backed by recurring 'is it a scam?' complaints and low approval rates; the company is still thriving, so treat it as a risk, not a prediction. His X handle was not confirmed, so founder links use only verified pages (SubmitHub, Indie Shuffle, LinkedIn). We never score you.
