Rumblefish (HFA)

Rumblefish is a rights management and music licensing company based in Portland, Oregon, now operating as part of the Harry Fox Agency (HFA) under SESAC Music Group. Founded in 1996 by Paul Anthony Troiano, the company originally focused on licensing music for online video and YouTube creators. SESAC acquired Rumblefish in 2014 for approximately $27 million. In 2015, SESAC merged Rumblefish with HFA's Slingshot division, creating a combined rights management platform. As of 2026, HFA/Rumblefish serves over 46,000 music publishing clients and covers more than 1.8 million musical works.

How Rumblefish Works

Rumblefish operates differently from most companies in this directory. It is not a sync licensing agency that pitches independent artists' music to supervisors. Instead, it is a B2B rights management and licensing infrastructure provider that sits between rights holders (publishers, labels) and music users (platforms, apps, social media companies).

The company provides several core services:

1. Mechanical licensing: Through HFA, the company issues mechanical licenses for physical and digital distribution, including CDs, downloads, ringtones, and streaming.
2. Micro-licensing: Rumblefish handles high-volume, low-value licensing for platforms that use music at scale (social media, karaoke, background music services).
3. Content ID administration: The company manages Content ID claims and revenue collection on YouTube and other platforms for rights holders.
4. Sync and rights administration: Rumblefish processes synchronization licenses for digital platforms and manages the associated royalty distribution.
5. Data and royalty management: The platform processes royalty data, matches usage to rights holders, and distributes payments.

In June 2025, Rumblefish signed a deal with ByteDance to provide music data, licensing, and royalty management services for TikTok and CapCut. This agreement means Rumblefish acts as the licensing bridge between music publishers and two of the world's largest short-form video platforms.

Who Rumblefish Is For

Rumblefish serves two distinct audiences:

For publishers and labels: HFA/Rumblefish provides licensing administration, royalty collection, and rights management at scale. If you are a music publisher with a catalog that generates mechanical royalties, sync fees, or digital performance revenue, HFA/Rumblefish can handle the licensing infrastructure. The platform's reach to over 46,000 publishing clients means it has the largest licensing footprint in the United States for mechanical rights.

For music tech platforms: Companies that use music at scale (social media apps, streaming services, karaoke platforms, AR/VR companies, AI music companies) can use Rumblefish as a one-stop licensing partner. Instead of negotiating individual deals with thousands of publishers, platforms can license through Rumblefish and access a massive catalog of pre-cleared works.

Individual artists do not typically submit music directly to Rumblefish. Instead, artists benefit indirectly when their publisher or label partners with HFA/Rumblefish for rights administration.

Key Benefits

• Scale: With 46,000+ publishing clients and 1.8 million+ works covered, HFA/Rumblefish has the largest licensing footprint among US mechanical rights administrators.
• Platform deals: The ByteDance/TikTok deal means publishers working with HFA/Rumblefish can monetize their catalog on TikTok and CapCut without negotiating separately.
• Integrated services: The merger of HFA and Rumblefish under SESAC means publishers can get mechanical licensing, sync administration, Content ID management, and royalty processing from a single provider.
• SESAC backing: As part of SESAC Music Group, Rumblefish has the financial stability and industry relationships of a major music rights organization.
• Technology infrastructure: Rumblefish's RADKey system and data processing tools handle massive-scale licensing and royalty distribution efficiently.

Potential Drawbacks and Things to Consider

• Not a direct sync pitching service: Rumblefish does not pitch your music to music supervisors or secure creative placements. If you want someone actively pitching your tracks for film and TV, look at sync licensing agencies like Crucial Music or Bodega Sync instead.
• B2B focus: The platform is designed for publishers, labels, and music tech companies. Individual artists cannot submit music directly for sync representation.
• SESAC ownership: Rumblefish is owned by SESAC, which is itself a PRO. If you are affiliated with ASCAP or BMI, there is no direct conflict, but some publishers prefer to work with rights administrators that are not owned by a competing PRO.
• Complexity of royalty statements: According to industry reporting, royalty statements from media music rights deals can be opaque. Even in 2025, companies in this space still receive generic rolled-up income statements rather than detailed per-use breakdowns.
• Website transition: Rumblefish.com now redirects to HarryFox.com. All services and information are consolidated under the HFA brand.
