Splice
Splice is a music creation platform offering a subscription-based library of royalty-free samples, loops, and presets, plus a rent-to-own plugin marketplace and AI-powered creation tools. Co-founded in 2013 by Steve Martocci and Matt Aimonetti, Splice has 4 million registered users and generated $142.8 million in revenue in 2025. The platform uses a credit-based model where subscribers receive monthly credits to download sounds. Splice acquired Spitfire Audio for ~$50 million in April 2025 and launched the Splice Instrument virtual instrument platform. The company has raised $164 million in funding at a ~$500 million valuation.

Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Splice launches as a lean startup offering cloud-based version control for music projects, funded by $2.75M in seed capital from Union Square Ventures and True Ventures. The product is free collaboration software with no monetization pressure, no lock-in mechanisms, and minimal organizational complexity. The founding team of Martocci and Aimonetti is mission-driven around democratizing music creation tools.
The launch of Splice Sounds transforms the company from a collaboration tool into a subscription sample marketplace, introducing the credit-based model that would define its business. The Rent-to-Own plugin program follows in 2016, creating a second recurring revenue stream. Series A and B funding totaling ~$40M fuels rapid growth to over 1 million users. Creator payouts begin scaling, but the credit expiration policy and auto-converting free trials establish early patterns of extractive design.
Splice enters an aggressive acquisition phase, absorbing Indaba Music, Capsun ProAudio, and Sample Magic to consolidate its position in the sample ecosystem. The $57.5M Series C in 2019 values the company at $285M and doubles the employee count. AI features like Similar Sounds deepen algorithmic mediation of sample discovery. The TOS 'derivative work' controversy exposes governance gaps. Creator payouts hit $15M but revenue-sharing terms remain opaque.
COVID-19 lockdowns drive a 50% spike in daily downloads and an explosion of new users, pushing the registered base past 4 million. Splice closes a $55M Series D led by Goldman Sachs at a ~$500M valuation. Creator payouts accelerate to $36M cumulative. The plan restructuring in 2021 introduces Creator and Creator+ tiers with proprietary plugins (Astra, Beatmaker, Bridge), fragmenting the subscription model and creating upsell pressure. Board member Srivastava is positioned as the eventual CEO.
Kakul Srivastava (ex-Adobe Creative Cloud, ex-GitHub) replaces founder Martocci as CEO, bringing corporate product-led-growth methodology. Glassdoor reviews document recurring holiday-season layoffs and multiple engineering reorganizations. Splice shuts down Studio, the founding collaboration platform, to focus entirely on monetization. The AI-powered Create a Stack launches. The first price increase pushes Sounds+ from $7.99 to $8.77 by late 2023, signaling more aggressive pricing to come.
Splice's subscription price increased 65% to $12.99/month, the $50 million Spitfire Audio acquisition consolidated control over both samples and virtual instruments, and the DMCA copyright strike against a YouTube lawyer reviewing Splice's terms of service drew widespread criticism. The launch of Splice Instrument gated premium content behind a separate $12.99/month tier. Revenue grew to $142.8 million, but the trajectory is clearly worsening as monetization pressure and competitive consolidation accelerate.
Alternatives
Loopmasters' subscription platform offering 4+ million royalty-free samples with DAW integration and advanced sample editing tools. Starting at $8/month with a credit-based model similar to Splice but at a lower price point. Strong genre coverage and the ability to preview and edit samples before downloading. Easy switch for sample-focused producers.
All-in-one music creation and distribution platform offering 3+ million samples, AI-powered mastering, and distribution to streaming services. Subscription bundles creation tools with release capabilities. Good alternative for producers who want samples plus distribution in one subscription, though the sample library is smaller than Splice's.
Sample marketplace offering individual pack purchases and a subscription model. Focuses on high-quality sample packs with no credit expiration on purchased content. Better for producers who prefer ownership-based purchasing over credit subscriptions, though the library is significantly smaller than Splice's.

Splice launches Rent-to-Own plugin marketplace with Serum

Splice shuts down original Studio collaboration platform
CEO Srivastava announces the closure of Splice Studio, the free collaboration feature launched in 2014 that was the company's original product. 'Although the potential of Studio to help music creators collaborate was core to our founding ideology, this feature hasn't been a focus for us since 2017,' she writes. The shutdown occurs in stages through June 2023, removing the ability to create projects, add collaborators, and eventually deleting the feature entirely.

BBB complaints later cite this as the start of pricing that 'nearly doubled in less than 2 years.'
BBB complaint documents unauthorized duplicate charges
A BBB complaint reports that Splice charged a credit card $12.99 eight times on February 26, 2024, for someone who does not have a Splice account, totaling over $100 and causing authorized payments to bounce.

The principles address artist consent, fair compensation, and responsible AI development in music creation.
Splice issues DMCA copyright strike against YouTube attorney
Splice issues a copyright strike against Miss Krystle's 'Top Music Attorney' YouTube channel for displaying sections of Splice's Terms of Service in a review video. Splice had initially sent a cease-and-desist, then escalated to a copyright strike the day after a seemingly productive phone call. The strike draws widespread backlash from the music and legal communities, with Techdirt and MusicTech covering the story critically.
Splice withdraws copyright strike after public backlash
Following widespread criticism from the music production and legal communities, Splice withdraws the copyright strike against Miss Krystle's YouTube channel. Splice CEO issues a statement claiming the company 'fundamentally supports the rights of creators to express themselves.' However, the original video and the Streisand-effect coverage had already drawn far more attention to Splice's controversial TOS than the original review did.
Splice Sounds+ price rises to $12.99, a 65% increase from 2020
Splice's entry-level Sounds+ tier reaches $12.99/month, up from $7.99 in 2020 — a 65% cumulative increase. The price hike arrives alongside BBB complaints documenting the base plan rising from $7.99 to $8.77 to $14.26 for some grandfathered plans. Users on social media describe the increase as 'price gouging' for Splice's 10-year anniversary, with one viral X post drawing widespread attention.
BBB complaint documents continued billing months after cancellation
A BBB complaint details a user charged monthly from September 2023 to June 2025 despite canceling on December 27, 2023, and being charged again December 28. The user reports zero samples downloaded throughout the period. Splice support refunds 6 recent charges ($150 total) but refuses older charges per 'business policy.' The company has 19 total BBB complaints over three years and is not BBB accredited.
Splice Creator+ tier reaches $39.99/month
The top-tier Creator+ plan is priced at $39.99/month ($399.99/year), providing 500 credits and full access to all Splice tools including Astra, Beatmaker, Bridge, and Skills. Combined with Sounds+ at $12.99 and Creator at $19.99, the tiered structure pushes heavy users toward significantly higher monthly spending compared to the original $7.99 single-tier model.
Splice acquires Spitfire Audio for ~$50 million
Splice acquires London-based virtual instrument company Spitfire Audio for a reported $50 million. The deal gives Splice control over Spitfire's prestigious libraries including BBC Symphony Orchestra, Abbey Road, and the beloved free LABS instruments.

Spitfire Audio flagship libraries launch on Splice Rent-to-Own
Three of Spitfire Audio's most popular libraries — Abbey Road Two: Iconic Strings Professional, BBC Radiophonic Workshop, and BBC Symphony Orchestra Professional — become available on Splice's Rent-to-Own platform.

Splice INSTRUMENT launches, absorbing Spitfire's free LABS
Splice launches Splice INSTRUMENT, a virtual instrument platform with 1,200+ presets built in partnership with Spitfire Audio. Both the free LABS plugin and the LABS+ subscription are discontinued, with content absorbed into INSTRUMENT.
