What Cosign does

Cosign is a US-based proptech company that operates a third-party guarantor platform enabling renters without traditional cosigners to qualify for housing while helping property owners increase occupancy rates. The company's core product is a dynamic risk model that evaluates payment behavior as an alternative to relying solely on credit scores, allowing property managers to approve applicants who would otherwise be rejected under conventional qualification standards. During a yearlong beta ending in November 2025, the platform achieved a 90% approval rate and zero churn among property partners; it subsequently launched nationwide and reports an average 8% occupancy lift for property partners as of March 2026.

Cosign distributes its platform through a direct field sales motion targeting property owners and managers, with a team of more than 25 real estate professionals covering all 50 US states and a stated 2030 goal of enrolling 5 million units and serving 10 million families. Revenue is generated via subscription-recurring fees from property partners for guarantor services integrated into their approval workflows. Fastest-growing markets include Texas, California, Georgia, and Florida, with recent expansions into secondary Sun Belt markets such as Valdosta, Myrtle Beach, Evans, and Murfreesboro. The company was founded in November 2024, is based in Culver City, and has disclosed only $200,000 in early-stage funding from Zrosk Investment Management, with no API, public SDK, or third-party integrations disclosed.

Core offering

Cosign operates a DeFi-powered marketplace platform that lets music fans financially support emerging musicians by paying a one-time entry fee to 'cosign' them. As cosigned artists accumulate streaming growth, fans earn cash payouts plus exclusive perks including early access to music, 10% merchandise discounts, 10% event and tour discounts, and chances to win lifetime backstage passes. Built on decentralized finance (DeFi) infrastructure, the platform aims to bypass traditional music industry gatekeepers by enabling artists to retain all value beyond initial investments while giving fans direct involvement in artist success.

Broad incumbents

• Patreon: Patreon is the dominant creator-monetization platform, letting fans pay creators directly for membership perks and content. Cosign mirrors Patreon's fan-pays-creator logic but adds DeFi-style investment upside, competing for the same creator-economy wallet share.
• DistroKid: DistroKid is the largest DIY music distribution platform, serving independent artists with release and royalty tools. Cosign competes for the same independent/emerging artist segment that DistroKid serves, but with investment-based fan engagement rather than distribution infrastructure.

Emerging players

• Koji: Koji is a creator-economy platform that powers digital goods, tip jars, and merch tools for creators across music and other categories. It is comparable to Cosign as an emerging fan-monetization infrastructure for independent creators, though broader than music.
• Stem Player / Gareth Emery's Stem: Stem (and the Stem Player hardware) is a music-artist platform that uses blockchain for direct artist-fan revenue splits. It is adjacent to Cosign in offering crypto-enabled artist monetization and direct fan-to-artist economics.
• Audius: Audius is a decentralized music streaming platform with a crypto-token economy for artists and listeners. It overlaps with Cosign on the music-and-crypto intersection but centers on streaming distribution rather than fan investment.

Direct peers

• Royal: Royal is a music-NFT and fan-investment platform that lets fans buy ownership shares in songs and earn royalties as streams grow. It is the most direct competitor to Cosign's artist-endorsement-and-dividend model, with a significantly larger capital base and catalog of established artists.
• AnotherBlock: AnotherBlock tokenizes royalty rights to songs so fans can buy fractions of streaming income. It is comparable to Cosign in offering financial upside to music fans, though it focuses on catalog rights of established tracks rather than emerging-artist endorsement.
• Sound.xyz: Sound.xyz is a music NFT platform where artists release limited-edition tracks as collectibles for fans. Like Cosign, it merges fan engagement with on-chain investment mechanics in the music category, though its primary unit is the song rather than the artist relationship.
• Catalog (catalog.works): Catalog is an NFT marketplace focused on 1/1 music collectibles and tokenized rights. It overlaps with Cosign in the music-NFT investment category and in using crypto mechanics to let fans participate in artist upside.
• Corite: Corite is a fan-investment platform for music where fans fund emerging artists in exchange for a share of streaming royalties. Its funding-for-royalties model and emerging-artist focus closely mirror Cosign's fan-artist investment thesis.
