What Iobuilders does
Iobuilders (legal name: IO Builders Blockchain Technologies & Ventures) is a Madrid-based, privately held enterprise blockchain technology company founded in 2018. It develops and deploys distributed ledger technology (DLT) solutions for regulated financial institutions, large corporations, and public-sector organizations, with operational presence in Spain, the UK (post-Adhara merger), and Latin America via LacChain, and a stated team of 80+ enterprise architects, blockchain specialists, and legal experts.
The company's product portfolio centers on two proprietary platforms: Asseto, an end-to-end tokenization platform available in two variants — Asseto Financial Digital Assets (production-ready for issuance, registry, lifecycle management, trading, and settlement of tokenized instruments such as equity, debt, funds, loans, deposit tokens, and stablecoins across any DLT network) and Asseto Non-Financial Digital Assets (an NFT platform for loyalty, ticketing, ESG, and collectibles supporting ERC-721/1155/Dynamic NFTs); and Naryo, an open-source, self-hosted, multichain event listener that captures and broadcasts on-chain events to APIs, queues, or databases across EVM and Hedera networks. The platform is blockchain-agnostic across Ethereum, Hedera Hashgraph, Hyperledger Besu, Solana, and others, and is designed for full deployment inside the institution's own environment with API-first integration.
Iobuilders generates revenue through three streams: (1) professional services including strategic blockchain advisory, technology assessment, regulatory advisory, white-paper production, and DLT training; (2) Asseto platform licensing and configuration-driven deployment (subscription/recurring plus licensing economics) sold via multi-year enterprise contracts; and (3) deep-tech and innovation services covering DLT protocol development, Web3 tooling, and infrastructure. Go-to-market is enterprise field sales complemented by strategic co-selling arrangements (notably with Hashgraph via HashSphere from June 2026 onward) and integration-led distribution through partners such as Allfunds. The company does not publicly disclose pricing or revenue.

Iobuilders competitors and assessment
Company assessmentBroad incumbents
- Fireblocks: Fireblocks offers digital-asset custody, settlement, and tokenization infrastructure for institutions; a stated ioBuilders partner and broad incumbent competing across the asset-management and trading stack.
- Consensys: Consensys builds Ethereum-layer infrastructure (Infura, MetaMask, Quorum) and enterprise tokenization tooling, providing alternative stack components for institutional DLT deployments that compete with Asseto.
- Hedera Hashgraph: Hedera operates the public hashgraph network and (via HashSphere) a private network for regulated markets. It is both a strategic investor and platform partner to ioBuilders, and a direct competitor for enterprise DLT workloads.
- R3: R3's Corda platform supports tokenization, digital identity, and capital markets workflows for banks and regulators — an established enterprise DLT incumbent overlapping with ioBuilders' institutional client base.
- Polygon Labs: Polygon provides Ethereum-scaling and tokenization infrastructure (Polygon CDK, Polygon PoS) used by financial institutions, an alternative on-chain layer that competes with Asseto's deployment options.
- Onyx by JPMorgan: JPMorgan's Onyx is a permissioned blockchain platform for tokenized deposits, payments, and securities, competing for the same institutional digital-asset workloads that Asseto targets.
Direct peers
- Tokeny: Tokeny provides an enterprise-grade tokenization platform (T-REX) for issuing, managing, and transferring compliant security tokens on Ethereum, mirroring Asseto's focus on regulated financial instruments.
- Securitize: Securitize is a tokenization platform for regulated securities and funds, offering issuance, transfer agent, and compliance services — directly comparable to ioBuilders' Asseto for tokenized financial instruments.
- Adhara (pre-merger): Adhara focuses on Ethereum and Hedera Hashgraph institutional blockchain solutions for banks — a directly comparable London-based peer that has now merged with ioBuilders to consolidate capability.
Emerging players
- Fnality International: Fnality is building DLT-based wholesale settlement systems with major global banks, including through the Adhara/ioBuilders ecosystem — directly comparable as a regulated digital-money and settlement-rail initiative.
