What Kristaps Grinbergs. 2025. does

Kristaps Grinbergs is an individual blockchain, mobile, and fullstack developer operating as a solo, remote-first consultant based in Latvia, offering CTO-as-a-Service and product development engagements across full-stack web, native iOS, and Ethereum-based Web3 projects. Revenue is generated through direct client consulting (project or hourly), with demand sourced via a personal website portfolio, technical blog, and active presence on LinkedIn, Twitter, GitHub, and Telegram channels. His core technology stack spans ReactJS and Material UI on the web, SwiftUI/RxSwift for iOS and Apple TV, and Solidity for Ethereum smart contracts (including ERC-20, ERC-721, ERC-4337 account abstraction, and EIP-712 meta-transactions), with Firebase, Stripe, iCloud, and Google Sheets used for backends and payments.

Beyond consulting, Kristaps maintains a personal portfolio of consumer and B2B products. These include the Latvian consumer apps Weather Latvia, Dodies.lv (outdoor activities), Augi & Draugi (plant-based dining), Hashberg (iCloud-synced hashtag manager), and Vibur (events/emotions calendar), plus Sharentic (sustainable living, SwiftUI + Firebase + Stripe), Vaal Dashboard (ReactJS-based securitization/revenue-based financing dashboard), and Salto X (a token incentive plan platform for remote companies). He previously co-founded Qminder, a global-scale queue management company whose customers included Bolt, Uber, Lyft, and The Olympic Games; the native iPad sign-in and Apple TV apps for Qminder also remain in his portfolio.

The business is a sole proprietorship rather than a registered corporate entity: there is no parent company, no institutional investors, no funding rounds, no subsidiaries, no patents, and no disclosed revenue. Pricing is quote-based via direct outreach ([email protected]), with no publicly disclosed pricing tiers or formal sales channels. Strategic positioning rests on cross-domain expertise and the Qminder track record, marketed primarily through content (Solidoity and SwiftUI tutorials on kristaps.me/blog), conference speaking (DappCon Berlin, June 2025), and developer-community presence on GitHub and Twitter.

Others

• Qminder: Queue management SaaS Kristaps previously co-founded. Not a direct competitor but the entity through which he built his marquee-client track record (Bolt, Uber, Lyft, Olympics) — relevant context for evaluating his background.

Emerging players

• Runtime Verification: Formal verification and smart contract auditing firm for blockchain projects. Niche overlap in high-end Solidity/security consulting work similar to Kristaps' smart contract services.
• Argent Labs: Smart contract wallet (ERC-4337 account abstraction) team. Comparable as a Web3 product team working in the exact account-abstraction niche Kristaps specializes in.

Direct peers

• Braintrust: Decentralized talent network connecting freelance engineers (including Web3 specialists) to clients. Comparable as a freelance-platform competitor for high-end developer engagements.
• Andela: Global marketplace for vetted remote software engineers. Comparable as an enterprise channel for senior freelance developers, overlapping in target buyer (startups needing senior tech talent).
• ChainSafe Systems: Web3 engineering firm specializing in Ethereum, Solidity, and protocol-level development. Direct comparable as a boutique smart-contract and dApp development service provider with similar Solidity/blockchain focus.
• OpenZeppelin: Smart contract development and security audits for Ethereum-based projects. Highly comparable given Kristaps' Solidity expertise and use of OpenZeppelin libraries referenced in his blog.
• Toptal: Marketplace for elite freelance software engineers including mobile and blockchain developers. Direct comparable business model — selling senior freelance developer talent to clients at premium rates.

Broad incumbents

• Alchemy: Major Web3 developer platform providing RPC, APIs, and developer tooling on Ethereum and other chains. Adjacent incumbent that owns much of the developer mindshare Kristaps competes for via his Solidity content.
• Consensys: Largest Web3 software company offering blockchain developer tooling, smart contract development, and consulting across Ethereum ecosystem. A broad incumbent that absorbs much of the same enterprise Web3 dev demand Kristaps targets.
