Vaka Consulting

Overview

Vaka Consulting is a technology consultancy that helps governments, enterprises and mission-led ventures plan and build digital systems where people need to trust the data. Clients bring an early idea or a problem, and the firm shapes the technology plan, tests it with a focused prototype or proof of concept, and coordinates the people who build it¹. Its specialty is records that several parties rely on, such as investment flows or proof of real-world results, using tools like blockchains and verifiable credentials (digital certificates anyone can check are genuine)¹.

The team brings an Asia-Pacific and Africa perspective to its delivery work, combining enterprise architecture (planning how an organization's technology fits together), product design and digital finance experience¹. On Cardano, Vaka Consulting is an enterprise member of Intersect², a member-based organization for the Cardano ecosystem³. Founder and CEO Phil Lewis has served on Intersect's Steering Committee and set up its Enterprise and Government Adoption Working Group¹. Intersect's 2026 meeting notes name him as the group's lead⁴.

Key Features

• Help from first idea to launch. Vaka Consulting works in five steps: understand the problem, design the target system, prove it with a prototype, coordinate product, design, engineering and specialist partners, and prepare it to grow¹.
• Records people can check. The firm uses blockchains, verifiable credentials and privacy-aware designs so data keeps a clear trail of where it came from, with controls on who may change it¹.
• Housing-finance marketplace experience. For Empowa, a marketplace that finances affordable housing, Vaka says it provided product, architecture and technology leadership from the start, helping establish blockchain-based investment and transaction workflows¹.
• A marketplace other projects can reuse. Vaka Consulting publishes open-source smart contracts (programs that run on the blockchain) for a marketplace where a community trades NFTs using its own token instead of ADA^5,6. The security firm Anastasia Labs audited these contracts⁷.
• Code packages for Cardano apps. The firm's public vaka-js library offers TypeScript packages that help developers build applications that interact with Cardano⁸.

What to Expect

The Vaka Consulting website is a single company page, not an app. Visitors find the four service areas, the five-step approach, selected client work, short bios of the team, and links to email, LinkedIn and X for starting a conversation¹.

Organizations considering a project can see how the firm works in practice. Beyond Empowa, where the listed outcome is climate-smart homes financed in Mozambique, Vaka acts as technology and platform partner for ClimaFI¹. There it helps connect operational, financial, environmental and social data to improve financing, impact checks and reporting¹. The firm also works on reusable designs for government services, such as letting citizens control who can see their data¹.

Developers can browse the firm's public code repositories on GitHub, which hold the marketplace contracts, the matching marketplace app, and a prototype interactive map of the Cardano ecosystem^9,10. The marketplace code came out of a completed Project Catalyst proposal led by Phil Lewis⁶. Project Catalyst is Cardano's community-voted funding program, and this grant paid for testing, an audit and documentation for a marketplace Empowa had already built in collaboration with Harmonic Labs⁶, the team that created plu-ts, a tool for writing smart contracts in TypeScript¹¹. The final milestone moved that code into two Vaka Consulting repositories, with instructions for configuring and deploying your own copy¹².
