Company builders + active engineers

We help build companies.

Turtle Moon works alongside early-stage teams on strategy, product, engineering and execution—while maintaining an active engineering practice across open standards, decentralized systems and developer tooling.

One practice. Two ways to build.

The work makes us better builders.

We stay close to the code. The problems we encounter while building companies inform the tools, infrastructure and standards we build next.

01 / WITH FOUNDERS

Build companies.

Work with builders who connect strategy, product and engineering. We help turn technical constraints into decisions, working software and a practical path to launch.

Build with Turtle Moon
02 / AT THE KEYBOARD

Build software.

Our own engineering work keeps that advice grounded. We build tools, contribute to open standards and share the artifacts behind our thinking so others can inspect the work.

Products & tooling

An idea is a starting point. Build the thing.

Software in development and the tools that got us here. Each has a status, a source and a clear place in our story.

01 / Desktop browserIn development

Bitcoin Browser

Development direction

A desktop browser for Bitcoin records, inscriptions and Runes. Explore supported content, follow related records and connect a user-run AI server for read-only research. The current development snapshot includes implemented features; public downloads and native platform qualification are still pending.

Turtle Moon HCS App

Built by Turtle Moon

A desktop interface for creating, submitting and reading HCS-20 point operations. The public toolkit connects a specification to an inspectable implementation. Its historical documentation labels the software alpha, and we have not confirmed a current supported release.

03 / Inscription discoveryHistorical

Hashinals.com

Built by Turtle Moon

HOL identifies Hashinals.com as a Turtlemoon-created platform for discovering Hashinal inscription numbers. It connects on-graph data with a way to find and view it. Current service availability and maintenance have not been confirmed, so this record links to the documented ecosystem work.

Turtle Moon Tools

Built by Turtle Moon

Open-source tooling for Hedera NFT workflows, created from a practical ecosystem need. Turtle Moon released its minting software so other builders could inspect and extend the work. The original beta remains part of our engineering history; current support is unconfirmed.

Build with Turtle Moon

Strategy that survives contact with the product.

Discuss your project

Product direction

Work through the problem, the user and the path to a useful product. We connect positioning and product decisions to an implementation your team can evaluate, with a clear scope and an explicit reason for what gets built next.

Hands-on engineering

Move between architecture, interfaces and infrastructure with people who work in the code. We bring the same habits to company building that we bring to tooling: inspect the constraints, build a working version, test it and keep learning from use.

Delivery you can inspect

Make progress visible through working software, clear milestones and practical QA. We help teams connect decisions to delivery, from an early prototype through launch, with enough structure to know what is ready and what still needs work.

Open standards

Solve it once. Make it useful to others.

Open standards contributions, with individual authorship and status. Turtle Moon participates in the HOL ecosystem alongside other builders.

Company-building case study

From infrastructure need
to independent company.

Turtle Moon announced HGRAPH.IO in June 2022 to make Hedera data easier for developers to access through GraphQL. Today, Hgraph operates its own blockchain data and infrastructure business.
