Contract Development

We undertake custom software development projects and contract work in the metaverse, XR, online games, and related fields.

What We Offer

Build your own in-house real-time communication engine, delivered as source code.

Real-time communication engines are often offered as binary libraries or managed cloud services. We take a different approach: we design and build a custom engine for your business domain and deliver it as source code, so you can operate, extend, and secure it in-house.

Our Strengths

Areas of Expertise

  • (1) Metaverse, XR
  • (2) VTuber virtual live broadcasting
  • (3) Online games
  • (4) Other systems requiring real-time communication
  • (5) Software research and development

Our Approach

  • We developed our own low-level libraries and can rapidly deliver solutions based on extensive real-time communication development experience.
  • We specialize in building high-performance systems (up to 2000+ concurrent connections per core), while avoiding unnecessary trial and error.
  • From application features to real-time communication engines, we provide clients with complete source code.
  • In addition, we perform advanced customization and low-level optimization according to client requirements and system characteristics to maximize performance.
  • For projects that require high‑performance real-time communication engines, please feel free to contact us for a free consultation.

Most Recent Work

  • We recently built a domain-specific real-time engine for a VTuber live broadcasting system serving a well-known voice actress idol group in Japan.

What We Build

  • (1) Custom real-time communication engines tailored to your business domain
  • (2) Server-side infrastructure and client SDKs (Unity, etc.)
  • (3) Business logic and application features
  • (4) Research & development and technical feasibility studies

Service Plans and Pricing

2025 December revision

(1) Custom Development Plan

  • Pricing: Individually estimated based on project complexity, scope, and duration
  • Reference rate: Approximately USD $130 per person-hour
  • Warranty: If defects attributable to us are found within 6 months after delivery, we will correct them free of charge.
  • For long-term projects, we may propose phased development and delivery under separate milestone-based contracts.

(2) Technical Feasibility Plan (PoC)

  • Use case: When you wish to verify technical feasibility before committing to full-scale development, we perform minimal implementation for technical validation over a period of three months.
  • Pricing: USD $45,000
  • If the expected effort for technical validation exceeds three person-months, please contact us for a separate estimate.
  • The outputs from technical validation are not intended for use in production services. Because of simplified design/architecture and temporary implementations, some or all deliverables may not be reusable in the main development phase.

(3) Joint Development Plan

  • We are a specialized technology company focusing on fundamental technologies such as real-time communication. While we are highly specialized, for large-scale product development that requires broader capabilities, we work together with partner companies (in Japan and China) to deliver end-to-end solutions. After consultation with our partners, we determine the project structure that best serves the client.
  • Service model: We are responsible for core components such as real-time communication, while collaborating with partner companies on the rest of the project.
  • Terms: Determined individually based on project size and scope.

(4) Contractor Services

  • Use case: Projects that require a very high degree of flexibility.
  • Hourly rate: USD $130
  • Workload: 1–4 days per week (flexible scheduling available)
  • Work location: Remote from Japan or on-site in the Greater Tokyo Area
  • Timezone: JST (UTC+09:00). We can adjust our working hours to accommodate meetings regardless of timezone differences.
  • Warranty: When we act as the technical decision-maker on the project for deliverables created directly by us, if defects attributable to us are found within 6 months after delivery, we will correct them free of charge.
  • Discount: 5% off the hourly rate if the 6-month warranty on deliverables is waived.

(5) Warranty Extension Option

  • Use case: When you wish to extend the warranty period for deliverables in custom development projects.
  • This option extends the free correction period for defects attributable to us beyond the standard 6-month warranty period after delivery.
  • Pricing: 1% of the total deliverable amount per month of extension

We retain the following rights and do not transfer them to clients:

  • (1) Copyrights, patent rights, know-how, trade secrets, and other intellectual property rights that we already own prior to the contract start date
  • (2) General algorithms, data structures, programming techniques, design patterns, and other technically reusable components
  • (3) Technologies already in the public domain, industry-standard technologies, and implementation methods that must be adopted due to technical necessity

For items not covered above, we grant clients a non-exclusive license to use our proprietary software to the extent necessary for the agreed business purposes.
