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
