Why Choose Us
Direct Communication with Developers
Without going through a sales representative, the engineers who actually do the development directly listen to your needs and make proposals. This prevents miscommunication and achieves speedy and accurate development.
Agile and Flexible Response
Our agility is our strength, unlike large companies. We respond flexibly to "minor revisions" and "urgent requests." A dedicated contact person handles everything consistently, so you never need to re-explain the background.
Fair Pricing and Transparent Quotes
Because there are no subcontracting margins, we can propose fair prices. We provide detailed quotes with a breakdown of man-hours, making it easy to pass internal approval processes.
Security as Standard
NDA signing, OWASP-compliant development processes, and regular vulnerability assessments are included as standard. We also meet the security requirements of information systems departments.
