Frequently Asked Questions

Tech404 is a technology company based in Yerevan, Armenia. We build hardware, software, IoT devices, and digital products. Unlike agencies that outsource, everything we deliver is built in-house by our permanent team of engineers and designers.

We are based in Yerevan, Armenia. Our entire team works from our Yerevan office, with GMT+4 timezone that overlaps well with European business hours.

We’ve built products for construction tech (BuildGuard), smart infrastructure (ValveTech), consumer electronics (SoundFlow), education technology (TabHero), and retail tech (ScriptScreen). We’re open to any industry where hardware meets software.

Tech404 was founded in 2022. In that time we’ve shipped 30+ products, completed 10+ IoT hardware projects, and built solutions for clients across multiple countries.

Yes. This is our core differentiator. We handle everything from PCB design and firmware to full-stack web applications and mobile apps. Having both capabilities under one roof means faster iteration, better integration, and single-point accountability.

Absolutely. We offer end-to-end development: product strategy and scoping, architecture design, hardware prototyping, software development, testing, and deployment. We can also help with manufacturing preparation and investor pitch decks.

No. Every line of code, every circuit board, and every design is created by our in-house team. We don’t use freelancers or subcontractors. You work directly with the people who build your product.

For software: Next.js, React, TypeScript, Node.js, PostgreSQL, Prisma. For hardware: KiCad, Altium, C/C++ for firmware, various microcontrollers (ESP32, STM32, Arduino). For design: Figma, Blender, After Effects.

Web application development starts from $2,000 for simple apps and goes up to $15,000+ for complex SaaS platforms. Admin dashboards start from $1,500, APIs from $1,000, and landing pages from $800. We provide detailed estimates after an initial discovery call.

PCB design starts from $1,500, IoT device development from $3,000, and hardware-software integration from $2,500. Prototyping starts from $2,000. Final costs depend on complexity, component selection, and production volume.

Landing pages: 1-3 weeks. Web applications: 4-12 weeks. SaaS platforms: 8-20 weeks. Hardware prototypes: 2-8 weeks. IoT devices: 6-16 weeks. We provide specific timelines during the scoping phase.

Both. For well-defined projects with clear scope, we offer fixed-price contracts. For ongoing development or exploratory projects, we work on a time-and-materials basis with weekly reporting.

Contact us through the form on our website, email info@tech404.am, or call +374 41 818 088. We’ll schedule a free 30-minute discovery call to understand your needs, then provide a detailed proposal within 3-5 business days.

A brief description of your idea or problem is enough. If you have wireframes, technical requirements, or reference products, share them — but it’s not required. We’ll help you structure everything during the discovery phase.

Yes. We’re happy to sign a non-disclosure agreement before discussing your project details. We treat all client information as confidential regardless.

Yes. Upon project completion and final payment, you receive full ownership of all source code, hardware designs (schematics, Gerber files, BOM), documentation, and deployment credentials. No lock-in, no licensing.
