## About Eridan

## Company Overview
- **One-liner**: Eridan is a U.S.-based technology company that has developed a fundamentally new radio architecture using direct polar modulation and Gallium Nitride to deliver high-performance, low-power, and low-cost 5G connectivity for private networks, rural broadband, industrial sites, and national infrastructure.
- **Entity Type**: Private (rapidly growing startup; pre-IPO equity offered)
- **Headquarters**: Sunnyvale, California, United States
- **Founded**: Not publicly available (leadership team with decades of experience suggests a recent startup; exact year not listed)
- **Founders**: Douglas Kirkpatrick (Co-Founder & CTO), Dubravko Babić (Co-Founder & President, Eridan Croatia); key executives include Omid Tahernia (President & CEO) and Atiq Raza (Executive Chairman)

## Core Business
- **Primary industry**: Wireless telecommunications / 5G infrastructure / Open RAN hardware
- **Target customers**: Enterprises deploying private 5G, mobile network operators, industrial/utility sites, rural broadband providers, and national defense organizations (B2B primarily)
- **Mission or purpose**: "To connect the planet to empower a sustainable, shared future" by making 5G connectivity affordable and energy-efficient everywhere.

## Products & Services
- **[Digital Radio Unit with Ultra-Clean Signal™]**: A fully digital, polar modulation-based radio built using Gallium Nitride (GaN) that delivers up to 5× lower power consumption and significantly reduced size and cost versus legacy systems. Supports Open RAN architectures and achieves high spectral efficiency for AI-driven and high-demand applications. Deployed for Private 5G, rural broadband, and industrial use cases.

- **[Field-Tested Performance]**: In public demonstrations, Eridan sustained over 100 Mbps at 1.7 km using only 0.3 watts, proving viability for long-range, low-power connectivity.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company)
- **Key Metric**: Company claims its novel transmitter architecture decreases the cost and power required to roll out 5G by **10 times**; total funding rounds not publicly listed.
- **Notable Investors/Partners**: Backed by a leadership team with backgrounds at DARPA, Qualcomm, AMD, Motorola, Xilinx, and Ikanos; specific institutional investors not named in available materials.
- **Growth Signals**: Active hiring (multiple engineering roles in Sunnyvale and Zagreb, Croatia), growing team with presence in two countries, field validation results, and inclusion in Open RAN ecosystem discussions.

## Competitive Advantages
- **Ultra-Clean Signal™**: Proprietary polar modulation technology that eliminates the power/performance trade-off of traditional radios, allowing longer range and higher capacity at much lower power.
- **GaN-based design**: Enables higher efficiency and smaller form factor than legacy silicon-based radios.
- **Cost and power reduction**: Up to 10× lower roll-out cost and 5× lower power consumption compared to traditional 5G equipment.
- **Proven leadership**: Team combines deep expertise in RF, semiconductor, defense communications, and large-scale hardware/software execution.

## Strategic Focus
- Expand Private 5G adoption in industrial (smart factories, AI-driven automation), rural broadband, and national infrastructure segments.
- Continue optimizing the radio for Open RAN integration and compliance.
- Scale production and drive down unit costs to make pervasive connectivity economically viable.
- Leverage field test results to build credibility with operators and enterprise buyers.

## Why Work Here
- **Culture**: "Casual and energetic environment" with collaboration and communication driving outsized results. The Sunnyvale office features big windows (even in the lab), is walking distance to downtown and Caltrain, and fits the entire team for company parties.
- **Remote/Hybrid Policy**: Not explicitly stated, but on-site roles are listed (Sunnyvale and Zagreb); likely office-centric with some flexibility.
- **Notable Perks & Benefits**: Pre-IPO equity, generous PTO, 401(k) with automatic matching, and health/dental/vision insurance. Emphasis on empowering employees and building a productive work environment.
- **Engineering Culture**: Hands-on work with cutting-edge RF, GaN, and digital signal processing; small, growing team offering significant impact and visibility. The company is solving hard physics and engineering challenges in wireless.
