## About Heliux Inc.

## Company Overview
- **One-liner**: Heliux provides an AI-powered all-in-one enterprise operating system that unifies cross-functional manufacturing operations—replacing legacy PLM, ERP, and MES systems.
- **Entity Type**: Private (Seed/Pre-Seed stage)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2023
- **Founders**: Alex Craig (CEO, former head of supply chain at Relativity Space) and Victor Jakubiuk (CTO, former co-founder and CTO of OnSpectra)

## Core Business
- **Primary industry**: Software Development for industrial manufacturing (industrials, aerospace, defense, robotics, clean energy)
- **Target customers**: B2B, mid-market to enterprise manufacturers; early-stage companies scaling from prototype to production
- **Mission**: To drive unprecedented velocity in manufacturing by modeling and powering the entire manufacturing enterprise as a single, coherent system.

## Products & Services
- **Heliux Platform**: An AI-powered, all-in-one enterprise operating system that natively connects engineering, supply chain, production, planning, accounting, and finance. It serves as a single system of record and execution, integrating product data, lifecycle management (PLM), supply chain operations, manufacturing execution (MES), issue management, and financial management.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (privately held)
- **Key Metric**: Total funding of **$4.7M** (USD 4,665,000) across two rounds (Pre-Seed Feb 2024: $2.3M; additional round Mar 2025: $2.4M). [linkedin.com](https://www.linkedin.com/company/heliux)
- **Notable Investors**: New Stack Ventures, Marlinspike, Humba Ventures, Amplify.LA, Crosscut Ventures, Lux Capital, Countdown Capital [cbinsights.com](https://www.cbinsights.com/company/heliux)
- **Growth Signals**: Emerging from stealth in Feb 2024 with first paying customers; building second version of platform; hiring for key engineering and leadership roles (Software Engineer, Chief of Staff).

## Competitive Advantages
- **All-in-one approach**: Replaces fragmented legacy systems (PLM, ERP, MES) with a single unified platform, reducing integration complexity.
- **AI-native**: Uses AI to automate menial tasks (e.g., supplier onboarding prepopulation) and can generate custom ERP systems in days instead of months.
- **Direct distribution**: Handles deployment and support directly, avoiding third-party resellers and enabling implementation in weeks (vs. 6–12 months for legacy systems).
- **Early adopter focus**: Targets early-stage industrial companies that have outgrown spreadsheets but cannot afford long, expensive implementations.

## Strategic Focus
- **Product development**: Building out the second version of the platform to deepen functionality across engineering, supply chain, and finance.
- **Customer acquisition**: Accelerating onboarding of customers in space, defense, robotics, and clean energy.
- **Team expansion**: Growing the engineering and leadership team to support product velocity and customer success.

## Why Work Here
- **Early-stage impact**: Join a venture-backed startup at its earliest stage (4–9 employees) where you can shape the product, culture, and technical direction from day one.
- **Founding team**: Work directly with experienced founders (ex-Relativity Space, ex-AI startup CTO) who are deeply technical and hands-on.
- **In-office collaboration**: The team works full-time from the San Francisco office (1700 Montgomery St, Floor 4), fostering close-knit communication and rapid iteration.
- **Backed by top-tier VCs**: Strong investor support from Lux Capital, Crosscut Ventures, and others provides resources and network.
- **Open roles**: Currently hiring Software Engineers and a Chief of Staff (see careers page at [jobs.ashbyhq.com/heliux](https://jobs.ashbyhq.com/heliux)).
