About

Rob Hallam is a full-stack developer, serial entrepreneur, and digital nomad who built a $12K/month SaaS business while traveling the world. As the founder of Liftoff MVP agency and creator of multiple successful products including PentestList.com, Indiedex.app, and SuperX.so, Rob exemplifies the modern indie hacker approach to building sustainable online businesses.

From Tech Layoff to $10K/Month SaaS

Rob's entrepreneurial journey began after being caught up in the 2023 tech layoffs. Despite holding a BSc in Computer Science with First Class Honours (87% weighted average, graduating top of his cohort), he decided to forge his own path as a solopreneur. His goal was ambitious yet clear: build a $10,000/month SaaS while documenting the entire process and living on savings.

The results speak for themselves - it took Rob just 10 months to reach his $10K/month revenue milestone, proving that with dedication and the right approach to MVP development, anyone can build a successful software business. Today, his flagship product SuperX.so generates $12K in monthly recurring revenue, while Liftoff has brought in over $38K helping other entrepreneurs validate their startup ideas.

Building PentestList: A Community for Cybersecurity Tools

One of Rob's most impactful contributions to the developer community is PentestList.com, a curated platform for discovering and reviewing penetration testing resources, ethical hacking tools, and cybersecurity content. The platform addresses a critical problem in the infosec space: fragmentation of tool discovery and lack of recognition for security tool developers.

What Makes PentestList Unique

PentestList functions as a community-driven treasure chest where security professionals can:

  • Discover curated cybersecurity tools with detailed comparisons and community reviews
  • Browse by category including port scanners, vulnerability scanners, SQL injection tools, and exploitation frameworks
  • Stay updated with the latest penetration testing tools added daily
  • Support developers by providing visibility and recognition for innovative security tools

The platform serves both novice penetration testers learning the ropes and seasoned security experts seeking cutting-edge tools. Rob even developed a Chrome extension for pentesting resources, making it even easier for security professionals to access the tools they need during assessments.

Open-Source Security: The Phishing Prevention Project

Beyond commercial products, Rob has made significant open-source contributions to cybersecurity. His phishing-project on GitHub provides organizations with cost-efficient tools to reduce phishing attack risks through intelligent simulation and targeted training.

Key Features of the Phishing Project

The tool enables security teams to:

  1. Simulate internal phishing emails sent to employees with realistic attack scenarios
  2. Monitor employee responses to identify vulnerabilities in organizational security awareness
  3. Calculate heuristic risk scores for each employee based on their behavior patterns
  4. Intelligently automate scheduling of phishing simulations based on risk data
  5. Generate comprehensive reports to guide security training investments
  6. Target training efficiently at high-risk employees rather than blanket approaches

This Python-based tool demonstrates Rob's commitment to making cybersecurity more accessible and actionable for organizations of all sizes, not just enterprises with massive security budgets.

The Indie Hacker Philosophy

Rob actively shares his journey and insights with over 32.1K followers on X (formerly Twitter), where he documents his experiences building multiple SaaS products simultaneously as a digital nomad. His content focuses on practical lessons learned from shipping products quickly, validating market demand, and balancing multiple revenue streams.

What You'll Learn From Rob

Follow Rob's X account to gain insights on:

  • MVP development strategies that help you launch in weeks, not months
  • SaaS pricing and positioning based on real customer feedback
  • Building in public and leveraging transparency for community growth
  • Developer productivity techniques for solo founders managing multiple projects
  • Remote work optimization while traveling internationally

Rob's approach aligns perfectly with the indie hacker movement, where developers like Pieter Levels and Marc Lou prove that small teams (or solo developers) can build profitable businesses without venture capital. His success with tools like Auth.js for authentication demonstrates the power of leveraging modern development tools to move faster.

Indiedex: Connecting Indie Hackers

Understanding the challenges of solo entrepreneurship, Rob created Indiedex.app to help indie hackers connect, collaborate, and grow together. The platform serves as a discovery tool where developers can:

  • Find potential co-founders with complementary skills
  • Discover indie makers building in similar niches
  • Network with entrepreneurs at various stages of their journey
  • Share resources and knowledge within a supportive community

This reflects Rob's belief that while building solo is possible, building with a community accelerates growth and prevents the isolation that often comes with solopreneurship.

Technical Stack and Expertise

Rob's projects showcase proficiency across the full development stack:

Programming Languages

  • Python for security tools and automation
  • JavaScript/TypeScript for web applications and browser extensions
  • HTML/CSS for responsive web design

Development Focus Areas

  • Full-stack web development
  • Browser extension development
  • Cybersecurity tooling and automation
  • SaaS architecture and scaling
  • API integrations and automation

His quantCasino project (a quantum randomness-based casino) and covidcatch game (created for Oxford Digithon 2020 using pygame) demonstrate versatility beyond typical web development, showing comfort with game development and experimental technologies.
