About intotheopen

intotheopen is a proactive content intelligence platform redefining how strategic communication teams approach content strategy. We help teams predict, validate, and optimise high-impact content before publication and beyond, reducing wasted effort and maximising content performance.

Through AI-driven data insights, intotheopen ensures content success is never left to chance. With growing interest from leading comms agencies, enterprises, and investors, we're entering an exciting phase of growth. As we prepare to launch our POC/MVP, we're seeking a skilled and ambitious technical co-founder to help transform our vision into reality and shape the future of content intelligence.

What You’ll Be Building

You’ll work with intotheopen’s technical advisor, Paul King, a strategic AI architect and AI/ML expert who has already designed the initial POC/MVP tech stack.

Our MVP includes:

• Validation tools (semantic, tone, SEO, sentiment)
• AI-powered content optimisation
• Post-optimisation forecasting and version comparison
• Performance tracking

The platform architecture is modular and built for scale, powered by React (frontend), Python/Node (backend), GPT-based models (AI), and hosted on a containerised cloud setup.

Your Role

As intotheopen's Technical Co-Founder, you’ll:

• Lead the development of the MVP alongside our advisor
• Make key technical decisions for scaling the platform
• Own and iterate on product features based on market feedback
• Collaborate closely with the founder on product strategy and vision
• Have experience in building scalable SaaS products (ideally in MarTech or AI)
• Possess strong skills in React, Python or Node.js, ML pipelines, and cloud infrastructure (AWS/GCP)
• Be familiar with NLP, LLMs (GPT), and AI optimisation workflows
• Be comfortable working in an early-stage, fast-paced startup environment
• Bonus: experience with containerisation (Docker, Kubernetes), PostgreSQL, and content analytics tools

What You’ll Get

• Equity ownership in a high-potential MarTech startup
• The chance to shape a company from the ground up
• Participation in strategic decisions and long-term growth
• Collaboration with a commercially focused founder and a supportive transnational advisory board
