Enable your workforce to develop new skills faster and more effectively, enhancing productivity and engagement.
We rapidly develop a prototype AI agent to validate its effectiveness for a specific task. The PoC demonstrates real-world feasibility while minimising cost and delivery risk. A typical deliverable is a basic AI agent addressing one core use case.
Timeline: ~2 weeks
Once validated, the AI agent is developed into a fully functional solution and then deployed as a beta version, gathering data and feedback for further improvements. Key features are expanded functionality for broader use cases, performance monitoring and reporting tools and integration with your existing platforms.
Timeline: ~6 weeks
After the beta phase, we then perform the full release, including addressing the impact on team members with training and documentation. At this point the agent is ready to scale to meet your operational demands. This phase includes advanced optimisations, features, and the capacity to handle higher volumes and complexity.
Timeline: dependant on you
At Fifty One Degrees, we design AI solutions with people at the core. By combining cutting-edge automation with human oversight, our AI agents deliver precision, adaptability, and reliability. We focus on understanding your business goals and operational dynamics to create solutions that empower your team, improve efficiency, and elevate customer experiences, ensuring AI works for your unique needs.
Take three simple steps to start deploying AI in your business.
① Book an exploratory meeting
② Agree a proposal
③ Design & build your AI implementation
Standard chatbots are passive; they wait for input and provide static information. Fifty One Degrees’ AI Agents are active agents of change. They are “doers,” not just talkers. Our agents are integrated into your operational tech stack to perform complex tasks autonomously, such as underwriting loans, qualifying sales leads, managing supply chains, or handling full customer onboarding journeys. We design them to execute multi-step workflows that traditionally require human intervention, moving your business from simple automation to intelligent orchestration.
We reject multi-year digital transformation projects that never end. We operate on a “Ship, Learn, Iterate” methodology.
Proof of Concept (PoC): We deploy a working prototype to validate the use case in ~2 weeks.
Beta Release: A fully functional solution gathering real-world data takes approximately 6 weeks.
Scale: Full deployment timeline depends on your volume, but we prioritise rapid time-to-value. This ensures you aren’t paying for “consultancy slide decks,” but for working software that solves business problems immediately.
No. We believe in a “Human-in-the-loop” philosophy. Our goal is to remove the “robot work” from the human—the repetitive data entry, the initial triage, the mundane scheduling—so your team can focus on high-value, creative, and strategic work. We act as “Smart Enablers,” building tools that supercharge your existing team’s productivity and happiness. As seen in our work with Heatable and Equals Group, AI amplifies human ingenuity; it does not replace it.
Yes. We are technology agnostic and do not force proprietary “black boxes” on our clients. We work with the Modern Data Stack (Snowflake, dbt) and are implementation partners for leading AI technologies like Bland AI, ElevenLabs, and Relevance AI. Whether you use Salesforce, HubSpot, or a custom legacy ERP, our engineers build the pipelines (ETL/ELT) to ensure the AI Agent sits seamlessly within your current infrastructure.
While our methodology applies broadly, our deep domain expertise lies in sectors where high-volume data meets operational complexity:
Financial Services & Insurance: Automating underwriting, fraud detection, and FCA/PRA compliant risk modelling.
Home Improvement & Construction: Supply chain optimisation and lead scoring.
Retail & Travel: Dynamic pricing and personalised customer attribution.
Energy: Customer service automation.
Our founders, Nick Harding (FinTech scale-up veteran) and Mark Somers (Data Science PhD), have built these systems from the inside out, specifically for businesses scaling from £5m to £250m turnover.
Because we are practitioners, not just preachers. Large consultancies sell hours; we sell outcomes. We use these very same AI agents to run our own internal operations before we ever recommend them to you. We are a vertically integrated partner—meaning we don’t just advise on strategy; our forward-deployed engineers build, ship, and maintain the code. We focus on tangible ROI, not billable hours.
