WORK HISTORY
Customer Success & Account Manager (English Speaking Saas Customers) @Hysopt
GB
Customer Success & Account Manager at Hysopt, a physics-based digital twin platform for hydronic HVAC systems.I work with M&E consultants, contractors, energy companies and D&B across the UK to ensure they gain measurable value from Hysopt throughout the full customer lifecycle — from onboarding and adoption to growth and renewal.My role sits at the intersection of customer success, account management and technical awareness of HVAC engineering workflows. I act as the primary point of contact for customers, supporting them with day-to-day use of the platform, aligning Hysopt with their internal design and modelling processes, and coordinating deeper technical or project support with our engineering specialists where required.A key part of my focus is helping engineering teams embed Hysopt into real projects, ensuring strong adoption across teams, and demonstrating clear ROI through improved design confidence, reduced risk, and better performing systems. Alongside this, I manage commercial discussions including renewals, licence growth, training and service packages.I maintain close relationships with engineers, digital leads and decision-makers, running regular check-ins and QBRs, tracking usage and engagement, and developing account plans that support long-term partnership and ARR growth.I also act as a voice of the customer internally, feeding back insights on workflows, integrations and product needs to support Hysopt’s ongoing development, particularly around BIM, building simulation and wider software integrations.This role combines relationship building, commercial responsibility and an understanding of how engineering teams design, model and optimise HVAC systems in practice.

ABOUT JACK MALTBY
At Hysopt, I help building owners, consultants, and contractors accelerate decarbonisation by improving the performance of their heating and cooling systems. Our physics-based SaaS platform enables engineers to design, simulate, and optimise complex hydronic systems—cutting energy use, reducing emissions, and ensuring systems operate as intended throughout their lifecycle.As UK SaaS Manager, I partner with leading M&E consultants, building operators, and energy service providers to bring clarity and performance assurance to projects targeting Net Zero Energy Building (NZEB) standards. From feasibility to operation, I support clients in embedding digital-twin-based workflows that combine engineering precision with measurable sustainability outcomes.Previously at Veolia Water Technologies, I managed key accounts delivering large-scale water and energy solutions—an experience that strengthened my ability to navigate technical, commercial, and sustainability-driven challenges across multi-stakeholder environments.I’m passionate about using digital tools and physics-based simulation to help the built environment deliver on its Net Zero ambitions—through smarter design, validated performance, and long-term energy efficiency.Focus Areas:Hydronic system optimisation & digital twinsHVAC design validation & simulationNet Zero and decarbonisation strategySustainable design for large buildings & campusesLet’s connect if you’re exploring how hydronic optimisation and digital engineering can help your projects perform better, cost less, and move closer to Net Zero.
