Procurement within the construction industry is traditional, analogue and ripe for disruption. We’re on a mission to help construction companies reduce costs and save time through our new AI procurement tool, Prolo. Our service leverages cutting-edge AI, including Large Language Models (LLMs), Natural Language Processing (NLP), and voice transcription, to bypass outdated practices in the construction industry. This technology enhances decision-making, increases efficiency, and delivers a superior user experience.

Vrumi connects people seeking affordable workspace to householders with daytime rooms to let. Our online community is free to join and use. Londoners get cheaper, nicer and more flexible places to work (no more expensive office rents or soulless co-working hubs). Householders make money from their properties (plus someone to keep the dog company and take in the Amazon deliveries). The company was founded by pioneering hedge fund manager Roddy Campbell (IFM Asset Management, Cross Asset Management) and entrepreneur-philanthropist William Sieghart (Forward Worldwide, Streetsmart, National Poetry Day). A compelling new innovation in the ‘sharing economy’, Vrumi is set to join global success stories like Airbnb, Zipcar and TaskRabbit.

Checkfirst exists to solve one of the biggest challenges in the Testing, Inspection, Certification, and Compliance (TICC) sector: operational inefficiency driven by outdated planning, scheduling, and verification processes. Every day, global TIC organisations depend on auditors, inspectors, and assessors to deliver critical work. Yet much of this work is slowed down by manual planning, fragmented workflows, inconsistent data, and systems that cannot manage the complexity of real field operations. Checkfirst builds AI products that remove these barriers. Our platform is designed around one core mission: To bring clarity, accuracy, and speed to every stage of the audit and inspection lifecycle. ScheduleAI Our flagship product, ScheduleAI, gives TICC planners a modern optimisation engine for scheduling auditors and inspectors. Traditional planning tools cannot compute skills, certifications, customer windows, durations, SLAs, travel constraints, workload distribution, and compliance rules at scale. ScheduleAI processes all these dimensions instantly and produces optimal schedules that improve utilisation, reduce travel, cut rescheduling, and accelerate certificate turnaround. Leaders in TICC choose ScheduleAI because it does not automate the old process. It replaces it with an intelligent operating model that reveals hidden capacity and transforms delivery performance. VerifyAI VerifyAI supports document assessors with accurate level 1 review. It accelerates early stage verification by checking consistency, completeness, and compliance indicators across documentation sets. VerifyAI does not replace decision making. It gives assessors a faster, more reliable start and removes repetitive manual checks. Why Checkfirst Our products integrate seamlessly into existing TICC workflows. They connect with sector specific tools, support multi country operations, and handle the complexity of different standards and audit types.
