Celaton — IDP Software Vendor

UK-based intelligent document automation vendor offering the inSTREAM platform, acquired by LSE-listed AdvancedAdvT Ltd in July 2024.

Overview

Celaton is a Milton Keynes-based intelligent document processing (IDP) vendor whose inSTREAM platform automates high-volume document workflows using machine learning. The company was acquired by AdvancedAdvT Limited (LSE AIM: ADVT) on 1 July 2024 for £5.0 million cash, net of £1.5 million cash acquired. The deal required approval under the UK National Security and Investment Act before completion.

At acquisition, Celaton reported £3.3 million in revenue for the 12 months ended 30 June 2023, with 80% of that revenue recurring through subscriptions and transactional fees. EBITDA before development costs was £1.2 million for the same period. Celaton became the fifth software company acquired by AdvancedAdvT, which also holds businesses in healthcare compliance, human capital management, and business solutions. All 22 Celaton employees were retained post-acquisition.

Vin Murria, AdvancedAdvT's Executive Chairperson, held approximately 45% of Celaton prior to the deal. BGF Investment Management, a substantial AdvancedAdvT shareholder, held a further 45%. Karen Chandler, an AdvancedAdvT director, serves as Celaton COO and is a minority shareholder. The transaction was therefore classified as a related-party deal under AIM rules.

HFS Research placed Celaton as an Aspirant in its 2022 IDP Market Scan, and Everest Group gave the same classification in its IDP Products PEAK Matrix 2023. Both assessments reflect Celaton's specialized focus and smaller scale relative to enterprise-tier competitors like ABBYY.

How inSTREAM works

inSTREAM is built around a self-learning model that improves with every document it processes. Unlike template-based robotic process automation (RPA) tools that require reprogramming when document formats change, inSTREAM adapts without manual reconfiguration. Gina Gray, Celaton's Commercial Director, describes exceptions as handled "in-flight as part of the standard process" rather than routed to a separate queue, which keeps straight-through processing (STP) rates high even for variable document types.

The platform ingests documents from paper, email, fax, EDI, and social media through a single unified workflow. It classifies each document, extracts structured data, validates against business rules, enriches records against external systems, and routes exceptions to human reviewers only when confidence thresholds are not met. The ML algorithms continue learning from each human correction, progressively reducing the volume of exceptions over time.

Prior to the AdvancedAdvT acquisition, Celaton invested £2.3 million in product development over two years, targeting AI capability improvements, a redesigned web user interface, and expanded multi-language support. The platform now covers 128 languages. Infrastructure moved from London data centers to AWS cloud in 2024, improving scalability and disaster recovery for SaaS customers.

Use cases

Invoice automation

Celaton reports an 86% reduction in invoice handling time for accounts payable workflows. The system extracts invoice number, date, amount, and line items, validates each against purchase orders, and routes discrepancies for review based on configurable tolerance rules. Named enterprise customers TalkTalk and Currys use inSTREAM for high-volume e-invoicing, according to the AdvancedAdvT acquisition announcement.

Sales order management

The platform delivers 75% efficiency gains in sales order processing by handling EDI, email, PDF, and image inputs through one workflow without intermediate transformation steps. Order details and fulfillment information are captured automatically and pushed to ERP systems via REST API or web services.

Claims automation

Celaton reports a 74% reduction in claims transaction costs through automated intake and document handling. The system extracts claim amount and policy reference, verifies against policy terms, and routes complex cases to adjusters based on configurable risk thresholds.

Correspondence management

For high-volume inbound correspondence, Celaton reports an 85% reduction in manual handling time. Documents are sorted by type, matched to customer records, and responses can be generated and dispatched automatically based on classification and content.

Retail and hospitality

Tortilla Mexican Grill, the UK's largest fast-casual Mexican restaurant chain, selected inSTREAM to support a 10-location expansion, demonstrating the platform's applicability beyond financial services into retail operations.

Capgemini partnership

Capgemini has been Celaton's primary systems integrator partner for over four years, growing to 12 live customer deployments with a further four in the pipeline at the time of the AdvancedAdvT acquisition. The partnership validates inSTREAM's fit for enterprise-scale deployments where a major SI manages implementation and ongoing support.

This transaction is a great opportunity for our customers and our team alike. We will have access to more investment as well as a larger pool of digital transformation expertise across the wider group.

Technical specifications

Company information

Celaton operates from Milton Keynes, UK, with 22 employees. The business sits within AdvancedAdvT's portfolio alongside four other software companies acquired in July 2023. The 80% recurring revenue base and £1.2 million EBITDA before development costs indicate a stable subscription business. Post-acquisition access to AdvancedAdvT's investment capacity and cross-portfolio customer base represents the primary growth lever for inSTREAM's development roadmap.

Jim Chase, Executive Chairman of Celaton, framed the acquisition as access to "a larger pool of digital transformation expertise across the wider group." Vin Murria described inSTREAM as "immediately beneficial to the wider AdvT client base, with its e-invoicing, AI, document processing IP centric product."
