build

AI demos are easy. AI in production is hard. We start from the customer, building enterprise-grade AI that consistently delivers.

Here's some of what we've built and our thinking behind it.

Introducing Tristan Ratchford: Catalyst’s new CTO

Lloyd Hilton, Head of Hg Catalyst, sat down with him in his second week. They talked about why he joined Catalyst, how the engineering problems compare to what he was building at Datadog, and what kind of people he is looking for as the team grows.

Hackathon: 40 teams, three cities, 48 hours

More than 40 product and engineering teams from across the Hg portfolio are gathering in London, Paris, and New York to build agentic AI products, live and in parallel, over 48 hours.

How we think about evals in production

How we build evals into AI products, who owns quality, and five things we're watching as the space evolves.

Product

Behavioural modelling for banks and credit unions

ProductModelIQ 
CompanyEmpyrean
What it Does

Enables banks and credit unions to calibrate, test, and document how financial instruments like loans, deposits, and credit cards actually behave. ModelIQ replaces static, one-off consultant studies with ongoing, institution-specific calibration and governance.

Complexity

Datasets with 100 million daily transactions must be segmented, modelled, and calibrated per institution. Every model output needs a full audit trail and transparent documentation, so regulators and examiners can interrogate assumptions directly rather than treating the model as a black box.

Introducing Hg Catalyst

We've officially launched Catalyst. Operating from hubs in London and New York with a scaled capacity of over 80 AI engineers, product managers, and designers.

Product

AI-powered compliance and fair lending analysis

ProductNtelligence
CompanyNcontracts 
What it Does

Tools that transform compliance workflows. Complaint Ntelligence automatically categorises customer complaints, spots patterns, and recommends remediation. Regression Ntelligence automates fair lending analysis that previously took weeks and expensive consultants, delivering answers in minutes.

Complexity

The model must isolate legitimate credit factors like income and credit history from potential bias signals in lending decisions. When regulators scrutinise the output, every statistical conclusion must be defensible, making precision in the underlying regression modelling non-negotiable. 

Product

Agentic AI for wealth advisers and asset managers 

ProductNexus AI
CompanyFE fundinfo
What it Does

AI agents that work alongside wealth advisers to handle call preparation, follow-ups, portfolio monitoring, and operational tasks. Nexus AI improves adviser productivity and client outcomes while giving firms visibility on cost-to-serve across their adviser base. 

Complexity

There's no objective ground-truth for adviser-client interactions, and outcomes like investment returns play out over months, not minutes. Building eval frameworks where success is inherently subjective required a fundamentally different approach.

Product

Agentic AI for community association management 

ProductCephai+ 
CompanyCINC
What it Does

Native, embedded AI productivity layer across the CINC platform, enabling community managers to prioritise work, automate workflows, manage communications, and execute actions across HOAs. Provides portfolio-wide benchmarking, reporting, and performance analytics. 

Complexity

Property managers have to collaborate across an ecosystem of homeowners, boards, vendors, and regulators. Building AI that operates across these stakeholders, each with different needs, permissions, and context, requires agents that coordinate with each other without losing accuracy across associations.

Product

Agentic AI for treasury operations 

ProductGSmart AI
CompanyGTreasury 
What it Does

AI agents that automate routine cash forecasting and treasury risk management. GSmart AI agents take complex financial data and transform it into relevant, actionable insights for CFOs and treasury teams. Every output is traceable back to source data.

Complexity

Cash forecasting spans multiple entity structures, currencies, and industry-specific configurations, each with unique customer setups. Every AI-generated insight must be fully traceable to source data, requiring explainability at every step of the chain across these diverse environments.

Product

 AI agents for financial planning and analysis teams

ProductOne Intelligence
CompanyProphix
What it Does

I-driven intelligence layer within Prophix's FP&A platform that unifies structured and unstructured financial data to enhance forecasting, planning, and insight generation. Designed to deliver proactive, actionable insights for finance leaders rather than reactive reporting.

Complexity

FP&A classification and vocabulary differ for every customer, so a generic model fails immediately. The text-to-SQL agent auto-personalises based on each customer's historical data, learning their specific terminology and schema to return accurate results without manual configuration.
