Janus Henderson Bets on Claude to Rebuild Its Investment Workflow

Janus Henderson, the global active asset manager that oversees nearly half a trillion dollars in assets, said on June 11, 2026 that it is putting Anthropic’s Claude at the center of two of its core workflows in a partnership built with General Catalyst’s transformation company, Percepta. The two systems are named PRISM, a global client intelligence and engagement platform for distribution teams, and LIBROS, an AI-native research management tool for investment analysts. Percepta will embed its own AI engineers, researchers, and product managers inside Janus Henderson to build the systems on top of Claude, with the same Mosaic orchestration platform the firm has used at other large enterprises.

The collaboration also extends a wider rollout of Anthropic’s Claude across Janus Henderson’s engineering, investment, distribution, and corporate functions, including the Claude Code developer tool and Cowork for general employees. The deal is the most concrete step yet in a multi-year effort by the firm to make its investment and distribution arms more responsive to client needs, and the first time those efforts have been built around a single frontier model and a single embedded engineering partner.

Janus Henderson Hands Two Workflows to Claude

The June 11 announcement frames the deal as more than a software purchase. Janus Henderson manages approximately half a trillion dollars in assets as of March 31, 2026, with offices in 26 cities, and serves an estimated 75 million individuals as of December 31, 2025, according to a footnote in the press release. PRISM and LIBROS are being built in collaboration with Janus Henderson’s technology teams and Percepta, and Anthropic’s Claude serves as the model layer for both. The full press release sits on Janus Henderson’s corporate site.

The release places the work in a 92-year-old firm’s strategy. Janus Henderson’s view is that AI is most impactful when it enhances human expertise, and the new tools are designed to put more of an analyst’s and a salesperson’s time into judgment and client work, not into data plumbing. Percepta’s role is to handle the engineering that connects Claude to Janus Henderson’s proprietary research, client, and market data, a job the firm says generic AI products cannot do well. The collaboration builds on Janus Henderson’s existing partnerships with Trian and General Catalyst, the venture firm that owns Percepta.

PRISM and LIBROS, Side by Side

PRISM is the client-facing side of the build. It runs on Claude and is designed to give sales and marketing teams a single, consistent tool across regions, helping them prioritize outreach, draw on internal and third-party data to understand what clients hold and what they need, and prepare personalized client communications.

LIBROS is the investment side. It also runs on Claude, but its job is to synthesize the firm’s internal research with external research and public market data, helping analysts and portfolio managers surface relevant signals faster. Both tools share the same model and the same embedded engineering team, but they sit on opposite sides of the firm.

The two products are designed to integrate only through the data foundation Percepta is constructing. PRISM leans on the client and market data Janus Henderson already collects, while LIBROS leans on the research libraries the firm’s analysts have built over decades. Janus Henderson has not committed to a public launch date for either tool, and the press release describes the work as ongoing.

Percepta Embeds Its Engineers Inside the Building

Percepta’s business model is built on embedding, not licensing. The firm sends its own AI engineers, researchers, and product managers into a client’s investment, distribution, and technology staff, where they work side by side with the client team. The aim, Percepta has said, is to construct the data and knowledge foundation that connects Claude to the client’s proprietary research, client, and market data, a job the firm says cannot be bought off the shelf. At Janus Henderson, the embedded team will work on the Percepta Mosaic platform, which the firm describes as an orchestration layer for AI transformation across research, product, engineering, workforce, and strategy.

The partnership is part of a small set of public Percepta engagements. When Percepta was unveiled in late 2025, General Catalyst said the firm had been quietly at work with global Fortune 500 customers, state governments, and parts of the US healthcare ecosystem, with founder Hirsh Jain, a former Palantir enterprise leader, at the helm. General Catalyst’s unveiling of Percepta lays out the playbook. Janus Henderson is the first publicly named financial services client of Percepta’s scale, and the deal gives Percepta a high-profile test of its thesis that AI-native operations beat bolt-on pilots. Hirsh Jain, Chief Executive Officer of Percepta, said the work is focused on strengthening research and market intelligence and elevating client engagement.

Why Off-the-Shelf AI Has Stalled on the Buy Side

Janus Henderson’s diagnosis of slow AI adoption in asset management is unusually direct. The press release argues that generic tools rarely fit how an active manager researches markets, manages portfolios, and serves clients, and that the value comes from connecting frontier AI to a firm’s own data and rebuilding core workflows around it.

That requires engineering inside the business. It generally takes engineering built into the business, the firm argues, not software bought off a shelf, a point that aligns with Percepta’s broader market claim that enterprises are still trying to bolt AI onto legacy infrastructure and processes. That approach, Percepta says, leaves enterprises in the paralysis of prototypes, neither unlocking short-term gains nor future-proofing them for the ever-growing potential of AI.

Asset management is a knowledge-intensive industry where reliable AI can help teams work faster and serve clients better. Janus Henderson is putting Claude directly into the hands of the teams managing investments and client relationships: from purpose-built tools like PRISM and LIBROS to Claude Code and Cowork across the firm.

Peter Nolan, Head of Asset and Wealth Management at Anthropic, gave that statement as part of the announcement, and the partnership is built on a model Anthropic has been pushing into regulated industries for months. The scale of the firm is part of the story. Janus Henderson reported AUM of $241.6 billion in equities, $158.3 billion in fixed income, $55.6 billion in multi-asset, and $24.1 billion in alternatives as of March 31, 2026, the most recent public breakdown on the firm’s website. The capability-level numbers sit on Janus Henderson’s “Who we are” page. Even small productivity gains on that base translate into material numbers for the firm’s competitors, which is why the wider industry is watching the rollout closely.

Anthropic Provides the Model, Percepta the Engineers

Anthropic supplies the model layer. Claude is Anthropic’s frontier large language model, and the firm is incorporated as a Public Benefit Corporation that develops and sells AI products for enterprise and consumer use. Percepta supplies the engineering layer. Founded inside General Catalyst and unveiled in late 2025, Percepta was set up to help large enterprises in healthcare, financial services, manufacturing, and government rebuild core operations around AI. The founding team includes people from Palantir, MIT, Meta FAIR, Google, and Citadel, and the firm has named strategic partnerships with Anthropic and AWS.

The two companies have been moving in tandem. Percepta named Anthropic as a strategic partner at launch, and Kate Jensen, Anthropic’s Head of Americas, said Percepta’s differentiated approach to building solutions with customers will help businesses across several industries incorporate Claude into critical workflows. At Janus Henderson, that same pairing of model and embedded engineers is now being applied to a near-half-trillion-dollar balance sheet, with the stated aim of making the firm the most technologically sophisticated asset manager in the world. The deal makes the Janus Henderson engagement not a one-off deployment of Claude, but a long-running rebuild of how the firm works.

What is Percepta?

Percepta is a transformation company fully owned by venture firm General Catalyst, unveiled in late 2025. Its model is to embed its own AI engineers, researchers, and product managers inside a client’s organization, working on its Mosaic orchestration platform to rebuild core operations around AI. Janus Henderson is the first publicly named financial services client of Percepta at this scale.

What is Anthropic’s role in the partnership?

Anthropic supplies the AI model layer, Claude, that powers both PRISM and LIBROS. Anthropic is incorporated as a Public Benefit Corporation, and the firm develops the underlying model, while Percepta and Janus Henderson’s technology teams handle the engineering that connects Claude to the firm’s proprietary data.

How big is Janus Henderson?

Janus Henderson reported approximately half a trillion dollars in assets under management as of March 31, 2026, with offices in 26 cities worldwide. The 75 million client figure cited in the press release is an estimate of individuals as of December 31, 2025 whose assets or future benefits are invested in Janus Henderson investment products.

Why is this partnership notable for the asset management industry?

Janus Henderson is one of the largest traditional active managers in the world, and the partnership is built around embedding AI at the workflow level rather than bolting on a generic chatbot. Janus Henderson’s own diagnosis is that off-the-shelf AI products have not fit how active managers research markets, manage portfolios, and serve clients, and that the value comes from rebuilding core workflows around frontier AI connected to the firm’s own data. The rollout is a public test of that thesis at scale.
