Shared infrastructure for financial markets

Banks never replace their technology. They build on top of it.

Forty years of settlement systems, risk engines and half-finished projects sit under every trading floor. We work out which layer is costing you money, and what it takes to cut through it.

What we do

We build the thing an industry needs but no single firm will pay for.

Some problems cannot be solved by one company buying software. Reconciliation, provenance, credentials, settlement — these need a shared standard or a shared utility, and someone has to design it and persuade the industry to adopt it.

That is our work. We have done it for tokenised gold, physical aluminium, securities finance data standards, seafarer credentials and real-world assets. The method is the same each time.

01 Find the gap
Identify where value exists but the standard, the trust layer or the access is missing.
02 Model it
Map the data and the business process end to end, not just the part you can see.
03 Design the utility
Usually shared or neutrally owned. A single-vendor product rarely solves an industry problem.
04 Build the case
Requirements, business case, adoption model, go-to-market. The whole package, not a slide.
05 Sell it in
To trade associations, consortia and the firms that have to agree before anything moves.
01

Post-trade & data standards

Reconciliation exists because two firms describe the same trade differently.

Every break you investigate, every affirmation you chase, every regulatory field you map twice comes back to one thing. There is no shared, machine-readable description of what happened. The industry built a whole operational discipline around not having one.

The Common Domain Model fixes that — but only for firms that treat it as a commercial programme, not a data project. It needs a consortium, a sequence, and a business case that survives a CFO.

We know this one from the inside. We proposed extending the derivatives CDM into securities lending and repo, and took it to ISLA and ICMA. Both adopted it. The CDM is now open-source at FINOS and underpins regulatory reporting.

  • CDM adoption strategy and business case
  • Consortium design and mobilisation, from problem definition to funded delivery
  • Regulatory reporting rationalisation across overlapping regimes
  • Vendor selection, commercial structuring and negotiation
  • T+1 readiness ahead of October 2027

What this costs you today

  • ◆Break investigation. Operations staff whose whole job is fixing mismatched descriptions.
  • ◆Duplicate reporting builds. The same trade mapped again for every regime, each with its own budget.
  • ◆Failed settlement. Buy-in exposure, funding cost and counterparty friction.
  • ◆Remediation. The cost of finding a reporting defect after the regulator does.
02

Tokenisation & digital assets

The technology question closed years ago. Distribution is still open.

Tokenised funds trade at scale. Collateral mobility is a board topic. Settlement in tokenised cash is being planned, not debated.

What has not kept up is commercial capability. Most firms here have good product and a sales approach that cannot navigate a bank, where the buyer is not one person but a group across trading, treasury, risk, operations, legal and technology — each with a separate reason to say no.

We have sat on both sides. At a regulated issuer we ran growth for a tokenised gold token, designed institutional use cases for collateral and structured products, and led AUD stablecoin work with two Australian majors.

  • Institutional go-to-market for tokenisation and digital asset infrastructure
  • Product and proposition design — tokenised commodities, funds, collateral, structured products
  • Adoption models for banks, treasuries, payment firms, exchanges and clearing houses
  • UK market entry against the FCA authorisation timetable
  • Partnership design across custody, issuance and distribution
FCA gateway opened 30 Sept 2026 · saving provision closes 28 Feb 2027

What this costs you today

  • ◆Stranded pilots. Years of proof-of-concept budget with no production path and no revenue.
  • ◆Trapped collateral. Assets you cannot pledge when you need to, because settlement is too slow.
  • ◆Intraday buffers. Cash held against timing, not against risk.
  • ◆Missed authorisation. Losing a market you already built for.
03

Risk computation · with technology partners

A risk number that arrives at 6am describes a market that has already moved.

XVA, margin and capital analytics across a full portfolio are among the heaviest calculations in finance. On conventional grids they need large compute estates, run overnight, and answer too late to change a trade. Meanwhile the quant team spends its time on plumbing instead of models.

We work with technology partners on commercial strategy and market positioning for leading-edge pricing and risk solutions — frameworks that vectorise calculations for parallel hardware such as GPUs, and that have been used for entity-level XVA and margining, model risk, reverse stress testing and wrong-way risk. The technology is theirs. Our job is taking it to market, and helping institutions judge whether the case stacks up.

  • Commercial strategy and positioning for risk and pricing analytics
  • Buyer mapping across quant, risk, treasury and technology
  • Business case — compute, energy, capital efficiency, quant productivity
  • Partner and ISV channel development

What this costs you today

  • ◆Grid compute and energy. Farms sized for one overnight batch you cannot question.
  • ◆Quant maintenance. Expensive people keeping a model estate alive rather than improving it.
  • ◆Capital held against imprecision. Buffers carried because the maths is coarse, not because the risk is real.
  • ◆Decision latency. Analytics that cannot answer inside the trading day.
04

Real-world assets

Assets with real value and no way to reach the people who want them.

The same problem repeats across illiquid asset classes. The asset produces genuine value. There is real appetite for exposure to it. Between the two sits no instrument, no price discovery and no route to the investor.

We design the product, the commercial model and the path to market. Work to date covers four asset classes.

  • Natural capital. A tokenisation and commercialisation model for conservation and ESG assets, developed with wilderness landowners in the United States. Set out in our paper Put a Penguin in Your Pension.
  • Commercial property. Tokenisation of asset manager property holdings, and distribution strategy for fractional exposure.
  • Collectibles. Fractional ownership of classic cars, including a review of the wallet, Layer 1 and Layer 2 landscape to pick the right adoption model.
  • Commodities. Tokenisation of in-ground assets, and how a token carries through the refining process.
Paper available on request

What this unlocks

  • ◆Illiquidity discount. Value lost only because the asset is hard to transfer.
  • ◆Minimum ticket. Demand that never arrives because the entry size is wrong.
  • ◆Administration drag. Manual transfer, registry and reporting cost across the asset's life.
  • ◆No price discovery. No secondary reference, so no confident primary allocation.
05

Market entry & commercial leadership

Most capital markets technology does not fail on product. It fails on access.

A new relationship at a tier-one bank is a two-year problem for most vendors. The buying group spans functions that do not report to each other, procurement runs to its own calendar, and the incumbent has an eighteen-month head start on every objection.

We work as a part-time commercial function: set the market entry thesis, build the buyer map, shape the pitch, and open the first conversations in person. Engagements are scoped, time-boxed and priced on deliverables.

  • Market entry thesis and segment priority for UK and European institutions
  • Fractional commercial leadership — proposition, pitch, pipeline design
  • First meetings opened personally at institutional accounts
  • RFP and RFI response, commercial structuring, negotiation
  • Sales coaching in PISTDC and MANACT

What this costs you today

  • ◆Burn per unlanded client. A year of commercial cost on a cycle that stalls before procurement.
  • ◆Wrong territory. A team selling hard into the segment least able to buy.
  • ◆Founder time. Your most expensive person taking first meetings.
  • ◆Ramp risk. Senior hires who take four quarters to reach a number the plan assumed in two.

Cost reckoner

Your numbers, not ours.

We publish no industry benchmarks, because the only figure that matters is the one inside your own business. Put your assumptions in and see what they add up to. Nothing is stored or sent.

How we engage

Scoped work, a named deliverable, and an end date.

01 · Frame

Two weeks. What is actually being bought or sold, who decides, and what the case has to prove. This often changes the question.

02 · Thesis

A written market entry or adoption thesis: segments in order, the buyer map, the objections, the sequence. This is the deliverable.

03 · Open

We make the first approaches ourselves. Warm routes where they exist, a clear point of view where they do not.

04 · Hand over

Engagements end. We pass over the map, the materials and the relationships, and write down what we got wrong.

Track record

Where the experience comes from.

A data standard extended into two new asset classes

The Field Effect / Delta Capita

Proposed extending the derivatives Common Domain Model into securities lending and repo. Built the case and took it to ISLA and ICMA. Both adopted it. The CDM is now open-source at FINOS and underpins regulatory reporting across derivatives, fixed income and securities lending.

Twelve tier-one banks in twelve months

The Field Effect / Delta Capita

Twelve new investment bank relationships opened, progressed and closed personally, structured as entry engagements into longer advisory and managed-service work.

A provenance registry for physical aluminium

GFT · Project Jupiter

An alternative to the LME warehouse system, built with the largest global aluminium producer by capacity. Full ex-works lifecycle modelled through logistics and storage, an Ethereum smart contract for provenance, a map-based interface, and a shared-ownership utility structure. Not taken to market after a change of sponsor; still used as proof of capability.

Tokenised gold, and a neutral issuer proposal

Paxos Trust Company

Doubled token value for a tokenised gold product. Designed institutional use cases across collateral, ETF alternatives and specie legal tender. Ran AUD stablecoin work with two Australian majors, proposing a single coin issued by a neutral third party against member bank balance sheets.

Ethereum code that ended up in Corda

GFT · RBS

Won and delivered an engagement re-engineering Ethereum code for scalability in a SEPA aggregator. RBS later donated the codebase to R3 and Corda.

Credentials for stranded seafarers

Bridgefort Maritime

During the pandemic, crews were stuck at sea because no industry-wide record of vaccination or certification existed. Built the data model, an Ethereum proof-of-concept wallet, and a co-owned shared service for shipowners. Strong support from crewing functions; never funded.

Who you work with

Julian Eyre

Waterstone is a small practice. Engagements are led personally, which puts a deliberate limit on how much we take on at once.

Julian has spent twenty years selling complex technology into capital markets — trading and risk platforms, post-trade, reconciliation, regulatory reporting and CDM — and a decade designing shared infrastructure for asset classes that lacked it. The combination is the point: understanding the product, and being able to navigate a bank that buys slowly and by committee.

Based in Kent, thirty to forty-five minutes from the City. Works in English and French.
