The pressure

Market data spend keeps climbing, and the board keeps asking why.

Across the industry market data costs continue to grow relentlessly, and firms are consuming data from a wider range of vendors than ever before. Most firms still can't see what they own, use, or duplicate.

Where it hurts today

Inventory is fragmented across multiple systems and business units

Limited visibility into what data is owned, used, or duplicated

Time-consuming vendor searches slow discovery and onboarding

Users can't self-serve, so business workflows stall waiting on data

What you get

Visibility, control and discovery, in one catalogue.

Explore turns a sprawling vendor landscape into a single source of truth, then embeds it into the workflows where money is actually committed to data.

Visibility & governance

A standardised taxonomy and enriched metadata create one consistent view of usage and spend.

  • Clear visibility into product usage and cost allocation across business units
  • Consistent, structured spend reporting that reconciles to finance
  • Easy identification and removal of duplicate or overlapping products

Cost optimisation

Embedded into procurement, Explore drives smarter demand and strips out waste.

  • Guided selection so users request the right data from the outset
  • Reduced duplication through visibility of existing subscriptions
  • Lower cost via demand management and stronger vendor negotiations

Self-service discovery

A centralised, searchable catalogue that people actually want to use.

  • Faster discovery of relevant, available datasets
  • Filter to licensed products to avoid unnecessary purchases
  • Broader visibility of alternatives for competitive sourcing and RFPs
AI Assistant

Your AI market data assistant

Explore's assistant sits on top of the catalogue and your live inventory, so answers come back instantly, licence-aware, and ready to act on.

  • Query the catalogue, Expand's benchmarks, and your inventory using natural language.
  • Linked to your inventory, so it highlights already-licensed products and helps you avoid over-buying.
  • Significantly reduces time spent searching for products, answering user queries, and prepping for negotiations.
Try asking
"I'm having a challenging negotiation with Vendor X for Product Y. What alternatives are out there?"
"My securitised products team is looking for CMBS pricing data. What are we already licensed for?"
"What products am I buying from S&P, and how does my spend stack up against Benchmark?"
Expand Taxonomy Mapping

One messy line item in. A governed record out.

Expand's proprietary taxonomy is what makes the catalogue defensible, and we do the work for you. As part of the service, Expand maps every line of your inventory to our catalogue, enriching and standardising it, then delivers that mapping back to you via API feed for easy integration into your inventory systems and other internal tools. The result: reporting that finally reconciles, and duplication you can actually see.

Accurate by default

Automated inventory maintenance keeps every line item current and correct, with no manual upkeep.

Consistent, comparable reporting

Standardised product types mean spend finally reconciles and trends reliably year on year.

Reliable spend forecasting

Consistent, granular data makes forward spend predictable instead of guesswork.

Decision-ready for the business

Detail that's clear enough for business heads, giving leadership real visibility into what they pay for.

Where it pays back

Cost savings across the data life cycle.

Explore creates leverage at every point where a firm commits money to market data.

01 · New data request

Buy less, knowingly

Surface similar products you already license, and alternative vendors you haven't yet approached on price, before a new subscription is ever signed.

02 · Annual self-certification

Cut what you don't use

Show end users the product descriptions and metadata behind each line: do you still need this? Self-certification becomes transparent and effective.

03 · Contract renewals

Negotiate from evidence

Walk into renewals armed with the competing products and pricing context that move a negotiation, to secure a lower price or right-size usage.
