OysterQ

Fifteen million filed accounts. The forty that matter to your next pitch.

Market intelligence built from Norway’s company accounts: figures you can put in front of a board or an investor, a way to track the market your portfolio sits in, and a deep specialism in auditing and accounting that exists nowhere else.

What it does

Three specialised areas.

Each draws on its own sources. The market module reads filed company accounts; the auditor and accountant modules add the registers and assignment histories that describe who works for whom, and how that changes.

Market

Define the market you actually compete in, then examine it as closely as you would examine one company.

  • Build peer groups from the bottom up, and detect the anomalies that would distort them
  • Track market development in detail, year by year
  • Deep financial review of that market against any benchmark company

Auditors

The audit market as it moves: who holds which clients, where the work is going, and which companies are about to need an auditor.

  • Market share development and client counts
  • Auditor–client dynamics over time, and industry trends
  • Client prospect lists from forecasts and your own target areas

Accountants

The same portfolio view for accounting firms: who serves whom, how that has changed, and where a practice is growing.

  • Client relationships and their history
  • Movements between accounting firms
  • Prospects that match a practice’s existing book
How the market module works

Four steps, in order, because each one depends on the last.

The path through the market module is the path a careful analyst would take anyway. The product just refuses to let you skip a step.

01

Build the peer group

Start from a company or from criteria. Filter by industry, county, revenue, employees. Add or remove companies by hand. Companies that have since closed stay in the years they traded, so history is not quietly rewritten by today’s survivors.

02

Check it for anomalies

Before you read a single chart, OysterQ flags what would distort it: a company larger than the rest combined, a margin far outside the group, a year that breaks a company’s own pattern, a filing that looks like a unit error. Exclude them, see the effect, put them back.

03

Read the market

Revenue and earnings over a decade, cost structure, working capital, returns and capital. Every figure on a standard or group accounts basis, switched with one control. Compare the company against the rest of the market, or look at the market alone.

04

Keep the argument

Save the views that make your case into a project, in the order they should be read. When the underlying data is replaced, a saved view is marked as needing review rather than silently changing under its own title.

Built by people who know what a wrong number costs.

Market data is easy to produce and hard to trust. Most of the work in OysterQ is not in drawing charts — it is in making sure the figure on the chart is the figure you think it is.

  • 01One definition per number. The total on the peer list is the same total on the market chart, computed the same way.
  • 02Companies that stopped trading remain in the years they traded, so a ten-year market is the market as it was.
  • 03A share of a market that collectively lost money is reported as undefined, not as a negative percentage.
  • 04Saved analyses record which release of the data they were built on, and say so when that changes.
