Find consultancies

Find consulting firms by practice, size, and client sector

Consultancies do not fit firmographic boxes. The one thing you want to filter on, the practice they actually run, lives in prose on their website and nowhere else.

No database has a field called practice area. A boutique advising banks on regulatory change and a firm doing digital transformation for retailers look identical in a firmographic record: same code, same headcount band, same city. The difference is written on their site in sentences.

So the qualifier is a research column, not a filter. Exa grounds an AI column against live pages, which reads the practice pages and case studies and writes back a short structured answer with its sources. Open Web Ninja and People Data Labs supply the firm; Blitz API then LeadMagic supply the contact.

The result is a row you can argue with. Every research cell keeps the pages it read, so when a partner asks why their firm was filed under operations rather than strategy, the answer is one click away.

Example searches

Ask for it the way you'd say it

Every search below runs on the same hosted Tables, with the cost previewed before anything is spent.

  • Practice read off the site

    consultancies whose site describes a finance transformation or cfo advisory practice

    The answer is written to the row with the pages it came from, so a wrong call is correctable without re-sourcing the list.

  • Sector their clients sit in

    advisory firms whose case studies are mostly healthcare and life sciences clients

    Client sector is inferred from published work rather than the firm's own industry code, which is far too broad to filter on.

  • Partner-led boutiques

    independent consulting firms between ten and eighty people with named partners on the site

    Partner listings become rows of their own, so the person who owns the buying decision is on the list instead of a generic contact.

Plays

Three motions you can run this week

Each one is a chain of Oxygen primitives — the same hosted objects your workspace already has, composed.

  • Practice read from the website

    Every firm carries a structured practice label with the pages that produced it.

    1. Tables
    2. Records
    1. 1Source firms by region and size, then dedupe on domain before anything metered runs.
    2. 2Add a grounded research column, then promote firms matching your definition to Records.

  • Partner-level outreach

    The message reaches a named partner in the relevant practice, not a general enquiries address.

    1. Tables
    2. Sequences
    3. Messages
    1. 1Expand the firm's people page into contact rows and filter to the practice you care about.
    2. 2Run the email waterfall, enroll what verified, and read every reply in one inbox.

  • Rank before you spend

    The expensive columns only ever run on firms that already passed a free check.

    1. Tables
    2. Workflows
    1. 1Score rows on free columns first: size, region, published work, and site depth.
    2. 2Gate the enrichment step behind that score so low-fit firms never draw credits.

Who you can reach

Roles you can find at consulting and advisory firms

Reachability is per channel: a role marked for mobile is one the phone waterfall usually resolves, not a guarantee for every record.

Filters you can search on

  • Practice areas described on the site
  • Client sectors named in case studies
  • Partner and headcount bands
  • Independent or network member
  • Country, region, or city
  • Publishes research or a report series
  • Offers implementation as well as advice

Firms that publish case studies and name their partners resolve very well, because the research column has something to read. Advisory boutiques with a one-page site and no published work are the weak slice: the firm resolves, the practice cell comes back thin, and a human read is needed before anything is sent. Partner names are easier to find than partner emails at the smallest firms.

Data sources

What the data actually comes from

Every value lands with its provider and cost recorded on the cell.

  • Op

    Open Web Ninja

    Firm listings with address, phone, and site, which anchors a city or country sweep.

  • People Data Labs

    Headcount, founding year, and the people at a firm, including partner-level titles.

  • Exa

    Grounds the research column against live practice pages and case studies, sources kept on the cell.

  • Blitz API

    Leads the work-email chain, which keeps most rows away from the metered lanes entirely.

  • LeadMagic

    Second lane for email and mobile on unresolved rows, billed only when it returns a result.

Run these on Oxygen's managed credits, or connect your own provider keys and pay the vendor directly — the same columns, the same runs, the same provenance either way. See every integration.

Limits

Where this stops

  • A research column reads what is published. A firm doing most of its work under NDA looks smaller and narrower than it is, so treat a thin practice cell as missing evidence rather than a disqualification.

FAQ

Questions people ask first

Why can't I just filter consulting firms by industry code?
The code says consulting and stops. It cannot separate a regulatory advisory boutique from an operations implementation shop, and those two buy very different software.
How accurate is a website-derived practice label?
Good enough to rank on, not good enough to send blind. Every answer keeps the pages it read, so a reviewer checks a sample in minutes and adjusts the prompt before the list goes out.
Can I find individual partners rather than the firm?
Yes. The people page expands into contact rows linked to the firm and the email chain runs per person. Filter to the practice you sell into so a privacy partner is not pitched procurement software.
How do I avoid paying to enrich firms I will reject?
Order the columns so the free checks run first. Size, region, and site depth cost nothing, and the waterfall only runs on rows that survived. That ordering is usually the biggest saving on a build like this.
Do networks and member firms count as one company?
Treat them as separate rows unless you sell centrally. Member firms usually buy their own tools, so dedupe on domain, keep the network name as a column, and decide per campaign which level you address.
Can I reuse this list for a partnership motion later?
Yes. The table stays in the workspace with its history, so months later you re-run the contact column, compare what changed, and enroll the same firms in a different sequence.
