Moat.
Speed.
Allocation.
The platform moat that survives 2028 is being chosen this year.
This briefing tells you which platform moats survive 2028 in accounting and CFO advisory as AI rewrites build economics. Read it before your R&D allocation locks for the decade.
The 10-page briefing. Worth 20 minutes.
One email. One PDF. Worth twenty minutes of your week.
We send it once. Work emails only.
Tuesday 08:30, practice operations meeting. Four things on the screen. The fourth compliance RFP lost to Aiwyn this quarter. A senior tax partner's retirement timing email arrived over the weekend. Your second-best advisory lead took the Deloitte AI-and-advisory package on Friday. The Managing Partner's €5M tuck-in proposal on the agenda.
You are not running one tech-spend envelope. You are running two, and only one is on your scorecard. One funds Karbon, CCH, Wolters Kluwer, Microsoft, and the AI-compliance layer to defend the shrinking book. The other funds what has to exist by 2028: the partner-IP extraction programme, the firm-owned client graph, the methodology encoded into infrastructure the firm actually owns.
The moat that matters in 2028 is not in the vendor stack. It is in the layer underneath it that only your firm can build.
Your advisory partners have sold this argument to owner-managed clients for a decade. The firm has not yet run it on itself. The briefing below is what you want in your hand before the next partnership council.
Build Velocity. Product Defensibility. R&D Capital Allocation.
Three questions every advisory-firm CTO is tracking. The third is the crux. The first two are how you earn the right to answer it.
Is our internal team shipping anything the firm owns, or only renewing what it rents?
Karbon renewal, CCH licence, Copilot rollout. All necessary. None is build. Build is a working agent that sits on twenty years of a client's files and prepares the next owner-manager conversation. A retirement-risk model that runs quarterly. A firm-owned methodology system.
What does our stack do that Aiwyn or Botkeeper at ten percent of our unit economics cannot copy?
Karbon and CCH are available to every competitor. The moat is what the firm encoded on top of the stack. Twenty years of client history. Partner reasoning. Methodology. A two-person AI-native cannot replicate this without your client base.
Is our tech-spend envelope one instrument or two?
Plateau capital runs Karbon, CCH, Microsoft, and the AI-compliance defence. Compounding capital builds the 2028 practice-intelligence moat. On one hurdle rate the first wins every quarter. On one scorecard the second does not exist.
What you get when you download
An 11-page report for CTOs, Heads of Technology, and Directors of Practice Technology at mid-market European accounting and CFO advisory firms. Designed to be read in one sitting before your next partnership council.
Your industry, your practice-technology function, and why they are one problem
What is happening to mid-market accounting and CFO advisory: Big 4 compressing advisory margins from above, PE-backed consolidators absorbing compliance from below, AI-natives repricing individual billable-hour streams. What is happening inside your function: vendor-AI consolidation, seventeen AI features on seventeen workflow tools, and a tech-spend envelope being pulled in five directions at once.
Four moves across build engine, platform and data, product thesis, and R&D bench
Consolidate the stack and ship what the firm actually owns. Build the practice-intelligence graph underneath the vendor layer through partner-IP extraction, firm-owned client graph, data-rights architecture. Stand one firm-owned practice-intelligence agent alongside the stack. Rebuild the internal team around the build, not the admin.
Five questions for your next partnership council
Is your tech-spend envelope one instrument or two? Name the AI-native in your category and how many RFPs the firm has lost. How many months to reconstruct client-specific intelligence if the senior partners retired? Every week your advisors sell this transformation to clients. Is your Q1 boundary agreement with the Managing Partner written?
Calibrated for each seat at the table.
