How high-growth firms are winning today: Strategies that set them apart

Advisory-first models, embedded AI, and integrated tech stacks are separating leaders from the rest

The 2025 picture: Growth, but not by accident

U.S. firms are reporting strong performance again this year, according to the 2025 U.S. Future Ready Accountant report: 86% report revenue growth and 84% report profitability gains. But the firms pulling ahead aren’t just doing more work; they’re working differently.

High-growth firms combine advisory-first engagement, AI built into everyday workflows, and integrated cloud systems that keep data moving across the firm. These choices make it easier to deliver consistent service and create space for higher-value work, turning client touchpoints into an opportunity to advise, not just deliver.

What does “working differently” look like in practice? Here’s how high-growth firms are setting themselves apart, and what those choices mean for firms aiming to follow their lead.

1. Advisory becomes the backbone of the business

For high-growth firms, proactive, data-driven, and repeatable advisory isn’t just a supplement; it’s their core approach. These firms are more likely to use predictive models (29% vs. 24% overall) to forecast client needs and automated alerts (27% vs. 24%) to initiate timely outreach and address issues before they arise. As advisory's share of firm revenue grows to 13% (from 10% in 2024), it's clear why firms continue developing structured programs.

Strategic takeaway: Treat advisory as part of the core business model, not a side service. Invest in tools that support data-driven personalization, so staff can use client data to guide conversations and build processes that make proactive outreach routine, not reactive.

2. AI shifts from pilot projects to daily workflows

The 2025 Future Ready Accountant report found that AI weekly usage among high‑growth tax and accounting firms is mainstream, especially for high-growth firms; 76% use AI at least weekly, and they are more likely to use AI daily than their peers (34% vs. 31% of all firms). Looking forward, 87% plan to increase their investment in AI-enabled tech, and 45% anticipate increasing their investment by 10% or more.

Responsible AI now powers research acceleration, document summarization, and predictive insights, making early‑warning insights routine and improving accuracy across engagements.

Strategic takeaway: Don’t stop at basic automation or standalone AI tools. Take the next step and embed AI into your daily workflows. Use it to save time and improve accuracy, so your team can focus on client-facing work.

3. Integration turns disconnected tools into a single growth engine

Owning more software isn’t enough; connecting it is what drives scale. Report data shows that high-growth firms are more likely to be fully cloud‑based and more likely to run highly integrated stacks. In the U.S., 86% of high‑growth firms operate in the cloud (vs. 81% overall).

Why does integration matter, and why are more integrated firms also more likely to outperform their peers? A more integrated tech stack feeds cleaner data to people and AI, enabling automation and better decision-making.

Strategic takeaway: Make integration a priority. Connect core systems – tax, CAS, advisory, and portals – to reduce friction, improve data quality, and unlock automation at scale.

4. Talent enablement replaces talent churn

The theme running through the 2025 U.S. Future Ready Accountant report: enablement beats churn. High‑growth firms embed workforce development alongside tech rollouts, so new tools stick and staff spend less time on data entry and rework, more time on client conversations.

Across the U.S., firms are prioritizing developing their staff’s advanced technical skills (31%, up from 27% in 2024) and investing in training, a pattern high‑growth firms amplify with change management and role‑based upskilling.

Strategic takeaway: Link every tech investment with a talent strategy. Build confidence through training and automation, so staff can focus on advisory and client engagement instead of repetitive tasks.

The high‑growth flywheel: How these pieces work together

When advisory is structured, AI handles routine work, and systems seamlessly share data, every client interaction becomes more effective and valuable. When every meeting, report, and email helps move the client forward, momentum compounds, with better decisions leading to stronger relationships and recurring advisory work.

Winning firms build this flywheel deliberately, not by chance.

The bottom line

High-growth firms are pulling ahead because they operate like modern, data-driven businesses: advisory-first, AI-assisted, and deeply integrated. The data backs it up, and the playbook is clear:

• Make advisory central to the entire business model
• Embed AI into workflows
• Connect the firm's tech stack
• Enable team members to thrive
