🟦 The Real Problem: You’re Investing, But Not Winning
Your team has access to more AI tools than ever before. So why do only 18.9% of legal professionals feel confident using them? Even more concerning: while 61.2% of legal departments provide broad access to AI tools across their teams, that confidence gap reveals the truth—this is an adoption crisis, not a technology crisis.
The most expensive technology is the one your team doesn’t use effectively.
This isn’t about finding the perfect vendor or building the perfect custom solution. It’s about making the right strategic choice now so you’re not scrambling to fix it later. In 2026, the stakes are higher, and the decision framework is clearer. Here’s how to navigate it.
🟦 Why 2026 Changes Everything: Four Market Forces Converging
The AI-First Operating System Has Arrived
AI is no longer optional—it’s the operating system for modern legal work. Research shows that 80% of legal professionals expect AI to have a high or transformational impact on their work within five years. Forward-thinking teams aren’t just experimenting anymore; they’re embedding AI into core workflows. The question has shifted from “Should we use AI?” to “How do we source and integrate it strategically?”
Vendor Consolidation Is Creating Real Risk – And It’s Accelerating
The legal tech market is consolidating at unprecedented scale, and it’s creating supply chain exposure that GCs can no longer ignore. Just look at 2025: the legal industry witnessed the largest M&A transaction in legal tech history when Clio acquired vLex for $1 billion (November 2025), expanding its reach into enterprise legal departments. Before that, Reveal’s $1 billion acquisition of Logikcull and IPRO signaled aggressive consolidation in e-discovery. Earlier in 2025, major players continued the trend: Wolters Kluwer acquired Brightflag, Consilio acquired TrueLaw, Elevate acquired Legadex, and Opus 2 acquired Uncover. Even this month, emerging AI-first vendors like Lawhive acquired UK law firms and Eudia acquired Out-House.
What this means for you: If your current vendor gets acquired (as many will), you face three new risks your procurement team may not be anticipating:
1. Data Migration Chaos: Acquiring companies often consolidate platforms, forcing customers off legacy systems. You’ll face costly and risky data migration, API incompatibilities, and loss of custom integrations you built over years.
2. Feature Discontinuation & Vendor Lock-In: Post-acquisition, vendors often retire certain products or “rationalize” feature sets to consolidate engineering resources. Your chosen platform may become unsupported or deliberately de-prioritized in favor of the acquirer’s offering—leaving you with costly replatforming decisions.
3. Pricing & Service Level Shock: Newly acquired companies often face price increases of 50-300% post-close. Your favorable contract terms become irrelevant when the acquiring company “renegotiates” post-integration. Exit data portability clauses you thought you had negotiated become conveniently buried in new master service agreements.
Choosing a vendor is now a bet on their viability and the viability of the acquiring company. Your procurement strategy needs to account for exit plans and data portability from day one.
Compliance Is No Longer Negotiable
With the EU AI Act fully effective as of August 2, 2025, and similar regulations on the horizon globally, data privacy and AI governance have become non-negotiable. You’re personally accountable for the security posture of every tool in your stack. The average large firm now manages 18 or more different generative AI tools—each with its own potential vulnerabilities, each a point of compliance risk.
Regulators are actively monitoring. The EU AI Office is now operational, with penalties up to €35 million or 7% of global turnover for non-compliance. This isn’t theoretical—it’s here, and it’s enforced.
ROI Accountability Is the New Standard
Budget pressure isn’t easing. Departments are expected to do more with less, shifting from”cost center” to “value driver” status. Every technology investment—whether built or bought—must have a clear, defensible path to ROI. The good news: 53% of organizations are already seeing ROI from AI, largely through efficiency gains, cost reduction, and faster turnaround times. The bad news: only 20% are actively measuring it.
🟦 The Five-Factor Framework: Make the Right Call
Use this disciplined approach to cut through vendor pitches and internal politics. This isn’t a gut-feel decision—it requires rigorous analysis.
1. Business Need Clarity: Is This a Differentiator or a Commodity?
Start here. Is the process you want to improve a core part of your competitive advantage, or is it a standard operational function?
A “differentiator” is a unique workflow that wins or retains clients. Think: proprietary risk analysis for a specific sector, unique contract negotiation insights, or a signature due diligence process.
A “commodity” is a back-office function that simply needs to be done efficiently. E-billing, standard NDAs, routine document management—these need to work well, but they don’t differentiate you in the market.
How to decide: Map the process. If it directly impacts client acquisition, retention, or your firm’s market positioning, scrutinize it as a potential differentiator and lean “build.” If it’s internal and non-client-facing, prioritize efficiency and lean “buy.”
2. Total Cost of Ownership (TCO): Look Beyond the Price Tag
TCO miscalculation is the #1 reason technology decisions fail. A “buy” decision isn’t just the annual license fee. A “build” isn’t just developer salaries.
The true cost includes:
- For “Build”: Developer salaries + benefits, infrastructure costs, security overhead, ongoing maintenance, compliance updates, and at least 20% of initial development cost annually for maintenance
- For “Buy”: License fees, implementation costs, data migration, system integration, user training, change management, and ongoing vendor management
Real math: If you build a contract management system to “avoid subscription fees,” but pull two senior lawyers off strategic work for 4 months plus pay a contract developer $150/hour, your 5-year TCO often doubles a leading SaaS solution. The opportunity cost alone is usually the killer.
How to decide: Model all costs over a 3-5 year horizon. Include hidden costs like IT administration, security compliance, and the cost of talent diverted from billable or strategic work. Get a CFO or operations leader to validate the numbers—gut feel fails here.
3. Speed to Value: When Time Is the Deciding Factor
How quickly must this problem be solved?
Building a custom, enterprise-grade solution takes 18-24 months. Buying and implementing a proven platform can deliver value in as little as 6 weeks. Compliance deadlines don’t care how elegant your custom build is.
Example: After a major acquisition, a General Counsel has 6 months to consolidate 125,000 contracts from multiple legacy systems and achieve full visibility for regulatory deadlines. Building from scratch is not an option. They buy a market-leading CLM platform and partner with a service provider to accelerate migration. Result: 100% visibility in time, compliance achieved, crisis averted.
How to decide: If the pain point is causing immediate financial loss, creating compliance risk, or putting you at competitive disadvantage, “buy” is almost always correct. If you’re executing a long-term strategic vision with runway, “build” becomes viable.
4. Integration & Scalability: Does It Play Well With Others?
No technology exists in a vacuum. Your new tool must integrate seamlessly with Microsoft 365, your DMS, your finance platform, and your core systems. Fragmentation = data silos = manual workarounds = dead adoption.
Integration failures are adoption killers. A powerful AI drafting tool that can’t connect to your DMS, forcing lawyers to download, modify, and re-upload documents constantly, doesn’t work in practice—no matter how advanced the AI.
Scalability matters too. Will your solution handle 10x growth in data volume without a complete rebuild?
How to decide:
- For “Buy”: Make robust API access and proven integrations non-negotiable. Ask for reference customers. Verify integration complexity with your IT team.
- For “Build”: Plan for APIs from day one. Base your architecture on modern, scalable infrastructure (cloud-native, not monolithic). Document everything.
5. Control & Customization: The “Good Enough” vs. “Perfect” Trade-off
When you “buy,” you cede control of the product roadmap, feature prioritization, and core architecture to a third party. When you “build,” you control your destiny. But beware the customization trap—modifying a bought tool to fit outdated processes only codifies bad habits.
The goal is configuration (flexibility within a standard framework), not deep customization (brittle, un-upgradable systems).
Example: A global financial services firm needs a contract analytics tool to track highly specific risk clauses across 50+ jurisdictions. No off-the-shelf tool meets this niche requirement. They decide to build on their existing data platform, maintaining control over analytical models and reporting. This is a strategic “build.”
How to decide: If an off-the-shelf solution meets 80-90% of your needs and is highly configurable, lean “buy.” If vendor limitations would create significant business obstacles, lean “build.” The sweet spot? A “buy” decision with light customization, not a customized system that’s hard to upgrade.
🟦 Real-World Snapshots: Build vs. Buy in Action
The Strategic Build: Internal AI Advisor at a Global Tech Company
A large tech company’s legal team was drowning in repetitive regulatory questions from the business. Instead of buying another point solution, they decided to build on their existing Microsoft 365 platform. They developed a custom AI-powered chatbot, trained on their internal legal knowledge base and compliance playbooks.
Result: A secure, self-service tool providing instant, consistent answers. Senior lawyers freed up for high-value strategic work. The build made sense because this was a differentiator—a proprietary tool reflecting the company’s unique regulatory landscape.
Lesson: “Build” works when you control unique data/knowledge and can justify the team investment.
The Emergency Buy: Contract Visibility at a Healthcare Company
After acquiring several smaller entities, a healthcare services company suddenly owned 125,000+ contracts scattered across inaccessible legacy systems. Zero visibility into risks. Renewal deadlines fast approaching. Compliance at risk.
Time was the critical factor—there was no time to build. They selected a market-leading CLM platform, engaged a service provider for rapid migration, and within months achieved 100% contractual visibility.
Lesson: When speed is critical and compliance is on the line, “buy” beats custom builds every time.
🟦 Quick Self-Assessment: Which Path Fits You?
Answer these five questions. Tally your “yes” answers.
- ✓ Is this a non-core, commodity function? (E.g., e-billing, standard NDA review, routine document management)
- ✓ Must you achieve ROI within 6 months? (Compliance deadlines, budget pressure, competitive threat)
- ✓ Does this process represent unique competitive advantage that you actively market to clients?
- ✓ Do you need 100% control over the feature roadmap and data security, with zero vendor dependencies?
- ✓ Do you have dedicated, long-term budget for an internal development team, including ongoing maintenance, security, and UX design?
Scoring:
- 0-2 “Yes” answers → Lean “Buy”
- 3+ “Yes” answers → Lean “Build”
🟦 What Happens Next? The 2026 Reality Check
The “build versus buy” decision is one of the most consequential choices you’ll make as a legal leader in 2026. It’s not a purely technical choice—it’s a strategic bet on your department’s future budget, your risk profile, and your ability to deliver measurable value to the business.
Getting it wrong costs you:
- Wasted technology spend
- Frustrated users and low adoption rates
- A fragmented tech stack that creates more problems than it solves
- Compliance exposure
Getting it right unlocks:
- New efficiency gains and measurable ROI
