STOP Customizing
STOP Technical Debt
START Leveraging AI

"You're paying $500K/year to build custom software inside someone else's prison — and calling it a 'platform investment.'"

The Hidden Reality: You're Already Building Custom

Here's the dirty secret of enterprise platforms: you're building custom software anyway. You just don't call it that because it happens inside someone else's system.

When you buy Salesforce, HubSpot, or ServiceNow, you're buying a starting point — not a solution. The "out of the box" promise rarely survives first contact with actual business requirements.

The platform becomes the constraint, not the capability. Every business-specific requirement that doesn't fit the vendor's model becomes a "customization project." Every competitive advantage you want to build requires fighting against what the platform assumes you should do.

Salesforce implementation costs in 2026 typically range from $10,000 to over $200,000 for complex projects¹ — and that's just the implementation. Before the ongoing customization even begins. One analysis firm warns that "many projects that started at $50K ended up at $150K or more."²

The Stupidity Tax Formula

Let's name this pattern with a formula — because naming it makes it visible, and visibility is the first step to escape.

The Real Cost Breakdown

Let's make the economics visceral with a real example. This is what platform ownership actually costs when you count everything.

The consultant rates alone tell the story: junior Salesforce consultants charge $60 to $100 per hour, mid-level $100 to $150 per hour, and senior consultants $150 to $250 per hour.³ Professional consulting firms handling end-to-end implementation charge $90 to $300 per hour.⁴

The average Salesforce administrator salary is around $85,000 annually, with U.S. salaries ranging from $80,000 to over $130,000.⁵ Freelance rates range from $80 to $150 per hour. That's the cost of institutional archaeology — maintaining tribal knowledge of "why the system works this way."

Key person risk compounds this: if your admin leaves, knowledge walks out the door. No version control, no documentation, no tests. Just oral tradition about which workflow triggers which automation.

Where the Money Actually Goes

Follow the dollar to understand why this is a trap. The platform vendor's moat is your prison.

The No-Leverage Trap

Here's the thesis that will reshape how you think about platform investment: where does your customisation dollar compound?

Platform configuration returns are linear, diminishing, and locked-in. Every dollar you pour into platform configuration:

• ✗ Doesn't benefit from model improvements
• ✗ Doesn't compound with your team's learning
• ✗ Doesn't transfer to your next system
• ✗ Locks you deeper into someone else's roadmap

AI can only help a little bit with Salesforce in practice. Platform customisation sits where AI is weakest: proprietary configuration languages that aren't in AI training data, closed ecosystems with no API access for AI tools, and real-time configuration changes that are high-stakes, one-shot interactions.

The Escalating Trap

It gets worse over time, not better. SaaS inflation compounds the stupidity tax every year.

SaaS inflation is now nearly 5x higher than the standard market inflation rate of G7 countries — and is ever increasing whilst the consumer inflation index drops.⁶ B2B pricing surged approximately 11.4% compared to 2024, versus a 2.7% average market inflation rate.⁷

The compound effect is brutal: platform licenses rise 10-12% annually, consultant rates 5-10%, admin salaries 3-5%, and integration maintenance scales with complexity. Total platform spend compounds at 8-15% annually.

Meanwhile, AI development costs have collapsed 70-90%. The economic inversion is complete: custom AI development costs have plummeted while SaaS prices rise.

"The plumbing — auth, Stripe — is real-time, efficient, cheap. We aren't customising it anyway. If it's cheap enough and we aren't customising, sure, buy it."

This Isn't Anti-SaaS

Chapter 1 was provocative. Now let's earn the credibility. Some software absolutely should stay SaaS.

The question isn't "buy or build?" — it's "where does customisation burden sit?"

The problem isn't SaaS itself. The problem is that platform vendors extended the SaaS promise to categories where it doesn't work. They took a model that works brilliantly for payments and authentication, and tried to apply it to CRM and workflow management.

The distinction that matters:

• ✓ Buying software works when you're plugging in, not fitting
• ✗ Building software becomes necessary when customisation burden exceeds benefit

What shifted: AI collapsed build costs, so the threshold moved. What was once clearly "buy" territory is now often "build" territory.⁹

Tier 1: Commodity Plumbing — Keep Buying

This tier stays SaaS because AI can't beat their operational depth. These vendors have something you'll never replicate: global infrastructure, regulatory relationships, and operational muscle built over decades.

Why doesn't AI change this? These systems require operational depth that AI can't replicate:

The value isn't in the code — it's in the operational muscle. Building this would cost more than subscribing forever.

Tier 2: Horizontal Platforms — The Flip Zone

This is where the economics have inverted. This is where your customisation dollars have zero AI leverage. This is the flip zone.

The economics are brutal. For a typical Tier 2 platform:

• • Platform license: $100K-200K/year
• • Implementation: $300K-1M (amortised)¹⁰
• • Internal admins: $150K-300K/year¹¹
• • Consultant retainer: $50K-150K/year¹²
• • Integration maintenance: $50K-100K/year

Total ownership: 3-5x the license fee.¹³ We saw this in Chapter 1: a $200K Salesforce deployment costs nearly $1M when you count everything.

Why does AI change this? Spec-driven development: AI does 80% of code generation.¹⁴ Platform configuration: AI does ~5% (proprietary languages, closed ecosystems). Same dollar, 16x difference in AI leverage. The translation layer was the expensive part — AI eliminates it for code, not for config.

Tier 3: Industry Verticals — Also Flip Zone

Industry-specific platforms have the same problem as Tier 2, with extra deception. They promise specificity but deliver averages.

The core platform is still 60-70% generic — the "vertical" is just a skin.¹⁵ Your industry specifics don't match their average, so you're back to customisation work. But now you're paying premium pricing because "industry expertise."

Why "industry-specific" is often worse:

• • You're STILL customising, just with industry-specific constraints
• • The platform's "best practices" may not match your actual practices
• • Switching costs are higher (industry data formats, regulatory compliance)
• • Fewer alternatives within the vertical = less negotiating leverage

The Decision Heuristic: The 50% Threshold

Let's make this concrete. Here's a rule you can apply to your own stack:

The Three Questions to Ask

Operationalise the framework with these diagnostic questions. Apply them to each platform in your stack.

The Cognition Ladder Connection

The Three Tiers map to a broader framework about where AI creates value.

"This is why Agile got so popular — it's a way to sort of deal with the 'it's too hard' problem. Too complex. Too much technical debt. Just focus on a tiny thing and try to get that done."

A Coping Mechanism, Not a Solution

Here's an uncomfortable truth about Agile methodology: it was never a solution. It was a coping mechanism.

The standard origin story tells us Agile emerged as a response to waterfall failures. The deeper truth? Agile emerged because software got too complex to manage. "It's too hard" became the unstated premise. The answer: just focus on a tiny thing and try to get that done.

This matters for platform configuration because it has the same complexity problem. But platform config didn't inherit the coping mechanisms that code developed. Agile, CI/CD, testing, version control — all these emerged from code complexity. Platform configuration inherited the complexity without the solutions.

When artificial intelligence can generate implementations from specifications in minutes rather than months, the cost of iteration approaches zero.⁹ Spec-driven AI development makes complexity manageable again. And that changes everything.

Two Types of Technical Debt — Different Futures

Technical debt isn't one thing. There are two distinct types with completely different trajectories.

The Complete Comparison

Let's make the contrast explicit. This table captures why platform configuration debt spirals while codebase debt can be managed.

Signs You Have Platform Configuration Debt

These symptoms show up in every organisation with significant platform customisation. How many do you recognise?

Common symptoms include: proliferating custom fields, conflicting automations, manual spreadsheet workarounds, brittle integrations, and slow admin cycles for simple requests.¹⁰

Why Code Has Solutions (And Platforms Don't)

The tools we have for code didn't appear magically — they solved real problems. Platform configuration lacks these tools because vendors didn't build them.

50 years of engineering discipline for code; 0 years for platform config. These disciplines emerged because code complexity demanded them. Platform configuration inherited the complexity without the solutions.

What AI Can Do for Code (But Not Config)

This connects directly to the leverage thesis. AI creates massive value for code because it has the right "shape" for AI assistance. Platform configuration doesn't.

The New Development Model

If Agile was coping with "too complex," what happens when spec-driven AI makes complexity manageable? A new model emerges.

Why can't platform configuration adopt this model?

• ✗ No spec language for platform configuration
• ✗ No way to regenerate config from spec
• ✗ No automated evaluation for config changes
• ✗ Stuck with "hope and archaeology"

The Diverging Paths

The two types of debt have completely different futures. Only one has a path to improvement.

"I rapidly went from about 80% manual+autocomplete coding and 20% agents in November to 80% agent coding and 20% edits+touchups in December. i.e. I really am mostly programming in English now."

The Paradigm Shift: Karpathy's Confession

When elite programmers change their 20-year workflow in weeks, the ground has shifted. This isn't future speculation — it's current practice.

"This is easily the biggest change to my basic coding workflow in ~2 decades of programming and it happened over the course of a few weeks." The shift happened in weeks, not years. Elite programmers don't change 20-year habits for marginal improvements.

Most telling: "I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year." Even Karpathy feels behind. "A failure to claim the boost feels decidedly like skill issue."

If the best programmers feel they're not capturing the full advantage, what about platform configuration teams?

The Evidence Is Everywhere

Karpathy isn't alone. The data is consistent across sources.

The Core Question: Where Does Your Dollar Compound?

It's time to reframe the build vs buy question as a leverage question.

Why This Just Happened

Why is January 2026 different from January 2024? Model capabilities crossed a threshold.

Programming is no longer just about languages, data structures, and algorithms. A completely new layer has been added on top. Today's leverage comes from knowing how to prompt and orchestrate AI agents, give them memory and context, and connect them to codebases via tools.

The 20x-100x Claim

Let's quantify the leverage difference. Where does "20x to 100x more effective" come from?

The Economic Inversion

SaaS costs are rising while build costs have collapsed. The economics have flipped.

The Leverage Test Applied

Let's make the test actionable. For any software category, ask three questions:

The One-Liner

"You don't start from zero. You start from 'what we actually built, expressed as platform configuration.' Export that, translate to spec, regenerate as software you own."

The Sunk Cost Reframe

The standard view: Sunk cost is wasted money, don't let it trap you. The new view: Sunk cost is captured requirements, use it as an asset.

Organisations resist platform escape because "we've invested so much." But the investment isn't wasted — it's encoded knowledge. Your current configuration documents exactly what you need. The archaeology has been done; the requirements have been captured.

The money is spent either way. The question is: what do you extract from it?

What Your Configuration Actually Documents

Every configuration element you've built represents a requirement you discovered. Let's make that mapping explicit.

The Extraction Process

Here's the strategic pattern for extracting your requirements from platform configuration.

Why AI Excels at This Translation

AI is good at exactly this kind of transformation.²⁹ Structure → Structure is an AI sweet spot.

Existing Behaviour Defines Acceptance Criteria

Here's a counterintuitive principle: Your current system, with all its quirks, is the acceptance test.³⁰ If the new system does what the old one did, it's correct.

Pain Points as Explicit Constraints

The things that frustrate users are requirements too. Capture them so the new system doesn't repeat them.

The Spec Format

What does the extracted spec actually look like? Here's the high-level structure.

Why this format matters: It's platform-agnostic. It's AI-consumable for regeneration.³¹ It's human-readable for review. It's version-controllable.

The Liberation Moment

Once the spec is extracted, you're free. The platform no longer owns your requirements.

"Sprints used to be weeks. Now they're nights."

The Time Compression

What used to take weeks now takes hours. This isn't incremental improvement — it's category change.

Why Overnight Works: The Batch Advantage

Overnight isn't just "working at night" — it's a different operating model. Batch processing unlocks capabilities real-time can't access.

Progressive Resolution Overnight

Work coarse-to-fine — stabilise structure before committing to detail.³³ The Jenga Problem: High-resolution changes cascade into unexpected breakage. Solution: Lock each layer before advancing.

The Agent Army Model

Not one agent — many agents in parallel. Scale the overnight capacity.

What Overnight Produces

The artifacts that appear in your morning inbox.

Governance Built-In

Overnight sprints are MORE auditable than platform changes. Your AI development inherits CI/CD discipline.³⁵

The Availability Multiplier

Your Salesforce admin is awake 40 hours a week. Your AI team is awake 168.

The Direct Comparison

"After ~5 patches, regeneration almost always wins economically."

The Economics Inversion

The old rules made sense when generation was expensive. Those rules have flipped.³⁹

Maintenance is now MORE expensive than generation.

The Crossover Rule

The compound effect: Each patch adds complexity. Complexity makes future patches harder.⁴⁰ The 10th patch is 3-4x harder than the 1st. Regeneration cost stays constant.

Platform Configuration Can't Regenerate

This is the structural trap. Platform config has patching as the ONLY option.

Model Upgrades = Free Improvement

Regeneration from spec captures model improvements automatically. Platform config gets nothing.

The Delete Test

The Kernel-First Discipline

The Diverging Trajectories

The Compound Advantage

Regeneration economics compound over time. This is the long-term leverage argument.

"You didn't become a sales ops leader to spend 60% of your time on admin archaeology."

The RevOps Reality

Let's paint the specific pain of CRM-heavy roles. Does this sound familiar?

"Industry solutions aren't custom enough — you spend a fortune fitting them correctly."

The Promise vs The Reality

How the Pattern Plays Out

Why Industry Verticals Are Often Worse

Counter-intuitive: Industry-specific can be harder than horizontal. Here's why.

The Leverage Test for Industry Verticals

The "Built for Your Industry" Deceptions

The Spec-Driven Alternative

Why Your Expertise Wins

Your team has the industry expertise that matters. That expertise should go into YOUR spec — not into hoping the vendor got it right.

"Enterprises start with platform debt and need to escape. Solo operators can start with leverage."

The Clean Slate Advantage

Solo operators and small teams can skip the escape phase entirely. Starting fresh with spec-driven development = pure leverage from day one.

Economies of Specificity

The economic advantage has inverted from economies of scale to economies of specificity.⁵¹

The Coordination Cost Advantage

Small teams avoid the overhead that kills large org AI adoption. Speed of learning beats size.⁵⁴

The Three Tiers for Small Teams

Same framework, different recommendations. Skip Tier 2-3 entirely, go straight to build.

Full AI Leverage from Dollar One

Every dollar compounds from the start. No migration cost, no platform debt.

What Solo Operators Actually Need

It's less than you think.

When to Go Spec-Driven from Day One

"Stop funding your vendor's moat. Start funding your AI leverage."
