From 5-Year Roadmap to Reality: AI Didn't Just Accelerate Development. It Changed the Business.
In 2021, building PF TECH required an estimated $300,000+ in startup capital for product development alone — before marketing, sales, or operations. By 2025, that estimate was essentially obsolete. But the development story is actually the least interesting part of what AI has done to this business. The real shift is in the operating model.

In 2021, when I was planning what would eventually become PF TECH, I put together a capital budget for building TERN. Product development alone: north of $300,000. That was before marketing, sales infrastructure, operational overhead, or the cost of managing the business itself. Those were separate line items, each requiring either hired staff or paid agencies.
I looked at that number and concluded the timeline was "someday, if the organization achieves significant scale." A real plan, but a slow one.
By 2025, I had built the core of what that plan described. The product development estimate did not decrease. It essentially disappeared. And it turns out that development speed is actually the least interesting part of what happened.
The Numbers That Actually Matter
Not a development story. An operating-model story.
Chapter 01 of 03
Skip chapter introThe headlines tend to focus on development speed: AI lets one person build what used to require a team. Features ship in days instead of months. That is true, and the implications for product development are significant. But it is not the main story.
What AI has done to the economics of PF TECH is an operating model story, not primarily a development story. The compression extends across every function a business needs to run, and the cumulative effect of that compression is structural rather than incremental.
Here is what those budget lines look like in 2025:
- Product development: AI-assisted engineering made the $300,000 estimate functionally obsolete. Custom websites in under a week at under $100 in compute. Core integrations that previously took two weeks to configure now deploy in a day. Planning tools built in eight hours for less than $40 in compute, replacing $2,000/month in labour overhead.
- Marketing: I used to pay a marketing and Google Ads agency to manage our digital presence. I have replaced that engagement with custom AI agents that handle content strategy, ad optimization, and performance monitoring — continuously, not on a monthly billing cycle.
- Executive operations: Our entire executive assistant function — scheduling, inbox management, meeting preparation, follow-up coordination — is now handled by agents I built. Tasks that used to require dedicated administrative support now run automatically.
- Managed IT: We have significantly reduced our reliance on managed IT support by building internal automation for monitoring, incident response, and routine maintenance.
- Sales: Custom AI agents for prospect research, proposal generation, and follow-up sequencing.
- Level 1 support: The website's AI chat assistant handles first-contact questions and escalation routing without human intervention.
- Digital media and web development: In-house, AI-assisted, at a fraction of the cost of the agency relationships we used to maintain.
This is not a story about one function getting faster. The cost structure of operating a knowledge-intensive business has been fundamentally restructured. The overhead that previously justified a minimum viable business size of several hundred thousand dollars annually is now accessible at a fraction of that cost.

What Remains Irreplaceable
AI compresses execution, not knowledge. The distinction is load-bearing.
Chapter 02 of 03
Skip chapter introHere is the part the AI productivity discourse tends to skip: the compression is not uniform.
AIcompressesexecution.
It does not compress knowledge. It accelerates the translation of expertise into working systems — but only if the expertise already exists.
The domain knowledge required to build TERN is not something AI can acquire or approximate — it has to be earned. Two decades, six operational domains:
- Non-profit fund accounting
- CRA compliance
- Grant management
- Donor reconciliation
- Payroll systems
- Governance practice
It can help someone with that knowledge build faster. It cannot substitute for the knowledge itself.
This is why training has become more important, not less, as AI tools have proliferated.
The tech giants have already made several of what might have been PF TECH's early product ideas obsolete. They will make more. General-purpose AI tools commoditize general-purpose problems at a pace that no small operator can match. The defensible position is not in building another general tool. It is in the specific intersection where general AI tools fail: the intersection of AI capability, information management discipline, non-profit operational knowledge, governance and risk frameworks, and sector-specific regulatory compliance.
That intersection is what PF TECH occupies, and what TERN is built for. It is also what the Mission Multiplier Program is designed to cultivate in practitioners across the sector.
Of non-profit domain knowledge AI cannot compress
Fund accounting, CRA compliance, grant management, donor reconciliation, governance. The force multiplier only works if there is force to multiply.
The Strategic Implication
The force multiplier only works if there is force to multiply.
Chapter 03 of 03
Skip chapter introThe force multiplier metaphor is accurate but incomplete. A force multiplier amplifies force in proportion to the force that is input. If the input is twenty years of sector-specific knowledge, the output is significant. If the input is general curiosity and no domain depth, the output is still general.
This is why the training and advisory work is now as central to the Multiplier Model as the technology itself. TERN's technical capabilities only matter if the practitioners using them understand what the outputs mean, what the governance requirements are, and how to interpret the data in the context of their specific organization's operational and regulatory situation.
The sector that will benefit most from AI is not the one that adopts the most tools. It is the one that builds the deepest competency at the intersection of AI capability and sector-specific knowledge. That competency does not come from a product. It comes from deliberate practice, ongoing learning, and the kind of peer community that compounds knowledge over time.
The sector that will benefit most from AI is not the one that adopts the most tools. It is the one that builds the deepest competency at the intersection of AI capability and sector-specific knowledge.

What I described as a five-year roadmap in 2021 is now a present-day reality. The harder question — and the one that matters more — is whether the sector is ready to use it.
Build the competency, not just the tool
The Mission Multiplier Program is for non-profit practitioners who understand that AI tools are only as powerful as the domain knowledge behind them. Monthly 90-minute workshops, small groups of 15–20, evolving curriculum, and first access to TERN capabilities as they launch.

Why the automation story needs a second chapter
There's a version of the AI-in-non-profits story being told right now that goes like this: AI will automate the tedious back-office work, free up your staff, and let you focus on your mission. That version is true — I believe it deeply and I'm building the tools to make it real. But there's a part of the story that isn't being told, and the gap between those two versions is where a lot of organizations are going to get hurt.

Resilience is a Verb: What the CPA Ontario Not-for-Profit Conference Revealed
Field Note · CPA Ontario NFP Conference 2025
In November 2025 I hosted the CPA Ontario Not-for-Profit Conference. The theme was Resilient Futures. Seven speakers, eight hours, topics ranging from AI adoption to board governance to front-line service delivery. What I took away was more urgent than the theme: the sector's biggest obstacle to building resilience is not funding or technical skills. It is the calculus that makes staying stuck feel safer than taking the next step.

Building a Better Engine: The PF TECH Origin Story
Origin Story · PF TECH
PF TECH didn't start at a whiteboard. It started in a filing cabinet — in 2013, watching a colleague print every email he received and file the paper copies in rows of cabinets along the wall. Nearly two decades later, that pattern is still the sector's central problem. Here's what I built because of it.
