Buy a Training Platform or Build Your Own Program? The Real Math
The Question That Shows Up Around 100 Employees
Somewhere around a hundred employees, an owner loses the ability to personally develop everyone. Supervisors get promoted without preparation, sales ramp gets inconsistent, and someone finally asks the structural question: do we build training in-house — hire a trainer, create our own program — or buy it? Both answers can be right. The problem is that the comparison is almost never run honestly, because each side hides different line items. This is the math I walk owners through, with the hidden lines put back in.
What 'Build' Actually Costs
The visible line is the trainer's salary. The hidden lines are bigger. Content creation is brutally time-intensive: a single hour of decent workshop material takes many hours of development, and a trainer covering leadership, sales, compliance, and professional skills is building four curricula at once. Then there is everything around the content — scheduling, enrollment, chasing completions, reporting — which silently consumes a large share of the role. Expect the first six to twelve months to go to building rather than training anyone. And the structural risk almost nobody prices: one person is your entire function. When they leave, the program, the materials, and the momentum usually leave with them.
What 'Buy' Actually Costs
For scale: Training Magazine's 2025 survey reports that midsize companies spend $1.6M a year on training and small companies spend $333K. Against that backdrop, here is one concrete, public data point — Thrive's published pricing: a Compliance Library at $0 for the whole organization, a Knowledge Library at $599 per user per year for all 170+ courses, and a Skills & Careers tier from $999 that includes unlimited live expert-facilitated workshops running 20+ times a month, with everything month-to-month. But the buy side hides line items too, and you should hunt for them in any vendor's offer including ours: admin work the vendor quietly leaves with you, per-seat pricing that compounds as you grow, and generic content that may not fit your industry. Ask every vendor which of those three applies. The honest ones will tell you.
The Comparison Most Vendors Will Not Show You
Cost per seat is the wrong denominator. The number that matters is cost per employee who actually completed the training and changed behavior — because that is the thing you are buying. Run it on anything you already own and the rankings reorder fast: a cheap library that nobody finishes is the most expensive option in the building per developed employee, and a pricier option with real completion can be the cheapest. This one denominator change is the single most useful correction to the buy-versus-build math, and it cuts against vendors and DIY plans alike.
When Building Wins
I will argue against my own product here, because the honest cases for building are real. Build when training is your product — customers pay for your expertise, so the curriculum is an asset. Build when your competitive advantage lives in specialized internal knowledge that no outside facilitator can teach. Build when you have genuine scale — enough employees that dedicated headcount math works without rounding in its favor. And build when you already have the rare thing: a committed internal operator with protected hours who wants to own it. If none of those four describes you, building is a hobby with a salary attached.
When Buying Wins
Buy when there is no internal owner with real hours — the most common situation in companies without an L&D team, and the one where DIY programs reliably die. Buy when you need live facilitation but cannot keep a facilitator busy full-time; a platform running 20+ workshops a month spreads that cost across many companies in a way you cannot replicate alone. Buy when speed matters: a turnkey function is delivering in week one, while a build is still writing its first curriculum. And buy when what you need is the standard canon — management, feedback, sales, compliance — that is the same at your company as everywhere else. Paying someone to re-derive it in-house is paying twice.
Run It Like an Experiment, Not a Conversion
You do not have to be right up front; you have to be measurable. Pick one team and one quarter. Write down the behavior you expect to change and the number you expect to move — completion of a cohort, time-to-productivity for new supervisors, whatever maps to the problem you actually have. Run the smallest version of buy (one tier, one team) or build (one internal workshop, one owner), compare the result to the prediction, and expand only what the evidence supports. The owners I see get this right treat the first 90 days as a test they designed, not a commitment they defend.
