How to build a coaching app — buy, custom, or branded?

The three categories and when each one wins. Why "purpose-built SaaS" (the third category most coaches don't know exists) is usually the right answer. Real numbers on custom-build cost, ongoing maintenance, and feature velocity.

Solo-coach economics

What an online coach actually earns at 25 / 50 / 100 clients

The real take-home math after Stripe fees + Trainerize per-client + branded-app costs + tax. Three coach archetypes (powerlifting, postpartum, hybrid). The pricing model that gets you to $200K take-home without 100+ clients.

HELM · Wealth-OS Essays

HELM — tax-aware portfolio decisions for solo HNW operators.

Wash sales across brokerages. QSBS. AMT after the SALT cap. Asset location. Aggregator security. Worked examples with real IRS sections cited. Educational only — not advice.

Architecture · Privacy

The aggregator problem: why we refuse to ask for your brokerage password.

How aggregator-based wealth tools work under the hood, what breaks when they fail (Plaid 2022 settlement cited), why HNW operators carry asymmetric risk, and the trade-offs of manual-first architecture both directions.

Tax · IRC §1091

The wash-sale rule applies across every brokerage you own.

Worked example with Schwab + spouse's Fidelity Roth IRA showing how a $20K disallowed loss can become permanently disallowed. Rev. Rul. 2008-5 cited. Three operational rules that prevent 90% of cross-account triggers.

QSBS §1202 — the most under-used tax break in tech compensation.

Tax · AMT · §55–§59

AMT after the SALT cap — a worked example for ISO exercise.

$400K W-2, 10K ISOs at $4 strike with $52 FMV → ~$130K AMT bite. The AMT credit (recoverable). The dual-basis problem on eventual sale. The disqualifying-disposition trap. Three operational rules for AMT-aware exercise.

Portfolio · Tax efficiency

Asset location vs asset allocation — the Bogleheads gap.

Allocation is what you own; location is which account holds it. Most FI calculators ignore location. 25-year worked example: ~$330K terminal-wealth gap from same allocation, different placement. The Roth-priority rule. Three contexts where the standard rule bends.

Operating model

Net worth is a lagging indicator. Here's the leading one.

By the time net worth changes, the decisions that drove it happened months or years ago. Five leading indicators that predict trajectory: savings rate × 12 · marginal-dollar deployment · cash cushion months · debt-paydown velocity · vesting-pipeline NPV.

Architecture · Privacy

What HELM has on you. The complete list.

A non-custodial wealth OS publishes its full data inventory — and the inventory of what it does NOT store. Most finance apps can't answer this question; HELM was built so it could. Plus: a five-question template you can take to any other finance app you're evaluating.

Tax · ESPP

Reading a 1099-B for ESPP, without a CPA.
