How the agent runs it

Clients complete a structured intake form describing their injury, sport, pain level, and recovery goals; the orchestrator agent routes the submission to the Protocol Agent, which generates a fully personalized, phase-gated rehab program with exercises, progressions, load tolerances, and red-flag warnings. The Delivery Agent compiles a branded PDF and an interactive Notion dashboard, then the Revenue Agent handles upsell sequencing for follow-up check-in plans, while the Support Agent answers client questions autonomously within defined clinical scope boundaries.

Who this is for

Ideal for a solo founder with a background in sports, fitness, or physical therapy who understands rehab language well enough to audit outputs but does not want to do 1-on-1 coaching. A personal trainer, exercise science graduate, or former collegiate athlete who is comfortable setting up Stripe, Typeform, and Notion in a weekend would find this straightforward to launch and operate.

Market opportunity

The global sports medicine market is valued above $7 billion and growing at roughly 6% annually, yet the vast majority of amateur athletes — weekend warriors, recreational runners, CrossFit athletes — never access formal PT due to cost or insurance friction. The rise of remote health services and the normalization of digital wellness products post-2020 has primed this audience to pay for credible, immediate, self-serve recovery guidance without a clinic visit.

Boss agent: APEX Orchestrator

APEX receives every completed intake, scores it for tier classification and red-flag indicators, assigns it to the correct specialist agent, enforces SLA timers (delivery within 15 minutes), and logs all outputs to an audit trail for owner review.

  • No protocol is delivered for Tier 3 post-surgical cases without explicit human owner review flag being set
  • All outputs must include mandatory red-flag language block before the first exercise instruction
  • Delivery Agent cannot send final PDF until Protocol Agent has passed internal completeness check scoring above 0.85

The agent team

🤖
INTAKE Agent
Monitors Typeform webhook, parses and normalizes every submission into a structured JSON record, flags incomplete or ambiguous answers for automated clarification follow-up via SendGrid before routing to APEX.
🤖
PROTOCOL Agent
Owns the end-to-end creation of the personalized rehab plan: selects appropriate exercises for each phase, sets rep/set/load/frequency parameters, writes coaching cues, embeds progression criteria, and appends red-flag escalation instructions.
🤖
DELIVERY Agent
Converts the protocol JSON into a branded PDF report and a structured Notion client dashboard, attaches the client's name and injury summary to both, and triggers the SendGrid delivery email with access links within the SLA window.
🤖
REVENUE Agent
Manages post-delivery email sequences: sends a 7-day check-in prompt, pitches the monthly subscription update plan at day 10, and triggers a re-engagement offer if the client has not opened their Notion dashboard within 48 hours of delivery.
🤖
SUPPORT Agent
Answers inbound client questions via email within defined clinical scope — exercise clarifications, substitution requests, scheduling adjustments — and escalates any symptom-worsening reports or medical questions immediately to the human owner queue.

Human touchpoints

// the only things that still need you

  • 👤 Legal signature on terms of service, disclaimer pages, and any affiliate PT review partnership agreements
  • 👤 Manual review and approval of every Tier 3 post-surgical protocol before delivery, as enforced by APEX's hard rule
  • 👤 Resolution of escalated support tickets involving reported symptom worsening, potential adverse events, or requests for refunds above a threshold amount
  • 👤 Periodic audit (weekly, 30 minutes) of a random sample of delivered protocols to verify quality, scope compliance, and brand voice consistency

Monetization

Flat-fee protocol purchases at $49–$149 per plan depending on complexity tier, plus a $29/mo subscription for monthly check-in protocol updates and Q&A access. A licensed physical therapist affiliate review add-on at $79 unlocks a human PT's async signature for clients who need it.

Key risks

  • A client follows a protocol incorrectly and aggravates their injury, creating liability exposure if disclaimers and scope-of-practice language are not legally airtight from day one.
  • Platform saturation risk: low barrier to imitation means a competitor can clone the intake-to-PDF workflow within days, so brand trust and protocol depth must be the durable moat.

Getting started

  1. 1
    Define three injury protocol tiers clearly
    Map out Tier 1 (acute soft tissue, e.g. ankle sprains), Tier 2 (overuse injuries, e.g. tennis elbow, runner's knee), and Tier 3 (post-surgical, cleared for home rehab). This scoping protects you legally and trains your Protocol Agent's decision boundaries from the start.
  2. 2
    Build the intake form in Typeform
    Create a 12–15 question intake covering injury type, sport, weekly activity load, pain scale, mobility restrictions, and any surgical history. This structured input is the raw material every downstream agent depends on — garbage in means garbage out.
  3. 3
    Draft the Protocol Agent's master prompt library
    Write Claude system prompts for each injury tier that enforce phase-gated progressions (acute, sub-acute, functional return), embed mandatory red-flag escalation language, and cite exercise science rationale inline. Test with 10 synthetic intakes before going live.
  4. 4
    Set up Stripe and Notion delivery pipeline
    Connect Stripe Checkout to the Typeform completion webhook, then automate Notion page creation via API so each paying client gets a private, branded dashboard within 90 seconds of payment. This is the WOW moment that justifies the price point.
  5. 5
    Publish a legally reviewed disclaimer page
    Have a real attorney (one-time cost, ~$300–$500) review and draft your scope-of-service disclaimer, not-a-replacement-for-PT language, and terms of service before your first paid client. This is the single non-negotiable human investment before launch.
