A closer look at what we built
Simple on
the surface.
Serious
underneath.
A whole coaching operation, behind a text.
Meet the product, the knowledge, and the craft that make KiloClub.
care & craft
02 / The product
Built and testedOne text.
An entire system
behind it.
Members see a conversation.
Underneath: billing, identity, coaching memory, team workflows and delivery controls.
A little support.
A lot of momentum.
One connected member journey.
Trainer-branded pages, checkout, consent and a welcome screen connect to first-text membership activation.
Yes, we thought about that.
But what happens when…
Event claims and idempotency checks handle duplicates so a provider retry doesn’t become duplicate processing.
Beyond the happy path.
Duplicate webhooks, failed deliveries, refunds and dispute holds each have deliberate handling.
A memory for the small wins.
Goals, confirmed check-ins and workout history stay connected. Personal bests even account for pounds and kilograms.
03 / The knowledge
Research made usableKnowledge.
With receipts.
A structured coaching library with source links, scope boundaries, and a way to test the answers it supports.
We turned research into guidance the product can select, check, and use. Source links, review notes and scope boundaries travel with the guidance.
Among the sources referenced. No affiliation or endorsement.
A method behind the movement.
Starting from zero. Progressive overload and effort. Soreness vs pain. Actual pages, built for actual coaching questions.
Measured, then improved
We test the judgment
behind the draft.
Recorded evaluation · October 2, 2026
Knowledge pages are drafts awaiting credentialed review. These are authored references and test scenarios, not customer records.
04 / The care
Safeguards in the implementationTrust lives
in the details.
Coaching carries personal context. Access, privacy and human judgment are part of the architecture.
Pick a layer to look inside.
A login is only the beginning.
Staff access checks active membership and role. Client sessions use hashed tokens, with rate limits around sensitive actions.
AI prepares.
A person decides.
- 01Relevant context
- 02Scope & safety checks
- 03Draft reply
- 04Human review & send
AI drafting is opt-in, and a draft never sends on its own. These are built-in safeguards, not an independent security certification.
05 / The craft
The work behind the workThe details add up.
So does the work.
recorded commits
A history of decisions and improvements.
versioned test files
Tests across the product’s workflows.
database migrations
A versioned foundation for the data model.
The edge cases
got attention, too.
Automated verification. Checks for secrets, types, tests and production builds are part of the repo.
Room to rehearse. An isolated local environment separates test fixtures from the shared database.
A real design system. Shared typography, color and interaction rules connect the public site to daily workspaces.
For the technically curious
A clear stack.
Deliberate boundaries.
