Operating method

Capital follows evidence. Not enthusiasm.

LifeGex is a parent company, not a fund and not an agency. Its only durable asset is a repeatable way to decide what to build next and what to stop. That decision is made at gates, against artifacts.

Model Stage-gated Portfolio 4 ventures Rule Artifact or nothing

Five gates, one question each

A gate is not a milestone and not a date. It is a question that can be answered with something a stranger could inspect. Until it is, the venture stays where it is.

Problem

Is this a real, frequent, expensive friction?

Evidence: interviews, observed behaviour, and a workaround people already pay for in time or money. A market-size slide does not pass this gate.

Unlocks Research time. Nothing else. Today CareTrip, StudyBase
01

Build

Can we make the smallest surface that resolves it?

Evidence: a working build in isolated QA, with named surfaces and a recorded version. Screenshots alone are not a build.

Unlocks QA budget and a private preview. Today PoseLane (private QA)
02

Pilot

Will strangers use it without being asked?

Evidence: real users outside the team, repeat usage, and a retention cohort that survives the novelty. Internal demos are excluded.

Unlocks Pilot capital. Today EatCue (pilot preparation)
03

Economics

Does a transaction cover its own cost?

Evidence: paid transactions, contribution margin, and a unit of growth that can be bought again. “It would work at scale” is not evidence.

Unlocks Scale capital. Today Not reached by any venture
04

Scale

Does acquisition repeat without heroics?

Evidence: a channel that works more than once, and shared modules that lower the cost of the next venture. Until then, expansion is a story, not a plan.

Unlocks Portfolio expansion. Today Not reached

What we refuse to do

Founder & operator, LifeGex

LifeGex is founder-led and operated from Vietnam. I write the gate sheets, review the builds, and decide where capital goes. The rule I hold myself to is simple: publish the gap before someone else finds it.

No advisory board is listed on this page. If one is formed, it will appear here with a name and a role rather than a logo wall.

The method only counts if it is visible.

Every gate answer that exists today is recorded in the ledger, including the rows with nothing in them. If the ledger and this page ever disagree, the ledger wins.
