Jack Yen · Operator

Left corporate.
Built the
way out.

13 years in tech. October 2024 I planned my way to a layoff and walked out with severance. 18 months later: two physical-asset businesses, 20+ employees on the kitchen floor, custom software replacing the third-party stack — donut shop ops and property management both.

// the story

Six figures, stock vesting, five years of Sunday night.

13 years in tech. 6 companies. Six-figure salary, stock vesting. Every Sunday night I dreaded Monday and told myself it was just a season. I told myself for five years.

Then I made a decision. I didn't quit. I planned my way to a layoff in October 2024 and walked out with six-figure severance. By that point I had 5 STRs cashflowing and 12 months of savings stacked. Tech was deep in layoff cycles. I let the timing work.

Eighteen months later: 11 STR/MTR units across Hawaii, DFW, and Tampa. 7 donut shops in DFW. The first ops stack took 3 weeks because the off-the-shelf tools cost too much and still didn't fit a 4am deskless workforce.

// what i'm building

Two operating businesses. One software stack.

Donut shops, insurance housing, and the internal tools built because the third-party stack didn't fit.

01 / DONUTS

Golden Glaze 🍩

PE-style rollup. Reg D 506(b).

7 donut shops across DFW. 20+ employees, most of them not sitting at laptops. The first problem wasn't strategy — it was getting daily checkins, schedules, inventory, cash counts, and investor updates out of tools built for desk workers.

7 shops · 20+ employees · GP/LP fund structure
02 / HOUSING

FlexStay Housing

Own portfolio + managing others'.

11 STR/MTR units across Hawaii, DFW, and Tampa. Most bookings are insurance housing: families displaced by fire, flood, or a contractor who missed the date. Not passive. Not vacation-content. Just housing with operational drag.

11 units · STR + MTR · Own + managed properties
03 / SOFTWARE

Golden Ops

Comprehensive QSR ops tooling.

Built to run Golden Glaze because the third-party stack was expensive and still missed the floor-level work. Daily checkins, scheduling, inventory, cash reconciliation, investor dashboards, and alerts — 7 modules across 7 locations. First version shipped in 3 weeks.

7 modules · 7 locations · Replaced ~$60K/yr in third-party tools
04 / SOFTWARE

FlexStay Ops

Multi-market property management.

Built to run FlexStay Housing because the PM stack was built for vacation rentals, not insurance housing or multi-market portfolios. Guest messaging, pricing logic, turnover coordination, multi-market dashboards. Currently building inventory management and guest messaging modules.

// the ai workforce

AI agents on the floor. Trained, not just deployed.

Most "AI for SMB" stops at a chatbot. Mine doesn't. I run persistent AI agents that observe real operations 24/7, build per-store knowledge bases like new employees on shadow shifts, and graduate through a promotion ladder before they're allowed to talk to anyone outside a private review channel. It's an org chart, not a feature.

A1 / TRAINING

Promotion ladder

Observe → shadow → limited → steady-state.

Each agent ships in observation phase. Daily digests into a private review channel. No public messages until I explicitly promote. Same way I'd promote a shift lead to GM — earned, not automatic.

4 phases · Explicit promotion · No self-promotion
A2 / KNOWLEDGE

Trained like an employee

Real shadow shifts. Real glossary.

Per-store profiles. Manager voice. Glossary of internal terms. Escalation patterns. Daily ingestion from Discord, email, POS, QuickBooks, and manager check-ins. The pipeline builds context the way shadow shifts do.

Per-store KB · Multi-source ingestion · Persistent memory
A3 / SCOPE

Authorized talkers list

Explicit boundaries. Like any new hire.

Who the agent can talk to is a list. What it can commit (no discounts, no menu changes, no hiring, no vendor terms) is a list. Same constraints you'd give a new employee on day one — written down, enforced in code.

Allowlist · Hard rules · Audit-ready
A4 / WORK

Front-of-house operations

Not a chatbot. Operating staff.

Daily ops digests. Google review responses with voice guardrails. Catering order processing. B2B outreach drafts. Wholesale lead pipeline. Each task graduated explicitly when the agent earns it.
