Portrait · Shuo YangRYCO · SoCal

30 years a software engineer, now also a licensed general contractor. Founding engineer at Textura — the construction-finance platform acquired by Oracle that processes billion-dollar monthly volume. Now runs RYCO, an ADU-focused shop in SoCal, where he runs his own back-office on the same system GCStack clients use.

GCStack is the system he built to run RYCO — productized for emerging ADU builders outside his market. He knows your numbers because they’re his numbers.

02 · What’s in the pilot · from what we run at RYCO

Everything you need to scale your ADU shop. One price. One deliverable.

Fig. 02

The pilot includes both the back-office we set up and the marketing engine we run. These aren’t products you pick between — they’re what’s in the single bundled pilot. No tier-shopping. No add-ons.

Marketing engineWe run your growth

We run your growth.

  • 01Original content for ads & organic, weekly cadence

  • 05Award-winning proposal craft
  • 06Weekly performance + lead-volume reporting

// Full intensity during the pilot until the lead-volume target hits.

Back-officeWe run your operations

We run your operations.

  • 01Project management system — we run it, you never touch it
  • 02Vendor-bill automation (AP)
  • 03AR invoicing + draw schedules
  • 04Expense tracking + job-cost reports
  • 05Automated phone system on your forwarded line

  • 07Your north-star metric — synced live, not month-end surprises

// Set up during the pilot. Runs through the retainer phase.

The deal

Everything above is included in the pilot price. Back-office is included for the pilot period — or runs on its own on a flat monthly retainer.

03 · Why GCStack

Most agencies have never been on a job site. We’ve poured foundations.

Fig. 03 · The moats

Two things no other agency can copy — because both require a licensed ADU builder who’s won and lost bids on his own name. We sell the outcome. The build stays with us.

Moat 01 — Award-winning proposals

Proposals that read like a contract worth signing.

Cover, budget structure, scope framing — done by a builder who’s been across the table from his own customers, on his own license, for years.

The craft is the moat. The signed contract is what we deliver.

Moat 02 — Exceptional tech

Tech that turns trust into leads at scale.

Homeowners buy from people they trust. Our tech earns that trust at scale — without burning your time.

Better leads. More signed contracts. We run marketing and back-office. We close the bids with you. You run the build.

The fragmented default

Bookkeeper. Receptionist. Agency. IT. No one signs your guarantee.

Fig. 04

What the patchwork stack actually delivers — and why an integrated bundle is the only way to put $1M signed on the line.

Fragmented stack

Four vendors who don’t talk.

Bookkeeper, receptionist, marketing agency, IT. Four invoices, four logins — and none of them ever signed up to deliver signed contracts.

Lost bids

Generic proposals lose bids that should close.

A proposal built from a custom-home template, a budget that doesn’t speak ADU economics. The work was there — the document didn’t sell it.

Time bleed

More jobs. More admin. Same desk.

Sunday bookkeeping. Phone calls during site visits. New jobs stack invoices, vendor bills, and follow-ups onto the operator — until the integrated stack pulls it off your desk.

04 · Straight talk

How a builder would expect to be treated.

Fig. 05
Ad spend

Most agencies make money on your ad spend. We don’t.

Our fee is for the system we built running RYCO and now run for you. Your ads are your investment, passed through at cost.

0%vs. the typical 10–15% markup
SoCal

If you’re in SoCal, we won’t take you on.

Our RYCO operates there. We don’t compete with the prospects we’re supposed to help. Different lanes — honest about the conflict.

Builder proof — not a projection

We close ADU proposals at 3%. Industry range is 1–3%. Our team coaches you through every discovery call, proposal, and follow-up — until you’re hitting 3% too. That’s why we can guarantee it.

Competition doesn’t guarantee results. It’s not how much you spend on ads — it’s how effective they are. Most agencies bill for activity. We bill for outcome.
Who this is for

Built for ADU builders ready to grow. Not everyone.

Fig. 07 · ICP
Who this is for
  • + Production capacity — crew, subs, or PM bandwidth ready to absorb $1M+ in new contracts
  • + A real angle ready to amplify — niche, location, specialization, or heritage
  • + Coachable on the business side — daily 10-min + weekly 1-hour cadence
  • + Owner-operator who makes the call
  • + ADU-focused, or ready to focus
  • + Outside SoCal
Who this isn’t for
  • × No production capacity — can’t deliver what we’d sign
  • × No unique angle — marketing has nothing to anchor on
  • × Uncoachable — won’t follow the playbook or commit to the cadence
  • × Traditional shops that must maintain a back-office staff
  • × Multi-partner shops where coaching gets diluted by committee
  • × Non-ADU or SoCal builders — wrong fit
06 · Apply to work with us

Three criteria. We say no to most.

Fig. 08

Introductory pricing for our first wave of select clients — discussed on the discovery call, not on the web. We say no to most prospects, so the few we take we can guarantee. Pass all three and you’re in.

// Built by a builder — the criteria are the same ones we’d apply to our own shop.

01 Criterion

Production capacity

Crew, subs, or PM bandwidth ready to absorb $1M+ in new contracts. Solo or shop — doesn’t matter, as long as you can build what we sign.

02 Criterion

A real angle ready to amplify

A niche, location, specialization, or heritage — something the marketing engine can build content around. Without it, there’s nothing to anchor on.

03 Criterion

Coachable on the business side

Daily 10-min + weekly 1-hour cadence. You know your numbers — margin per ADU, monthly overhead — and you’ll follow the playbook. The guarantee math depends on it.

0 / 3 — tap each one that’s a yes
$1M signed. Guaranteed.

If you meet your written commitments and we don’t deliver $1M in signed ADU contracts during the engagement, full refund.

We run everything

Paid ads, organic social, client nurturing, detailed winning proposals, invoicing, expense tracking. Plus we coach you to 3% close.

Competitors don’t guarantee

Most agencies bill for activity. We bill for outcome. It’s not about how much you spend on ads — it’s about how effective they are.
