Sites that are actually running businesses.

Every entry below is live and in production. Each one lists the full breakdown — what the front-end does, what the systems behind it do, and how leads are captured and followed up.

Live Since 2024

alot.land

A land investing business — acquiring, subdividing, and selling rural and residential land. Not a client project: it's the company Goldstone runs, and the reason most of the land tooling exists.

alot.land is the proof. It's a production site running real acquisition traffic, backed by the same stack Goldstone sells — and the deal-analysis apps in the investor bundle were all built to serve it first.

Goldstone didn’t build alot.land for a client. We built it for ourselves, and it’s been running acquisitions ever since.

That matters more than a portfolio piece normally would. The tooling in the investor package — due diligence, parcel research, subdivide analysis — exists because this business needed it. Every one of those apps was used on a real deal before it was ever offered to anyone else.

Front-end

  • Seller-facing acquisition funnel built to convert cold land owners
  • Property listing pages with photo galleries and location context
  • Offer request and property submission forms
  • Buyer list capture for disposition
  • Static-rendered and mobile-first — fast on rural cell service
  • Self-editable content, listings, and pages through a git-backed admin

Back-end & systems

  • Git-based CMS — every content change is a versioned, revertible commit
  • Form submissions captured and routed without a third-party form service
  • Automated image optimization at build time
  • Multiple sites served from a single monorepo
  • Continuous deploy on push, with atomic rollbacks

CRM & lead handling

  • Lead capture wired from every form on the site into one pipeline
  • Automated first-response so inbound seller leads don't sit cold
  • Follow-up sequences that continue until the lead replies
  • Source tracking to attribute leads back to campaign and page

Software

Applications we've built and run.

5 working tools in production. Most sit behind a login because they run real deals and real operations — one is open if you want to try it.

Deal underwriting

Private tool

Minor Subdivide Analyzer

Underwrites a minor-subdivide deal end to end — split scenarios against cost and exit assumptions — and turns the result into an investor-ready deck. It's the tool we run our own acquisitions through.

  • Full financial model with per-scenario split, cost, and exit math
  • Deal flags that surface the assumptions doing the heavy lifting
  • Charted output built for showing an investor, not just an analyst
  • Unit-tested calculations locked to the original underwriting model

Comps & valuation

Try it

Redfin Comps Puller

Pulls vacant-land comparable sales, computes $/acre statistics, and exports comps that feed straight into the Exit Plan Calculators. Search by county, city, ZIP, or a radius around a map pin.

  • $/acre statistics computed across a chosen acreage band
  • Location search by county, city, ZIP, or radius around a point
  • Exports comps JSON directly into the Minor Subdivide Analyzer
  • Falls back to an assisted pull rather than failing silently when blocked

Multifamily underwriting

Private tool

MFDA — Multifamily Deal Analyzer

Takes the land underwriting model into multifamily: active and sold 2–20 unit properties across Arizona and Tennessee, running through a shared listing adapter so new data sources plug in without a rewrite.

  • Active and sold multifamily comparables across AZ and TN
  • Shared listing-source adapter so new data providers slot in
  • Magic-link auth with per-user data isolation

Parcel research

Private tool

Land Scout

Finds and qualifies parcels, works out highest-and-best use, and turns a rough sketch into a plan — the research step before a deal is worth underwriting at all.

  • Parcel search and qualification without stitching together county sites
  • Highest-and-best-use analysis on a candidate parcel
  • Sketch-to-plan generation for split concepts
Next.js TypeScript Supabase

Operations

Private tool

Time Audit

Logs activities against value tiers — $10K, $1K, $10–99, and $0 per hour — so you can see where the week actually went instead of where you assume it went. Built because running several businesses made the question urgent.

  • Every activity logged against a dollar-per-hour value tier
  • Weekly breakdown of where the time actually went
  • Reflection prompts that turn the data into a decision
  • History synced across devices, private to the signed-in user
