We design and build the sites, dashboards, and data infrastructure that small businesses turn to when off-the-shelf tools start costing them more than they save. Then we stay on as your engineering partner — monthly retainer, real on-call.

Manifesto

Off-the-shelf gets you launched. Custom is what keeps you ahead.

01

Templates plateau.

The site you launched on Webflow or ClickFunnels did its job. Now it's the bottleneck — every new feature is a workaround, and the brand looks like every other operator using the same five sections.

02

Tools don't talk.

Stripe lives in Stripe. Whop lives in Whop. The CRM lives somewhere else. Someone on payroll spends their week being the human glue between systems that should be reconciling themselves.

03

Sites without backends are billboards.

Conversion is a function of measurement, and most off-the-shelf stacks don't measure what matters. Custom infrastructure is what turns a website into a revenue system.

Capabilities

Three things we ship. All custom. All yours.

01
Brand · interface · build

Design + custom sites

Sites that look like the brand you're building, not the SaaS template you started on. We design, we build, we deploy. Custom Next.js. Premium motion. Engineered for sub-one-second loads on mobile.

  • Brand and visual identity
  • Custom Next.js builds · no templates
  • Motion · 3D · interactive components
  • Sub-1s mobile load, SEO, accessibility
02
Database · integrations · attribution

Data infrastructure

Real database under your operations. Stripe and Whop reconciled hourly. Cohort tracking from day zero. Attribution from the first ad click to the paying customer. Dashboards that load instantly because the data is pre-aggregated.

  • Normalized Postgres — not spreadsheets
  • Webhook integration: Stripe, Whop, CRM, Calendly
  • Cohort retention, LTV by source, CAC payback
  • Observability and on-call alerting
03
Experiments · ML · always-on

Optimization retainer

Most of the value happens after launch. Monthly A/B testing with proper sample-size math. Lead scoring with calibrated probabilities. Refund and churn forecasting. The data-science layer most operators don't have because it requires real training.

  • Monthly A/B tests with FDR control + mSPRT
  • Lead scoring on every applicant · calibrated
  • Refund + churn forecasting models
  • Quarterly strategy reviews + roadmap
Selected work

Recent engagement. Measured outcomes.

01High-ticket service business · live
Engagement
Client confidential
Available on request

Custom funnel, qualification engine, and analytics infrastructure.

An operator running a high-ticket service business on a templated funnel was losing money in three places: a brand that looked like every competitor on the same builder, a one-question routing system sending every applicant to the same closer, and no measurement past the form submit. We replaced the funnel with a custom Next.js build, a five-step qualification engine with soft-disqualify routing, event-level analytics on every interaction, and a private dashboard for the operator. Demo-ready in under 48 hours.

fork() for GPUs — sub-second LLM session cloning.

Open-source Rust + CUDA library shipped by the studio. Snapshots LLM engine state to disk for sub-second cold restores — 17.2× faster cold starts (546s → 31.8s) on Llama-3-70B across two A100s. Pipelined DMA restore at 55 GB/s saturating PCIe Gen5. Production design partners running real workloads. vLLM and SGLang integrations across 9,400+ lines of Rust, Python, and PyO3.

Other engagements we take on
Custom site + Shopify integration

DTC brand site

Brand-led redesign with custom motion, product photography integration, and an analytics layer that finally connects ad spend to repeat purchase.

Reconciliation + private ops UI

Operations dashboard

Internal tooling that pulls Stripe, Whop, Discord, and Calendly into one source of truth. Reduces the manual relay work to zero.

Checkout + content + cohort tracking

Course platform

Replace Kajabi or Teachable with a custom platform. Real checkout, real content portal, real cohort retention analytics from day one.

Method

How we work. Audit, architect, ship, evolve.

01
Week 0 · Pre-engagement

Discover

A 90-minute audit of the current stack. We pull it apart — what works, what leaks, where money is being left on the table. You get a one-page report with specific dollar leaks, highest-leverage fixes, and a verdict on whether we're a fit. No commitment, no obligation.

02
Week 1 · Pre-build

Architect

Schema design, data flow, integration map, deployment plan. You see and approve every architectural decision before a line of code ships. By the end of week one you have a written spec of the system — not a black box you can't reason about.

03
Weeks 2–6 · Build

Ship

Custom site, backend, integrations, dashboards, analytics — delivered in chunks you can use as they land. Demo every Friday. Reconciliation in week one. Lead scoring by week four. Full handoff with documentation by week six.

04
Month 2+ · Retainer

Evolve

Monthly A/B tests. Quarterly model retraining. Ongoing integration of new tools as you adopt them. On-call when production breaks. You stop being the manual relay between systems. The infrastructure compounds.

Engagement

Three ways to engage. Project, retainer, or partnership.

Starter
$12K+ $2K / mo
3-month minimum · no kicker

A dip-your-toe engagement. Custom site, qualification quiz, baseline analytics, and one A/B test per quarter. No performance kicker, no advanced infrastructure — an honest minimum for operators who want to see the engineering before scaling the engagement.

Starter includes:
  • Custom Next.js build · no templates
  • Qualification quiz with branching logic
  • Baseline analytics + event tracking
  • One A/B test per quarter
  • Standard support · 48-hr response
Select starter
Studio·Most picked
$30K+ $6K / mo · 15% kicker
6-month minimum · 15% incremental kicker, 6 months

Everything in Starter, plus the full data infrastructure: normalized database, Stripe + Whop webhooks reconciled hourly, cohort tracking, attribution from first ad click to paying customer, lead scoring, and monthly A/B tests with real statistical methodology. The standard engagement.

Studio includes:
  • Everything in Starter
  • Normalized Postgres + integrations (Stripe, Whop, Discord, Calendly)
  • Cohort retention + LTV by source + CAC payback
  • Lead scoring · calibrated probabilities
  • Monthly A/B tests · sample-size, FDR, mSPRT

Select studio
Partnership
$50K+ $10K / mo · 20% kicker
12-month minimum · 20% incremental kicker, 6 months

Everything in Studio, plus we own the engineering function end-to-end. The Year-2 platform roadmap is included — your own branded platform replacing whatever rented stack you're on (Discord, Whop, Kajabi, etc.). For operators who want a real engineering seat, not a vendor.

Partnership includes:
  • Everything in Studio
  • End-to-end engineering ownership
  • Year-2 platform build included
  • ML & data-science layer (refund prediction, churn, LTV)
  • Quarterly strategic reviews + roadmap
  • Priority on-call · 4-hr SLA
Select partnership

All tiers include the free 90-minute discovery audit before commitment. Standard contract: 2-page MSA + SOW. Net-7 on build, monthly auto-pay on retainer. Performance kickers measured against a baseline captured in week one.

Studio

An independent practice. Small by design, not by default.

Matteson Systems is a boutique engineering studio working with small business operators who've outgrown off-the-shelf software. We design and build custom websites, data infrastructure, and the analytics layer behind them — and stay on as your engineering partner via monthly retainer.

Based in the San Francisco Bay Area. Currently booking one new engagement for Q3 2026 — by referral and inbound, not outbound.

01

Small surface, deep work.

We take on one to three engagements at a time. The math is intentional — fewer clients means real ownership and on-call that actually picks up.

02

Engineers, not vendors.

We design, build, deploy, and stay on. No handoffs to a separate dev shop. No design files that someone else has to translate.

03

Equity in the system.

Everything we ship is yours. Source code, schemas, docs, infrastructure. You own the system. We own the engagement.

Contact

Start a project. Or just say hi.

Send what you have — current site, ad spend, the tools you log into in a typical week. We'll send back a one-page audit with where money is leaking and what we'd build first. Free 90 minutes, no commitment.
