Peak season is in14 weeks.

Checkout, loyalty, returns — shipped in days, not offshore sprints that miss the calendar.

Offshore handles bug fixes. Every experiment — cart, loyalty, returns portal — waits in a six-week queue while revenue walks. Tylt delivers production e-commerce features with senior review and product specs included. Shadow eval on your feature backlog before peak hits.

The DTC head of digital

Offshore maintains. Peak season needs shipping.

You can't vibe-code checkout. You can't wait six weeks for a returns portal. Revenue doesn't pause for sprint planning.

Features that move conversion — not just tickets closed

For brands where software is the storefront.

Peak-season velocity

Cart, checkout, loyalty — scoped and shipped in days before the calendar wins.

Production security

PCI-aware patterns, no exposed keys, senior review on every merge.

Stack-flexible

Shopify Plus, headless, custom — we build on what you run today.
The delivery model

From messy ask to production in days

No six-week discovery phase. No ticket queue. One continuous loop — spec, build, eval, ship — with senior people accountable at every step.

01

Your ask

A Slack message, a 30-minute call, a messy paragraph — however you actually communicate today.

02

Product spec

Our product lead returns scope, success metrics, and what we're not doing — same day.

03

Senior review

A named engineer signs off on approach, risks, and architecture before a line ships.

04

Build & eval

Agentic workers build at speed; seniors review every merge. Shadow eval on your data.

05

Production

Staging in days, pilot in weeks. Handoff docs, observability, 30-day fix window.

The formula

It takes all three.

A model supplies none of what makes great software. You bring the product expertise — what to build and how you'll know it's right. We bring the AI and engineering expertise, plus the agentic system that turns it into reviewed, production-grade code. Drop any one of the three and you get plausible code that doesn't fit, doesn't scale, or never ships.

You bring this

Product expertise

Your product expert

One person on your side owns what to build and how you'll know it's right — the requirements up front and the acceptance testing at the end. Nobody knows your business like you do.

It does what your business actually needs
Tylt brings this

AI + engineering expertise

An AI-native senior engineer

One of our top engineers — fluent in both the model and the architecture — owns the quality bar, reviews everything the agents produce, and rejects what only looks right.

It works as expected and scales to your daily active users
Tylt brings this

The system we built

Our agentic worker system

A purpose-built harness puts a configurable fleet of agent workers to work under that engineer's direction, doing the physical build at speed. Dial it up or down to match your pace.

  • Coding
  • Specs
  • Documentation
  • Testing
  • Deployment
It ships fast, without the headcount or the bill

= a great product

Software that does exactly what it's supposed to do — and scales to the daily active users you need it to.

Three options

Offshore vs agency vs Tylt

Offshore is cheap until you count your time. US agencies are quality until you see the invoice. Tylt is the third option — onshore accountability at offshore economics.
