E-Commerce Development
in Los Angeles

Storefronts that convert and checkouts that don't break at scale.

We build e-commerce storefronts for founders in Los Angeles — headless Shopify Hydrogen when you need custom UX, a hardened Shopify Plus theme when speed matters more, custom carts when the platform gets in the way. One senior engineer owns checkout, inventory sync, and the storefront, so launch day isn't held together by three unrelated apps.

One AI-native engineer.
The output of a team.

One senior engineer plus AI agents now ships e-commerce development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in Los Angeles who need to ship before the next round closes.

The local read

Why e-commerce development is hard in Los Angeles

LA's funded-startup count is larger than Tel Aviv's and Austin's combined, but the engineer-per-startup ratio is the worst on the West Coast. 70+ day hiring cycles. Local agencies are mostly creative-tech shops — great at brand work, slow at shipping infrastructure.

We do the infrastructure. One senior engineer owns your build, Pacific Time, overlap with both your in-house team and your East Coast investors. ComfyUI, Replicate, Runway for media-tech. Next.js + Postgres for everything else. Flat-price quote in 24 hours. Code yours from commit one.

Hiring one senior engineer here is a ~$310K year-one outlay and a 60–90 day search. Our e-commerce development engagement starts at $3,000 with a first deploy in 2–3 weeks.

“When we started, there was no website, no technical foundation, just an idea and a clear vision of what I wanted to build. Valery and the Start Matter team took that vision seriously and helped me turn it into a real product from scratch. What I appreciated most was how easy and human the collaboration felt. They listened carefully, explained things in a way I could understand, and genuinely cared about building something that would work long-term, not just "finish a task." I always felt supported and involved in the process. Start Matter handled everything end to end and made the whole journey smooth and stress-free. Today, Sweet and Savory Meals is live, growing, and built on a solid foundation I trust. I’m truly grateful for their work, their patience, and their commitment, and I would happily recommend Start Matter to anyone looking for a reliable and thoughtful development partner.”

FAQ

Common questions about e-commerce development
in Los Angeles

How fast can you start?

Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Headless Hydrogen or a Shopify Plus theme?

Theme-based if you need to launch in two weeks and the design is close to what Shopify templates support well. Headless Hydrogen if you need custom UX, sub-second page loads, or you're integrating commerce into a larger product rather than shipping a standalone storefront.

Do you migrate from another platform?

Yes — most commonly from WooCommerce or a custom cart to Shopify. Product catalog, customer accounts, and order history migrate; we flag anything that won't map cleanly before we start.

Who owns the code?

You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
