Propeller is a Shopify agency that owns the entire commerce system end-to-end. We handle storefront design, Shopify and Shopify Plus development, migrations (Webflow, Squarespace, BigCommerce, WooCommerce), conversion rate optimization, SEO, paid media, Klaviyo retention, and custom integrations. One team. Integrated accountability. Compounding results.
What's broken
- Stop wasting time and money on agency theater. Most Shopify shops deliver a launch and disappear. You own the optimization risk, the Black Friday failures, the technical debt.
- Your current setup separated design from development from growth. Nothing compounds. Checkout breaks? Marketing campaign underperforms? Each vendor points at the other. You're the glue managing three teams.
- You're paying multiple agencies to avoid talking to each other. You're managing the relationship, missing revenue compounds, and nothing gets optimized because nobody owns the outcome.
How we fix it
Propeller is built around integrated ownership. The designer who builds your checkout is the same person running conversion tests post-launch. The developer stays on to measure what actually moved revenue. We don't ship and vanish.
We deliver ROI-driven Shopify strategy that moves people from consideration to repeat customers. We consistently deliver 2-3x revenue growth for our clients within 12 months of launch. We measure success one way: revenue, compounded over time.
How would you like your inbox to be flooded with orders like this?
A working Shopify system does not send slideware. It sends orders - compounding, every day. This is what that looks like before it hits the dashboard.

Diagnose. Ship. Compound.
Align
We clarify the Shopify goal, constraints, and what success looks like in revenue - not vanity metrics.
Diagnose
We audit the experience, stack, and growth system against what ambitious brands actually need.
Build
Senior team ships the work: storefront, flows, campaigns, or technology - without agency theater.
Prove
We measure what moved, then compound. Commerce is a system, not a launch party.

When you search for a Shopify agency in Los Angeles or a Shopify Plus partner that handles design, development, and growth under one roof, you're looking for integrated accountability. Propeller is built exactly that way. We work with brands doing $2M to $100M+ annually across ecommerce categories (spirits, beauty, luxury, CPG, hospitality) and all platform migrations (from Webflow, Squarespace, BigCommerce, WooCommerce, or custom builds to Shopify).
In 2026, Shopify is table stakes. But what matters is how you build, optimize, and scale on Shopify. We specialize in category-leading performance: new Shopify and Shopify Plus builds, zero-loss migrations, redesigns that drive conversion lifts, Hydrogen custom storefronts for personalized commerce, and ongoing growth retainers that keep compounding what works.
Our Santa Monica studio is 15 people. We keep core work in-house. No offshore bait-and-switch. No ticket queue retainers. No 'we ship it and you hire a CRO agency.' We stay on. Growth accrues. Revenue compounds.

Objections
- Are you just another Shopify theme shop?
- No. Theme shops assemble stores and disappear. We build custom storefronts on Shopify's architecture, stay on post-launch, and measure revenue. We own the outcome. Our clients see 2-3x revenue growth because the team that discovers the problem builds and optimizes the solution.
- Do you work with established brands or early-stage?
- Our sweet spot is ambitious brands with real revenue ($2M+) who care about performance over price. We've migrated stores from Webflow, Squarespace, BigCommerce, and WooCommerce - and built Shopify Plus systems for enterprise. The common thread: clients who want accountability, not vanity metrics.
- Can you migrate to Shopify without losing SEO or sales?
- Yes. We handle URL mapping, redirect hierarchies, metadata preservation, and analytics coordination so organic equity transfers intact. Most clients see SEO improve during migration because Shopify's infrastructure loads faster. We document every step so you're never in the dark.
- What's the cost and timeline?
- Shopify builds: $100-150K for standard, $250-500K+ for Plus. Migrations: $75-200K depending on complexity. Timelines: 4-6 months for standard Shopify, 6-9 for Plus. We scope every project uniquely based on what your revenue actually needs.
- What makes Propeller different?
- We own design, development, and growth. No handoffs. No offshore bait-and-switch. No 'we ship it and you hire a CRO agency.' The team that builds your store stays on to compound results. That integrated accountability is rare.
FAQ
What does a Shopify agency do that I can't hire piecemeal?
You could hire a designer, developer, and growth person separately. But who owns the result? Who's accountable when checkout broken on mobile? Who optimizes based on real data? Propeller is accountable for the entire commerce system working together. That integration matters.
How much does a Shopify build cost?
Shopify builds range $75K to $300K+ depending on complexity. New basic Shopify build: $100-150K. Shopify Plus implementation: $250-500K+. Hydrogen custom storefronts: $200-400K+. We scope every project uniquely.
How long does a Shopify project take?
Standard Shopify: 4-6 months (discovery to launch). Shopify Plus: 6-9 months. Hydrogen: 6-12 months. We prioritize quality over speed. Fast deliveries usually mean cut corners.
Can you handle Shopify Plus and complex integrations?
Yes. Shopify Plus architecture, checkout extensibility, Functions, B2B, multi-market setup, ERP/OMS connections, and custom apps are our core work.
What's the difference between Shopify and Shopify Plus?
Shopify is for brands up to high-volume. Shopify Plus adds checkout customization, Functions (composable architecture), wholesale features, and advanced multi-market for $2K+ monthly. Plus makes sense at $5M+ revenue or high complexity.
Do you offer Hydrogen development?
Yes. Hydrogen is Shopify's headless commerce framework for custom, high-performance storefronts. We build Hydrogen for brands needing personalization, custom experiences, or extreme customization that Online Store 2.0 can't deliver.
Can you migrate our store from Webflow/Squarespace/BigCommerce to Shopify?
Yes. We've migrated dozens of stores with zero SEO loss. We handle URL mapping, 301 redirects, metadata preservation, analytics connection, and data transfer. Most clients report SEO improvement because Shopify loads faster.
What's included in post-launch support?
Our Commerce Partner retainers include: ongoing storefront optimization, CRO testing and implementation, Klaviyo and growth strategy, SEO updates, and technology maintenance. Same team that built it keeps compounding results.
How do you measure success?
Revenue. We track organic traffic, paid media ROI, conversion rate, average order value, repeat purchase rate, and customer acquisition cost. Every month. For years.
