We build the engine
and the fuel. The system that
drives your revenue.
Full-stack engineering meets performance marketing. One team across dev, SEO, and paid acquisition — built to scale your revenue as a system. For scaling businesses in the USA, UK, Europe and Australia.
What we build
One team.
Dev + SEO + Paid Ads & CRO.
Most agencies do one thing. We build the product AND run the growth system — simultaneously. No handoff gaps. No finger-pointing. One set of KPIs.
Shopify Development
Custom Shopify stores, headless builds, theme development and app integrations. Built to convert for US, UK, and Australian eCommerce brands — not just to look good.
Google Ads Management
Search, Shopping, and PMax campaigns managed for revenue — not just clicks or impressions. ROAS-first, always. For businesses spending $5K–$100K per month.
Meta Ads
Full-funnel Meta campaigns from cold prospecting to retargeting to purchase. ROAS-focused, not reach-focused. eCommerce, coaches, and SaaS brands that want results.
Web Development
Next.js, React, and WordPress — fast, SEO-ready, and conversion-optimised for Western markets. Core Web Vitals built in from day one.
Mobile Apps
React Native for iOS and Android. From MVP concept to production-ready in weeks, not months. For funded startups and growing businesses that need to ship fast.
CRO and Analytics
GA4, heatmaps, and A/B testing. Turn your existing traffic into significantly more revenue without increasing your ad spend. Data-led, outcome-accountable.
SEO Services
Technical SEO, Shopify SEO, content strategy and link building — all revenue-focused. We don't just drive traffic, we drive traffic that converts.
White Label
Silent partner development for US and UK agencies. White-label Shopify, web, mobile and SEO delivery under your brand — your client never knows we exist.
eCommerce Growth
Dev, ads, SEO and CRO working simultaneously under one roof — the only agency managing all four together. Most businesses use four separate vendors with four separate KPIs and no one accountable for revenue. We fix that. One team. One goal.
Who we help
Three types of clients.
One common problem.
Fragmented vendors. No revenue accountability. Agencies that report activity instead of results. We fix that — for good.
Startup Founders
Can't afford UK or US agency rates. Worried about offshore communication gaps and missed deadlines. Need to ship fast and look credible in Western markets from day one.
We speak your language, ship at your speed, and cost a fraction of a Western agency.
eCommerce Operators
One agency for dev. Another for ads. No one accountable for actual revenue. The left hand never talks to the right. ROAS is someone else's problem — until it's yours.
Dev + SEO + Ads & CRO. One team. One set of KPIs. One number that matters: your increasing ROAS and decreasing COST.
Agency Partners
Your clients need dev or paid ads execution. Your team is at capacity. You can't miss a deadline, lose a client, or lower your margins hiring in-house right now.
We deliver under your brand. You invoice. Your client never knows we're involved.
Proof of work
Numbers that
actually matter.
10+ years delivering for clients across the USA, UK, EU, and Australia. Real dashboards. Real numbers. Available on request before any engagement.
$300K+ revenue. 60 days.
One growth system.
A US-based eCommerce brand came to us with fragmented vendors and a 1.8x ROAS. We rebuilt their Shopify store, restructured their Meta Ads funnel, and ran a CRO programme in parallel. The numbers speak for themselves.
We specialise in eCommerce.
Exclusively.
Shopify stores, DTC brands and online retailers are our primary clients. We build stores that load fast and convert. We run the ads that drive profitable traffic. We do the SEO that compounds. We optimise the conversion rate on every page. Not one of these. All four. Simultaneously.
The BillionX edge
Full-stack. Full-funnel.
Full accountability.
Ship 3x faster
AI-augmented development with Claude Code and Vibe Coding. We deliver in days, not weeks. Screen recordings of every project are available on request — you see the work, not just the invoice.
Dev + Ads together
We're the rare team that speaks both engineering and revenue. Build the product AND run the growth system at the same time. No handoff gaps, no vendor blame, one set of revenue KPIs.
High-altitude thinking
Operating from Mandi, Himachal Pradesh — zero overhead, 100% focus on your output. You get senior-level execution at a fraction of Western agency rates, founder-led on every engagement.
How we work
From audit to revenue.
Three steps.
Client feedback
What clients say about
working with us.
“Dushyant's team rebuilt our Shopify store and managed our Meta Ads simultaneously. ROAS went from 1.8x to over 4x in under 60 days. I've never worked with a team where dev and ads communicate this tightly.”
“We brought BillionX in as our white-label dev partner. They shipped a Next.js build in 12 days. Our client thought we built it in-house. The speed and quality were both exceptional — exactly what we needed.”
“Straight communication, real dashboards, and results I can show my board. No offshore horror stories — this is a founder who cares about the outcome, not just the billable hours.”
