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.

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.

01

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.

02

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.

03

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.

Our Specialisation

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.

How we work

From Audit to Revenue Three Steps

Step 01

Free 60-min Audit

We look at your current setup — dev, ads, analytics, or all three. No sales pitch. We show you exactly where revenue is leaking and what the fix looks like. You leave with a clear picture regardless of what you decide next.

Step 02

Growth System Design

We scope the full growth system — which services you need, in what order, and what the KPIs look like at 30, 60, and 90 days. You approve the plan and numbers before a single hour of work begins.

Step 03

Build + Run Together

Dev ships fast. SEO goes live. Ads scale. CRO runs in parallel. One team, one Slack channel, one weekly dashboard. Revenue accountability from day one — not day ninety.

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.

James M.
eCommerce Founder, USA
Upwork — Verified Review

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.

Sarah R.
Agency Owner, UK
Clutch — Verified Review

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.
