We design, build, and maintain the analytics, websites, and automation your business runs on — engineered and verified, not improvised.
Helping revenue businesses trust their numbers again.

Our lab
trackinglab.shop is our live laboratory: server-side tagging, webhook-verified orders, and a BigQuery warehouse — every technique we sell, deployed and monitored on ourselves before it touches a client.

breakage alert latency
Marketing platforms grade their own homework. Tracking breaks silently. And the cost compounds with every budget decision.
Numbers that don't match
Your ad platform, analytics, and bank statement each tell a different story. Decisions made on conflicting data are guesses with extra steps.
Invisible revenue leaks
Blocked scripts, duplicate events, and broken checkout tracking silently distort attribution — and your budget follows the distortion.
Manual everything
Reports assembled by hand, orders reconciled in spreadsheets, alerts that arrive after the damage. Operations that don't scale past you.
We deliver complete measurement, web, and automation engineering under one roof.
Four gates. Every engagement passes through all of them — nothing ships on assumption.
- 01
Audit
A fixed-fee diagnostic of your measurement, site, and data flows. Automated scans plus manual engineering review.
- 02
Blueprint
A precise scope with fixed pricing. Deliverables, timeline, and cost — agreed in writing before work begins.
- 03
Build
We implement and verify every event against real traffic, end to end, before handover.
- 04
Monitor
Uptime checks on your tracking, monthly data-quality QA, and alerting that catches breakage before your reports do.
BUILT LIKEinfrastructure,BECAUSE IT IS.
Your measurement and website aren't marketing assets — they're operational infrastructure. We treat them with the same rigor as production software.
- Every implementation is verified against real traffic before handover — not assumed to work.
- Independent measurement: we don't buy your media, so our numbers have no incentive to flatter.
- Fixed-fee packages with defined deliverables — you never fund an open-ended timesheet.
- Privacy-first architecture: consent-aware, first-party, and compliant by design.
- Automated monitoring keeps watch after launch, so breakage is caught in hours, not quarters.
From the founder
“I started Vextren after watching businesses make six-figure decisions on numbers nobody had verified. We build the version of your data you can bet on — because we bet on it first, with our own store.”
Tushar Jankhyan
Founder & Lead Engineer
A fixed-fee engineering review of your measurement and site. One week, a written report, and a walkthrough call. Keep the findings either way.
