Bhushan.

Builder-Scaler in product and growth analytics. I design and scale data systems that turn ambiguity into measurable growth.

A bit about me.

Vyom Bhushan
I'm Vyom. I've been the sole data hire at a startup that scaled to 1M users, caught fraud that was quietly bleeding $100K/month, shipped a SaaS product to $2M ARR at a global consulting firm, and built scoring models that changed how an entire sales org prioritises outreach.

I work across the data full stack: experimentation, propensity models, analytics engineering, AI workflows. I'm most useful when things are ambiguous, the data is messy, and someone needs to figure out what to measure and why it matters.

Work I'm Proud Of

Event Tracking & Onboarding Diagnostics

The Problem
With 1M+ users onboarding, there was no structured event tracking - zero visibility into where users were dropping off or why.
What I Built
Deployed a Segment-style event tracking architecture using mParticle, funneling behavioural data into BigQuery. This became the foundation for funnel analysis, cohort retention, and feature adoption tracking across the org.
The Incident
The funnel revealed a 50% drop-off at the onboarding page itself - far above expected. I built a step-by-step customer funnel to diagnose. Turned out half the users weren't receiving their OTPs for sign-up. The issue was on the SMS provider's end. Got it escalated and fixed - onboarding completion recovered immediately.
Event tracking became the backbone of all product decisions. The OTP fix alone recovered ~50% of lost sign-ups overnight.

Fraud Analysis - Rewards Engine Exploit

The Problem
Reward burn was running at 7–8x forecast. Unit economics weren't making sense at the cohort level. There was no fraud team, no monitoring, no alerts.
What I Found
~7% of users were driving 55% of total reward burn through two mechanisms - duplicate accounts exploiting referral bonuses, and transaction reversals made after rewards had already been earned. This was quietly bleeding the business model.
The Hard Part
Overcorrecting risked adding friction for legitimate users and slowing growth. Undercorrecting meant letting an incentive design flaw compound. That tension shaped every stakeholder conversation.
What I Built
Analysis in BigQuery using mParticle event data cross-referenced in Looker. Detection: device fingerprinting, behavioural clustering for duplicates, reversal-to-reward timestamp mapping. Designed a rules-based flagging system (device ID matching, reversal frequency thresholds, redemption velocity triggers). Redesigned onboarding to block duplicates. Set up automated Slack alerts and a Metabase dashboard for ops.
~$100K/month saved in reward burn. No noticeable retention impact. Gave leadership confidence in unit economics ahead of Series A.

0-to-1 SaaS Product: Budget Planner

The Problem
Pharma commercial teams were planning marketing budgets in spreadsheets. No way to model channel-level ROI, no scenario simulation, no shared view across brands. ZS had deep consulting expertise in marketing mix but no self-serve product clients could use independently.
What I Did
I was the cross-functional glue between product, engineering and design on a team of 30. Defined the success metrics, designed the analytical models underpinning budget optimization, and owned the product roadmap. Spent most of my time translating what Fortune 500 pharma stakeholders needed into specs engineers could build against.
The Tradeoff
Building for pharma means navigating compliance, slow procurement cycles and stakeholders who think in PowerPoint, not product. The constant tension was between shipping fast to prove SaaS viability for ZS and building robust enough to survive enterprise scrutiny. We chose to ship narrow and deep rather than broad and shallow.
$2M ARR in Year 1. Budget Planner is now a live product in the ZAIDYN Marketplace, used across 65+ countries.

Customer Scoring Framework

The Problem
Growth and Sales teams were prioritising RM outreach manually with no consistent ranking. A lot of time was being spent trying to convert low-value customers. No one agreed on what a valuable customer looked like or when to reach out.
What I Built
Designed a composite scoring model combining opportunity signals (balance growth, wallet share, transaction volume, card activity, savings) with timing and engagement signals (call connect rates, email engagement, recency, primary account behaviour). Each component was individually scored and exposed, not black-boxed.
Data Quality
Built end-to-end quality checks, reconciliation logic across sources (HubSpot, CASS, balances), and guardrails to prevent silent row drops. Ensured every dashboard output was defensible to senior stakeholders.
The Tradeoff
A simpler score would have shipped faster but wouldn't have earned trust. RMs needed to understand why a customer ranked high, not just that they did. Exposing each component individually meant more complexity to build, but it gave stakeholders a score they could interrogate and believe in.
Gave RMs a single trusted ranking. Replaced broad manual targeting with data-driven prioritisation. Outreach success improved by 45%.

The Reality of Text-to-SQL at Scale: Cost, Latency, and What Actually Works

Event Analytics in the Age of Agents

How Emisar used agent-led analytics to move from manual event inspection to journey summaries, targeted QC, and faster product judgment.

Pieces Of Me

A glimpse into the shades that define who I am

The Data Detective

Fraud nobody was looking for, OTP failures hiding in plain sight, pipelines silently dropping rows. I find what's broken before it becomes a crisis.

The Experimenter

From A/B tests to life decisions, I believe in letting data guide the way. Bayesian at heart, curious by nature.

The Builder

Whether it's a 0-to-1 product or an analytics stack from scratch, I thrive on creating something from nothing.

The Storyteller

Numbers don't move people, narratives do. I turn data into the kind of story that gets executives to act, whether it's sizing fraud in dollars or making a score stakeholders trust.

Let's Connect.

Always up for a conversation about data, AI, or the next big thing.
