About Conversion

The full-funnel growth engine behind our own name

  • San Francisco, USA

    In-house team

  • Pay-on-Results

    Fee moves with revenue

Conversion is a growth marketing agency headquartered in San Francisco, founded by Tarun Kapoor and a Shopify Plus Partner. We built our own name and tagline, Growth Partners In Your Entrepreneurial Journey, around a single idea: acquisition, retention, and conversion optimization work better as one system than as five disconnected vendors billing separately. One in-house team of media buyers, lifecycle marketers, CRO analysts, and a senior growth lead runs Meta and Instagram ads, email and SMS retention, and conversion rate optimization for Shopify stores against a single revenue number.

This is the umbrella entry point for brands who know they need to grow but aren't sure which channel to start with. If you already know the one workstream you need, a focused engagement such as our SEO agency service may fit better on its own, and brands built on Shopify or Shopify Plus can get the same full-funnel discipline through our Shopify marketing agency. Either way, reporting ties back to revenue and contribution margin, starting from a baseline like the one in our break-even ROAS guide.

Why growth stalls

Five vendors, zero accountability

Most brands don't have a growth problem. They have a coordination problem. The same three patterns show up whenever we take over from a stack of disconnected vendors.

  • Channel silos with no shared scoreboard

    Your paid agency reports ROAS, your email vendor reports open rates, your CRO freelancer reports test wins, and none of it reconciles to a single revenue number. When growth stalls, everyone points at everyone else's dashboard. We run one attribution model and one scorecard across every channel, so there's nowhere to hide.

  • Retainers regardless of results

    Large agencies bill the same flat retainer whether your revenue grows 40% or 4%. There's no financial incentive to reallocate budget toward what's working. Pay-on-results is our default model, not an upsell. Our fee moves with your revenue, so reallocating toward what compounds is in our own interest too.

  • Senior team in the pitch, junior team on the account

    You buy the founder and the strategy deck in the sales meeting, then get handed off to a rotating account coordinator who relays requests to an offshore execution team. Every Conversion account keeps a senior growth lead embedded for the life of the engagement. The person who built the strategy is the person running the weekly call.

What's inside the engagement

Growth marketing services, run by one team

Full-funnel growth marketing means every workstream below is coordinated against one revenue target and one shared attribution model. The artifacts each one produces are yours to keep, edit, and own.

  • Paid Social on Meta and TikTok

    Full-funnel media buying on Meta and TikTok by one media team working off a shared budget model, with account build or audit included. Emerging channels such as Pinterest and Reddit get a written test plan and a test budget.

  • Google Search, Shopping and Performance Max

    Google Ads account build or audit across Search, Shopping, and Performance Max, with YouTube tested alongside. Budget is allocated across all paid channels from one model, so channels are not bidding against each other for the same customer.

  • Creative Testing at Scale

    AI-assisted UGC and avatar-based ad variants on a weekly testing cadence per channel. You get a creative testing matrix covering hooks, angles, and formats, an ad variant library, and winning creative fed back into organic and lifecycle.

  • Retention & Lifecycle Marketing

    Email and SMS built in Klaviyo to turn one-time buyers into repeat revenue. Full flow build-out (welcome, post-purchase, win-back, VIP), SMS strategy and compliance, segmentation by purchase behavior and predicted LTV, and a campaign calendar tied to the product and promotional calendar.

  • Conversion Rate Optimization & Experimentation

    A/B testing across landing pages, PDPs, and cart so every visitor converts at a higher rate. Statistically rigorous test design with no calling tests early, and an A/B testing roadmap prioritized by revenue impact.

  • Landing Pages, PDP and Checkout

    Landing page templates for paid traffic, a PDP and checkout optimization plan, and heatmap, session replay, and form analytics setup so test ideas come from observed behavior.

  • Analytics, Attribution & Reporting

    GA4 and server-side event tracking, a blended MER model, and incrementality testing, so you know what's driving revenue beyond what each platform's dashboard claims. Includes a weekly revenue-tied dashboard, a contribution margin scorecard by channel and campaign, and attribution documentation and runbooks.

  • Growth Strategy & Quarterly Roadmap

    A full-funnel growth audit deck, a competitive teardown, a revenue and contribution margin baseline, and a single quarterly roadmap across acquisition, retention, and conversion. Includes the channel budget allocation model, board-ready reporting, and one senior growth lead accountable for the whole number.

How the engagement runs

From audit to compounding growth in four stages

  1. Step 01

    Growth audit & baseline

    A full review of current acquisition, retention, and CRO performance, plus an analytics and attribution accuracy check. Output: an audit deck and a revenue/contribution-margin baseline scorecard we both agree on.

  2. Step 02

    Strategy & roadmap

    A priority-ranked quarterly roadmap across paid, retention, and conversion, tied to a specific revenue or margin target and signed off before a dollar moves.

  3. Step 03

    Build & launch

    Accounts built or audited, tracking implemented, creative pipeline stood up, retention flows built, and the first round of tests go live across every channel in scope.

  4. Step 04

    Scale & optimize

    A weekly test cycle with budget reallocated toward whatever is compounding, and reporting tied to revenue and contribution margin instead of platform vanity metrics.

Frequently asked

Growth marketing agency questions

What does a growth marketing agency do?
A growth marketing agency runs the full customer acquisition and retention funnel as one connected system: paid media across Meta, Google, and TikTok, retention marketing via email and SMS, conversion rate optimization on your site, and the analytics layer that tells you what's driving revenue. Instead of hiring a PPC shop, an email freelancer, a CRO consultant, and an SEO agency separately, you get one team accountable for the whole revenue number, testing and reallocating budget across channels based on what's compounding.
How much does a growth marketing agency cost?
Engagements typically combine a base fee tied to ad spend and channel scope, usually $5,000 to $25,000/month for brands spending $50K to $500K/month on paid media, plus a performance component tied to incremental revenue or contribution margin growth above an agreed baseline. Brands that want a pure pay-on-results structure pay 10 to 20% of incremental revenue with no fee if growth targets aren't hit. We quote a fixed structure after a 30-minute discovery call, with no generic rate card.
How does the pay-on-results model actually work?
We set a measurable baseline during the audit phase: revenue, contribution margin, or a blended metric you approve. From there, fees scale with performance above that baseline. Some engagements are 100% pay-on-results; others use a smaller base fee (to cover ad spend management and tooling) plus a performance kicker. Either way, we only make more when your P&L does.
What's the typical timeline to see meaningful growth?
Leading indicators such as CTR, landing page conversion rate, email/SMS revenue share, and test velocity usually move within the first 30 days as tracking gets fixed and the first experiments go live. Compounding revenue growth typically shows up in the 90 to 120 day window once retention flows mature and winning paid creative gets scaled. Full-funnel maturity, where every channel is optimized against a shared attribution model, is a 2 to 3 quarter build.
What is growth marketing, and how is it different from traditional marketing?
Traditional marketing optimizes for brand awareness and campaign output: impressions, reach, a finished creative asset. Growth marketing optimizes for a single number: revenue (or contribution margin) per dollar and hour invested. That means constant experimentation, a shared analytics layer across every channel, and budget that moves toward whatever is compounding.
What size brand is a good fit for a growth marketing agency?
Most of our full-funnel engagements start with brands doing $500K to $20M in annual revenue that already have product-market fit but are running acquisition, retention, and CRO as disconnected workstreams. If you're pre-revenue or still validating product-market fit, a lighter, single-channel engagement is usually the better starting point, and we'll tell you that directly on the first call.
How many channels should we run at once?
Most brands are better served running 2 to 3 paid channels deeply (usually Meta plus Google, with TikTok or an emerging channel as a test budget) alongside retention and CRO. Spreading across five channels leaves no channel with enough spend to reach statistical significance. We build the channel mix around your AOV, margin, and existing customer data.
How is this different from hiring an SEO agency or a PPC agency directly?
If you already know the one channel you need, such as organic search, or paid search and CRO specifically, a channel specialist is the right, more focused hire. Our SEO Agency and CRO services exist for exactly that. Growth Marketing Agency is the umbrella engagement: one team running paid, retention, conversion, and analytics together, with a shared budget and reporting model, for brands who don't want to manage four vendors and reconcile four sets of numbers themselves.
Do you work with healthcare brands, or only Shopify and ecommerce?
Both. We run full-funnel growth for Shopify and DTC ecommerce brands as well as healthcare and direct-to-patient brands, where compliance (HIPAA-adjacent data handling, platform ad policy restrictions, claims language) adds a layer most generalist growth agencies aren't built to handle. You don't need to be on Shopify: the engagement works the same way on BigCommerce, WooCommerce, headless storefronts, or a healthcare intake funnel that isn't ecommerce at all.
What tools and platforms do you use?
Meta Ads Manager, Google Ads (Search, Shopping, Performance Max), TikTok Ads, Klaviyo for email/SMS, GA4 with server-side tagging, and a blended MER/incrementality model for attribution. On the CRO side we run tests through standard experimentation platforms with heatmaps and session replay layered in. We integrate with whatever CDP, ERP, or subscription platform (Recharge, Skio) you're already running, with no forced migration.
Can you work alongside our existing in-house marketing team, or do you replace it?
Most of our full-funnel engagements run alongside an in-house team. We typically take ownership of paid media, retention build-out, and CRO experimentation while your team owns brand, product marketing, and day-to-day customer relationships. We report into whoever owns the revenue number on your side, with a single dashboard and a weekly call covering revenue, contribution margin, blended MER, and channel-by-channel performance against the quarterly roadmap.
