In-house team

Conversion is a growth marketing agency headquartered in San Francisco, founded in 2018 by Tarun Kapoor and a Shopify Plus Partner since 2019. 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.

This is the umbrella entry point for brands who know they need to grow but aren't sure which specific channel to start with. Instead of hiring a paid media shop, an email freelancer, a CRO consultant, and an analytics contractor and hoping they coordinate, you get one in-house team — media buyers, lifecycle marketers, CRO analysts, and a senior growth lead — accountable for a single revenue number.

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 actually 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

Every growth lever, run by one team

Full-funnel growth marketing means every workstream below is coordinated against one revenue target and one shared attribution model — not bought separately from five vendors.

Paid Acquisition Across Every Channel That Matters

Meta, Google (Search, Shopping, Performance Max), TikTok, and emerging channels like Pinterest and Reddit — managed by one media team working off a shared budget model, not competing agencies bidding against each other for the same customer.

  • Meta + TikTok + Google full-funnel media buying
  • Emerging channel testing: Pinterest, Reddit, YouTube
  • Creative-led testing cadence, not just bid management
  • Shared budget allocation model across all paid channels

Retention & Lifecycle Marketing

Email and SMS built in Klaviyo to turn one-time buyers into repeat revenue. Flows, segmentation, and campaign calendars engineered against LTV and contribution margin, not open rates.

  • Full Klaviyo flow build-out (welcome, post-purchase, win-back, VIP)
  • SMS strategy and compliance
  • Segmentation by purchase behavior and predicted LTV
  • Campaign calendar tied to the product and promotional calendar

Conversion Rate Optimization & Experimentation

A/B testing across landing pages, PDPs, and checkout so every visitor paid and organic acquisition brings in converts at a higher rate. Statistically rigorous experiments, not opinion-led redesigns.

  • Landing page, PDP, and cart A/B testing
  • Heatmaps, session replay, and form analytics
  • Statistically rigorous test design — no calling tests early
  • CRO roadmap prioritized by revenue impact

Analytics, Attribution & Reporting

GA4, server-side tracking, and a blended MER model so you know what's actually driving revenue — not just what each platform's dashboard claims credit for.

  • GA4 and server-side event tracking setup
  • Blended MER and incrementality testing
  • Weekly revenue-tied reporting dashboard
  • Contribution margin visibility by channel and campaign

Creative Testing at Scale

AI-assisted UGC and ad variant production so the media team never runs out of fresh creative to test — the single biggest lever on paid performance once accounts are optimized.

  • AI-assisted UGC and avatar-based ad variants
  • Weekly creative testing cadence per channel
  • Hook, angle, and format testing matrices
  • Winning creative fed back into organic and lifecycle

Growth Strategy & Quarterly Roadmap Planning

A single quarterly roadmap across acquisition, retention, and conversion — prioritized by revenue impact, not by which channel team is loudest in the planning meeting.

  • Quarterly growth roadmap and prioritization model
  • Cross-channel budget allocation
  • Board-ready reporting on revenue and contribution margin
  • One senior growth lead accountable for the whole number

How the engagement runs

From audit to compounding growth in four stages

Conversion's four-stage growth process visualized in brand blue and green

04

Growth marketing case studies

Real funnels. Real revenue.

DTC — Skincare

+156%

Revenue growth in 6 months

A stalled skincare brand went from flat to compounding month-over-month growth

B2B — Industrial Supplier

+3.1×

Marketing-sourced pipeline

An industrial supplier tripled marketing-sourced pipeline with one accountable team

“Our old setup had a PPC shop and an in-house marketer who never talked to each other. Conversion rebuilt our funnel end to end and pipeline tripled within two quarters.”

Healthcare — Direct-to-Patient

−41%

Cost per acquired patient

A direct-to-patient healthcare brand cut acquisition cost while scaling spend 2×

“Healthcare marketing has compliance landmines most agencies don't understand. Conversion scaled our paid and retention together without a single compliance flag, and our CAC actually dropped as we scaled.”

What founders say

Trusted by brands who were done juggling vendors

Every other agency wanted a flat retainer before proving anything. Conversion proposed a pay-on-results structure and hit the baseline in the first quarter. That's the only pitch that made sense to us.

Emma S.

Founder · DTC Skincare Brand

We had a PPC vendor, an internal email person, and nobody looking at the whole funnel. Conversion put one team and one scoreboard on it, and for the first time everyone was optimizing toward the same number.

Raj P.

VP Marketing · B2B Industrial Supplier

The senior growth lead who scoped our engagement is the same person running our weekly call eight months later. No rotating account manager, no re-explaining our business every quarter.

Chloe M.

Director of Growth · Health & Wellness Brand

Our weekly report is one page: revenue, contribution margin, and what moved it. No platform screenshots, no vanity metrics. It's the first reporting I've ever actually read end to end.

Victor A.

CMO · DTC Apparel Brand

I was managing four separate invoices and four separate strategies before this. Now it's one team, one budget, and one number I actually track against our board deck.

Priya D.

Founder & CEO · Beauty Subscription Brand

Healthcare compliance killed our last two agency relationships — they either moved too slow or got our ad accounts flagged. Conversion built compliance into the process from day one and still scaled spend.

Marcus L.

Head of Growth · Direct-to-Patient Healthcare Brand

Why Conversion

We're not a media buyer. We're the whole growth team.

Pay on results, not just promises

Pay-on-results is our default engagement model, not an upsell tacked onto a retainer. Our fee moves with the revenue and contribution margin we produce, so reallocating budget toward what's working is in our interest too.

One team, one revenue number

Paid, retention, CRO, and analytics report through a single growth lead against a single scorecard. When something underperforms, there's one team to ask — not five vendors blaming each other's channel.

Senior growth leads, not account managers

The person who scopes your strategy is the person running your weekly call for the life of the engagement. No rotating account-management layer standing between you and the people doing the work.

Weekly reporting tied to revenue and margin

Every report ties back to revenue or contribution margin — not reach, impressions, or open rate. If a metric doesn't move the P&L, it doesn't make the weekly call.

Full-funnel by default

Acquisition, retention, conversion, and analytics are built as one system from day one, with a shared attribution model — not bolted together after separately hiring four specialists.

In-house, US-based, since 2018

Founded in San Francisco in 2018 and a Shopify Plus Partner since 2019. Our media buyers, lifecycle marketers, CRO analysts, and engineers work in-house — no subcontracted execution layer.

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 actually 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–$25,000/month for brands spending $50K–$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 10–20% of incremental revenue with no fee if growth targets aren't hit. We quote a fixed structure after a 30-minute discovery call, not a generic rate card.
How does the pay-on-results model actually work?
We set a measurable baseline — revenue, contribution margin, or a blended metric you approve — during the audit phase. From there, fees scale with performance above that baseline instead of a flat retainer you pay whether or not results show up. 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, the incentive structure means we only make more when your P&L does.
What's the typical timeline to see meaningful growth?
Leading indicators — CTR, landing page conversion rate, email/SMS revenue share, 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 90–120 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 2–3 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 actually compounding instead of sitting in whatever channel was budgeted at the start of the quarter.
What size brand is a good fit for a growth marketing agency?
Most of our full-funnel engagements start with brands doing $500K–$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 — we'll tell you that directly on the first call rather than overselling scope you don't need yet.
How many channels should we run at once?
Most brands are better served running 2–3 paid channels deeply (usually Meta plus Google, with TikTok or an emerging channel as a test budget) alongside retention and CRO, rather than spreading thin across five channels with no channel getting enough spend to reach statistical significance. We build the channel mix around your AOV, margin, and existing customer data — not a template.
How is this different from hiring an SEO agency or a PPC agency directly?
If you already know the one channel you need — 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 different sets of numbers themselves. Some clients start here and never need a single-channel engagement; others graduate from a channel specialist into this once they've outgrown a single-channel scope.
Do you work with healthcare brands, or only 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. Our healthcare engagements run the same paid, retention, CRO, and analytics stack with compliance review built into the creative and tracking pipeline.
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 rather than forcing a migration.
Do we need to already be on Shopify to work with you?
No. Shopify and Shopify Plus is where most of our ecommerce clients live and it's where our deepest platform expertise sits, but the growth marketing engagement — paid, retention, CRO, analytics — works the same way on BigCommerce, WooCommerce, headless storefronts, or a healthcare intake funnel that isn't ecommerce at all.
What does weekly reporting actually look like?
A single dashboard and a weekly call covering revenue, contribution margin, blended MER, and channel-by-channel performance against the quarterly roadmap — not a deck of platform screenshots and vanity metrics like reach or engagement rate. If a number in the report doesn't tie back to revenue or margin, it doesn't make the report.
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 and adjust scope as your internal team grows.
