TOFU to BOFU orchestration

The best marketing agencies New York do not treat channels as separate silos. We run one full funnel plan across awareness, consideration, and conversion: CTV and video when reach is justified, hyper-personalised retargeting and nurture for mid funnel progression, and bottom funnel campaigns that tighten conversion signals and scale what works. Creative, media, CRO, and lifecycle sit under one operating rhythm, so learnings travel across channels and your unit economics improve as you scale.

Awareness with accountability

Test CTV and high impact video with defined audiences and holdouts, then scale only when you see incremental lift in branded search, traffic quality, and revenue.

Nurture and retargeting sequences

Build mid funnel journeys using segmented retargeting and email and SMS automation, so prospects see the right proof and offers instead of repetitive ads.

Conversion and retention compounding

Improve landing pages and checkout with CRO sprints, then increase LTV with post-purchase flows and upsell journeys so acquisition gets more profitable over time.

Plan my funnel

A complete department, embedded

Many teams evaluate the best marketing agencies New York and end up with a patchwork of specialists that do not share goals or data. Growthcurve gives you a complete marketing department in one package, with a clear weekly operating rhythm and a single owner for outcomes. We integrate as your internal staff, collaborate with product and sales, and keep execution moving without bottlenecks. That reduces management overhead and keeps work tied to measurable growth targets.
  • Complete team, one owner
  • Embedded with your team
  • Less overhead, more shipping

Cookieless measurement and activation

Modern New York growth depends on better first party data, not better opinions. We unify website, app, and CRM signals into usable audiences, then activate them across Google, Meta, TikTok, and programmatic. Measurement is built for a cookieless direction: GA4 event design, server-side tracking where appropriate, and incrementality testing via geo holdouts so you can separate correlation from causation. Reporting is tied to business outcomes like contribution margin, LTV:CAC, and payback.

First party data and CDP sync

Create high quality audiences from first party signals, then sync them to ad platforms with consistent definitions so targeting and reporting match your real funnel.

Server-side tracking foundations

Strengthen conversion feedback loops using server-side event routing where appropriate, keeping page speed and tracking resilience strong as cookies degrade.

Incrementality and MMM thinking

Validate channel impact with holdouts and geo tests, then use media mix logic to allocate budget across brand and performance based on incremental outcomes.

Fix measurement

Creative velocity that scales

When CPAs rise, most teams blame the channel. In practice, the constraint is usually creative throughput and offer clarity. We produce unlimited ad creative and run structured testing across formats, from UGC style vertical video to dynamic product ads. We align creative to funnel stage and feed learnings back into landing pages and retargeting sequences. With official partner access across major platforms, we apply best practices, but we still judge success by what drives revenue and retention.

UGC and vertical video formats

Create creator style assets built for Shorts, Reels, and TikTok, then iterate hooks and proof quickly to improve engagement and downstream conversion.

Dynamic product and catalogue ads

Use feed-driven ads and product sets to match users with relevant items, then refine based on margin and predicted LTV rather than only cheapest conversion.

A/B testing with clear learnings

Run disciplined tests with defined hypotheses and a simple learning log, so you stop repeating failed angles and compound what the market responds to.

Scale creative

Faster, cheaper than hiring

Hiring a full growth team in New York is expensive and slow, and most businesses still end up with skill gaps across creative, analytics, SEO, and lifecycle. With Growthcurve, you get senior experts and specialist coverage without building headcount. The team scales up or down on demand and works month to month, so you keep flexibility. This model is designed for speed: get high quality execution running quickly, then compound results through structured testing.
  • Scale team on demand
  • Monthly rolling engagement
  • Avoid hiring delays

SEO that compounds, not a checklist

Organic growth is a mix of technical hygiene, content that earns clicks, and authority building that is genuinely deserved. We treat SEO as a product, with a backlog and a cadence, rather than a one-off project. Technical work covers crawlability, site architecture, Core Web Vitals, schema markup and index management. On-page work is driven by search intent and the real questions buyers ask at each stage. Off-page focuses on link earning through useful assets, partnerships and digital PR rather than spam. For example, for a B2B brand we might build a set of comparison pages for demand capture, a small research piece to earn links, and a library of problem-led articles that support sales calls. The outcome is more qualified traffic, better brand credibility, and lower dependency on paid media over time.

Evidence-led growth operating system

Some agencies deliver activity, not progress. We run an evidence-led system designed to eliminate guesswork: define hypotheses, ship experiments, measure outcomes with resilient tracking, and document learnings so performance improves over time. Our proprietary AI marketing tools and dashboards help spot anomalies and prioritise what to fix next, while senior operators keep the plan tied to unit economics. This is how teams break through growth ceilings beyond traditional ads.
  • Hypothesis-driven experimentation
  • AI tools for faster cycles
  • Decisions tied to unit economics
How do I choose among best marketing agencies New York?
Start with your current way and what is failing: fragmented vendors, slow hiring, weak tracking, or creative fatigue. Then choose an agency that can run one accountable full funnel plan, not isolated channel work. Ask how they measure success beyond platform attribution, what their weekly testing cadence looks like, and how they report in business metrics like payback and LTV:CAC. The best partners welcome these questions and answer directly.
What does full funnel marketing include in 2026?
Full funnel means coordinated work across awareness, consideration, conversion, and retention. Practically, that includes video and reach where justified, search and shopping to capture demand, paid social and retargeting to nurture, plus CRO and lifecycle to improve conversion and LTV. It also includes modern measurement: first party data, resilient tracking, and incrementality testing so you can allocate budgets based on causal impact, not noisy last click views.
Do you run CTV, DOOH, and programmatic in NYC?
Yes, when the budget and measurement plan make sense. CTV and DOOH can be valuable for reach, but they should be treated as testable investments with clear audiences, frequency controls, and success criteria. We connect upper funnel activity to downstream outcomes using geo experiments, holdouts, and cohort movement. If your business cannot yet measure or sustain upper funnel spend, we typically prioritise demand capture first.
How do you handle cookie loss and iOS attribution issues?
We focus on stronger first party measurement and cleaner conversion signals. That usually includes GA4 event design, enhanced conversions where available, and server-side tracking where appropriate to improve resilience and data quality. Then we validate performance using incrementality approaches like geo holdouts. This reduces reliance on platform-reported attribution, which can over-credit retargeting and undercount cross-device journeys as cookies and identifiers degrade.
How do you optimise for customer lifetime value, not just CAC?
We align campaigns to value signals and downstream quality, not just the cheapest conversion. That can include value-based bidding inputs, audience segmentation built from first party behaviour, and creative that qualifies the right users. We also improve LTV directly through lifecycle work: onboarding flows, win-back sequences, post-purchase journeys, and upsell paths. Success is measured in payback and contribution margin, not only top-line volume.
What does your creative testing process look like each week?
We run a structured testing cadence with hypotheses, variants, and a simple learning log. Each week we focus on a small set of variables, such as hook, proof, offer framing, and format, so results are interpretable. Unlimited creative production is included, which prevents testing velocity from stalling. We promote winners into broader spend and retire fatigued assets quickly, keeping performance stable as budgets scale.
Can you support both DTC eCommerce and B2B SaaS?
Yes, but the funnel design and success metrics differ. For DTC, we focus on merchandising, creative throughput, landing speed, and post-purchase retention to raise contribution margin. For B2B SaaS, we focus on lead quality, stage conversion, and pipeline attribution. We tailor channels and measurement accordingly, from shopping and dynamic product ads to intent and ABM style targeting. The operating system stays consistent: test, measure, and compound learnings.
Do you charge commission on ad spend?
No. We do not charge commission fees on your ad spend. That keeps incentives aligned and avoids the common situation where an agency earns more simply because you spend more. Your fees reflect the team and work required to hit outcomes. It also gives you flexibility to scale budgets up or down without renegotiating compensation structures, and it makes it easier to evaluate performance on results rather than media volume.
How quickly can you onboard and start delivering improvements?
We start with an audit across tracking, accounts, creative, landing pages, and unit economics, then prioritise the few changes most likely to unlock performance. Early wins often include conversion signal fixes, account structure clean-up, and a creative refresh. From there, we move into a steady weekly cadence of tests and improvements.

Lifecycle marketing that increases LTV

If you only optimise acquisition, you end up paying more for the same customers. We build lifecycle systems that raise retention and expansion, using email, SMS where relevant, and CRM workflows that feel personal without being creepy. We set up segmentation based on behaviour and value, then design flows for onboarding, activation, replenishment, win-back and referral. In practice that can include RFM modelling for ecommerce, lead scoring for B2B, or product usage triggers for SaaS. We also help you capture first-party and zero-party data with preference centres and progressive profiling, so targeting stays resilient as privacy changes. When we ran a lifecycle audit for one team, we found revenue sitting in overlooked moments, like post-purchase education and renewal risk signals. The outcome is a healthier blended CAC and a marketing engine that keeps paying you back.

Measurement you can trust and use

Attribution arguments waste time and block good decisions. We set measurement up so it is good enough to guide spend, creative and roadmap choices, and we are honest about what is knowable. Tracking work can include GA4 hygiene, conversion event design, server-side tracking where appropriate, and consistent UTMs. Reporting lives in a real-time dashboard, with views that match how you run the business, such as channel performance, funnel conversion, cohort retention and creative learnings. We also use incrementality thinking where it matters, like geo holdouts or controlled tests for bigger budget shifts. For example, if brand search rises after a video push, we look at the whole picture rather than declaring victory based on last click. The outcome is faster iteration and fewer surprises in board meetings.

Operating rhythm, SLAs and ways of working

Good marketing is mostly good operations. We set a working rhythm that keeps delivery moving and prevents strategy decks from becoming a comfort blanket. You get a named lead, specialist channel owners, and access to top-tier US and UK talent, scaled up or down based on your needs. We agree response times, approval flows and who owns what across creative, landing pages, tracking and budget changes. Campaign planning happens in short cycles, with clear priorities and a shared backlog, so work does not disappear into a black box. We also help your internal stakeholders, like product, sales and finance, stay aligned with what marketing is doing and why. The outcome is a calm, consistent cadence, less context switching, and a team that behaves like your internal staff while staying on a monthly rolling basis.
