Full funnel growth engine

The best marketing agency New York is rarely the one that only does one thing well. We run an integrated full funnel plan across demand generation and demand capture: video and reach when you need awareness, paid search and Performance Max to capture intent, and paid social to scale winners with fast creative iteration. We connect those channels to CRO and lifecycle so results compound. You get one accountable team instead of multiple vendors pulling in different directions.

TOFU that feeds demand capture

Use YouTube, CTV, and programmatic for controlled reach, then measure downstream impact with cohorts and tests so awareness spend supports revenue.

MOFU retargeting with intent

Build segmented retargeting and nurture sequences that match buyer stage, with frequency controls, exclusions, and creative sequencing to avoid wasted impressions.

BOFU conversion and retention

Improve landing pages and onboarding, then use email and SMS automation to lift repeat revenue and payback, so scaling does not break unit economics.

Plan my funnel

Faster than in-house builds

Hiring in New York is slow, and building a full growth team usually means gaps across creative, media, analytics, and lifecycle. Growthcurve gives you a complete marketing department that integrates with your internal staff. We move quickly because the team, playbooks, and tooling are already in place, so you can start testing and learning without months of recruitment. You keep control of strategy while we execute and iterate week by week.

Post privacy measurement stack

In 2026, selecting the best marketing agency New York means asking how they measure performance in a low-signal world. We improve attribution quality with server-side tracking where appropriate, first party event design, and GA4 enhanced conversions that feed better bidding signals. When budgets warrant it, we add incrementality testing such as geo lift or holdouts to validate true impact. Reporting focuses on cohorts, LTV:CAC, and payback, not just last click numbers.

Server-side and first party signals

Strengthen conversion signals for Meta and Google with clean events and first party capture, so optimisation reflects real revenue quality, not noise.

Incrementality, not assumptions

Use holdouts and geo experiments to separate correlation from causation, then reallocate budget based on proven lift across channels.

Dashboards for real decisions

Combine ad platforms with analytics and CRM to monitor funnel leakage and cohort performance, then use regular reviews to prioritise the next highest ROI fixes.

Creative and platform execution

Growth in New York markets is often constrained by creative velocity and offer clarity. We produce unlimited ad creative and run structured testing across Meta, TikTok (including Spark style formats and shopping integrations where relevant), YouTube, and LinkedIn. We match creative to funnel stage: TOFU video hooks, MOFU proof and education, BOFU direct response and conversion assets. As official partners across major platforms, we follow best practices while staying ruthless about what actually performs.

UGC and shoppable formats

Build creator style ads and shoppable flows for the platforms that support them, then amplify winners to improve trust and reduce friction to purchase.

Creative testing system

Use a repeatable framework for hypotheses, variants, and learnings so your team stops guessing and starts compounding what the market responds to.

Channel-specific messaging

Adapt positioning and proof for each platform, from LinkedIn thought leadership funnels to Meta direct response, without losing brand consistency.

Scale creative

Built for scaling teams

The best marketing agency New York should feel like a capability upgrade, not a vendor you chase. We bring senior specialists across paid media, creative, analytics, SEO, and CRO, then scale resources up or down based on the bottleneck of the month. There are no long-term contracts, so you keep leverage and flexibility. This is designed for founders and marketing leads who need outcomes and clarity, not endless meetings and ambiguous deliverables.
  • Top US and UK talent
  • Monthly rolling engagement
  • Scale support on demand

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 optimisation cadence

Most agencies talk about being data-driven, but they still rely on opinions and platform defaults. We run an evidence-led cadence: define hypotheses, ship tests, measure with reliable signals, and document learnings so performance improves over time. Our proprietary AI marketing tools and performance dashboards help surface anomalies and prioritise what to fix next, while senior strategists keep the plan aligned to unit economics. This reduces wasted spend and accelerates learning.

How do I choose the best marketing agency New York?
Start with your use case and constraints: growth stage, margins, and what is currently blocking scaling. Then assess whether the agency can run full funnel work with one accountable plan, not disconnected channel teams. Ask for their measurement approach in a post privacy world, how they run structured testing, and how they report results in business terms like payback and LTV:CAC. Avoid agencies that optimise to impressions and clicks without revenue quality.
What should a full funnel plan include in 2026?
A practical full funnel plan includes demand generation (video and reach where it is justified), demand capture (search, shopping, and paid social), and conversion plus retention (CRO and lifecycle). It also needs a clear measurement stack. For many brands, this means pairing Performance Max and search with Meta and TikTok, adding retargeting and email and SMS sequences, and validating channel impact with incrementality methods when scale allows.
Do you work with TikTok Shop, Performance Max, and Amazon DSP?
Yes, when it fits your business model and margins. TikTok commerce integrations can work well for certain consumer products, while Performance Max is useful when your conversion tracking and feed quality are strong. Amazon DSP can be relevant for brands with Amazon presence or category competition. We do not force channels. We evaluate where your customers actually buy, what data signals you can provide, and what tests can prove incremental lift.
How do you handle tracking and attribution after iOS changes?
We focus on stronger first party signals and cleaner measurement. That can include server-side event routing where appropriate, GA4 enhanced conversions, consistent event naming, and tighter conversion definitions that reflect revenue quality. Then we validate performance with incrementality approaches such as holdouts or geo tests, especially when you are investing in upper funnel channels. This reduces reliance on last click models and platform-reported attribution alone.
What does your CRO process look like in practice?
We start by identifying where users drop out of the funnel, using analytics plus qualitative behaviour from heatmaps and session replay equivalents. We prioritise tests by expected impact and effort, then ship improvements in short cycles. Testing can include landing pages, offers, checkout, pricing pages, and onboarding flows. The aim is to raise conversion and revenue per visitor so paid and organic traffic become more profitable to scale.
How do you ensure creative quality while moving fast?
Speed comes from a repeatable creative system, not rushed work. We align on brand guardrails and approval routes, then run a structured testing plan that defines what we are learning each week: hooks, proof, offers, formats, and objections. Unlimited creative production is included, so you can iterate without waiting on a separate vendor. We document learnings to avoid repeating ideas that do not perform.
Do you charge commission on ad spend or take kickbacks?
No. We do not charge commission fees on your ad spend. That keeps incentives aligned and makes forecasting easier as budgets change. Your fees reflect the team and the work required, not how much you spend on media. It also helps keep decision-making objective: we can recommend reducing spend, reallocating channels, or pausing campaigns when the data says it is the right move.
How quickly can we see progress after onboarding?
You can usually expect early progress from fixing foundations and removing obvious waste: tracking clarity, account structure, creative refresh, and landing page friction. Those improvements can be identified quickly and implemented in weeks. Sustainable scaling still requires structured testing and enough data volume to learn. We set expectations upfront with a prioritised roadmap, weekly execution cadence, and clear definitions of success tied to unit economics. Book a call
What types of companies are you best suited to?
We are best suited to founders and marketing leaders who want a hands-on growth partner that can execute across channels and reporting, without building a large in-house team. The model works well for venture-backed startups, scaling ecommerce brands, and B2B teams that need consistent testing. We are not a fit if you only need a one-off campaign with no measurement plan, or if you want a long fixed contract regardless of results and priorities.

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.
