Complete marketing team, one
Unlimited creative iterations

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.

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.

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.

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.

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.

  • AI tooling for speed
  • Dashboards for accountability
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.
