Instagram Advertising Agencies in New York City, NY

Ninja Promo is a full-service digital marketing company built around subscription-based dedicated marketing teams. Instead of traditional agencies that bill per project or freelancers with limited bandwidth, you get a stable cross-functional team on a flexible monthly subscription.

CMO-on-demand, strategists, project managers, designers, content creators, media buyers, and analysts work as one unit, giving you predictable costs, faster execution, and the impact of an in-house team without the hiring overhead.

We deliver full-cycle digital marketing across all key channels and disciplines. From market research, positioning, and brand strategy to design, creative and content production (including video), performance marketing, SEO, paid advertising, content marketing, social media, influencer marketing, PR, web and landing page development, and analytics - we run your marketing operations end to end under one roof. Our integrated approach keeps strategy, creatives, and media aligned, so every campaign supports your growth targets, whether you need one core service or a complete marketing transformation.

We work with companies across multiple industries because we believe real marketing expertise is not about being locked into a single niche, but about the ability to research, understand, and win in any market. Our teams follow a research-driven playbook: deep industry and competitor analysis, understanding regulations and audience behavior, and rapid testing to find what truly converts. This approach has already delivered proven results in B2B and SaaS, crypto and Web3, fintech and financial services, IT and software, gaming and iGaming, e-commerce, real estate, healthcare, forex, AI and more, with new verticals constantly added to our portfolio. Cross-industry experience lets us transfer successful tactics from one sector to another, giving our clients an advantage that single-industry agencies simply cannot provide.

We’re proud to be a strategic partner to some of the very best brands on the planet, helping them stay relevant, conversational, and advocated—all at the speed of social.

Think of us as your tech partners in crime: whether you need a landing page that converts like crazy, an e-commerce platform smoother than a jazz riff, or a 3.js-powered visual masterpiece that makes competitors sweat, we’ve got your back.
