World's first Platform Based Agency!

Weblish is a platform based agency officially launched in 2025 after seven years of building for small and midsize businesses. We unite design, content, search, and measurement in one place so founders work with one accountable partner and follow a calm path from idea to launch.

Our roots go back to 2018, helping teams clean up their web presence, sharpen offers, and ship pages that feel fast, trustworthy, and easy to use. Those early projects shaped our culture. Fewer handoffs. Fewer vendors. Clear decisions. Steady delivery.

Today we offer four connected services. Web Design and Development provides a modern and extensible foundation. Search Engine Optimization creates dependable discovery over time. Newsletter campaigns nurture relationships and bring customers back. Social Media Marketing keeps brands present and credible. Every engagement benefits from our shared design system, component library, and quality checks tuned for real devices and real users.

The process is simple and calm. Discover and define. Write and design. Build and refine. Launch and improve. Reporting shows what is working and what to adjust next in plain language. If you want reliability without complexity, Weblish is a partner you can count on year after year.

#1 Subscription-Based Digital Marketing Company

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 redefining the agency game, by providing the same quality of service as a big, fancy agency, without the same snooty energy (or the same delays in producing deliverables, or forcing you to connect with ten different people before getting an answer).
