OIESU — AI-Assisted PPC and Lead Generation Agency

What is OIESU?

OIESU is a performance marketing and software development agency based in Kolkata, India, that runs paid advertising and lead generation for businesses. The site states the company was founded in 2021, with team delivery experience it traces back to 2012. Its core service is managed advertising across Google Ads, Meta Ads, Microsoft Ads, LinkedIn Ads, and YouTube Ads, supported by SEO, web design, landing pages, content, email, WhatsApp, influencer, and brand marketing. OIESU also offers white-label delivery for other agencies.

A distinguishing claim is its delivery method: the site describes an agentic workflow stack that combines 15+ AI models with tools such as Claude, n8n, Zapier, and LangChain to plan and operate campaigns. Self-reported figures include "$1B+ in managed ad spend," "5M+ qualified leads generated," and more than 500 businesses served — the site presents these as aggregate team and partner history rather than independently audited results.

How OIESU Works

Engagement follows a published timeline. On day 0, a prospective client requests a free audit covering their ads accounts, landing pages, and competitors. From days 1 to 4, the team builds strategy, funnels, tracking pixels, and audiences. Campaigns launch between days 5 and 7 with verified tracking. After launch, OIESU describes 24/7 monitoring, weekly calls, and monthly performance reviews.

Pricing is set on a free 30-minute call. The site says it charges a flat monthly management fee — explicitly not a percentage of ad spend — and prices web design and landing pages as projects. Contracts are month-to-month and can be cancelled with 30 days' notice. The company serves clients remotely and lists reach across the US, UK, UAE, Australia, Canada, Singapore, and the EU.

Main Features

• Multi-platform paid campaign management — Google, Meta, Microsoft, LinkedIn, and YouTube ads planned and operated by the agency team.
• AI-assisted delivery — the site describes 15+ AI models plus an agentic stack (Claude, n8n, Zapier, LangChain) used in campaign operations.
• Free audit and strategy call — a no-cost review of ads, landing pages, and competitors before any commitment.
• Landing pages and web design — conversion surfaces built and priced as discrete projects.
• White-label delivery — campaign management resold by other agencies under their own brand.
• Reporting cadence — weekly calls, monthly reviews, and 24/7 campaign monitoring as described on the site.

Pricing

OIESU does not publish prices. Its model is a flat monthly management fee for ongoing campaign work — the site is explicit that the fee is not calculated as a percentage of ad spend — while web design and landing-page work is priced per project. The actual amount is quoted only after a free 30-minute strategy call. Contracts run month-to-month with cancellation on 30 days' notice. There is no free service tier; the free audit and strategy call are the only no-cost offerings.

Common Use Cases

• Lead generation for local and regulated services — the site lists law firms, healthcare and dental, real estate, med spas, hotels, coaching, local services, and immigration.
• SaaS and B2B pipelines — paid search and social programs aimed at qualified pipeline rather than vanity traffic.
• iGaming acquisition — listed among the verticals the agency serves.
• Agency white-labeling — other agencies reselling OIESU's campaign delivery under their own brand.
• Conversion infrastructure — businesses that need landing pages or a site rebuild alongside their ads.

Limitations

Pricing is entirely sales-gated, so buyers cannot compare cost before a call. The headline metrics ($1B+ ad spend, 5M+ leads) are self-reported and not independently audited, and the site acknowledges its case studies are anonymized by NDA, which makes references hard to verify. OIESU is a service business, not a self-serve tool — there is no dashboard signup, free trial of the service, or published SLA or performance guarantee. Claims like "100× faster" are marketing language rather than documented benchmarks. Finally, as an agency engagement, results depend heavily on the assigned team and the client's offer and budget.

Summary

OIESU is a full-service paid-ads and lead-generation agency from Kolkata that leans on an AI-heavy internal workflow and covers the major ad platforms plus landing pages and SEO. Its published onboarding timeline, flat-fee positioning, and free audit make it easy to evaluate, and white-label delivery widens its use to other agencies. The trade-offs are typical of agencies rather than software: no published pricing, self-reported results, anonymized case studies, and no performance guarantees. It best fits businesses that want to outsource lead generation entirely and are willing to vet the agency through its free audit and call before committing.
