Growth Kings overview

Growth Kings is a digital growth agency operating under the tagline "More leads, by design." The agency is built specifically to help established service businesses turn website visits into qualified enquiries. Rather than offering generic or sprawling marketing campaigns, Growth Kings zeroes in on practical website improvements, search and AI visibility, and AI-powered enquiry assistants. The company is led by co-founders David Vinicius, who serves as Growth Director, and Byrone Lehmann, who acts as Creative Director.

The agency's client base primarily consists of established client-facing service businesses such as legal practices, dental clinics, medical practices, trades, and property and lettings companies. When working with Growth Kings, clients deal directly with the founders rather than being handed off to junior account managers. Their delivery model centers on a clear three-step engagement: first, they understand the business and its current obstacles; second, they agree on a written scope and fixed price; third, they build, test, and measure the results.

Growth Kings positions itself as an honest partner. They are transparent about whether they are the right fit for a business and do not push unnecessary full website rebuilds when practical fixes will achieve the goal. Their technical strengths include structured data, technical SEO foundations, useful service pages, and AI assistants capable of handling after-hours lead capture with built-in human handoff for sensitive topics. However, as a younger company, they have limited proprietary case studies under the Growth Kings brand and do not guarantee specific search rankings, AI mentions, or conversion rates.

Disruptive Advertising overview

Disruptive Advertising is an established performance marketing and advertising agency operating under the tagline "Performance Marketing With Purpose." With a team of over 160 employees, the agency has built a substantial footprint in the digital marketing industry, reflected by its position at #145 on the Inc. 500 and a history of managing over $450M in annual ad spend. They are recognized as a top-reviewed digital marketing and advertising agency in the USA.

The agency serves business owners and marketing leaders looking to outsource or scale their digital marketing across B2B, B2C, eCommerce, local businesses, SaaS, online education, and high AOV brands. Disruptive Advertising's core philosophy centers on aligning data integrity, tracking, and attribution with performance marketing goals. Their team holds extensive experience in scaling paid traffic channels and optimizing user journeys for maximum revenue return.

Operationally, Disruptive Advertising is built for scale. They utilize a structured 6-step new client onboarding and strategy timeline and offer a 90-day growth guarantee for qualifying brands. While they boast a high volume of positive client reviews on platforms like Clutch and maintain strong partnerships with major platforms like Google Ads and Shopify, they also turn away a high percentage of prospective clients during their vetting process to ensure a strong strategic fit. Custom pricing quotes are provided on request, and they offer free marketing and analytics audits to prospective clients.

Services compared

Comparing the service offerings of Growth Kings and Disruptive Advertising highlights a fundamental difference in agency scope. Growth Kings provides targeted digital growth services designed to fix website conversion bottlenecks and capture leads. Their core services include search and AI visibility optimization, conversion-focused website design and fixes, and AI enquiry assistants with human handoff. They also support technical SEO foundations, useful service pages, structured data, after-hours lead capture, and calendar or CRM integration support.

In contrast, Disruptive Advertising delivers a broad suite of performance marketing and advertising services. Their capabilities include paid search advertising, paid social marketing, search engine optimization, Amazon marketing, lifecycle marketing, conversion rate optimization (CRO), creative services, and data analytics with custom tracking. While Growth Kings focuses heavily on the onsite experience and turning existing traffic into enquiries, Disruptive Advertising focuses heavily on driving external paid traffic, scaling advertising budgets, and managing complex multi-channel data analytics.

For an established dental practice or law firm looking to convert visitors into phone calls and bookings, Growth Kings provides direct, conversion-centric solutions. For an eCommerce brand or SaaS company looking to spend tens of thousands of dollars monthly on paid acquisition across Google and Meta, Disruptive Advertising provides the specialized media buying and analytics infrastructure required.

Pricing and engagement model

The pricing and engagement models of both agencies reflect their distinct business designs. Growth Kings utilizes a straightforward fixed-fee structure. Project work is thoroughly scoped and quoted as a fixed fee agreed upon before any work begins, ensuring clients do not receive surprise invoices. Ongoing support is discussed, priced, and agreed separately from initial project deliverables. This structure gives smaller service businesses cost predictability and clear boundaries on what will be delivered.

Disruptive Advertising operates on a custom quote model. Because their engagements often involve managing substantial ad budgets, complex data analytics, and multi-channel campaigns, prices are quoted on request after initial audits and discovery. To assist prospective clients in evaluating potential partnerships, Disruptive Advertising offers free marketing and analytics audits. They also feature no long-term contracts and offer a 90-day growth guarantee for qualifying brands.

When choosing between the two, budget holders must weigh predictability against scale. Growth Kings provides clear project-based fees ideal for defined website improvements. Disruptive Advertising requires custom budgeting tied to media spend and comprehensive marketing management, backed by performance guarantees for qualifying accounts.

Process, team and results

Examining team structure and delivery processes reveals further operational differences. Growth Kings is a boutique operation run directly by co-founders David Vinicius and Byrone Lehmann. Clients work directly with the leadership team rather than being delegated to junior account managers. Their three-step process—understanding the business and obstacle, agreeing to a written scope and fixed price, and building, testing, and measuring—keeps projects lean and focused.

Disruptive Advertising relies on a large-scale organizational structure with over 160 employees. Their onboarding follows a formal 6-step new client onboarding and strategy timeline designed to align data integrity with overarching growth goals. Their credentials include managing over $450M in ad spend and securing #145 on the Inc. 500 list, supported by extensive reviews on platforms like Clutch.

Regarding results and guarantees, Growth Kings is upfront about its limitations, noting that they do not guarantee specific search rankings, AI mentions, or conversion rates, and acknowledging their status as a young company with limited proprietary case studies under the brand. Conversely, Disruptive Advertising leverages its scale to offer a 90-day growth guarantee for qualifying brands, though they maintain a high rejection rate for prospective clients who do not meet their fit criteria.

Who each one is really for

Determining which agency is right for your organization depends entirely on your business type, current bottlenecks, and growth strategy. Growth Kings is built for established client-facing service businesses—such as legal practices, dental and medical clinics, trades, and property and lettings agencies—that already receive some web traffic or local interest but struggle to turn those visits into qualified enquiries. It suits business owners who want direct access to founders, practical website enhancements, technical SEO foundations, and AI enquiry assistants without signing up for expensive, ongoing enterprise marketing retainers.

Disruptive Advertising is built for business owners and marketing leaders looking to outsource or aggressively scale paid digital marketing across search, social, and eCommerce channels. It suits B2B, B2C, eCommerce, SaaS, and high AOV brands that have budgets for ad spend, require rigorous data analytics and attribution tracking, and benefit from a large team of specialists managing campaigns. Brands that qualify can also leverage their 90-day growth guarantee.

In summary, if your primary obstacle is website conversion and lead capture for a local service business, Growth Kings is the tailored fit. If your primary obstacle is scaling customer acquisition through paid advertising and advanced data analytics across regional or national markets, Disruptive Advertising is the established choice.
