Mann Marketing in Baltimore: Full-Service Agency for Mid-Market B2B Growth

Mann Marketing is a Baltimore-based full-service marketing agency that serves mid-market B2B companies across the Mid-Atlantic, with a focus on strategy, paid media management, and lead generation rather than creative production alone.

What Mann Marketing actually does

Mann Marketing operates as a retained marketing partner for companies with $5 million to $100 million in revenue, handling campaign strategy, paid search and social advertising, conversion optimization, and reporting. The firm works primarily with industrial, manufacturing, professional services, and technology firms. The agency is locally rooted and works with clients both in and outside Baltimore, including across the region's defense contracting, life sciences, and logistics sectors.

Services and pricing structure

Mann Marketing works on a retainer model rather than project-by-project engagement. Retainer fees typically start at $3,500 per month for foundational paid search management and account strategy, scaling to $8,000–$15,000 per month for comprehensive digital strategy that includes paid media across Google and LinkedIn, conversion rate optimization, and monthly performance reporting. The agency charges by the hour for one-off consulting (around $150–$200 per hour) and strategy workshops that help clients define their ideal customer profile or messaging hierarchy before committing to a full retainer.

The agency does not produce creative assets in-house; instead, it partners with freelance designers and copywriters or refers clients to specialized creative shops. This structure keeps retainer costs lower but means clients planning a major rebrand or video campaign will need to budget separately for production.

How Mann Marketing compares to other Baltimore marketing agencies

Baltimore has several established marketing agencies, but they operate at different scales and specialties. Tierney, a large integrated shop based in the city, handles creative, brand strategy, and media across consumer and B2B clients, with retainers typically starting at $10,000+ per month and suited to larger enterprises. Medley, another local firm, focuses on healthcare and life sciences marketing and is more creative-heavy.

Mann Marketing differs in its narrow focus on B2B lead generation and paid performance marketing for mid-market companies. If your company is $2 million in revenue and needs a full rebrand and brand story, Tierney or a creative-first boutique is the better fit. If you are a $30 million manufacturing firm losing leads to competitors on Google and LinkedIn and need someone to audit your current campaigns and build a paid strategy, Mann Marketing's retainer model and performance focus align better. If you are in life sciences or healthcare and need deep vertical expertise, Medley may have stronger existing knowledge of your regulatory landscape.

Who Mann Marketing suits and who it doesn't

Mann Marketing works best for B2B companies with a defined product or service, a clear sales process, and the ability to measure lead quality and conversion. It suits companies that have already launched but are struggling to generate qualified leads or that have hired in-house marketing talent who need strategic guidance on channel prioritization.

The agency is not a fit for startups still validating their market, consumer brands focused on brand awareness over lead generation, or companies requiring extensive creative production. It also serves companies that expect a hands-off relationship; Mann Marketing's retainer includes monthly strategy calls and expects clients to actively participate in quarterly business reviews.

What the first engagement looks like

Initial meetings focus on understanding the client's sales cycle, current lead sources, win/loss data, and target buyer personas. The agency typically conducts a free 30-minute discovery call to assess fit. If both parties agree to move forward, Mann Marketing builds a paid search and social media audit (1–2 weeks) that benchmarks current performance against industry norms and identifies quick wins. A formal engagement kicks off with a 90-day strategy and campaign launch plan, with the first results typically visible in paid search within 6–8 weeks and LinkedIn lead generation within 10–12 weeks, depending on the sales cycle length.

Hours, location, and logistics

Mann Marketing operates from an office in Canton, Baltimore. The firm works with clients across phone, email, and video calls; most engagements do not require in-person presence, though the agency welcomes local clients to attend quarterly planning sessions on-site. Business hours are 9 a.m. to 5 p.m. Monday through Friday. Confirm current office hours and meeting policies directly before scheduling an initial consultation.

Mann Marketing fills a specific niche in Baltimore's marketing landscape: performance-driven, data-focused, and built for B2B companies mature enough to measure ROI but too lean to staff a full internal marketing department.
