Full Cortex is a Boston-based growth agency specializing in full-funnel growth marketing for B2B, SaaS, and tech-driven companies. They help acquire more customers, increase conversion rates, and scale revenue with measurable results across both digital platforms and mobile apps.
Full Cortex is a Boston-based growth marketing agency that positions itself as a full-funnel partner for B2B, SaaS, and tech-driven companies. Founded in 2015, the agency has built a reputation for combining strategic depth with hands-on execution, serving clients ranging from early-stage startups to established enterprises. Their approach starts with a thorough audit of the existing marketing funnel, identifying friction points and growth levers before designing a tailored strategy.
The agency's service offering is unusually broad, covering everything from AI search optimization and LLM optimization to traditional SEO, PPC, content marketing, email automation, and even web development and UX design. This breadth allows Full Cortex to act as an one-stop shop for companies that need a cohesive growth engine rather than point solutions. Notably, they also offer app store optimization (ASO) and user acquisition for mobile apps, a capability that sets them apart from many generalist B2B agencies.
Full Cortex emphasizes a collaborative, embedded model. They describe themselves as becoming "an extension of your team," working closely with internal stakeholders across marketing, sales, customer success, and product. They also support investor reporting and KPI tracking, which is particularly valuable for funded startups that need to demonstrate growth to stakeholders. Their project budgets typically range from $2,500 to $5,000, with engagements lasting more than six months, indicating a preference for long-term partnerships over one-off projects.
The agency is best suited for B2B SaaS and tech companies that need a comprehensive growth strategy spanning both digital marketing and mobile app channels. Their experience with app store optimization and user acquisition makes them a strong fit for companies with a mobile product or app component. Early-stage startups looking to reach product-market fit, as well as post-Series A companies aiming to accelerate growth, will find their frameworks and execution capabilities aligned with their needs.
While Full Cortex offers an impressive range of services and a data-driven methodology, the lack of public client reviews or detailed case studies on their Semrush profile makes it harder to validate their track record. The pricing range, while accessible, may be on the lower end for the full scope of services they advertise, though the long project duration suggests they deliver value over time. Their team size of 10-49 is agile but may limit capacity for very large enterprise engagements.
Overall, Full Cortex is a solid choice for growth-stage B2B tech companies that want a single partner to orchestrate their entire growth funnel, especially if they have a mobile app component. Their collaborative approach and emphasis on measurable results make them a practical option for companies that need both strategy and execution under one roof.
