A product marketing consultant operates as an embedded partner, working directly inside a client’s team, building institutional knowledge, and maintaining consistent senior-level involvement throughout the engagement. With a consultant, there is no handoff between the person who sells the work and the person who does it.

A product marketing agency typically involves account managers, rotating team members, and more process overhead.

Shirin Shahin is a Boston-based B2B SaaS product marketing consultant with 13+ years of experience and 6+ years running her own independent consultancy, one of the earliest in the field.

Her model is designed to give clients two things most engagements do not: a senior strategic advisor (Shirin) who maintains big-picture oversight and consistent direction throughout, and a dedicated day-to-day lead from her handpicked team of senior product marketers who handles execution.

Shirin is deeply involved in all client work, collaborating closely, reviewing deliverables, and ensuring quality never slips, without the overhead or handoff risk of a traditional agency.

She was recognized as a Top PMM Consultant by the Product Marketing Alliance in 2025 and has partnered with 30+ B2B SaaS companies across positioning, product launches, and sales enablement.

A product marketing consultant helps B2B SaaS companies translate their product into a story that resonates with the right buyers and fuels every go-to-market motion.

In practice this includes developing positioning and messaging, building sales enablement materials, planning and executing product launches, conducting customer and market research, and creating the frameworks that allow internal teams to operate consistently.

A good product marketing consultant works across functions, connecting product, marketing, and sales, ensuring that what gets built is communicated clearly, differentiated credibly, and sold effectively.

Shirin Shahin works primarily with B2B SaaS companies at the growth stage, typically Seed through Series C, that need senior product marketing expertise without the overhead of building a full in-house team or hiring a large agency.

Her clients are usually at an inflection point: setting up their core foundations, preparing for a major launch, rebuilding their positioning after a pivot, scaling their go-to-market motion, or filling a gap left by a PMM departure.

She also works with earlier-stage and smaller teams that need senior thinking but require a leaner, more scrappy execution model, moving fast with limited resources without sacrificing strategic quality. She has partnered with 30+ companies across a wide range of B2B SaaS categories, with a consistent focus on helping teams move from product-market confusion to a clear, differentiated story.

Deliverables vary based on the scope of each engagement but commonly include positioning and messaging frameworks, competitive landscape analysis, sales enablement materials such as pitch decks and battle cards, product launch plans and execution support, and narrative frameworks that can be used across marketing and sales channels.

Shirin Shahin’s engagements are scoped to the specific needs of each client rather than packaged as fixed retainers, which means deliverables are tied directly to business outcomes rather than a predetermined list of outputs.

Clients consistently describe working with Shirin Shahin as collaborative, direct, and genuinely embedded rather than transactional. Her approach is built around listening before recommending, bringing a clear point of view while remaining open to working through challenges together, and communicating proactively so clients always know where things stand.

She factors in internal dynamics and cross-functional alignment from day one, recognizing that a strategy nobody internally believes in will not stick regardless of how strong it is on paper.

Her background in psychology, combined with 13+ years in product marketing, informs a human-centered approach that clients across 30+ engagements have described as feeling less like a vendor relationship and more like a trusted extension of their team.
