The short version: if you are searching for a product marketing agency for startups, seven names cover the useful range in 2026. StartupCookie, Fletch PMM, Olivine, Punchy, Aventi Group, Kalungi, and April Dunford all do real positioning and messaging work, but they differ a lot in scope, price, and stage fit. Fletch sells a fixed-price two-week positioning sprint. Olivine is the deepest full-service product marketing bench for B2B SaaS. Punchy and April Dunford are specialists you hire for the thinking, not the execution. Aventi leans mid-market and enterprise. Kalungi sells a whole outsourced marketing function. StartupCookie (our agency, disclosure below) pairs product marketing with AI-native content production for seed to Series B B2B SaaS. This page compares all seven honestly, with published pricing where it exists and the real limitations of each, ours included.

What a product marketing agency actually does
Product marketing decides how your product is framed and sold. In practice that means four things: positioning (which market you compete in and why you win), messaging (the words your site and sales team use), launches (getting new products to market), and sales enablement (the decks, one-pagers, and battlecards your sellers need). That is different from a demand generation agency, which buys attention, and from a pure content agency, which executes a story someone else defined.
Startups usually feel the gap before they can name it: visitors do not understand the homepage, sales calls open with ten minutes of explanation, and every new landing page describes the product differently. If that sounds familiar, you need positioning work before you spend more on traffic. At StartupCookie we fold this into our product marketing service for seed to Series B B2B SaaS, but plenty of teams only need a one-off sprint from a specialist. The list below covers both.
How we evaluated this list
We looked at each firm's own public website and scored five things: startup fit, scope (strategy only, or strategy plus execution), pricing transparency, speed, and follow-through (does the story they define actually get produced anywhere). Every factual claim about a competitor below links to the source it came from, and where pricing is not public we say so instead of guessing.
1. StartupCookie: product marketing plus AI-native production, for seed to Series B
StartupCookie is an AI-native content and GTM agency for B2B SaaS. Our product marketing service covers positioning, messaging, launch planning, and sales enablement for seed to Series B startups. The difference is the model, not a claimed track record: a two-person, senior-only team (the co-founders do the work, no account managers or junior handoffs), a cap of six clients at a time, and AI-native production so the positioning we define ships as pages, posts, and sales materials instead of sitting in a slide deck. Engagements start at $5,000 per month, month-to-month, with no long contracts.
- Best for: seed to Series B B2B SaaS founders who want positioning defined and then produced by the same senior people.
- Pricing: Engagements from $5,000/mo. Month-to-month.
- Strengths: senior-only attention (a six-client cap means the co-founders stay hands-on), strategy and production under one roof, transparent starting price.
- Limitations: product marketing is a new service line for us, so we have no published client results for it yet. We only work with B2B SaaS. The model needs 1 to 2 hours of founder input per week.
- Verdict: a fit if you want one small senior team to own the story and the output. Not a fit if you want a decade of pure product marketing case studies; several firms below have that.
2. Fletch PMM: the fixed-price homepage positioning sprint
Fletch PMM sells one thing: a two-week homepage positioning sprint for B2B software startups. Per their site, the sprint delivers 4 to 6 viable positioning strategies, a six-slide internal positioning deck, and a homepage wireframe with production-ready copy. Pricing is published, which is rare in this market: $10,000 for early stage (under $2M ARR), $20,000 for growth stage ($2M to $20M ARR), and $30,000 for mature companies ($20M+ ARR). Their site shows client logos including PagerDuty, Superhuman, Synthesia, Notion, and GitLab.
- Best for: B2B software startups whose homepage no longer matches what they sell and who want a fast, bounded fix.
- Pricing: $10,000 to $30,000 fixed fee depending on stage, published on their site.
- Strengths: narrow scope, fast turnaround, transparent pricing, strong public body of positioning work.
- Limitations: the engagement ends at positioning and homepage copy. No ongoing execution, no launch retainers, no enablement program. Someone still has to carry the new story into everything else.
- Verdict: the best first purchase if positioning itself is the bottleneck and you have a team to execute afterward.
3. Olivine: the full-service product marketing bench for B2B SaaS
Olivine is a dedicated product marketing agency for B2B SaaS. Their site lists positioning and messaging, buyer personas, go-to-market strategy, sales enablement, competitive intelligence, research, brand and website design, and product marketing recruitment, with fractional support from 5 to 40 hours per week. They serve companies from pre-launch to post-IPO and name clients including LinkedIn, Twilio, ServiceNow, Envoy, and Mercury. Pricing is not published.
- Best for: B2B SaaS companies that want a complete product marketing function, or a fractional extension of one, from a team that does only product marketing.
- Pricing: pricing is not published; scoped per engagement.
- Strengths: the broadest pure product marketing service menu on this list, a long B2B SaaS client roster, flexible fractional model.
- Limitations: pricing is behind a sales call, and the breadth means you need to scope the engagement carefully.
- Verdict: the strongest full-service pick when product marketing is the whole job to be done, not one piece of it.
4. Punchy: messaging craft and team training from Emma Stratton
Punchy is the consultancy of Emma Stratton, author of the book Make It Punchy. Per their site, Punchy offers two things: positioning and messaging consulting, and interactive training that teaches teams to write clearer B2B messaging themselves. They serve B2B tech companies from growth-stage startups to global enterprises. Pricing is not published.
- Best for: B2B tech teams whose messaging reads like jargon and who want both the fix and the skill to keep fixing it.
- Pricing: pricing is not published.
- Strengths: distinctive point of view on plain-language messaging, and a training arm, which most agencies on this list do not offer.
- Limitations: consulting and training, not execution. The roster leans growth-stage and enterprise.
- Verdict: pick Punchy to level up how your whole team writes about the product, not to outsource the writing.
5. Aventi Group: product launches and enablement for mid-market and enterprise
Aventi Group is a full-service product marketing agency for B2B tech. Their site lists product launch services, go-to-market strategy, sales enablement, content marketing, and fractional leadership, with client logos including Zendesk, Atlassian, Okta, ServiceNow, and HPE. Pricing is not published.
- Best for: mid-market and enterprise B2B tech companies that need launch muscle and enablement at scale.
- Pricing: pricing is not published.
- Strengths: deep launch and enablement experience, fractional leadership options, an enterprise-grade client list.
- Limitations: the roster and service structure lean toward larger companies, not seed-stage startups.
- Verdict: the launch specialist for later-stage teams; probably more firm than a pre-Series A startup needs.
6. Kalungi: the whole marketing function, with product marketing inside
Kalungi is not a pure product marketing agency; it is a full outsourced marketing team for B2B SaaS with CMO-as-a-service on top. Their site organizes offers by stage: a playbook-driven program for pre-product-market-fit and seed companies ($0 to $1M ARR), a "we do it with you" model for $1M to $5M ARR teams, and a full-service team for $5M to $10M ARR companies. They state they have worked with over 150 SaaS companies. Positioning and messaging sit inside that broader engagement. Pricing is not published.
- Best for: B2B SaaS founders who need an entire marketing function stood up, not just product marketing.
- Pricing: pricing is not published; tiered by ARR stage.
- Strengths: stage-matched engagement models, senior CMO-level leadership, one accountable team across all of marketing.
- Limitations: product marketing is one slice of a much bigger engagement. If positioning is your only problem, this is more machinery than you need.
- Verdict: pick Kalungi when the real question is "who runs marketing here," not "who fixes our positioning."
7. April Dunford: the positioning specialist's positioning specialist
April Dunford is an individual consultant, not an agency, and the author of Obviously Awesome and Sales Pitch. Per her site, she spent 25 years as a startup marketing executive and has run her structured positioning methodology with more than 200 B2B tech companies, from growing startups to Google Cloud and Postman. The work centers on positioning and the sales pitch built from it. Pricing is not published.
- Best for: B2B tech founders and teams who want the most battle-tested positioning methodology available and will do the implementation themselves.
- Pricing: pricing is not published.
- Strengths: the deepest specialist expertise on this list, and a public methodology you can read before you buy.
- Limitations: one person, so capacity is limited and scope is deliberately narrow. No production, no launch execution, no ongoing program.
- Verdict: the premium choice for the positioning decision itself. Budget for execution separately.
Which one should a startup actually pick?
- Your homepage is the problem and you need it fixed this month: Fletch PMM. Fixed price, fixed scope, two weeks.
- You want positioning defined and then turned into content and pages by the same team: StartupCookie (see the disclosure above and judge us against this list).
- You want a complete, dedicated product marketing function: Olivine.
- Your team writes jargon and you want them to stop: Punchy.
- You are mid-market or enterprise and shipping a major launch: Aventi Group.
- You need all of marketing run for you: Kalungi.
- You want the sharpest possible answer to "what are we, and why does it matter": April Dunford.
One more option worth naming: hiring in-house instead. We wrote an honest breakdown of that trade-off in our agency vs in-house comparison; the logic maps closely to product marketing.
What none of these firms can do for you
Two honest gaps. First, no agency or consultant can position a product the founders cannot explain. Every firm on this list, ours included, needs real input from the people who know the product best. Budget one to two hours a week of founder time, or do not start. Second, positioning only pays off when it ships. A positioning deck that never becomes a homepage, a sales deck, and a stream of content is an expensive PDF. Decide upfront who carries the story into production: your team, a second agency, or a firm that does both.
Frequently asked questions
What does a product marketing agency do?
A product marketing agency settles the questions a startup has to answer before growth spend works: who the product is for, which category it belongs in, and what your site and sellers should say about it. The work usually arrives as a positioning strategy, message frameworks, launch plans, and sales tools such as decks and battlecards. Firms that buy ads or produce articles do a related but separate job; a product marketing agency supplies the story those channels run on.
How much does a product marketing agency cost for a startup?
Most product marketing agencies do not publish pricing. Among the firms on this list, two publish numbers: Fletch PMM charges a fixed fee of $10,000 to $30,000 for its two-week positioning sprint depending on company stage, and StartupCookie's retainers start at $5,000 per month. Olivine, Punchy, Aventi Group, Kalungi, and April Dunford all scope pricing per engagement, so expect a sales conversation before you see a number.
When should a startup invest in positioning work?
Invest before you scale paid traffic or grow the sales team. The warning sign is confusion: prospects cannot repeat back what you do, demos need a long setup speech, or different pages on your site tell conflicting versions of the product story. Positioning fixed early makes every later marketing dollar work harder. Fixed late, it means rewriting everything you already shipped.
Should a startup hire an in-house product marketer or an agency?
In-house wins on daily context and cross-team influence, but a senior product marketer is a slow and expensive hire to make before the need is proven. Agencies and consultants are the faster, lower-commitment way to get the positioning foundation in place. A common path is to buy the foundation from a specialist first, then hire in-house once the company is big enough to keep a full-time product marketer busy.
What is the difference between product marketing and content marketing?
Product marketing decides the story: who the product is for, what category it competes in, and why it wins. Content marketing tells that story repeatedly through articles, posts, video, and other formats. They fail without each other. Content built on weak positioning produces noise, and positioning that never becomes content stays invisible, including to AI search tools, which is why AEO (answer engine optimization, meaning getting your company cited by AI tools like ChatGPT and Perplexity) starts with clear positioning too.
