SiriusDecisions

SiriusDecisions, now part of Forrester, is a global B2B research and advisory firm that has shaped how many organizations think about sales, marketing, and product alignment. Known for pioneering frameworks like the Demand Waterfall, the company provides data-driven intelligence, benchmarks, and consulting to help B2B leaders modernize their go-to-market operations. Its acquisition by Forrester in 2019 expanded its reach while preserving the specialized focus that made it a trusted name among mid-market and enterprise teams.

The core offering revolves around a large library of B2B research covering account-based marketing, demand creation, channel strategy, customer engagement, and product management. What sets SiriusDecisions apart is its proprietary methodology: the Demand Unit Waterfall, alignment models, and the SiriusIndex benchmarking platform. These tools give clients a structured way to measure performance, identify gaps, and prioritize investments. The Command Center portal provides access to hundreds of peer-based metrics, making it possible to compare funnel efficiency, budget allocation, and team productivity against similar organizations.

Pricing is custom and not publicly disclosed, which is typical for high-touch advisory services. Subscriptions are scoped based on the number of users, the breadth of research access, and the level of analyst engagement. Consulting projects and learning programs are priced separately. While the investment is significant, organizations that fully adopt the frameworks often report improved alignment between revenue teams and clearer accountability for pipeline generation. There is no free plan or self-serve tier, so the model is best suited for companies that can commit to an annual engagement.

SiriusDecisions is best for mid-market and enterprise B2B companies that want a research-backed operating model to align marketing, sales, and product. It is especially valuable for organizations undergoing a growth phase or a transformation in how they approach demand generation. The depth of benchmarking data and the prescriptive, role-based guidance make it a strong fit for CMOs, sales operations leaders, and product marketing teams who need more than generic advice. Smaller startups or teams with limited budgets may find the cost and implementation effort too high, and lighter alternatives like Gartner or specialized boutique firms might be more practical.

The main drawbacks are the complexity of operationalizing frameworks like the Demand Unit Waterfall and the annual subscription model. Teams that lack strong data infrastructure or change management support may struggle to realize the full value. Additionally, the engagement is oriented around consulting and research access rather than a software product, so teams looking for a quick, self-serve tool will be disappointed.

Overall, SiriusDecisions remains a gold standard for B2B go-to-market strategy. Its frameworks have been adopted by thousands of organizations, and the benchmarking data is among the most comprehensive available. For companies ready to invest in a structured, analyst-backed approach to revenue performance, it delivers a clear return through better alignment, measurable improvements in funnel metrics, and a shared language across departments.
