SiriusDecisions

SiriusDecisions provides specialized B2B research and advisory services, offering comprehensive guidance to executives across sales, marketing, and product functions. The company develops influential frameworks, notably the Demand Waterfall model, which serves as a widely adopted standard for managing demand generation and optimizing the lead-to-revenue funnel. Through its advisory, consulting, and learning services, SiriusDecisions equips organizations with actionable intelligence and best practices to enhance their commercial strategies and operational effectiveness.

The firm was founded in 2001 by John Neeson and Richard Eldh, who identified a critical need within the B2B landscape for structured methodologies and expert guidance. Their foundational insight centered on the lack of integrated, data-driven approaches to align sales, marketing, and product efforts. Neeson and Eldh established SiriusDecisions to provide research-backed models and strategic frameworks, empowering B2B leaders to navigate complex market challenges and achieve measurable performance improvements.

Executives across B2B enterprises leverage SiriusDecisions' research and expertise to modernize their go-to-market strategies. The company's vision is to systematically transform how sales, marketing, and product leaders collaborate and execute, fostering greater alignment and efficiency. By delivering practical frameworks and thought leadership, SiriusDecisions aims to drive superior business outcomes for its clients and shape the future of integrated commercial operations.

High-Level Overview

SiriusDecisions is a research and advisory firm specializing in operational intelligence for sales, marketing, and product executives in business-to-business (B2B) organizations.[1][2] Founded in 2001, it provides fact-based research, benchmarking, analyst inquiries, and frameworks like the "Sirius Way" to help clients align sales, marketing, and product functions, enabling 19% faster growth and 15% higher profitability compared to peers.[1][4] Acquired by Forrester in 2019 for $245 million, it now operates as the SiriusDecisions product line within Forrester, enhancing B2B strategy with data-driven tools and expanding into new verticals like financial services, healthcare, and energy.[2][4][5][6]

Origin Story

SiriusDecisions was founded in 2001 in Wilton, Connecticut, by former Gartner employees John Neeson and Rich Eldh, who identified a gap in fact-based research on B2B sales and marketing effectiveness.[1][3] The company grew to employ around 340 people, with both founders remaining involved, delivering primary research, advisory services, events, and benchmarking through online portals.[1][3] A pivotal moment came in late 2018 when Forrester announced its $245 million acquisition, closing in early 2019, integrating SiriusDecisions' operational expertise with Forrester's customer strategy focus to create a combined offering for "customer-obsessed strategies and operations."[4][5]

Core Differentiators

• B2B Operational Frameworks: Proprietary models like the "Sirius Way" and Demand Waterfall optimize sales, marketing, and product alignment with data-intensive benchmarking and continuous learning.[1][4][6]
• Research and Advisory Depth: Primary research, analyst access, peer networks, and events provide actionable intelligence, outperforming peers in growth (19% faster) and profitability (15% higher).[1][4]
• Post-Acquisition Synergies: As part of Forrester, it extends to global markets, new industries (e.g., IT, financial services), and real-time data tools, doubling Forrester's addressable market from $20B to $40B.[2][4][5][6]
• Proven Track Record: Focuses on measurable outcomes for executives, with minimal client disruption post-acquisition and expansion into B2C building blocks atop B2B strengths.[4][6]

Role in the Broader Tech Landscape

SiriusDecisions rides the trend of data-driven B2B revenue operations, addressing the need for aligned sales-marketing-product functions amid rising customer expectations in the "age of the customer."[4][6] Its timing aligns with the shift toward analytics-powered CX (customer experience) strategies, as seen in Forrester's prior buys like FeedbackNow and GlimpzIt, positioning the combined entity to lead in real-time optimization.[6] Market forces like vertical expansion (e.g., healthcare, energy) and global scaling favor it, influencing the ecosystem by setting standards for operational excellence and enabling firms to execute high-level strategies daily.[4][5][6]

Quick Take & Future Outlook

Integrated into Forrester, SiriusDecisions will likely deepen AI-enhanced analytics for B2B go-to-market (GTM) optimization, evolving tools like the Demand Waterfall into CX clouds for predictive insights.[6] Trends in data democratization, vertical AI applications, and global B2B expansion will shape its path, potentially amplifying Forrester's influence in underserved sectors. Its evolution from independent analyst to powerhouse product line underscores enduring value in bridging strategy and execution for sustained growth.
