Growth Molecules is a specialized customer success advisory and technology services firm focused on helping B2B technology and SaaS companies protect and grow their recurring revenue. Founded in 2020 by Emilia D’Anzica, the company combines operator experience from former CCOs and customer success leaders with structured methodologies, playbooks, and workshops to turn customer success into a predictable revenue engine. Their core mission is to help businesses "get scientific" about customer retention using data-driven strategies, AI-enabled workflows, and best‑practice processes.
The firm offers a mix of strategic advisory, fractional leadership, and hands‑on execution services across the full customer lifecycle. This includes assessments and diagnostics across people, process, and systems; customer journey and lifecycle design; onboarding, adoption, renewal and expansion playbooks; investor and portfolio-company programs; and technology implementation and optimization for leading customer success platforms such as Gainsight, Totango, Planhat, ChurnZero, and Vitally. Growth Molecules also runs the Growth Molecules Success Academy, including an accredited program in partnership with the University of San Francisco, providing structured training paths for customer success, support, and leadership roles.
Over the last few years, Growth Molecules has built a strong market position in the customer success consulting ecosystem. The firm reports having served more than 300 B2B SaaS companies and has earned over 130 five‑star reviews and an 88 NPS, reflected in its 4.9/5 G2 rating across more than 100 reviews. Its client roster includes well-known technology brands such as Gainsight, Square, Modern Health, Aurora Solar, Invoca, GitLab, Cisco, Bitly, and others, supported by published case studies with companies like Iodine Software, MentorcliQ, Virtuous, Nitel (Comcast), Talroo, and Fable.
In 2025, Growth Molecules announced that it was joining forces with HLX to combine pre‑sales and revenue operations expertise with its post‑sale customer success capabilities, creating a full‑funnel growth engine for B2B technology companies. Separately, SBI Growth Advisory acquired Growth Molecules’ customer success training assets to expand SBI’s own training portfolio. Despite these integrations, Growth Molecules continues to operate as a focused advisory and implementation brand within this broader ecosystem, differentiated by its operator‑led team, CS platform implementation depth, and tight focus on revenue retention and expansion outcomes.
