21b Consulting

What 21b Consulting does

21b Consulting was a Cleveland-based, privately-held B2B growth consultancy founded in 2024 by Noelle Hatfield. The firm operated as a HubSpot Solutions Partner, delivering professional consulting services to mid-market B2B companies that had adopted HubSpot but were struggling to realize full value from the platform. Its service scope spanned strategy development, technology implementation, portal audits, and team adoption support, with an explicit emphasis on aligning people, process, and technology rather than selling software licenses.

The firm's go-to-market was consultative and sales-led: mid-market prospects were engaged through discovery calls and growth consultations, supported by content marketing assets including a blog, ABM Swipefile, and HubSpot help resources. Pricing was quote-based and not publicly disclosed, with revenue generated entirely through professional services engagements rather than productized SaaS or recurring subscriptions. 21b served a single horizontal segment — mid-market B2B HubSpot users with unmet growth goals — and employed between 1 and 10 people.

In April 2026, 21b Consulting was acquired by Greenfire Strategy, a Cleveland-based B2B growth consultancy and HubSpot Platinum Partner operated by Graziani Multimedia. The acquisition consolidated two HubSpot partner teams under one roof, expanding the combined entity's capabilities to include brand strategy, content, demand generation, and revenue operations. Client continuity was preserved, with Noelle Hatfield joining the combined organization. As a result, 21b ceased to operate as an independent entity and now exists as part of the Greenfire Strategy portfolio.
