Why I Built Promanda + ARCH Collective
Where marketing strategy meets precision, and ideas turn into impact
I’m Amanda Rabideau, founder of ARCH Collective and Promanda. For years, I led marketing and communications teams, then in 2019, I built an on-demand agency model with ARCH: fractional CMOs, strategists, and creatives who step in and deliver when it matters. Along the way, I noticed a pattern: teams spending too much time wrestling with words, trying to create on-brand messaging that truly connects and converts. That is the gap Promanda fills. It’s an AI messaging platform for agencies and marketing consultants that turns scattered inputs into ready-to-go marketing assets, following a structured system.
The problem I kept seeing
Great messaging is not written in a vacuum. It’s built (often painstakingly) through collaboration and (hopefully) guided by a well-defined strategy. Most teams start from a blank doc, juggle inputs, and then get stuck in revisions. Strategy lives in one place, draft copy in another, and stakeholder feedback everywhere else. Meanwhile, clients often want catchy copy right away, without realizing the path to get there is interactive and iterative —especially for freelancers —requiring structured inputs, shared alignment, and a few focused passes. The result is slow launches, watered-down messaging (think taglines, brand pillars, elevator pitches), and mental fatigue. I wanted a better way for marketers to lock the essentials first and generate a strategic framework they could defend to leaders and clients. If you’ve ever needed messaging framework software or a go-to-market messaging tool, you’ve felt this challenge.
Two paths became one
ARCH Collective is the human engine: fractional CMOs, strategists, and creatives who craft strategy, diagnose roadblocks, and execute. Promanda is the system: our guided messaging flow software helps marketers capture audience profiles, pain points, and outcomes, then crafts precise language. It’s a true zero-to-one messaging tool that turns guesswork into clarity. For consultants who need to package offerings, Promanda also offers white-label messaging tool options and a client portal for marketing agencies to keep briefs, versions, and approvals in one place. For freelance marketers, you can collect insights earlier, which become case studies and momentum to land your next client.
What this means for you

My goal is to give marketers the tools, structure, and support I always wanted on the inside: a way to move faster, think bigger, and tell compelling stories that win trust. That’s why I built this business: Promanda’s messaging platform offers fewer revision cycles, faster launches, and better results.
