A 14-person B2B marketing agency serving SaaS clients. They were turning down work because production capacity was capped by senior writer time. After a Treetop engagement, output doubled and margins expanded meaningfully. Here is how.
Composite case study: a synthesis of patterns we have seen repeatedly across similar engagements. Specific names, numbers, and details are illustrative; the patterns and outcomes reflect real client results.
Company stage: 14-person B2B content marketing agency, ~$2.4M revenue, serving primarily SaaS clients.
Capacity constraint: 6 senior writers were the bottleneck. Each could produce ~6 substantial pieces per month.
Pain: Turning down ~30% of inbound work due to capacity. Margins compressed because senior writers were doing first-draft work.
Existing AI usage: Junior staff using ChatGPT informally; senior writers resistant ("AI content is not our voice").
Week 1-2: Per-client Claude Projects built with each client's voice guide, ICP, and top-performing content loaded. Six clients in the first wave.
Week 3-4: Workflow redesign: junior staff produces AI-assisted first drafts using the client Project; senior writer does editorial pass; output ships.
Week 5-6: Editorial standards trained. The team learned how to make AI drafts not sound like AI (see our editorial guide).
Week 7-12: Full agency rolled into the new workflow. Senior writer time shifts from drafting to editing and direction.
Output per senior writer: From ~6 pieces/month to ~13 pieces/month. Editorial time per piece dropped from 6 hours to 2 hours.
Junior staff productivity: Up 3-4x — they could now meaningfully contribute to senior-level content under editorial supervision.
Quality: Client NPS held steady through the transition (the editorial discipline was the key).
New work accepted: Stopped turning away inbound. Revenue grew 38% in 6 months without headcount additions.
Margin expansion: Gross margin moved from 28% to 41%. Senior writer time at higher leverage; junior time more productive.
Talent retention: Junior staff who had been bored doing low-leverage work were now contributing to senior-level outputs. Best junior writers stayed instead of leaving for in-house roles.
Client acquisition: The agency now actively markets "AI-native production with senior editorial standards" as differentiation.
Investment: $8,500 Implementation + $300/month Claude Team for 14 seats. Total first-year cost: ~$12,000. Net new revenue: ~$900K.
