A B2B SaaS company with 12 people including 4 in revenue. Proposals were eating senior time and slowing deal velocity. After a Treetop Implementation engagement, the proposal cycle compressed dramatically. Here is what happened.
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: 12 employees, ~$3M ARR, B2B SaaS selling to mid-market.
Proposal volume: ~10 proposals per month, $30K-$120K ACV each.
Pain: Each proposal took 6-8 hours of senior team time (CEO or VP Sales). Deals stalled while waiting for proposals. Sales velocity capped by writing capacity.
Existing AI usage: ChatGPT Plus for one or two people, used inconsistently.
Week 1: Operational ICP definition. Audit of existing proposal templates and last 10 winning proposals.
Week 2: Built a Proposal Claude Project loaded with: 10 winning proposals (anonymized), brand voice guide, pricing reference, standard scope language, common objection responses.
Week 3: System prompt iterated until proposals matched winning voice. Trained the team (CEO, VP Sales, 2 AEs) on the workflow.
Week 4: Shipped 4 real proposals using the new workflow. Refined based on what worked.
Old workflow: AE takes discovery notes → drafts 6-hour proposal → CEO/VP Sales reviews and rewrites → ships in 2-3 days.
New workflow: AE pastes discovery notes into Proposal Project → Claude drafts in 5 minutes → AE refines for 30 minutes → senior reviewer does 15-minute polish → ships same day.
Quality: Win rate stayed flat in months 1-2, then increased 8% in months 3-6 as the team's editorial muscle developed for prioritizing the highest-leverage sections.
Time savings: Roughly 50 hours/month of senior team time recovered.
Sales velocity: Average sales cycle compressed from 35 days to 24 days because proposals shipped within hours of qualified opportunity.
Capacity: Without adding headcount, the team supported 60% more outbound activity because proposal-writing was no longer the bottleneck.
Investment: $3,500 Implementation + $300/month Claude Team for 10 seats. Total first-year cost: ~$7,000. Estimated value recovered: $150,000+ in senior time freed.
