01b / strategy evolution
Hamburg's DocuTrust GmbH launched Fastwrite mid-2025 as a Word add-in for German students and grew it on TikTok student-influencer ads plus a trilingual SEO blog and a Rewardful referral loop. Stripe-verified revenue peaked at ~$24.8k in March 2026 and eased to ~$14.9k MRR by August — consistent with thesis-season cycles or TikTok fatigue. All-time revenue is consistent with product age; no window artifact here.
