Case Study: How a German Agency Doubled Revenue with Multi-Language Chatting

A mid-sized OnlyFans agency based in Berlin expanded from German-only chatting to 7 languages and increased monthly revenue by 2.1x in under 6 months. Here is how they did it, what went wrong along the way, and the specific numbers behind the growth.

TL;DR

A 4-person Berlin agency managing 3 OnlyFans models was stuck at roughly 18,000 EUR/month. After deploying ForgeFlow for real-time translation, they expanded into Spanish, French, Italian, Portuguese, Polish, and Dutch markets. Within 5 months, monthly revenue reached 38,000 EUR - a 2.1x increase - without hiring a single native-speaking chatter.

The Agency Before ForgeFlow

The agency (anonymized as "Agency M") was founded in late 2024 in Berlin. By mid-2025, they managed 3 creator accounts on OnlyFans with a team of 4 chatters, all native German speakers with strong English skills.

Their revenue breakdown at the starting point looked like this:

MetricValue
Monthly revenue (avg.)~18,200 EUR
Active models3
Chatters4
Languages servedGerman, English
International fan share~8% (English only)
Avg. response time4-6 minutes

The agency was profitable but plateauing. They had maximized their German-speaking audience and were leaving money on the table every time a fan wrote in Spanish, French, or Italian. Their chatters would either ignore these messages or respond in English, which rarely converted to paid content.

The core problem: Over 30% of incoming DMs were in languages the team could not handle. These messages had an average response rate of 12%, compared to 87% for German messages.

The Decision to Go Multi-Language

Agency M considered three options for handling foreign-language fans:

They chose ForgeFlow primarily because of the cost structure. At 207 EUR/month versus 10,000+ EUR/month for native hires, the risk was negligible. The 7-day free trial also helped - they could test it before committing.

Implementation and Rollout

Setup took less than a day. The agency owner installed ForgeFlow on all 4 chatters' Chrome browsers in the morning, ran a 30-minute training session, and had everyone chatting in multiple languages by the afternoon.

Results: Month by Month

The numbers below are aggregated across all 3 models managed by Agency M.

MonthRevenueInternational %Languages ActiveAvg Response Time
Baseline (pre-ForgeFlow)18,200 EUR8%25.1 min
Month 121,400 EUR18%65.4 min

Month 331,800 EUR40%74.8 min
Month 435,500 EUR44%74.6 min
Month 538,200 EUR47%74.5 min

Response time actually decreased over time. Chatters reported that ForgeFlow's inline workflow was faster than manually typing in German because the translation step handled grammar and spelling automatically.

Revenue Breakdown by Language

Not all languages contributed equally. Here is the incremental revenue attributed to each new language market by month 5:

LanguageMonthly Revenue Added% of Total Revenue
Spanish6,800 EUR17.8%
French5,200 EUR13.6%
Italian3,100 EUR8.1%
Portuguese2,400 EUR6.3%
Polish1,600 EUR4.2%
Dutch900 EUR2.4%

Spanish and French were the clear leaders. The agency owner noted that these markets had the largest untapped audience for their creators' content niches (fitness and lifestyle).

What Went Wrong

It was not all smooth. The agency encountered three notable issues during the transition:

Cost vs. Return

5-month financial summary

ItemCost / Revenue
ForgeFlow subscription (5 months, 3 models)-1,035 EUR
Additional revenue generated (cumulative, 5 months)+62,800 EUR
Net return+61,765 EUR
ROI5,967%

The tool paid for itself within the first 3 days of month 1. Even if the agency had only added Spanish, the return would have been substantial.
