Datasets curated in Argilla or LabelBox; evals in Weights & Biases or MLflow. Fine-tuning is one of the most over-promised AI services. A senior engineer will tell you 70% of the time, prompt engineering + RAG beats fine-tuning at 5% the cost.

Marketing Agencies Industry Challenges We Solve
We understand the unique demands of the digital marketing and creative agency industry and build solutions that address them head-on. With a market size of $550B global digital advertising market, $170B US agency services, the marketing agencies sector demands technology partners who truly understand the industry.
1
Client Reporting & Attribution
Agencies juggle data from Google Ads, Meta, analytics, CRMs, and multiple client accounts. Creating unified reports that demonstrate ROI and attribute conversions across channels is time-consuming and often inaccurate without proper automation. For LLM fine-tuning engagements, addressing this at the architecture level from day one keeps it from compounding later.
2
Scaling Operations Without Headcount
Growing an agency typically means hiring more people, which compresses margins. Automating repetitive tasks — reporting, content scheduling, lead routing, campaign setup — is essential for profitable scaling. For LLM fine-tuning engagements, addressing this at the architecture level from day one keeps it from compounding later.
3
AI Disruption & Service Evolution
AI tools are changing what clients expect. Agencies need to evolve from manual execution to AI-augmented strategy and implementation, offering AI-powered content, AI ad optimization, and intelligent automation as core services. For LLM fine-tuning engagements, addressing this at the architecture level from day one keeps it from compounding later.
4
Client Portal & Communication Gaps
Client communication often happens across email, Slack, calls, and spreadsheets. Agencies need unified client portals for project visibility, approval workflows, and real-time reporting that reduce "where are we?" questions. For LLM fine-tuning engagements, addressing this at the architecture level from day one keeps it from compounding later.

Compliance Testing
Compliance is tested, not assumed. We run automated checks for marketing agencies regulatory requirements at every CI/CD stage — so compliance issues are caught before code reaches production.

Post-launch, we monitor for compliance drift with automated alerts on access patterns, data flows, and configuration changes. Quarterly compliance reviews are included in our maintenance agreements.
