About Mammoth-dev
We started Mammoth-dev in 2024 because we kept watching small firms (CPAs, advisors, agencies) get squeezed: too small for Accenture or Deloitte to bother with, too busy to wire up AI themselves, too smart to settle for ChatGPT Teams alone.
Who we serve
5-person firms in regulated industries. CPAs, tax preparers, bookkeepers, RIAs, insurance agencies, M&A advisors, small law firms. We run AI for 32+ firms as of 2026.
What makes us different
- Managed, not DIY. You hire us; we run the AI. You don't learn prompt engineering.
- Multi-model. We pick the best model per task — Claude for writing, GPT-4o for code, Gemini for research, Llama for batch jobs. Swap when better ones ship.
- Real integrations. 40+ apps wired up — HubSpot, QuickBooks, Redtail, Agency Zoom, you name it. AI that takes action, not just chats.
- Small-firm pricing. $1,500/mo gets you what enterprise AI consultancies charge $15,000/mo for.
Our principles
- No lock-in. Month-to-month, export everything if you leave.
- No training on your data. Contractual with every model provider.
- No long meetings. 15-minute intro, no slide deck, no NDA required.
- No upsells. Tiered pricing, all features included at each tier.
