Platforms & stack.
Not every project uses all of this — most use a handful. The point is that tool choice is driven by the problem, not by being locked into a single vendor.
Models & agent frameworks. Claude (Anthropic), OpenAI, open-source models where they fit. Agent frameworks and MCP servers for structured multi-step work. Claude Code and Cursor for build and iteration.
Automation & orchestration. n8n, Make, Zapier, Pipedream. Choice depends on scale, who'll maintain it, and what needs to run on-prem vs. hosted.
CRM & communication. HubSpot, Pipedrive, Salesforce, GoHighLevel (GHL), Attio. Twilio, Vonage, and messaging APIs where the CRM's native comms aren't enough. Calendly, Cal.com, and custom booking where scheduling is load-bearing.
Data & reporting. Supabase, Postgres, BigQuery. Looker Studio, Metabase, Mode. Supermetrics and Funnel.io for ad-platform pipes. PostHog and Mixpanel for product analytics.
Frontend & internal tools. Next.js on Vercel, Retool and Tooljet for internal UIs, Framer and Webflow for marketing surfaces where appropriate.
Telephony & voice. Vapi, Retell, ElevenLabs, and the major telephony providers for voice-agent work when it's actually the right answer — which is rarer than most vendors suggest.
