367 vetted experts across 21 tools.
Custom builds
238Bespoke, code-first builds rather than an off-the-shelf platform. Chosen when requirements outgrow packaged tools and the work justifies engineering it directly.
OpenAI
136OpenAI's GPT models and API, the default foundation for a large share of production AI builds. A safe pick when you want a well-supported, general-purpose model.
Claude
71Anthropic's family of language models, favored for careful reasoning, long documents, and drafting. Providers build on it where accuracy and tone matter.
n8n
61An open-source, self-hostable automation platform. Experts reach for it when a workflow needs custom logic, private data handling, or code steps that hosted tools cannot run.
Zapier
49The most widely adopted no-code automation tool, connecting thousands of apps. Best for getting reliable, standard integrations live quickly across a business.
Make
48A visual automation builder for multi-step, branching workflows. A common choice when a process is too involved for simple triggers but does not warrant custom code.
AWS
38Amazon Web Services, including Bedrock for foundation models. The choice for teams that need cloud-native infrastructure, scale, and data residency control.
RAG
34Retrieval-augmented generation: grounding model answers in your own documents and data so responses stay current and cite their source. The backbone of most knowledge and support builds.
Airtable
22A spreadsheet-database hybrid that often becomes the operational backbone of an automation. Experts use it as the shared data layer behind agents and workflows.
HubSpot
20A CRM and marketing suite that anchors many go-to-market teams. Providers wire AI into its records, pipelines, and sequences to automate revenue operations.
LangChain
17The most widely used framework for composing LLM applications, from prompt chains to retrieval pipelines. A marker of a firm that builds against model APIs directly rather than wiring no-code tools.
Gemini
15Google's multimodal model family, strong on long context and tight integration with Google Workspace and Cloud. Chosen by teams already living in that ecosystem.
Salesforce
15The enterprise CRM standard. Engagements here tend to be larger and more governed, embedding AI into established sales, service, and data workflows.
Evals & guardrails
13Evaluation suites, guardrails, and observability that measure whether an AI system actually works and keep it from regressing. The sharpest marker separating AI-native engineering from automation resale.
MCP
11The Model Context Protocol, an open standard for connecting AI models to your tools and data through a common interface. A recent, telling signal of a firm building on the current agent stack.
Vector databases
11The databases (Pinecone, Weaviate, Qdrant, pgvector) that store embeddings and power retrieval at question time. Their presence signals a firm building real retrieval systems, not demos.
Power Platform
10Microsoft's low-code stack (Power Automate, Power Apps, Copilot). The natural fit for organizations standardized on Microsoft 365 and Azure.
GoHighLevel
9An all-in-one sales and marketing platform popular with agencies. Experts layer AI onto its CRM, funnels, and messaging to automate client acquisition.
LangGraph
8LangChain's framework for stateful, multi-step agent workflows with explicit control over branching, memory, and human checkpoints. Favored for production agents that need to be inspected and debugged.
CrewAI
6A framework for orchestrating multiple role-based agents that collaborate on a task. Chosen when a job splits cleanly into specialist agents rather than one monolithic prompt.
Voiceflow
4A design platform for conversational agents and voice assistants. Used to prototype and ship chat and phone experiences without building the flow engine from scratch.
