What is Affinity?

Affinity is wiring deal data into outside AI tools while rebuilding its core list views.

The tracked source is Affinity's blog index rather than a changelog, so most of what lands here is article chrome and case studies. Underneath that, two genuine product items are visible: Affinity Lists rebuilt for faster performance with advanced filtering, and an Affinity MCP Server in beta that connects deal data to AI tools including Claude, ChatGPT and Gemini. The surrounding material — Speedinvest tracking 500+ LP relationships through automatic capture, a year-in-review post, an executive appointment — is positioning around relationship intelligence rather than shipped change.

What is Streak?

Streak wires automations to email and call activity, turning Gmail CRM into an event-driven workflow engine.

Streak is deepening its Gmail-native CRM position by tying automations directly to email threads, calls, and meeting notes — any new activity in a pipeline box can now trigger an automation. The Claude connector (one-click MCP integration) and an expanded MCP server for creating/updating records complete a trifecta of LLM-adjacent features shipped over the past few months.

Affinity vs Streak: editorial side-by-side

Affinity logo0.0

Affinity is wiring deal data into outside AI tools while rebuilding its core list views.

◆ Current state

The tracked source is Affinity's blog index rather than a changelog, so most of what lands here is article chrome and case studies. Underneath that, two genuine product items are visible: Affinity Lists rebuilt for faster performance with advanced filtering, and an Affinity MCP Server in beta that connects deal data to AI tools including Claude, ChatGPT and Gemini. The surrounding material — Speedinvest tracking 500+ LP relationships through automatic capture, a year-in-review post, an executive appointment — is positioning around relationship intelligence rather than shipped change.

◆ Where it's heading

Affinity is pushing on two fronts that reinforce each other: making the CRM's own surfaces fast enough to live in, and making its relationship graph reachable from whatever AI tool a dealmaker already has open. The consistent claim across the entries is automatic capture — email and meeting data collected without manual entry — which is what makes both the network mapping and the agent access worth anything. The category framing is relationship intelligence, not CRM.

◆ Prediction

The MCP server is in beta and is the obvious next thing to move; watch for it to gain write access to pipeline records rather than read-only querying, since the existing material already describes updating a pipeline from an AI tool.

Streak logo6.3

Streak wires automations to email and call activity, turning Gmail CRM into an event-driven workflow engine.

◆ Current state

Streak is deepening its Gmail-native CRM position by tying automations directly to email threads, calls, and meeting notes — any new activity in a pipeline box can now trigger an automation. The Claude connector (one-click MCP integration) and an expanded MCP server for creating/updating records complete a trifecta of LLM-adjacent features shipped over the past few months.

◆ Where it's heading

Streak is moving from a passive data store (CRM you update manually) toward an active workflow layer (CRM that reacts to what happens in your Gmail). AI citations, the Claude connector, and expanded MCP capabilities collectively suggest Streak's differentiation will be depth of LLM integration for a Gmail-native context — not competing with Salesforce on breadth.

◆ Prediction

The next likely move is AI-generated pipeline updates triggered by email activity — automations that don't just fire when email activity happens, but read the email content and fill in deal fields based on what was discussed.
