My Test and Takes on HubSpot’s new GPT Deep Research integration

I tried HubSpot’s new GPT Deep Research integration this week — here’s what I found 👇

I’ve been curious how this would work in a real marketing workflow (and how it could benefit my clients), so last weekend, I ran tests in a sandbox version of my own HubSpot setup — side‑by‑side with GPT and Claude, to separate hype from reality.

What I Tested

Connected HubSpot → GPT for prospecting insights, predictive scoring, personalized follow‑ups, and dynamic campaign ideas.

What I Liked (and where I’m Stuck)

1. Real-Time Data Insights

Real‑time insights were 🤯 — surfaced micro‑segments and intent patterns we’d been blind to, making audience refinement almost effortless.

2. Automation that still needs a human hand

Sequences ran smoothly, but I kept tweaking copy/timing to avoid “robotic follow‑ups.”

💭 Which customer signals does GPT actually read well — and what still needs prompt tweaking to feel human?

3. Privacy + compliance is still the Elephant in the Room

Cool features, but I kept wondering.

💭 What guardrails keep data fully compliant?

4. Powerful… but not an exactly “plug and play” for everyone

The power is real but I think many marketers may still hit friction. They know the questions to ask, but not how to phrase them so GPT understands. 

💭 Will this evolve into a true no‑code tool, or keep staying ops‑heavy?

5. Dashboard + testing gaps

Strong MVP, but I miss native marketing dashboards to experiment before pushing live.

6. "Deep Research" mode only

Right now it only runs in "Deep Research" mode, which is great for depth, but not ideal when you just need quick questions or tweaks. 

My Overall Impression:

This could cut out so much those pains in “export → clean → then re‑import" and finally put GPT’s power inside a CRM marketers already know. But strong data governance and team readiness for prompt‑driven workflows is key before scaling.
