Product Bottleneck Diagnostics · B2B SaaS
Find your product bottleneck before your team adds more work.
I help B2B SaaS product leaders diagnose what is slowing progress, whether AI has outpaced the product operating model, or product usage is not converting into activation, team adoption, expansion, or revenue.

The bottleneck usually hides upstream.
When progress stalls, the visible symptom is rarely the real constraint. AI workflow problems often look like tool problems. Product growth problems often look like onboarding or pricing problems. Team adoption problems often look like feature gaps.
The diagnostic work is to separate the visible symptom from the constraint actually slowing progress.
Which bottleneck sounds more familiar?
AI Workflow Bottleneck
AI has made prototyping, documentation, discovery, and execution faster, but decisions, quality checks, escalation points, and team rhythm have not caught up.

Users are active, but activation, team adoption, expansion, pricing, or revenue is not following.

Bring one product problem. We will map the visible symptom, identify the likely bottleneck, and decide whether the right next step is an AI Workflow Diagnostic, a Product Growth Diagnostic, or no engagement.
Selected outcomes
- Delivered reev's first customer-facing AI feature: a natural-language insights engine for fleet operators.

Operator background
10+ years across B2B SaaS product leadership, Toyota Production Systems, Zalando Innovation Lab, Shiftmove / Vimcar, Kaufland e-commerce, and reev.
Why me
My work sits at the intersection of product leadership, B2B SaaS, AI-assisted workflows, product-led growth, pricing, behavioral analytics, and operational systems.
The focus is not more advice, more tools, or broader PM support. The focus is diagnosing the real constraint before your team commits more roadmap, hiring, or GTM effort.

I don't think local models will win
Building AI agents taught me that the real moat is not the model itself, but ownership of the memory, context, and operating layer around it.

Your Next Growth Lever Is Already Inside Your Customers
In B2B SaaS, the next growth lever is often hiding inside the existing customer base, not in a new feature. Here is how to find it before adding more roadmap work.
Not sure which bottleneck you have?
Bring one product problem. We'll use the call to identify whether the issue is workflow, decision-making, activation, adoption, pricing, expansion, or something upstream.
