Fractional AI Product Lead

Turn customer problems into products.

Before you’re ready for a full-time Senior Product hire.

I join early-stage AI teams when founders and CTOs can’t keep owning Product on the side.

You probably don’t need another Product Manager.You need someone to take Product off the founders’ plate.

Product has become too important to stay a side job.

Customers pull in different directions, and engineers wait on decisions only the founders can make.

A full-time Product Lead might still be premature.

That’s the gap I fill.

Companies usually bring me in when…

  • Founders still make most Product decisions.
  • Engineers keep asking what matters most this sprint.
  • Every big customer wants their own version of the product.
  • You’ll hire a PM eventually, but decisions can’t wait until then.
  • You have more opportunities than capacity to build them.

Ways we can work together

What do you need to move forward?

Ongoing leadership

Fractional AI Product Lead

Product still sits with the founders, and you need someone to own it.

Clear direction. A team that knows what to build next.

  • Customer discovery and prioritisation
  • Strategy, roadmap and AI prototypes
  • Delivery, alignment and learning

Usually two days a week. I can also support your existing PM.

You always work with me directly. I work with a maximum of 2–3 companies at a time.

From customer conversation to shipped product.

I work inside your team and own the result with you.

  1. Discover

    What is actually worth solving?

    I talk to customers and check what they say against your data and goals.

    Your team getsA clear problemWho it affects. Why it matters.
  2. Decide

    Where should we focus next?

    We pick one Product bet and agree what success looks like.

    Your team getsA focused directionPriorities, scope and success metrics.
  3. Prototype

    Does the idea hold up with users?

    I build a rough AI prototype and put the riskiest assumption in front of users.

    Your team getsEvidence to act onBuild, refine or stop before investing more.
  4. Ship

    Did we make things better?

    I ship with your engineers and let results shape what comes next.

    Your team getsA release we learn fromMeasured outcomes and the next decision.

Short loops, together. Engineers are in the room from the first customer call, and we change course when the evidence says so.

See it in practice: from trust barriers to an AI review experience

Prototype, test with customers, refine. Then commit to delivery.
Engineers take part from the first customer conversation, and through delivery.

I use AI to put an idea in front of real customers in days, before anyone commits weeks of engineering time.

I don’t just manage teams building AI products. I build with AI too.

That way engineers spend their time on ideas that have already earned it.

Selected Product work

Three problems, and the decision that moved each one.

CandidlyEnterprise requests & scale

From one customer’s request to a reusable platform.

A large customer asked for a custom integration before renewing. Building it only for them meant one more special case to maintain.

The Product decisionA year of requests showed that six of our ten largest customers wanted the same thing, so we built three reusable building blocks any of them could plug into.

PwCAI adoption & trust

Turning a stalled AI feature into a tool auditors actually used.

Auditors couldn’t easily check the changes the AI suggested, and each stakeholder wanted a different redesign.

The Product decisionFirst find out why auditors didn’t trust it. Then show the AI’s changes apart from their own edits, and ship only what fixed those trust issues.

Making a marketplace work for more of its suppliers.

Buyers were searching plenty, yet a third of paying suppliers never heard from one, and those suppliers renewed at under half the usual rate.

The Product decisionLook at how buyer contacts were spread across suppliers instead of the average. Then match on what buyers really filter by, and show good suppliers who were being missed.

Hey — I’m Javi.

Javier Navero giving a talk

Senior Product Manager in AI products, with six years in international tech companies.

I like being close to customers, and I prototype before asking engineers to build anything.

I also founded The Impostor PM, a community helping Product people cut through the noise, build confidence, and turn AI and emerging ways of working into practical skills they can actually use.

Some things I believe
  • Doing beats knowing. You understand something much better once you’ve built it, broken it and fixed it.
  • Simple is usually harder (and better). Adding complexity is easy. Knowing what to take out is the hard part.
  • Freedom comes from responsibility. I earn ownership over my time and decisions by being someone people can trust to deliver.
  • Who you work with matters as much as what you work on. I’d rather build something small with good people.
  • Share what you learn. Knowledge is worth more when it’s passed around.
  • Everyone feels like an impostor sometimes, and that’s fine. The best people I know are still asking questions.

Let’s make sure your engineers build the right thing next.

Product becoming a bottleneck, but a senior hire feels premature? Let’s talk.

In 30 minutes we’ll see what’s stuck and what support makes sense. If I’m not the right fit, I’ll tell you.
