Lawrence Weetman

Senior Product Manager

Technical Platforms, APIs & B2B SaaS

I'm a product leader driven to solve complex, system-level problems. My software engineering insight gives me a deep understanding of developer experience and technical trade-offs, which I use to build 'force multiplier' platforms that unlock new capabilities and accelerate growth.

My focus is on mission-driven, B2B companies where I can help scale the product function and mentor colleagues.

Case Studies: the proof

Real-world examples of how I've solved complex, system-level problems and delivered measurable business impact.

0-to-1 Platform

Moody's Partner Programme

Context

Moody's KYC platform relied on 25+ third-party data integrations. Each one took 3–6 months for Moody's engineers to build and the maintenance of this many integrations resulted in constant firefighting. This throttled sales, frustrated clients, disempowered partners, and drained engineering capacity.

Solution

I led the 0-to-1 strategy and delivery of a self-serve Partner Programme: a standardised API, developer portal, sandbox, and beta programme with startup partners to prove the model before scaling to enterprises.

Impact

Transformed a bottleneck into a strategic asset. Integration time dropped to 4 weeks, with partners able to build their own integrations without engineering support. The platform also enabled 5 innovative new Moody's data products to launch with faster time-to-market and positioned our product as the key internal delivery channel for a "land-and-expand" growth strategy.

Mission-Critical System

Ocado's Robotic Warehouse API

Context

Ocado's stratospheric valuation gains assumed global expansion, which hinged on integrating new robotic warehouses with the new Ocado Smart Platform for clients like Casino Groupe, Sobeys, and Kroger. If we failed to deliver as agreed due to last-minute bugs, the company's reputation and valuation would be at risk. The margin for error was zero.

Solution

I took charge of a creative MVP strategy: connect a real robotic grid to our internal "staff shop", creating a live, zero-client-risk testbed. This allowed us to validate the entire end-to-end system with real orders and real hardware months before any client launch.

Impact

By launch day, the integration wasn't a risk... it was proven. Ocado's robotic warehouse tech went live to client sites with a very high degree of confidence, protecting the international programme and de-risking hundreds of millions in market value.

Internal Force Multiplier

Secondmind's ML Platform

Context

Secondmind's competitive edge was a team of around 20 elite ML researchers. But they were throttled by unscalable on-premise hardware, with researchers queueing to take turns to run experiments. A breakthrough idea on Tuesday might not be testable until the weekend, and a 12-hour job failing at hour 11 meant a full day of lost progress.

Solution

I treated the researchers as internal customers and led the creation of a cloud-based experimentation platform with parallel execution, automated failure recovery, cost controls, and self-service interfaces - freeing them from manual scheduling and technical bottlenecks.

Impact

The platform unlocked a 10x increase in research throughput, eliminated the experiment queue, improved reliability, and reclaimed researchers' time from having to agree and schedule experiments with one another. We transformed the company's R&D bottleneck into a strategic asset that multiplied the impact of our most valuable talent.

Three Companies, Three Transformations

I've lived through the hardest chapters in a company's story - hyper-growth chaos, post-acquisition culture shock, and start-up survival mode. Here's what I learned.

Ocado Technology
HYPER-GROWTH

Ocado Technology

250 → 1,600 people | 1 → 7 offices | 56p → £30 share price

Scaling through chaos as a UK grocery business transformed into an international tech powerhouse.

Read more about this experience

I joined when we were 250 people crammed into one office in Hatfield. I left when we were 1,600+ across 7 countries. I didn't just have ring-side seats; I was in the ring as a UK grocery business transformed into an international tech powerhouse. I learned that scaling isn't just about more people - it's about new systems, new communication patterns, and knowing when your old playbook is obsolete.

START-UP PIVOT

Secondmind

118 → 55 people | Strategic pivot

Surviving strategic pivot and downsizing while building the plane mid-flight.

Read more about this experience

I joined Secondmind when there were a little over 110 people. Five weeks later, the pandemic hit and really came down hard on the kind of supply chain businesses that Secondmind was built to help. I lived through a strategic pivot, leadership change, and downsizing to 55 staff, all while trying to find a new Product-Market Fit. I learned that start-ups aren't romantic - they're brutal, high-stakes experiments where you have to build the plane while jumping out of it. But when you survive...? You've just earned a superpower: comfort with ambiguity.

Moody's
POST-ACQUISITION

Moody's Corporation

80 → 14,000 person org | 3.5 years post-acquisition

Navigating acquisition and culture integration while preserving startup agility.

Read more about this experience

I joined 80-person scale-up Passfort on a Monday. We got acquired by 14,000-person Moody's on Tuesday. I spent 3.5 years learning that M&A isn't a one-time event - it's a slow, messy process of aligning cultures, roadmaps, and incentives. The hardest part? Preserving what made the small company great while gaining the leverage of the big one. The second hardest part? Balancing the expectations we set as a start up with the hopes-and-dreams of the new owners.

"Lawrence brings so much thoughtfulness and problem-solving to product management. He's able to break down complex concepts and communicate the ideas to anyone, whilst keeping the user and customer at the centre of his thinking."

My Leadership Philosophy

How I build high-performing teams and create lasting impact beyond individual projects.

Data-Driven Team Health

Vague frustrations don't fix themselves. At Moody's, I introduced Spotify-style squad health checks that turned "things feel broken" into specific, actionable data. When the team flagged release processes as the biggest pain point, this directly translated to leadership buy-in for a dedicated DevX team... proving that measuring team health isn't soft, it's strategic.

Pragmatic Roadmapping

Rigid quarterly plans force you to break promises. At Moody's, I championed a switch from a cycle of disappointing clients with rigid quarterly plans to a storytelling Now/Next/Later roadmap that later gave us permission to pause feature work and spend two quarters rebuilding critical tech - work that would never have happened under a feature-factory model. Strategic agility means knowing when not shipping is the highest-value decision.

Scaling Team Knowledge

One-off knowledge transfer doesn't scale. Within my first month at Moody's, I redesigned onboarding from a single overwhelming doc into a 10-lesson hands-on journey. Three years later, it had been used by 250+ people - from new hires to sales to engineers - saving an estimated 2,500 hours of senior staff time in terms of giving demos and answering questions. Not only that, but it built a shared language and deeper understanding of both the product and our domain that made people more effective. Systems that teach compound forever.

Servant Leadership & Org-Focused Outcomes

We all cross the finish line together, or not at all. At Ocado, I spotted that my Order Management team was ahead of schedule, while the overstretched Routing & Geolocation team was blocking our first international client launch. This would have harmed the reputation Ocado's valuation was built on. I convinced stakeholders, including my own team, that pausing our roadmap and pivoting the entire team to help was the best way fotward. We pulled the critical path forward by 2+ months, and the story became a company-wide case study for prioritising mission over metrics.

Empathy Through Immersion

Specs don't build empathy; lived experience does. At Ocado, I joined drivers on "buddy routes" to understand what about the job was causing 50% of drivers to quit within the first 12 weeks. Watching them wrestle with confusing delivery devices designed for the wrong workflow made the issue visceral. The insight didn't come from data - it came from feeling their frustration firsthand. We fixed the software, built tech that enabled new training routes, and cut that initial driver churn in half. I never trusted a spec doc quite the same again.

Creative MVP Strategies

You can't beta-test a £300M robotic warehouse at a client's site. At Ocado, I needed to de-risk the first-ever integration between our platform and physical warehouses. The solution: connect a real robotic grid to our internal staff shop, creating a live testbed with zero client risk. Months before launch, we had end-to-end proof the system worked. Creative constraints demand creative MVPs, even when only the finished product will do. Connect everything you have together early and often to see where the gaps are, and you'll more easily see how to fill them.
