Most design partnerships are a complete waste of time. In these arrangements, founders collaborate with an early customer to co-design a product, often to validate an initial idea or acquire specific industry knowledge .

Tom Blomfield, group partner of Y Combinator and co-founder of Monzo, argues that founders mistakenly cling to these unpaid engagements. His playbook focuses on accelerating past them to secure real, recurring revenue from the start.

Blomfield’s analysis identifies a flaw in early-stage B2B sales. Founders must replace the illusion of progress with tangible financial commitments. This requires a disciplined framework, a focused product strategy, and an understanding of customer psychology to avoid common traps.

A rapid progression to recurring revenue

Blomfield provides a framework for B2B founders to quickly advance through sales stages. The goal is to close contractually recurring revenue as soon as possible by progressing from unpaid engagements to paid contracts with opt-out clauses.

This progression includes distinct stages:

• Unpaid design partnerships serve as an initial stage for product discovery. These often become unproductive due to poor definition and low customer engagement. Founders frequently get stuck here.
• Free trials or pilots are a necessary step when lacking social proof. These must be tightly scoped with clear success metrics to prove value and avoid becoming indefinite.
• Paid pilots introduce a financial commitment. This ensures the customer is serious and engaged. The cost should be low enough to bypass lengthy procurement processes.
• Recurring contracts with an opt-out represent the most effective approach. The customer signs a full annual or monthly contract. It includes a 30 or 60-day money-back guarantee, converting automatically if the customer is satisfied.

The goal is to progress through the sales sequence as rapidly as possible.
Blomfield states, “the goal for most early stage companies is to progress through this sequence as rapidly as possible so that you’re able to close new ARR every week and grow your company. And really 90% of the time, the vast vast majority of the time, founders get stuck in the very early stages.”

The ‘pro move’ secures recurring revenue from a single sales process.
He explains, “this is typically a monthly or annually recurring contract with a 30 or 60-day money back guarantee or opt-out period at the very start. But by default, if the customer does nothing and is happy with your product, it’s going to turn into a full recurring contract after that opt-out period with no additional sales process needed. That’s the pro move. It’s like magic.”

This process eliminates the need for a second sales cycle.
Blomfield notes the downside of a standard paid pilot, “you still need to go and negotiate the full contract afterwards. It’s like a whole second sales process just when you thought you had a customer who was ready to buy. And this can be very, very frustrating.”

Winning with a narrow wedge, not a broad platform

This rapid sales progression is impossible without a product customers will pay for. Founders often try to build a sprawling platform too early, so Blomfield pushes for a “narrow wedge” strategy instead. This approach focuses on a single, acute customer pain point.

Founders should solve one problem exceptionally well.
Blomfield advises, “the goal of all of this is to identify a really narrow burning problem, and you’d be able to go away and build a narrow wedge product in as little as 48 hours and bring it back to the customer and ask them to try it, see if it solves their problem.”

Overbuilding is a common mistake for early-stage companies.
He argues, “what many founders do which is a mistake is to try and overbuild a really broad platform… at this stage of your company because you just don’t have the resources. You can waste a lot of time without any real signal that the customer wants what you’re building.”
