Go-to-market strategy before launch: the pre-revenue B2B SaaS guide

Short answer: before launch, your go-to-market has one job: prove who buys and why, with money rather than compliments. Interview one tight profile until the same pain repeats, sell paid pilots before the product is finished, and land your first 10 customers yourself. Channels, ads and a sales stack come after that proof, not before.

What go-to-market means before launch

Pre-launch go-to-market isn't a launch plan. It's the work that decides whether a launch lands: who buys, the problem they'll pay to fix, what they use today instead, and a price at least a few of them have already paid.

In Mazo's stage model this is pre-product-market fit, zero to 10 customers, and the goal is to validate who actually buys and why. David Skok calls it the search for product-market fit, and his warning is blunt: spending scale-phase money in a search phase is the classic fatal error.

Mazo's rule of thumb: before 10 paying customers, track three things: interviews completed with one profile, the pains that repeat, and willingness-to-pay signals — a pre-order, a paid pilot, a signed letter of intent. Traffic, followers and waitlist size are noise until those move.

Validate who buys and why

Cindy Alvarez's Lean Customer Development gives the rules for the interviews:

Then name the job. Des Traynor's question: what is your product hired to do, and what gets fired to make room for it? April Dunford's positioning process starts in the same place, with the alternatives customers would use without you, including "a spreadsheet" and "do nothing". If nothing gets fired, be careful: Christopher Lochhead's point is that "no competitors" usually means no budget line.

Mazo's rule of thumb: pick one profile narrow enough that you could list 50 of them by name. Interview five. If the same pain comes up in all five, build around it; if it doesn't, change the profile, not the questions. No workaround and no spend today usually means they're not your buyer.

Charge from day one

Madhavan Ramanujam's Monetizing Innovation says to have the price conversation during discovery, not at launch. Once you've heard the problem, ask three questions:

The spread between the answers is your price corridor. Then ask for real money, because a price someone says out loud is still future intent. Ramanujam's "undead" product — one nobody would pay for, kept alive on hope — is what you get when you build first and ask later.

Keep it simple. Lenny Rachitsky's heuristic is that a single plan is fine before product-market fit, and if nobody complains about your price, it's too low. Tell your first customers they keep their price when you raise it; grandfathering buys more goodwill than it costs.

Mazo's rule of thumb: never give the product away to validate it. A discount is fine; free is not. If someone who has the problem won't pay a small amount for a pilot, they're an interviewee, not a customer.

Design partners that pay

A design partner is an early customer who shapes the product in exchange for early access and a say in the roadmap. The ones worth having pay. Put these in writing before you start:

Sell the pilot like any other deal. Steli Efti's rules apply: qualify hard, ask for the close — "Do you want to move forward?" — and follow up until you get a yes or a no.

Mazo's rule of thumb: get at least three paying design partners from the same profile before you build past the core workflow. Three partners from three different profiles will ask you for three different products.

Waitlists that mean something (and vanity ones)

A waitlist sign-up is future intent, and Alvarez's rule is that people are polite about the future. A list of 1,000 emails tells you your launch post travelled. It doesn't tell you anyone will pay.

Vanity signalSignal that means something
Waitlist sizeHow many people on the list match your profile and took a call
Likes on a launch postReplies that describe the problem in their own words
"I'd definitely use this"A workaround or money they already spend on the problem
Beta sign-upsPaid pilots, pre-orders and signed letters of intent

To make a waitlist mean something, add friction that filters. Put one qualifying question on the form — role, and what they use today — plus Chris Walker's free-text "How did you hear about us?". Invite everyone who matches your profile to a call, and offer a pre-order or paid pilot to the ones who describe the pain unprompted.

Mazo's rule of thumb: judge a waitlist by conversion, not size. Count how many sign-ups matched your profile, how many took a call and how many paid. If the list grows and those three numbers don't, you're building an audience, not validating a business.

Your first 10 customers

Lenny Rachitsky observes that most successful B2B companies got their first 10 customers from the founders' own networks and manual outreach, not from a channel. So don't plan a channel. Plan a list, and a pitch buyers understand: compete inside a category they already know and name what you replace.

Mazo's rule of thumb: sell the first 10 yourself, to one profile, at a real price, and write down every objection. When the same objection comes up three times, fix the positioning or the product before you pitch customer number 11.

Worked example (fictional)

Renewly: a pre-launch tool that tracks software renewals for IT managers

Fictional company, round numbers, for illustration only

Month one. The founder interviews 20 people: startup founders, agency owners, school IT staff, finance leads. Every conversation is interesting and none of them agree. That's Alvarez's noise pattern.

Month two. The founder narrows to IT managers at 100–500-person companies and interviews five. All five describe the same moment: a tool auto-renewed for another year before anyone checked usage. Four track renewals in a spreadsheet; one pays a procurement consultant.

Pricing. The three price questions give a corridor of roughly €100 to €400 a month. The founder offers eight of them a three-month paid pilot at €150 a month, with a weekly call and a case study as the giveback. Three say yes.

The waitlist: a launch post brings in 600 sign-ups. 40 match the profile, 6 take a call, none pay yet. The founder builds for the three pilots and treats the waitlist as a list to work, not as proof.

FAQ

Should I charge customers before my SaaS is built?
Yes, through a paid pilot or pre-order from people who have the problem. Madhavan Ramanujam's advice is to have the price conversation during discovery, not at launch. A small payment tells you more than any number of people saying they'd use it.
How many customer interviews do I need before building?
Five with the same profile, following Cindy Alvarez's rule: if they surface the same pain, you have a signal. Fifteen interviews across scattered profiles are noise, so tighten the profile before you interview more people.
Is a big waitlist a good sign for a SaaS launch?
Only if it converts. Judge a waitlist by how many sign-ups match your profile, take a call and pay for a pilot or pre-order. Size alone shows that your launch post travelled, not that anyone will buy.
Should I run paid ads before launching my SaaS?
No. Paid ads capture demand that already exists, and almost nobody is searching for a product that isn't out yet. Before 10 customers, sell by hand to one profile and use founder-led content to create demand.
What is a design partner in B2B SaaS?
An early customer who helps shape the product in exchange for early access and a say in the roadmap. The useful ones pay, even at a discount, and agree a success test, a weekly call and an end date before the pilot starts.
