Long, unpaid design partnerships often have vague goals and low customer engagement. Spend a few days observing a customer’s work, find a narrow painful task, and test a focused product for it. If one customer will pay, try selling that same solution to 10 similar customers before broadening it.
The Sales Playbook For Founders
Speaker
An unnamed Y Combinator speaker shares advice for founders on moving B2B buyers from early product exploration to recurring contracts.
Free trials and proofs of concept need a clear question, success metrics, and a defined value equation. For example, a customer service AI pilot could test whether the product resolves 20% of a sample of 1,000 queries, supporting a case for $200,000 in annual software against $1 million in savings. Use low-risk tests such as backtesting, side-by-side comparisons, or a small share of customer volume.
Paid pilots encourage customers to engage and reveal early whether they may buy the full product. Keep pilots short, agree on customer-side data and staffing, schedule frequent check-ins, and arrange a results meeting before starting. Track time to first value; spreadsheets or emailed data can be faster than a full integration.
A recurring contract with a 30- or 60-day opt-out period can avoid a second sales process after a pilot. The contract converts to ongoing revenue if the customer stays, though founders should clearly describe opt-out customers when reporting MRR or ARR to investors. After signing, invest in onboarding and customer success; one company had signed $4 million in contracts but implemented less than $2 million.
Start security certifications early, identify an internal champion, and map the economic buyer, technical approver, security gatekeeper, legal team, and users. Ask how the customer buys software, agree on a target closing date, and leave meetings with the next touchpoint scheduled. Be flexible on contract edits while avoiding terms that could transfer product IP or create unlimited liability.
Takeaways
- Use a few days of customer observation to identify a narrow, urgent problem.
- When a customer pays for a focused solution, test it with 10 similar customers before expanding the product.
- Define pilot success and willingness to pay before the pilot begins.
- Shorten time to first value with practical workarounds when integrations would delay a test.
- Map the buying group and schedule the next step before each meeting ends.
