"Every growth team needs a north star metric with stability for at least six months"

Airtable's W4MUA metric: at least 2 users working together in week 4, with a 5-15% hit rate
Airtable tracked four metrics simultaneously: W2A and W4A at user level, W4MUA and build rate at workspace level
Led growth at Airtable during its rapid scaling phase and previously worked on user growth at Facebook, giving her direct experience with both consumer and B2B activation metrics. Their core argument: Use team-level activation metrics for B2B products, not just individual user actions. For multi-player B2B products like Airtable, individual user activation is insufficient.
The evidence is specific: Airtable's W4MUA metric: at least 2 users working together in week 4, with a 5-15% hit rate. Furthermore, airtable tracked four metrics simultaneously: W2A and W4A at user level, W4MUA and build rate at workspace level. Airtable's growth org pivoted its north star from revenue to user growth, a strategic shift that cascaded through every team's metric.
In Lauryn Isford's own words: "Every growth team needs a north star metric. It's so important to have singular focus on what the business results are that you are working to drive in your team." (On the importance of singular focus for activation work.)

The pattern works across SaaS: Lenny found nearly 90% of freemium products also offer a trial of their pro plan
Airtable: Free tier with seat-based pricing creates viral workspace adoption; reverse trial showcases advanced features to new signups
Lauryn Isford led growth at Airtable and was previously a product growth lead at Facebook focused on user growth in emerging markets. Her experience spans both massive consumer platforms and horizontal B2B tools with self-serve models. Their core argument: Offer a reverse trial: give new users full premium access for a limited window, then drop them to freemium -- you get the best of both models.
The evidence is specific: Airtable: Free tier with seat-based pricing creates viral workspace adoption; reverse trial showcases advanced features to new signups. Furthermore, the pattern works across SaaS: Lenny found nearly 90% of freemium products also offer a trial of their pro plan.
In Lauryn Isford's own words: "Personally I'm in the camp of offering a reverse trial. Funky name, but what that means is offer a trial but also offer freemium. Do both." (Declaring her position on the freemium vs. trial debate.)

Airtable shifted from revenue to user growth as the organizational NSM, enabling teams to take a decade-long view on monetization
Led growth at both Facebook (at scale) and Airtable (PLG B2B), giving her rare dual perspective on consumer and enterprise metric strategy. Their core argument: Every growth team needs a north star metric with stability for at least six months, but be willing to change it when the business outgrows it.
The evidence is specific: Airtable shifted from revenue to user growth as the organizational NSM, enabling teams to take a decade-long view on monetization. Furthermore, airtable's activation team used 'team activation metric' -- teams of people activated on the product -- as their specific NSM. At Facebook, Isford saw how experimentation culture at scale can make teams over-dependent on A/B testing rather than product judgment.
In Lauryn Isford's own words: "Every growth team needs a north star metric. It's so important to have singular focus on what the business results are that you are working to drive in your team." (Advocating for singular metric focus for growth teams.)
