Zac Auger

Chief Revenue Officer Postman

Last Reviewed: September 19, 2026

Executive Summary

Zac Auger is Chief Revenue Officer of Postman, the platform on which a large share of the world’s developers design, test, document and collaborate on APIs. He arrived from Square, where he had spent eight years and ended as Head of Growth, running sales, support and the go-to-market technology stack across an organisation of more than two thousand people. His route there was itself a sale: Square acquired Framed Data, the Y Combinator machine-learning startup where he worked, and he joined in 2016 with his team. Alongside the operating career he has run Upforth, an angel investing firm he started in 2015 to back Bay Area founders through product-market fit and their first institutional round. His public case for how revenue leadership should work is unfashionably simple — start from what creates value for the customer rather than what extracts it, and accept that this sometimes costs money in the short term.

Career Highlights

• Chief Revenue Officer of Postman, quoted on the record in that capacity in January 2026.
• Head of Growth at Square (Block) from 2016 to 2024, leading all Sales, Support and go-to-market technology.
• Led a global revenue and support organisation of more than 2,000 sales, account management and customer support staff at Square.
• Joined Square in 2016 with his team from Framed Data, a Y Combinator startup applying machine learning to customer retention and upsell.
• Earlier, the first sales hire at Quid, an early big-data company backed by Founders Fund.
• Started Upforth in 2015, a San Francisco Bay Area angel investing firm helping founders reach product-market fit and Series A financing.
• Drove Postman’s decision to lower the threshold at which customers can pay by invoice rather than credit card — more operational work for the company, less friction for growing customers.

Professional Journey

Auger’s career has run along the seam between data and selling. He began as the first sales hire at Quid, an early entrant in what was then called big data, backed by Founders Fund — the kind of role where there is no playbook, no territory and no quota history, and the job is to find out whether the product can be sold at all. He went from there to Framed Data, a Y Combinator company applying machine learning to customer retention and upsell: the same instinct, now pointed at predicting which customers would stay.

Square acquired that team in 2016 and Auger joined with it. He stayed eight years and ended as Head of Growth, with responsibility spanning sales, support and the go-to-market technology that connects them — a global organisation of more than two thousand people across sales, account management and customer support. The scope is worth noting, because it is unusual: putting support and sales under one leader treats the customer relationship as a single thing rather than two departments with different incentives, which is consistent with how he talks about the job.

In parallel, and in fact predating Square, he started Upforth in 2015 to invest as an angel in Bay Area founders, with a stated focus on the stretch between an idea and product-market fit — the period where a company’s first commercial motion either works or does not, which is precisely the problem he had been solving as an operator.

He moved to Postman as Chief Revenue Officer. Postman sells into an unusually self-selecting market: developers adopt it individually and organisations formalise that adoption later, which makes the revenue function less about origination and more about not getting in the way of something already happening. Auger’s stated philosophy fits that shape. “When I make decisions or set priorities, I start with what creates value for the customer, not what extracts it,” he told Built In in January 2026, citing Postman’s move to let more customers pay by invoice rather than card — additional operational burden for the company, removed friction for organisations wanting to grow on the platform. “Doing right by the customer sometimes costs a little more in the short term, but it builds trust that compounds over time.” On running the team itself he is similarly procedural: “I’ve found teams operate at the pace of their check-ins. When conversations happen weekly, priorities stay sharp, blockers surface quickly and progress compounds.”

Education

No educational record for Zac Auger could be established from any named source. A previously recorded B.A. from Hamline University traced only to third-party data-broker profiles and has been removed; notably, his own firm’s team page lists degrees for its other member and none for him. The field is left empty rather than restated without sourcing.
