Scaling Engineering Culture Without Breaking It – Martín Sagastume
Get Matched in 48 Hours →Martín Sagastume advises engineering leaders on preserving the culture, operating habits, and team cohesion that make engineering organizations productive as they scale from 10 to 50+ engineers. He works with companies in the 12-to-18-month window following a Series B or Series C raise, when headcount is growing fastest and the cultural fractures that will drive attrition three years later are forming silently.
How engineering culture breaks – and why it's invisible until it's expensive
Engineering culture does not break during a hiring surge. It breaks in the 6–12 months after a hiring surge, when the informal norms and operating habits that made a small team effective have been diluted by new members who never learned them and are not being deliberately taught. The earliest signal is not attrition – it is a qualitative shift in how engineers talk about the company in 1:1s, a decline in voluntary knowledge-sharing, and a gradual increase in coordination overhead that shows up as missed sprint commitments before it shows up as departures. By the time the attrition signal is visible, the cultural damage is 18 months old.
The operating habits that define engineering culture at scale
Engineering culture at scale is not a values statement on the wall. It is the set of operating habits that every engineer practices consistently: how architectural decisions are made and documented, how code review is conducted and what standards it enforces, how incidents are handled and learned from, how new engineers are onboarded and evaluated, and how disagreements between engineers are resolved. These habits were informal and self-reinforcing at 12 people. At 40 people they need to be explicitly designed, documented, and actively maintained – otherwise the team will develop conflicting micro-cultures across squads that generate coordination friction and attrition risk.
Why culture advisory is different from management consulting
Engineering culture advisory is not a survey-and-report engagement. It is a diagnostic and design process that produces specific behavioral changes in how the engineering team operates: a new code review standard, a redesigned incident retrospective process, a squad formation principle that prevents team identity fractures, a new engineer onboarding program that transmits culture deliberately rather than by osmosis. The advisor's role is to identify which specific operating habits are at risk, design the interventions that protect them at the new scale, and work with the engineering leadership team to implement them in a way the team will actually adopt.
A STAR case from the Forward Share Ventures network
Situation: Series B engineering org scaling from 18 to 45 engineers over 14 months. Senior engineers beginning to leave, citing "it doesn't feel the same anymore." New hires not ramping to expected velocity. On-call fatigue rising. Architecture debates becoming political with squad splits forming along new-hire vs. tenure lines.
Result: 12-week engagement identified 3 cultural fracture points (ownership ambiguity, architecture decision process, on-call equity). Recommendations implemented by engineering leadership – annualized attrition dropped from 22% to 9%, new hire ramp time improved by 35%, and the architecture debate process was restructured to resolve disagreements within one sprint rather than escalating indefinitely.
Forward Share Ventures expert operators are selected from a verified STAR Portfolio™ of documented outcomes.
"Engineering culture doesn't break when teams grow – it breaks when the operating habits that worked at 12 people aren't adapted for 40, and no one is paying attention to the adaptation process. The signal always comes in retention before it comes in metrics. By the time it shows up in metrics, you're repairing damage that took two years to accumulate."

Frequently Asked Questions
How do I request an introduction to this expert operator?
Submit a brief through the match form at Forward Share Network. The team reviews your situation, confirms the expert operator's availability, and arranges a 20-minute introductory call – typically within 48 hours of your submission. No commitment is required before the intro call.
What engagement formats are available?
Three main structures: a structured advisory seat (one 60-minute session per month plus async availability), a scoped consulting project (30, 60, or 90 days with defined deliverables), or a strategic advisory retainer for ongoing functional partnership. The right format depends on your situation and timeline.
How much time does a typical engagement require?
Advisory engagements run roughly 2–3 hours per month per company, including the structured session and async exchanges. Scoped projects are more intensive for the duration – scope and time commitment are defined at kickoff. Most expert operators carry 2–4 active engagements simultaneously.
Are there placement fees or exclusivity arrangements?
No placement fees. Forward Share Network operates on an engagement model, not a transactional staffing model. Expert operators are not exclusive to any company – they bring the perspective of working across multiple situations simultaneously, which is a core part of the value.
What if my situation changes mid-engagement?
Engagements are structured with defined check-in milestones – typically at 30-day intervals. If your situation shifts, scope can be renegotiated at the next milestone. For scoped projects, the team can also configure a scope amendment before the halfway point if circumstances change materially.
