When a large company acquires a startup, the natural tendency is to impose its standardized processes. Successful integration requires a balance: knowing which systems to standardize for leverage while allowing the acquired team to maintain its freewheeling, startup-style execution.

Amphenol runs as a federation of autonomous business units. This structure is key to its M&A success, as acquired companies retain their brand, culture, and customer intimacy. Sellers prefer Amphenol because they know their business won't be suffocated by a monolithic corporate hierarchy.

Despite owning multiple related businesses (e.g., in video), Bending Spoons deliberately avoids forcing synergies like cross-selling or bundling. They believe the value lost in organizational agility, ownership, and speed far outweighs the small potential revenue gains. This 'Procter & Gamble for tech' model allows each brand to operate with startup-like autonomy, preserving its unique value.

To innovate at scale, Harness treats each new product as a semi-independent entity. These "startups" have a founder-like PM, go through internal seed/Series A funding stages tied to revenue milestones (e.g., $1M ARR), and are responsible for their own initial founder-led sales.

The 'compound startup' model of building multiple products at once is only viable when integration is more valuable than best-of-breed features. It also requires a shared platform architecture that genuinely accelerates the development of each subsequent product.

Vercel created a separate business unit for its AI tool, V0, because it targets a different audience (PMs, designers) and needed to operate with extreme speed, unburdened by the decision-making processes of the larger 700-person parent company.

PostHog manages its 16+ product suite by assigning small, autonomous teams of roughly three engineers to each product. This "compound startup" approach allows them to go wide, competing with multiple point solutions while remaining flat and avoiding bureaucracy. The small team structure fosters ownership and rapid development.

In a multi-product company, horizontal teams naturally prioritize mature, high-impact businesses. Structuring teams vertically with P&L ownership for each product, even nascent ones, ensures dedicated focus and accountability, preventing smaller initiatives from being starved of resources.

For certain acquisitions like Poker, IFS deliberately avoids full integration to retain the target's agile, entrepreneurial culture. Instead, they use product connectors and provide access to parent company resources, allowing the startup to maintain its dynamism while leveraging scale.
