Forgo building custom AI tools for common problems. Instead, purchase 90% of your AI stack from specialized vendors. Reserve your in-house engineering resources for the critical 10% of tasks that are unique to your business and for which no adequate third-party solution exists.

When deciding to build or buy, the key factor is strategic importance. Never cede control of technology that is core to your unique value proposition to a vendor. Reserve outsourcing for necessary but commoditized functions that don't differentiate you in the market.
The key for enterprises isn't integrating general AI like ChatGPT but creating "proprietary intelligence." This involves fine-tuning smaller, custom models on their unique internal data and workflows, creating a competitive moat that off-the-shelf solutions cannot replicate.
Early-stage startups should resist applying AI everywhere. Instead, they should focus on one high-impact area where processes already work. AI is most effective as an amplifier for a solid foundation, not as a shortcut or a fix for fundamental strategic problems. Start small with integrated tools.
While it's tempting to build custom AI sales agents, the rapid pace of innovation means any internal solution will likely become obsolete in months. Unless you are a company like Vercel with dedicated engineers passionate about the problem, it's far better to buy an off-the-shelf tool.
Before engaging external partners, decide your tech strategy. 'Build' in-house for a core competitive advantage. 'Buy' off-the-shelf enterprise solutions for broad utility. 'Borrow' expertise from agencies for specialized projects where you want to upskill your team.
The opportunity cost of building custom internal AI can be massive. By the time a multi-million dollar project is complete, off-the-shelf tools like ChatGPT are often far more capable, dynamic, and cost-effective, rendering the custom solution outdated on arrival.
The true enterprise value of AI lies not in consuming third-party models, but in building internal capabilities to diffuse intelligence throughout the organization. This means creating proprietary "AI factories" rather than just using external tools and admiring others' success.
Avoid paralysis of choice in the crowded AI tool market. Instead of chasing trends, identify the single most inefficient process in your marketing organization—in budget, time, or headcount—and apply a targeted, best-of-breed AI solution to solve that specific problem first.
Instead of broadly implementing AI, use the Theory of Constraints to identify the one process limiting your entire company's throughput. Target this single bottleneck—whether in support, sales, or delivery—with focused AI automation to achieve the highest possible leverage and unlock system-wide growth.
Large companies integrate AI through three primary methods: buying third-party vendor solutions (e.g., Harvey for legal), building custom internal tools to improve efficiency, or embedding AI directly into their customer-facing products. Understanding these pathways is critical for any B2B AI startup's go-to-market strategy.
