An API is a standardized connection between separate software applications. It enables one program to request data or services without understanding the internal workings of another system. These defined rules allow diverse systems to interact smoothly, ensuring secure communication and functionality across different platforms.

An API is a set of rules that lets one piece of software ask another for information or actions. For example, a weather app may use an API to request today’s forecast from a weather service, then display the result for you.

I recommend using a hosted authentication provider rather than building your own system from scratch. For a two-person startup, the overhead of managing security patches and compliance standards often outweighs the initial savings, limiting your ability to focus on core product features. The hosted solution provides immediate reliability and expertise that is too specialized for early-stage teams to replicate effectively without hiring expensive specialists. However, the single strongest argument against this choice is the risk of vendor lock-in. If the provider experiences a catastrophic outage or suffers a security breach, your user access becomes instantly unusable unless you can rapidly migrate complex integration assets. This creates a technical debt where your growth is constrained by an external third party rather than your own business logic, potentially hindering long-term product control and data sovereignty.

Use a reputable hosted authentication provider. For a two-person startup, authentication is security-critical but rarely differentiating, and building it well requires ongoing work across password storage, account recovery, MFA, session management, abuse prevention, compliance, monitoring, and incident response. A provider lets you launch faster and reduces the chance that a subtle implementation flaw compromises users. Choose one with standards-based integrations and an export path to limit lock-in. The strongest argument against this recommendation is vendor dependency: pricing can rise sharply with user growth, and migrating authentication later can be difficult because password hashes, MFA credentials, sessions, and identity links may not transfer cleanly.

AI spending is hard to predict because usage, pricing, and implementation costs can all change quickly. Unlike traditional software, many AI services charge according to consumption: the number of questions asked, documents processed, images created, or computing resources used. A successful pilot can therefore become much more expensive when thousands of employees or customers adopt it. A second cause is uncertainty about which technology will be needed. Different AI models vary greatly in price, speed, and quality, while vendors frequently release new versions and revise commercial terms. Teams may also discover that a cheaper model is adequate for routine work but that sensitive or complex tasks require more costly systems. Third, the model itself is only part of the bill. Reliable AI often requires data preparation, system integration, security controls, testing, human review, monitoring, training, and legal or compliance work. These supporting costs are easy to underestimate, particularly when projects move from demonstration to production. Executives can improve control by funding AI in stages, with clear limits and decision points. Require each project to define expected usage, business value, accuracy needs, and total operating cost. Track spending by team and use case, set alerts and quotas, and review actual costs monthly. Negotiate vendor protections, avoid unnecessary dependence on one provider, and maintain contingency budgets for rapid growth, compliance changes, or unexpected technical work.
