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.

An API is a set of rules that lets one piece of software request information or services from another. For example, a weather app can use an API to get a forecast from a weather service, rather than collecting the data itself.

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.

Use a reputable hosted authentication provider. For a two-person startup, it’s usually better to spend limited engineering time on the product than on securely implementing and maintaining login, password recovery, account protection, and security updates. The strongest argument against this choice is dependency: if the provider has an outage, raises prices, or makes migration difficult, access to your product and your costs may be outside your control. Before choosing one, check its reliability, pricing at your expected scale, and how easily you can export users and migrate.

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.

AI spending is difficult to forecast because costs depend on more than the price of a model. Demand, technology choices, and organizational behavior can all change quickly, often at the same time. First, usage is unpredictable. A successful assistant may attract far more requests than expected, and longer conversations or larger documents cost more to process. Set budgets and usage alerts, test demand before a broad rollout, and charge costs to the teams generating them. Second, prices and performance vary across providers and models. A powerful model may be unnecessarily expensive for routine tasks, while a cheaper one may require extra checking. Compare total cost and quality, use simpler models where appropriate, and retain the ability to switch suppliers. Third, model fees are only part of the bill. Preparing data, connecting systems, securing information, monitoring results, and training staff can exceed initial estimates. Fund these activities explicitly, with an owner accountable for the full cost. Finally, benefits are uncertain. Errors, regulation, and changing business needs can force rework or delay savings. Review spending against measurable outcomes regularly, run small pilots, and stop or redesign projects that do not deliver. Forecast a range rather than a single number, and keep a contingency reserve for unexpected expenses.
