An API is a set of simple, pre-defined rules that lets separate software apps share data and work together automatically, without you needing to manually move information between different tools.

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.

For your two-person startup, use a hosted user authentication provider rather than building your own. Auth requires ongoing security patching, compliance checks, MFA support, and breach mitigation that would eat weeks of your limited engineering time better spent building the unique core value of your product. The single strongest counterargument is that hosted providers carry meaningful long-term lock-in: pricing can jump sharply as you scale, and migrating auth later requires risky, user-facing credential resets that can drive noticeable churn if not executed perfectly.

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.

Your company’s AI spending is far harder to forecast than traditional software costs for three key, interconnected reasons that rarely come up with legacy tooling. First, most AI work relies on iterative experimentation, where early pilot results often require unplanned investments in custom training data, fine-tuning work, or even full project scrappage if outputs fail to hit required performance bars, with no way to lock in costs at project kickoff. Second, operational overhead scales dynamically rather than being fixed: inference costs are tied directly to usage volume, so unplanned cross-team adoption of a tool originally budgeted for one department can drive 2-3x projected monthly spend in weeks, with no static per-seat rate that holds steady as use cases expand. Third, fast shifting regulatory and vendor landscapes introduce unplanned costs overnight, from new data residency rules forcing migrations to more expensive regional model instances to unexpected vendor price hikes for features teams have already come to rely on. To address this, implement weekly lightweight usage dashboards that flag overspend triggers early, tie AI project funding to staged performance milestones instead of lump sum allocations, and require teams to submit documented usage guardrails before rolling out any new AI tool broadly, while leaving a small contingency buffer.

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.
