Most enterprise asks land in one of these. We will tell you honestly if your work fits, and what to do instead if it does not. [01 · WEB ### Web applications Auth, roles, data, workflows. Typed end to end. Long-lived, maintainable, owned by your team. Read more](https://www.kensink.com/services/web-application-development/) [02 · SAAS ### SaaS products Multi-tenancy, billing, RBAC built in from day one. The foundation that lets feature work ship fast.

Read more](https://www.kensink.com/services/internal-tools-dashboards/) [04 · LLM ### Enterprise LLM SSO, RBAC, audit trails, PII redaction at the proxy. Vendor-neutral so your CISO is not locked to one model. Read more](https://www.kensink.com/llm/enterprise/) \[WHY ENTERPRISE TEAMS PICK US\] ## Four promises in writing. Stated up front because they are easy to verify after the build. These are commitments, not aspirations. 01 ### Senior engineers, no staff augmentation Every engagement is led by people who have shipped this category before. We are a lab, not a body shop. No interns, no offshore proxy. 02 ### Fixed price per phase, written scope Every phase has a written scope and a fixed number. Sprint or multi-phase program, the rule is the same: smallest valuable thing first, runbook for everything else. You can plan around the milestones and the numbers. 03 ### Direct integration, no framework lock-in We integrate against the model and the data the same way we integrate against Postgres: typed contracts, eval-gated, observable. No LangChain in the path you have to maintain. 04 ### Full source ownership at handoff Your team gets the code, the test suite, the eval pipeline, and the runbook. We are not retained. The build does not depend on us being in the room. \[COMPLIANCE + RESIDENCY\] ### We build for review, not against it. The proxy, the audit pipeline, and the prompt log are scoped to your requirements at week one. The build passes legal and security review because it was designed for the second meeting, not just the first demo. SOC 2 friendly HIPAA friendly ISO 27001 friendly GDPR · CCPA Data residency US / EU Your IDP · your VPC \[METHODOLOGY · K-FRAMEWORK\] ## Integrated through the K-Framework. Every model we integrate runs through the same operating system. Three pillars, sixteen layers, one Compound Growth Loop. The methodology that keeps AI work from rotting after the first ship. [Read the K-Framework](https://www.kensink.com/k-framework) 01 ### Foundations Direct API integration with the model. No LangChain, no orchestration vendor, no agent framework built on quicksand. Typed contracts, the same way we wire up Postgres. 02 ### Amplification An eval suite built from your real tasks gates every prompt and model change. Quality is measured before it ships, not vibed in a demo. 03 ### Judgment Governance, audit, and oversight wired in from day one. Who called what, with which prompt version, at what cost. Your auditors get answers, not screenshots. \[OBSERVABILITY\] ## Observability your team can read. A model in production without observability is roulette. We instrument every integration so engineering and finance can see the same numbers, and so a regression at 3am surfaces before a customer opens a ticket. Instrumented ### Cost per call Tokens in, tokens out, dollars spent. Sliced by feature, tenant, and route. Budgets enforced where it matters. Instrumented ### Latency p50 / p95 / p99 Real distributions, not averages. We know which routes are slow, and why. Instrumented ### Eval pass rates The same eval suite that gates a release runs continuously in production. A regression on real traffic surfaces fast. Instrumented ### Prompt + completion logs PII scrubbed at the proxy, shipped to your SIEM. Retention controls match your compliance window. Dashboards your team owns, not ours. At handoff you get the queries, the alerts, and the runbook. We are not in the path to read your metrics. \[HOW EACH PHASE RUNS\] ## Per phase, four chapters. Each phase ships on the same rhythm. Programs are sequenced phases of this shape, each with its own written scope and fixed price. WK 01 ### Scope and contract Two senior engineers in a room with the people who will use the build. We name the smallest shippable thing and write it down. The eval bar is set the same week. WK 02 - 06 ### Build on tested foundations Postgres, types, CI, and observability from the first commit. Eval pipelines run on every PR. Weekly demos to the buyer plus a live staging URL. WK 07 ### Eval before launch An eval suite over your real inputs. We block ship on regressions, not vibe checks. Audit log of every model call, every prompt change. WK 08 ### Handoff with ownership Production deploy, your team holds the keys, a runbook printed and reviewed in person, 90-day warranty in writing. \[ WHAT YOU GET \] ### What the engagement leaves behind. Per phase Fixed price, written scope 100% Source ownership at every milestone Eval-gated Tested before it ships 90 days Post-launch warranty \[COMMON QUESTIONS\] ## Things the buyer side usually wants in writing. What sectors do you work in? B2B SaaS, financial services, healthcare, legal, marketplaces, and manufacturing. The constant is regulated or high-stakes data and a team that wants to own the build after we leave. Who owns the code, the prompts, and the evals? Your team, from week one. The repository is yours, the eval pipeline is yours, and the runbook is printed and handed over at week eight. No licensing tail, no hosted dependency on us. What about data residency and compliance? We build inside your VPC and your IDP, with the proxy and audit pipeline scoped to your retention and residency requirements. We have shipped engagements with SOC 2, HIPAA, and ISO-aligned architectures. How long does a typical enterprise program run? Two to four phases is common, sequenced over six to twelve months. Each phase has its own written scope and fixed price. No open-ended retainers. The reason: it keeps incentives aligned and forces clarity at every milestone about what is being built and why. Do you take equity? No. Cash, fixed price, written scope. It keeps the conversation honest. SENIOR ENGINEERS · APPLIED K ## Bring the brief. We will bring the build. A 15-minute intro is the cheapest way to find out if we are the right lab. No deck, no pre-call form, no follow-up sequence.
