01TECHNICAL APPROACH

How we cross from PoC to production.

Method, principles, and architecture that sustain every Levver engagement. Applies to tailored consulting and to the evolution of our own products.

See Custom Projects See Vertical Products

02PRINCIPLES

Five rules that govern everything we build.

The technical version of the company's five values. These are decision criteria used in every engagement, from architecture to handoff.

Outcome before stack

The choice of model, framework, and infrastructure is subordinated to the desired outcome. No institutional preference for frontier models or for a specific architecture.

Senior engineer as owner

Every project has a senior Levver tech lead as the technical owner, present from briefing to handoff. No bulk staffing of junior people, no disguised outsourcing.

Customization over template

The client's actual workflow is the starting point. Frameworks and templates are means to get there, not the product we deliver.

Transparent engineering

Repository, architecture decisions, and metrics are visible to the client's internal team from day one. No black box, no permanent dependency on Levver.

Production-first

Every diagnostic ends with a defined production criterion. No project is considered delivered until the code is running in the client's environment.

03THE METHOD

Diagnostic. Build. Production and Handoff.

Every engagement, regardless of the commercial format, runs through the same three phases. The duration of each phase varies. The discipline doesn't.

PHASE 01

Diagnostic

1 to 2 weeks

Mapping the real pain, validating the technology hypothesis, and defining measurable success criteria.

·Initial architecture document
·Agreed target metrics
·Explicit production criterion
·Pre-budget and timeline

PHASE 02

Build

4 weeks to 6 months

System construction with weekly or biweekly cadence. Code review shared with the internal team. Progressive deploy from staging to controlled production and full production.

·Repository with reviewed code
·CI/CD pipelines
·Automated evaluation
·Documented milestone demos

PHASE 03

Production & Handoff

1 to 2 weeks

Metric observed in real production for at least two weeks. Operational documentation, runbook, and knowledge transfer sessions.

·Operations runbook
·Complete technical documentation
·Handoff sessions
·Optional post-handoff support (3 to 6 months)

04STACK

Frontier and open-source. No religion of stack.

We pick the right model for the right problem. The choice between frontier (Claude, GPT, Gemini) and open-source (Llama, Mistral, fine-tuned models) is made on technical and cost criteria, not on institutional preference.

Primary infrastructure on Google Cloud Platform. AWS on demand when the client is already established there. Vector databases chosen by workflow fit.

CAPABILITIES

·Retrieval-Augmented Generation (RAG)
·Supervised fine-tuning
·Multi-step agents and tool use
·Automated evaluation (LLM-as-judge, eval datasets)
·MLOps and observability
·Document ingestion and processing pipelines
·Backend in Python and TypeScript
·Frontend in Next.js and React
·Integration with legacy systems (ERP, CRM, helpdesk)
·Vector databases and semantic search

05GUARANTEES

Everything that sustains the system stays with you.

A Levver engagement isn't a subscription to a proprietary platform. It's transferable construction, with IP and operations entirely in the client's hands at the end of the project.

Code in the client's repository

All code produced lives in the client's repository from week one. No hosting in a Levver environment.

Intellectual property transferred

IP for what was built to order is transferred in full at the end of the project. No residual licensing, no royalties.

Operations runbook

Operational documentation ready for the internal team to run the system without depending on Levver.

Complete technical documentation

Architecture decisions, model choices, infrastructure configuration. Everything recorded for future review.

Optional post-handoff support

A 3 to 6 month support contract is available, not mandatory. We continue when it makes sense for the client.

06SECURITY

How we handle sensitive data.

Each client runs in an isolated instance. Encryption in transit and at rest is an architectural default, not an option. Audit logs for sensitive data access are available on request. Contractual commitment to zero training on client data.

Per-client isolation

No mixing of data between tenants. Each client in a dedicated namespace or instance.

Zero training on sensitive data

Information processed in any Levver project does not feed public or internal models. Contractual clause.

Audit log and traceability

Sensitive data access is logged. Available to the client on request. Sensitive operations are always traceable.

Legal basis before processing

We turn down engagements that depend on processing data without a clear legal basis. LGPD and GDPR compliance as an architectural standard.

07NEXT CONVERSATION

The best meeting is the first one.

Thirty minutes with one of the founders. A direct technical conversation. No deck, no committee. You walk away with a prioritized technology hypothesis and a sketched success criterion.
