For founders and product leaders

Senior engineers who can own the technical path.

We embed senior product engineers into SaaS, mobile, and AI teams to ship critical roadmap work, strengthen architecture, and leave the codebase more maintainable.

Why teams choose us

Why product teams trust us with important engineering work

The teams that hire us usually need stronger ownership, a faster path through delivery risk, and systems their internal team can still run six months later.

01

Senior ownership

Senior engineers stay close to scoping, implementation, review, and release decisions instead of handing work down a chain.

02

Faster execution

Direct engineer communication removes agency layers and keeps roadmap-critical work moving with less churn.

03

Maintainable systems

Architecture, QA, release discipline, and handoff stay inside the same workflow so your team inherits something usable.

Featured case study

SCAPITAL

Challenge

SCAPITAL needed a paperless lending platform with finance-grade security, real-time calculator logic, and partner-bank coordination without turning delivery into a black box.

What we owned

  • Full-stack architecture and FinTech-grade security implementation
  • Development of custom financial logic and real-time calculator engines
  • Banking partner API integration and data synchronization management
  • Cloud infrastructure setup for high availability and secure data storage

Fit

Who we work best with

The strongest engagements have urgency, room for senior ownership, and a team that cares what the codebase looks like after launch.

Best fit

Best fit

Teams that want senior leverage, direct communication, and delivery discipline.

  • Founder-led or product-led teams with real delivery urgency
  • SaaS, mobile, or AI products shipping actively
  • CTOs and founders who need senior leverage without adding management overhead
  • Teams that value ownership, collaboration, and quality

Not the right fit

Not the right fit

Teams looking only for cheap capacity or hands-off output tend to need a different model.

  • Lowest-cost staff augmentation only
  • Junior-only execution expectations
  • Delivery models with no collaboration or product context
  • Projects where nobody can own priorities, decisions, or handoff

Engagement models

Flexible engagements, one senior standard

The commercial structure can change. The delivery standard does not: senior engineers, direct communication, and clear technical ownership.

Engagement models

Dedicated engineering squad

$10K to $25K / month

Best for

Roadmap-heavy product teams that need senior engineers embedded into weekly delivery.

What's included

  • 2 to 4 senior engineers
  • Weekly demos and shared planning
  • Architecture ownership built in

Working model

Shared planning, direct engineer communication, and a weekly delivery rhythm.

Engagement models

End-to-end product build

$20K to $50K / project

Best for

New products, rebuilds, or major releases that need one team owning scope through launch.

What's included

  • Discovery through release
  • Design, backend, frontend, and QA alignment
  • Launch support and handover included

Working model

Structured phases from discovery to launch with the same senior team staying close to execution.

Engagement models

Architecture & scale retainer

$3K to $8K / month

Best for

Live products that need ongoing performance, delivery, and infrastructure support.

What's included

  • Performance and infrastructure improvements
  • Feature delivery on an ongoing cadence
  • Monitoring, code review, and stability work

Working model

Ongoing support for platform quality, roadmap work, and operational hardening after launch.

How we work

How we plug into your team

The process stays simple so scope, ownership, and delivery do not get lost in translation.

  1. 01

    Align

    We align on scope, constraints, ownership, and what success needs to look like.

  2. 02

    Embed

    We plug into your tools, team rituals, and communication channels instead of inventing a parallel process.

  3. 03

    Ship

    We ship in weekly increments with direct communication, review discipline, and clear progress signals.

  4. 04

    Handoff

    We leave behind code, context, and documentation your team can keep running without us.

Ownership and security

Ownership and security stay simple

Access, infrastructure, and delivery stay centered on your team so there is no confusion about who controls the stack.

This is the same operating standard we use on new builds and live products: private repos, scoped access, and delivery inside your stack instead of ours.

Full IP ownership

You own the code, design files, environments, and documentation from day one.

NDA-ready process

We can work under your NDA and keep access scoped to your private systems.

Repo stays in your org

Code is pushed to your GitHub or GitLab repositories instead of being locked inside ours.

Cloud stays in your accounts

We ship into your AWS or GCP setup so administrative control stays with your team.

Clear docs and transition

The handoff includes the context and documentation your internal team needs to keep moving.

FAQ

Questions teams ask before we work together

Short answers on staffing, ownership, communication, and how we handle delivery inside an existing product team.

If the question affects scope, ownership, security, or handoff, we prefer to cover it before work starts.

All engineers are full-time, in-house team members. We do not subcontract delivery.

That keeps quality, continuity, and architectural accountability in the same hands throughout the project.

Yes. You own the intellectual property from day one.

That includes code, design files, deployment access, and the documentation needed for clean handoff.

Senior engineers own the architecture, and every project includes peer review, release discipline, and documentation standards.

We optimize for a codebase your next internal team can understand and extend.

You communicate directly with the engineers building the product.

Typical engagement rhythms include shared planning tools, weekly demos, and day-to-day async communication in Slack or a similar channel.

Start timing depends on scope and current availability.

We usually clarify fit, scope, and timing early in the conversation so both sides know whether the engagement can start quickly or needs a short lead-in.

Major builds include a post-launch stabilization period.

After that, many clients continue on a retainer for ongoing feature delivery, performance work, and infrastructure support.

Yes. Many engagements work best alongside an internal founder, CTO, product team, or engineering lead.

We plug into your tools and rituals rather than creating a separate delivery layer around the work.

We can work within client security and documentation requirements, and we scope compliance-specific needs early.

If you have audit, access-review, or vendor-review requirements, it is best to surface them in the first conversation so the delivery setup matches them.

We usually plug in where there is strategic value, delivery pressure, or both.
