What we build

From greenfield platforms to legacy system support, we cover the full development lifecycle.

Strategy & Planning

Technical Scoping & PRD

We turn product ideas into clear requirements, specs, and architecture plans, so development starts with direction instead of a guess.

Founder & Early-Stage PoC

We work with founders to validate ideas (including AI-powered products), scope an MVP, and build toward product-market fit. Lean in the early days, ready to scale once you need it.

Build

SaaS & Web Development

Full-stack web applications, customer portals, multi-tenant SaaS platforms. Built to scale, whatever stack you’re on.

Cloud Application Development

Cloud-native applications built for performance and reliability, sized to grow as your business does.

API, Architecture & Backend

REST API design, database architecture, and performance tuning for production-grade systems, LLM and third-party AI integrations included.

Operations

Legacy System Support

Stabilization, security patching, and gradual modernization for platforms that can’t just be rebuilt from scratch.

Project Delivery & Execution

Project leadership, contractor management, and CI/CD setup to ensure consistent, on-time delivery.

How we work

Simple by design

No status-meeting theater, no hand-holding. Just a process built to keep projects moving.

01

Discovery

We learn your business, your users, and your constraints before a single line of code gets written.

02

Technical Direction

We define the architecture, stack, and roadmap. You approve the plan before we build.

03

Build & Deliver

Iterative development with regular check-ins. Working software, shipped on schedule.

04

Handoff & Support

Clean documentation, knowledge transfer, and ongoing support if you need it.

About

Built to be a partner, not a vendor

Helix DevWorks is a remote-first engineering partner for startups and established B2B companies, handling everything from early architecture decisions to what happens after a platform ships.

We adapt to your workflow

We’ll work inside your existing tools and processes, or bring our own stack if you’d rather start clean. Either way, changes only happen where they actually help.

You own the code

Everything we build belongs to you, full stop. Repos live under your account, or we deliver straight into your existing codebase. No lock-in.

Flexible engagement

Embed with your existing team, or let us run independently. Work alongside your developers, or hand us the whole thing. You decide.

Straightforward engagements

Most projects are scoped and priced upfront: no surprises, no runaway invoices.

Team

Founder-led, expert by design

Cyrille B. Delavenne, Founder, Helix DevWorks
Cyrille B. Delavenne
Founder & Engineering Lead

Engineering leader with 10+ years in B2B SaaS. The defining chapter: 8 years at one startup, starting as the only engineer with no hiring playbook and no management template. I replaced a failing outsourced team, built my own from scratch, developed those people into self-sufficient contributors, and grew into the CTO role as the technical face of the company.

My methods stay sharp because I’m still in the trenches: I’ve led engineering at a fast-growth legal AI company, solving the same class of problems your project faces. You get that real-world experience applied directly, not just a track record.

Assembled for your project

I keep the core lean and bring in vetted specialists matched to each engagement: real people hired for the exact roles a project needs, not a bench you're paying for between jobs. When the scope calls for it, they're dedicated full-time (right now, a five-engineer team on a live enterprise platform). I handle sourcing and onboarding myself, so you're not running a second hiring pipeline. Your team can plug into ours, or we run the whole thing independently.

FAQ

Common questions

We design, build, test, and maintain scalable web applications, SaaS platforms, and API-driven systems, from architecture through to production. We work as a development partner for startups and B2B companies that need clean code, solid architecture, and reliable delivery.

Startups and established B2B companies, from early-stage founders validating an MVP to growing businesses scaling an existing platform. Our clients are typically building SaaS products, internal tools, customer-facing portals, or API-driven systems.

Yes, regularly. Most of our founder work starts pre-PMF: tight scope, lean build, nothing spent that doesn't need to be. Once you find traction, we scale with you.

It depends on what you need. We take on fixed-scope projects (PoCs, integrations, greenfield builds), ongoing retainers, embedded team augmentation, and hourly consulting. We can operate as an independent unit or work directly alongside your existing team. Your call.

We're headquartered in Montréal, Quebec, Canada and are fully remote-first. We work primarily with companies in North America and Europe, and are open to clients anywhere in the world. In-person meetings are available on request in Greater Montréal.

Always. Everything we build belongs to you. We set up repos under your account or deliver directly into your existing codebase and infrastructure. There is no lock-in, ever. You can take the work and run with it at any point.

Yes. We build LLM integrations, AI-powered features, and products that lean on third-party AI APIs, whether you're validating a new concept or bolting intelligence onto something that already exists. We hold it to the same bar as everything else: no shortcuts because the acronym is trendy.
