Product engineering for agencies
Product engineering, shipped under your brand.
Blanqo builds the web apps, integrations and AI features your clients ask for — fixed scope, fixed price, QA’d against a written spec before it ships. You keep the client, the credit and the margin.

The problem
Sound familiar?
-
You turned down a build last month because the team was full.
-
Your last freelancer went quiet halfway through a project.
-
A client wants an AI feature and nobody in-house has shipped one.
-
Every quote you give is a guess, and the guess is your margin.
What you get
Your clients see one team. Yours.
-
100% your brand
Your name on the repo, the handover and the invoice. We never appear client-side.
-
Written spec before a line of code
You approve the acceptance criteria up front.
-
Fixed scope, fixed price
Change orders, not surprises.
-
QA’d against the spec
Functional, cross-device, security basics, clean-clone deploy.
-
Say yes to the bigger brief.
Complex integrations, AI features, full products.
-
Limited builds per month
So every one gets a technical founder’s attention.
What we build
The work AI can’t one-shot.
Every build starts with a written spec and ends with QA against it. Here’s the range.
- Web & Mobile
Full-stack web platforms
Next.js and React up front, Node.js or Laravel behind it, built to be handed over rather than babysat.
- Web & Mobile
Cross-platform mobile apps
A single Flutter codebase shipping to iOS, Android and the web, plus Windows, macOS and Linux from the same codebase.
- AI & ML
AI assistants and RAG
Assistants that answer from your client’s own documents, with semantic retrieval, long-term memory and a source behind every reply.
- AI & ML
AI agents and tool use
Models that call your client’s APIs, chain steps and hand back a finished task, not a paragraph.
- Backend & Data
Integrations and webhooks
Payments, CRMs, messaging and the third-party APIs your client already pays for, wired in and documented.
- Platforms & Marketplaces
Marketplaces and multi-role platforms
Customer / vendor / operator flows, logistics and delivery.
- Backend & Data
Secure backends
Custom auth where it’s warranted, role-based access, row-level security and endpoints with tests behind them.
- Backend & Data
Real-time and collaborative apps
Live cursors, presence and instant updates over websockets.
- Specialty
Proposal and spec support
Technical write-ups your agency can put in front of its client, under your name.
- AI & ML
Multimodal AI
Image, voice and text combined into one pipeline.
- AI & ML
LLM-powered tooling
Generation, classification, assessment and grading systems.
- AI & ML
Research-grade NLP
Text classification and analysis with transformer models.
- AI & ML
AI tutors and assessment
Tutors that ask instead of tell, quizzes that adjust to the learner, generated rubrics and questions, similarity checks.
- AI & ML
Fraud and anomaly detection
ML classification on large transaction and event datasets.
- AI & ML
Voice interfaces
Speech in, speech out: transcription, reasoning and a natural-sounding reply in one loop.
- AI & ML
LLM failover and routing
Several model providers behind one interface, so a rate limit or an outage never reaches the user.
- AI & ML
Structured, deterministic AI output
Schema-checked responses and fixed scoring rules wherever a guess isn’t acceptable.
- Web & Mobile
Offline-first apps
Keep working with no connection, sync on reconnect.
- Web & Mobile
3D and interactive web
Three.js, WebGL and canvas work that runs in the browser with no plugin.
- Web & Mobile
Design systems and Figma-to-code
Your designer’s Figma turned into a component library the next build can reuse.
- Web & Mobile
Accessibility-first builds
Keyboard, screen-reader and contrast requirements written in as acceptance criteria when the project calls for it.
- Web & Mobile
Spec-to-handover delivery
From the first spec to the final handover: architecture, build, QA and release under one team.
- Platforms & Marketplaces
Learning platforms
Course delivery, progress tracking and game mechanics that keep learners coming back.
- Platforms & Marketplaces
Healthcare and wellness apps
Telemedicine, appointments and patient-facing flows, with compliance scoped per project.
- Platforms & Marketplaces
Cognitive and wellness apps
Assessment and screening flows with rule-based scoring, scoped per project.
- Platforms & Marketplaces
Vertical super-apps
Community and niche platforms built out properly: accounts, payments, content and admin in one product.
- Backend & Data
Data architecture
Schemas designed for the queries they’ll actually serve: normalized, indexed and cleanly migrated on Postgres, MySQL or Supabase.
- Backend & Data
Notifications and background jobs
Push, queues, scheduled triggers, so the product acts without a user in the loop.
- Backend & Data
Performance tuning
Slow pages and heavy queries fixed with the right index, cache or rewrite.
- Backend & Data
Security hardening
Rate limits, input sanitisation, secrets kept server-side and a security review before every launch.
- Backend & Data
Release pipelines and monitoring
CI/CD, separate dev, staging and production, and error monitoring from day one.
- Specialty
AR experiences
3D content that locks onto printed markers and physical products.
- Specialty
Narrative and visual-novel engines
Branching stories driven by their own scripting language, with animation and effects built in.
- Specialty
Game and interactive tooling
In-house engines, scripting layers and visual node editors.
- Specialty
Developer tools
Plugin frameworks, visual editors, internal tooling.
How it works
Five steps. No surprises between them.

Usually within a few days.
-

Code, credentials, docs. IP assigned to you.
Who’s behind it
Two founders. One signs off every build.
A technical founder writes every spec and signs off every build before it ships; a delivery lead runs the schedule.

- Delivery lead
- Runs the schedule and the milestone updates.
FAQ
Questions agencies ask.
We already have developers.
Good — we’re overflow and specialty capacity, not a replacement. We take the builds your team can’t fit this month, or the ones outside its stack.
How do I know the quality?
You approve written acceptance criteria before the deposit. QA runs against them, and you sign off before final payment.
Will you ever contact my client?
No. Non-solicitation is in the contract, and we never appear client-side by design.
What about timelines?
Confirmed in writing in the quote — not guessed on a call.
What do you build?
Web apps, mobile apps, AI features and full products — see What we build above. If it’s not there, send the brief anyway; we’ll tell you in one business day whether it’s a fit.
- React
- Next.js
- Node.js
- Laravel
- Flutter
- Supabase
- Postgres
- pgvector
- OpenAI/Groq-class LLM APIs
Who owns the code?
You do, on final payment. Every SOW includes an explicit IP assignment.
Have a build you can’t staff this month?
One business day reply. No pitch deck, no discovery call to get a number.
