From first idea to global scale.
19 services across 5 phases of a startup's software lifecycle. Whatever stage you're at, we meet you there.
1
Built for your world,
not ours.
We learn your regulations, your users, your market: then build software that fits.
By Vertical
AI Startups
RAG pipelines that hallucinate less than 1%. Eval infrastructure that catches regressions before users do. AI products built for production, not demos.
Fintech Startups
PCI-DSS, bank API integrations, fraud detection. Compliant financial software that ships on time.
Healthtech Startups
HIPAA violations cost up to $1.9M per incident. We architect compliance in from day one so audits are paperwork, not fire drills.
E-commerce & Retail
Shopify hits limits. Headless commerce does not. Sub-2-second page loads and checkout flows optimized for conversion.
B2B SaaS
Multi-tenancy, SSO, audit logs, usage-based billing. The enterprise features that close larger deals.
Edtech Startups
Enrollment season spikes your traffic 400%. Your platform needs to handle it without going down.
Proptech Startups
MLS licensing, sub-300ms property search, multi-party transaction workflows. Real estate software that works like real estate actually works.
Legaltech Startups
Attorney-client privilege shapes every architecture decision. Contract automation and case management built for how law actually works.
Logistics & Supply Chain
Real-time fleet tracking, route optimization, offline driver apps. Logistics software that keeps moving when connectivity does not.
Consumer Apps
Day-7 retention is the metric that matters. Onboarding, notifications, and social features built to keep users coming back.

Your background
shapes the build.
First-time or repeat, technical or not — we adapt our process, communication, and delivery to match who you are.
By Founder Type
Non-Technical Founder
You have the domain expertise. We make the technology decisions and explain every one of them in plain English.
First-Time Founder
You do not know what you do not know. We have built 50+ products. We know what goes wrong and we will tell you before it does.
Solo Founder
You are wearing every hat. We become your entire engineering department so you can focus on customers and growth.
Repeat Founder
You have been burned by an agency before. You know what clean code looks like. We match your standards.
Student Startup
Your demo day is in 10 weeks. Your budget is not infinite. We scope to your deadline and your budget, not the other way around.
Corporate Innovator
Your IT security review takes three months. Legacy integration is required. We deliver startup speed within enterprise constraints.
Female-Led Startup
Consistent pricing. Direct communication. Engineers who treat your technical judgment as valid.
African Startup
M-Pesa, Paystack, offline-first apps, USSD fallbacks. Software built for how African markets actually work.
Diaspora Founder
Multi-currency, cross-border payments, two sets of compliance requirements. We handle the complexity of building across markets.
Social Enterprise
Maximum impact per dollar spent on technology. WCAG accessibility, grant-compatible budgets, measurable outcomes.
4
Right-sized for
where you are.
Pre-revenue and post-Series A need completely different things. We match the engineering approach to your current stage.
By Stage
Pre-Idea Exploration
You have a hunch, not a spec. We turn rough concepts into validated product directions in two weeks.
Validation Stage
Test your riskiest assumptions before writing production code. Two weeks of experiments beats six months of building the wrong thing.
MVP Development
Ship in 4-8 weeks. Fixed price. Senior engineers. Your MVP becomes your product, so it needs to be built like one.
Early Traction
You have users. Now find out why they stay, why they leave, and what to build next.
Seed Stage
Seed money is not infinite. Fixed-price sprints and senior engineers mean maximum output per dollar.
Growth Stage
Your DB queries took 50ms at 1,000 users and take 4 seconds at 100,000. That is an architecture problem, not a query problem.
Scale-Up
Your monolith has 200,000 lines of code and 30 engineers stepping on each other. Time to decompose, carefully.
5
We've solved your
problem before.
Every blocker has a playbook. Find yours and skip the trial-and-error phase entirely.
By Challenge
Need an MVP Fast
Fixed-price proposal in 48 hours. Delivery in 4-8 weeks. No scope creep. Ship and learn.
Outgrowing Current Tech
Your engineers are afraid to deploy on Fridays. Your DB is slow and getting slower. We find the real problem and fix it.
Agency Rescue
Your previous agency left a mess. No tests, no docs, no handoff. We assess honestly and recover practically.
Preparing for Funding
Technical due diligence is now standard. We harden your security, document your architecture, and prepare the answers investors ask for.
Adding AI Features
Adding AI is not a sprint task. We define the use case, build the infrastructure, and measure quality in production.
Crushing Tech Debt
New engineers take three months to get productive. Every estimate is wrong. On-call is up. We fix the foundation so shipping feels fast again.
Post-Pivot Rebuild
Half your codebase is solving the wrong problem. We find which half is worth keeping and rebuild the rest in 8-12 weeks.
No In-House Tech Team
You need a full engineering team but cannot hire one yet. We fill the gap completely until you are ready.
Launching in Africa
Your product was built for US users. Bandwidth assumptions, payment methods, and device types all differ. We adapt it properly.
From our engineering team.
Practical guides, deep-dives, and playbooks from the people building real products.
No hourly billing.
No surprises.
No excuses.
Most agencies bill by the hour: which means the longer your project takes, the more they earn. We flipped that. You get a fixed price before we write a single line of code. If we go over, that's on us. Not you.
Payment milestones
Fixed Price
The quote is the price. Period.
Senior Engineers
The team you meet builds your product. No handoffs.
Weeks, Not Months
Most projects ship in 4–8 weeks.
You Own Everything
Code, designs, IP: yours at each paid milestone.
