From One Conversation to Software You Own
Stop paying per seat for tools you've outgrown. In four simple steps, we replace your SaaS subscriptions with custom software — built around how your team actually works.
Tell Us What to Replace
Start with a free 30-minute call. Walk us through the tools your team uses every day — and the ones costing you the most. We'll identify what to replace, what to keep, and how much you'll save. No jargon, no sales pitch.
You'll know exactly what we're building, how long it takes, and what it costs.
- List of SaaS tools to replace (with cost savings)
- Map of how your team works today
- Clear feature list — only what you actually need
- Fixed-price quote — no surprises
Preview Your Software
Within hours, you'll see a clickable preview of your new software — real screens, real workflows, your branding. Click through it, share it with your team, and tell us what to change. Nothing gets built until you say "go."
You see exactly what you're getting before a single dollar is spent on development.
- Clickable preview you can share with your team
- Your workflows mapped into real screens
- Your branding and colors applied
- Change requests before anything is built
We Build It
Our team combines AI-powered development with human expertise to build your software fast — without cutting corners. Every feature is tested, every workflow verified. Your existing data is migrated automatically so nothing gets lost.
Production-grade software built in days, not months — reviewed by senior engineers.
- Your custom software — fully working, not a prototype
- Works on desktop, tablet, and mobile
- Your existing data migrated over
- Connected to the tools you keep (email, calendar, payments)
Launch & Own It Forever
We walk your team through the finished product, make any final tweaks, and launch it live. You receive the complete source code — it's yours to keep, modify, and run on your own servers. No lock-in, no recurring license fees, ever.
You're live. You own everything. No vendor lock-in.
- Live demo with your team
- Final tweaks implemented same-day
- Deployed to your servers (or ours)
- Complete source code handed over
- Team onboarding — we train your staff
How We Deliver This Fast
Not magic — methodology. Here's why we can replace your SaaS stack in days, not months.
200+ Pre-Built Modules
We don't start from scratch. Your app is assembled from battle-tested building blocks — scheduling, billing, CRM, approvals — then customized to your workflow.
AI + Human Expertise
AI handles the repetitive coding. Senior engineers handle the decisions that matter — security, architecture, and making sure everything actually works.
150+ Apps Delivered
We've replaced SaaS stacks for law firms, clinics, agencies, and startups. We know the patterns — so your build goes faster.
Your Data Moves With You
Switching tools is only scary if you lose data. We migrate everything from your existing SaaS — verified, validated, and kept safe throughout.
Export from your SaaS
We pull your records from Salesforce, HubSpot, Jira, Zendesk, QuickBooks — any tool with an API or CSV export. You keep the original data as your backup.
Transform to your new schema
Records are mapped to your custom data model. We reconcile fields, clean up inconsistencies, and preserve relationships (contacts ↔ deals ↔ notes).
Verify integrity
Row counts match. Key fields validated. Nothing dropped, nothing silently changed. We run checks before and after import so you trust what you see.
Import into your app
Data loads into your new system. You can test alongside your existing tools until you're ready to cut over. Original SaaS stays accessible until you say otherwise.
Security & Compliance, Built In
Every AltStack build ships with enterprise-grade security defaults — not an add-on, not an afterthought. Your infrastructure, your rules.
Encryption Everywhere
AES-256 at rest, TLS 1.3 in transit. All secrets stored in managed vaults. Zero plaintext anywhere in the stack.
Role-Based Access
Granular permissions per user, team, or resource. Every action logged. Admin approvals for sensitive operations.
SOC 2-Aligned Architecture
Standard on every build. Access reviews, audit logs, change management, and incident response baked into delivery.
HIPAA-Ready for Healthcare
BAA-covered hosting, PHI encryption, audit trails, and access controls for any build touching patient data.
Your Infrastructure
Deploy on your AWS, Azure, GCP, or Vercel account. Data never sits on shared multi-tenant servers. You own the security posture.
Full Audit Logs
Every user action, data change, and admin event logged with timestamps. Exportable for compliance reviews or internal audits.
The 7-Day Delivery Guarantee
If we don't deliver a working application within 7 days of the approved design, you receive a full refund. No questions asked. We've maintained a 98.7% on-time delivery rate across 150+ builds.
- Clock starts when you approve the design preview
- Delivery means a fully working app, not a mockup
- Revisions happen after delivery and are included in your plan
- Large enterprise builds may have custom timelines
Questions About the Process
Transparent answers for teams evaluating custom software vs. SaaS.
The 7-day window starts when you approve the interactive mockup (Step 2) and ends when we deploy a production-ready application to a staging environment. This is a fully functional app, not a wireframe or prototype. Revisions happen after delivery and are included in your tier. For context, our median delivery time is actually 5 days.
Three factors. First, our component library contains 200+ pre-built, production-tested modules for common business workflows: CRM, scheduling, billing, document management, etc. Second, our engineers use AI coding tools that generate, test, and refine code 3–5x faster than manual development. Third, our team has built 150+ similar apps, so we know the patterns. We're not inventing solutions. We're assembling proven components and customizing them to your workflow.
Minor scope adjustments during the build are expected and free. If you realize mid-build that you need an additional workflow or integration, we'll accommodate it as long as it doesn't double the project scope. For significant scope changes, we'll pause, re-scope, and provide an updated quote before continuing. We never surprise you with additional charges.
Absolutely. If you have a design system, brand guidelines, or Figma files, send them over and we'll implement your exact design. If you don't, our team creates a clean, modern UI based on your branding (logo, colors, fonts). Either way, the final product looks and feels like your software, not a generic template.
We export your data from existing tools via their APIs or CSV exports, transform it to fit your new data model, and import it into your custom application. We've migrated data from Salesforce, HubSpot, Zendesk, Jira, Asana, Airtable, and dozens of other tools. The migration is included in your build cost. It's not an add-on. We verify data integrity post-migration and keep your original data intact as a backup.
Bug fixes are covered free of charge during your entire post-launch support window (30 days for Starter, 90 days for Growth, 12 months for Enterprise). "Bug" means any behavior that doesn't match the approved specification. After the support window, bugs can be fixed under an optional maintenance plan or by your own developers using the source code.
Yes. Most clients replace some tools but keep others. We build native integrations with whatever you want to keep: Google Workspace, Slack, QuickBooks, Stripe, Twilio, your email provider, calendar system, or any tool with an API. These integrations are built into your application, not bolted on with Zapier or middleware.
Every deliverable includes clean, typed TypeScript code with inline documentation, a README covering architecture decisions, database schema documentation, API endpoint reference, and deployment instructions. Any mid-level developer familiar with React and Node.js can pick up the codebase. We build for long-term maintainability, not just speed of delivery.
Our standard stack is Next.js, React, TypeScript, PostgreSQL, and Tailwind CSS, deployed on Vercel or AWS. This stack is chosen for type safety, developer availability, and performance. If you have strong preferences (e.g., Vue, Python/Django, MongoDB), we can accommodate them, though delivery timelines may extend beyond 7 days for non-standard stacks.
Every build undergoes a security audit covering OWASP Top 10 vulnerabilities, dependency scanning, SQL injection prevention, XSS and CSRF protection, and encrypted data storage. We implement role-based access controls, session management, and audit logging by default. Enterprise tier includes SOC 2-aligned architecture and compliance documentation for regulated industries.
