Services - Asset Engineering
We build. You own. Fixed price. Certification-ready.
Aegryn designs digital assets — B2B SaaS, vertical AI, mobile application — at a fixed price defined before the first sprint. Every delivered asset comes with complete documentation making it certification-ready from delivery.
Not an agency. Not a studio.
The Aegryn difference.
Fixed price. No overruns.
The fixed fee is defined and signed at the end of Discovery — before the first commit. If scope changes, an amendment is signed before execution. No surprise invoicing.
You stay 100% owner
No dilution. No equity taken by Aegryn. The asset is 100% yours. Aegryn can act as a co-investor on request: that is your decision, not ours.
Certification-ready at delivery
Every delivered asset comes with complete technical documentation (architecture, API, security, IP) making it ready for independent certification by any third-party auditor.
What very few others offer
One price. One scope. No surprises.
| What agencies do | What Aegryn does | How we get there |
|---|---|---|
| Indicative quote, real invoice differs | Fixed fee defined at Discovery | Discovery 1–2 weeks included |
| Time & materials with no ceiling | Measurable milestones per sprint | Certifiable specification document |
| Overruns billed as extras | Scope overrun absorbed by Aegryn | Price locked before first commit |
| Delivery without documentation | Full technical documentation included | Amendment signed if scope changes |
| No guarantee on final value | Certification-ready asset at delivery | Formal sign-off at each milestone |
Why documentation changes everything
A certification-ready asset is structurally worth more.
Documented and defensible value
An asset delivered with complete documentation has a defensible valuation multiple for fundraising or a sale. Not an estimate — a verifiable basis.
Contractual protection at delivery
What you order is precisely what you receive. The technical documentation certifies the state of every dimension at delivery. No grey areas.
Transferable to any team
Clean architecture, documented technical debt, complete README. Your asset can be taken over, modified or audited by any developer or independent firm.
What we build
Three typologies. One standard of excellence.
Vertical SaaS solution
Business tools, management platforms, RegTech, LegalTech, FinTech - SaaS designed for precise markets with measurable ARR/NRR metrics from launch.
Native AI product
AI agents, sector automation, document analysis - built on models with proprietary data. The real certifiable moat of an AI asset.
Mobile application
iOS/Android for services, marketplaces or mobile-first business tools. Retention metrics (D1/D7/D30) as design criteria, not as after-the-fact indicators.
Tech Stack
The technologies we master.
Stack selected based on your functional requirements, expected scalability and Aegryn Grade certification eligibility.
Frontend & Web
Backend & API
Databases
Mobile
Infrastructure
Integrations
Stack selected project by project based on functional requirements, expected scalability and eligibility for Aegryn Grade certification.
Our process
From brief to closing. One point of contact.
Discovery & Fixed Fee
Definition of the value proposition, target market, stack and exit plan. Output: specification + signed fixed-price agreement. Duration: 1 to 2 weeks. Cost: included in the total fixed fee.
Architecture and Design
The asset is architected to CIFS criteria: documented code, registered IP, security by design, tracked metrics. The grade is the construction plan.
Design and Iterations
Sprint-based development with measurable milestones, code review and continuous documentation. Aegryn proprietary stack or client stack.
Launch and Traction
Deployment, first-user acquisition, ARR/NRR/churn metrics setup. Time to certifiable Grade A: 6 to 12 months.
Certification (and optional exit)
CIFS protocol submission if desired. Official grade issued if criteria are met. A transaction via Aegryn or confidential channel is only engaged on your decision. The asset may also be retained with maintenance.
On-demand maintenance
The asset lives. We keep it running.
After launch or after a partial sale, Aegryn offers maintenance at two levels.
Corrective maintenance
Bug fixes, incident resolution, security updates, CVE management, monitoring and alerts. SLA defined in contract.
Monthly retainer or on-demand tickets
Evolutionary maintenance
New features, refactoring, version upgrades, integrations, regulatory adaptation (GDPR, EU AI Act, NIS2). The asset remains certifiable at all times.
Monthly retainer or per-sprint deliverable
Aegryn maintenance ensures the asset retains or improves its grade at every cycle: the condition for an exit to remain possible at any time.
Fees
Fixed fee. No surprises.
Diagnostic (included)
1 to 2 weeks. Certifiable specification. Build price defined and signed. No commitment before fee agreement is signed.
Included in total fixed fee
Design (fixed fee)

Fixed fee defined at Discovery
Maintenance (subscription)
Monthly retainer or per deliverable. SLA defined in contract. Cancellable at any time with 30 days notice.
Monthly retainer defined in contract
Aegryn may act as a minority co-investor on select projects: equity in exchange for a reduction in build fees. Assessed on a case-by-case basis.
A sale is an option, never an obligation. If you ever wish to sell — early stage or at maturity — the asset is designed for it. Exit via Aegryn or confidential transaction is available if the grade permits.
