SaaS products, MVP to exit
SaaS products tend to stall in one of three places: an MVP that takes a year, a launch that falls over when the first big customer signs, or a sale that drags on in technical due diligence. We have built through all three, and we build each stage with the next one in mind, without overbuilding the one you are in.
01In detail
What each stage needs
An MVP in weeks, not quarters
One core workflow done well, in front of paying users. Login, billing and an admin panel from day one, because you will need them by week three.
Multi-tenant from the start
Tenant isolation in the data model, so one customer can never see another’s records, and enterprise asks like SSO do not mean a rewrite.
Billing that matches the pricing page
Subscriptions, trials, seats and usage-based plans through Stripe or local gateways, with the awkward edge cases handled.
Scaling when it is real
Queues, caching, read replicas and autoscaling, added when the numbers call for them rather than because a conference talk did.
Numbers investors ask for
MRR, churn, activation and cohorts straight from the product database, not a spreadsheet someone updates on Fridays.
Ready for due diligence
Clean repositories, documented architecture, licence-checked dependencies and a security review. Buyers look for exactly this.
02Process
How it runs
We plan for the day you hire your own engineering team. Code, infrastructure and documentation are set up so they can take over without months of archaeology.
MVP
6 – 10 weeks
Agree the one problem the product solves, build it end to end, and launch to real users with billing switched on.
Fit
Weekly releases
Changes driven by what users actually do. Everything is instrumented, so decisions come from data rather than opinions.
Scale
When the numbers say so
Performance work, infrastructure as code, monitoring and on-call, so growth does not turn into outages.
Exit
2 – 3 months before a sale
Code and infrastructure audit, documentation, security review and a technical pack for the data room. We also help answer buyer questions during due diligence.

Security checks
Six security checks before every launch.
Before anything goes live, we test it the way an attacker would, then write down what we found and how we fixed it. The same six checks run on every project, from a one-page website to a government portal.
- 01
Scan for known weaknesses
We check your code, the libraries it uses and the server for weaknesses attackers already know how to exploit.
OWASP Top 10 · CVE database
- 02
Try to break in
Our engineers attack it the way a real attacker would: logins, permissions, file uploads, pages that should be hidden.
OWASP ASVS
- 03
Check every public link
Every public page and address is crawled for files, folders and test pages that should never have been online.
OWASP Top 10
- 04
Look for malware
The code, the server and anything users can upload are checked for malware and hidden backdoors.
Before every launch
- 05
Try to trick the AI
For AI agents, we try to make them leak data, ignore their instructions or use access they should not have.
OWASP Top 10 for LLM Applications
- 06
Write it all down
Every finding, how we fixed it and the re-test that proves it, in a report your auditors can read.
ISO/IEC 27001-aligned process
Our process follows ISO/IEC 27001 controls. Prospiral is not ISO certified. VAPT means vulnerability assessment and penetration testing: the first two checks above.
05Questions
Questions we get asked
Most MVPs we scope land in six to ten weeks. The trick is cutting scope hard, not typing faster.
Yes, that has its own service: AI-built MVP to production. We audit it, close the security holes and make it ready to scale, usually without a rewrite.
Yes. We start with a short review of the code, infrastructure and monthly costs, then fix whatever is most likely to hurt you first.
Buyers check that you own the code, that it is secure, that it runs without the founders, and that the numbers in your deck match the database. We prepare all four.
