The Modernization Playbook
A practical guide to replatforming critical digital products without disrupting the business.
Executive summary
Many organisations are running business-critical platforms on foundations that were built for a different era.
Legacy codebases, outdated frameworks, fragmented systems, security risk, and slow release cycles quietly drain enterprise velocity. Teams spend too much time keeping old platforms alive, having to maintain too many different technologies, and not enough time building what comes next.
Paloma helps companies modernize and consolidate these platforms safely.
We bring a specialised modernization system, combining proprietary tooling, AI-assisted codebase analysis, proven delivery patterns, and experience from rebuilding platforms used by millions of people.
This playbook distills what we’ve learned:
Paloma Digital is a 100-person venture studio and digital consultancy. We’ve built and replatformed products at scale—from Afterpay to MoneyGram’s global remittance platform.
Scale
Proven at replatforming business critical apps with tens of millions of users
Expertise
Specialists in AI-driven modernizations and AI-driven development
Trust
Trusted by enterprises where speed, reliability, and scale matter most
One of our apps:
25M+ active users, 4.9/5 stars on iOS and Android
Legacy platforms quietly drain velocity
What starts as a technical compromise becomes a commercial constraint: more technologies to maintain, harder hiring, rising security risk, slower delivery, and less confidence to pursue ambitious product ideas.

The Paloma Modernization System
Paloma helps companies modernize platforms through a repeatable, AI-native process refined across large-scale product rebuilds.
We combine proprietary tooling, expert engineering, automated testing, and proven release patterns to move from legacy constraints to modern foundations without putting the business at risk.
This is not a traditional rebuild. It is a productised modernization system designed to reduce uncertainty at every stage.
01
Understand the real system
We analyse the existing codebase to map features, dependencies, domains, APIs, risks, and behaviour from the system itself.
02
Prove the path before committing
We turn that analysis into a practical modernization plan, validating the highest-risk areas before major delivery begins.
03
Modernize for parity first
We recreate what works today on a stronger foundation before introducing major product change, making the new platform easier to test, release, and trust.
04
Release safely into production
We use automated tests, observability tooling, feature flags, rollback plans, and staged release patterns to reduce production risk.
05
Leave the team stronger
Your team inherits the platform, documentation, tooling, and modern delivery practices needed to keep improving it.
AI has changed the economics of modernization
Modernization is now faster, safer, and more commercially compelling.
Codebases can be understood faster
Features, dependencies, APIs, risks, and behaviour can be mapped from the codebase itself.
Documentation can be generated automatically
Detailed specs can be created from how the system actually works today.
Risk can be surfaced earlier
Hidden dependencies, outdated packages, security issues, and unknown complexity become clearer before delivery begins.
Parity can be tested more reliably
AI-assisted tests help prove the new platform matches what works today.
Our proprietary AI-driven process
Paloma Modernisation Engine™
Codebase Intelligence
Maps features, dependencies, domains, APIs, and risks from the system itself.
Specification Generator
Documents how the platform actually works today, reducing reliance on tribal knowledge.
Parity Harness
Validates that the modernised platform matches core legacy behaviour before release.
Release Safety Pack
Supports safer rollout with testing, monitoring, feature flags, and rollback planning.
Together, these tools reduce time to deliver by over 3x vs traditional methods, with higher reliability. This isn’t consultancy alone—it’s productised modernization, built by Paloma and battle-tested on real apps.
Best practice, baked in
Executives often ask:
Can this project improve how we build, release, and learn?
Paloma brings battle-tested best practices proven across digital products with millions of users and tailored to your context.
The result: You don’t just get a modernized platform. You can also inherit tooling, practices, and a delivery environment that help your team move faster with confidence.
Optimised for:
If you could move twice as fast, what would be possible?
This isn’t just a cost-out exercise. It’s an ambition upgrade.
Where modern platforms unlock possibility
More shots on goal
Faster cycles mean you can test bolder ideas, kill the duds early, and double down on winners without the drag of legacy systems.
Quality as a feature
With less time sunk into “keeping up,” you can redirect energy into features, polish, and performance.
New revenue streams
Modern platforms make it easier to launch integrations, open partner channels, embed new services, and create new customer value.
What changes
Idea-to-production lead time
months → weeks
Release cadence
monthly → weekly/daily with confidence
Experiment throughput
run more A/Bs, learn faster, waste less
Design consistency
a single system applied everywhere
Team focus
less platform work, more product craftsmanship
We help create the conditions where your teams can set a higher bar, pursue bigger bets, and deliver more beautiful, more valuable product.
We leave your team stronger
We don’t just deliver, we train your team to thrive in the new stack.
This training is part of our core offering, at no extra cost. Our goal is that your team owns the future without dependency on us.
