A AWS shortlist gets useful once you stop comparing capability decks and start comparing how each provider handles AWS and Lambda when a deadline is fixed. Judge them on the second year rather than the first sprint: AWS projects rarely fail at the start, they fail when nobody can safely change the code.
Entry 01 is ours and is marked as such. Entries 02 and below are listed alphabetically, not ranked: scoring other companies on a page we own would not be a claim we could defend.
Best for: Companies that want US-hours coverage and EU engineering standards without paying a full onshore agency rate. Startups backed by our clients have raised over $120M, and the group has delivered 350+ client projects.
Trade-off: We are a marketplace first: you interview and choose the engineers. If you want a vendor to absorb the whole problem with no involvement from you, a traditional agency is a closer fit.

Best for: Enterprise transformation programs across many systems
Trade-off: Cost structure and governance overhead make it a poor fit for small teams
Best for: Cloud platform and distributed-ledger projects
Trade-off: Specialist focus outside mainstream application work
Best for: Retail and commerce modernization at scale
Trade-off: Concentrated in a few verticals rather than general-purpose
Best for: Long-term managed services and large ERP estates
Trade-off: Contracting cycle and minimum size rule out most mid-market projects
Best for: Regulated-industry software with compliance requirements
Trade-off: Mid-market pricing above pure offshore options
Best for: Financial services and automotive engineering programs
Trade-off: Enterprise contracting, with the lead time that implies
Best for: Enterprise platform work with onshore project leadership
Trade-off: Onshore rates with offshore delivery blended in
Best for: Running cloud infrastructure you do not want to operate yourself
Trade-off: Managed services model, less suited to bespoke application work
Best for: US companies that want consultants physically close to the business
Trade-off: Onshore rates, and delivery capacity depends on the local office
Best for: Platform and data programs needing sustained team capacity
Trade-off: Sized for programs rather than for one or two engineers
Screen on depth in AWS and Lambda rather than on a list of logos. A provider that can walk through a decision they made about AWS on a real system, including what they got wrong, is demonstrating the thing you are paying for. Anyone who answers in generalities will also answer your production questions in generalities.
Budget for the part nobody quotes: onboarding into your domain. Even a strong aws team spends its first two weeks learning what your system does and why. Providers who price that honestly finish closer to their estimate than the ones who pretend it does not exist.
Red flags that should end the conversation
It depends on what the system has to do and who maintains it afterwards. A provider worth hiring will tell you when a more common stack would be cheaper to staff, and that conversation is worth having before the contract rather than after.
Yes, and it is the more common engagement. Expect an assessment first: reading the code, measuring what is slow or fragile, and agreeing what stays. Anyone who proposes a rewrite before that assessment is quoting the version of the project that fails most often.
