Side by side
Published data on both agencies. Where one side measurably differs, the dot marks it: the higher score, the lower published rate, the larger team, the more recent review. Which of those is an advantage depends on your brief.

What we said about each
Our take on Twistag
The best-documented AI portfolio on this page, and the detail is where the value is. For the manufacturer Aralab, an accounts-payable agent reads any supplier PDF with Claude while deterministic code independently recalculates every line total, unit price and tax figure against the matched purchase order: the model proposes, the validation engine verifies. It shipped in six weeks with one engineer, handles more than 2,000 invoices a month, and moved three finance people off transcription.

Read the full assessment →Our take on Vstorm
Three named-client case studies carry the stack and the numbers: Mixam's order agent is live at 10,000+ daily users and about 100,000 orders a month, Synera's text-to-workflow agent runs inside the product behind a validator that rejects illegal code before it reaches the interpreter, and the Schmitt-Thompson clinical triage system is scored against 591 nurse-validated scenarios. That write-up also publishes what still fails—no positive triage question found after correct guideline selection…

Where each agency measurably leads on the published data — team capacity, declared specializations, editorial scoring, and rates where both publish them. Use these to match an agency to your project priorities.
Choose Twistag if you need
- a more cost-effective engagement (~40% lower rate)
- disclosed specialization in FinTech
- broader service offering — also covers AI Automation
Choose Vstorm if you need
- disclosed specialization in Healthcare
- broader service offering — also covers AI Consulting and Generative AI
Strengths and watch-outs
Both upsides and risks, straight from our editorial assessments.
Twistag
Strengths
- The hybrid pattern is published, not implied: the language model interprets and deterministic code independently recalculates every figure against the purchase order
- Observability ships with the system—LangFuse traces every call with prompt versions and per-invoice cost visible in real time, so the workflow cannot get quietly expensive
- Models sit behind a provider abstraction and were swapped twice on one engagement without the product changing shape
Watch-outs
- The largest engagement, the regulatory compliance platform, is anonymized—ask for a speakable reference at one of the brands running it
- The PepTalk system publishes no measured outcome by the agency's own admission; ask what the volume and turnaround figures are now
- No headcount is published against a decade of trading—ask how many engineers would be forward-deployed on your build and for how long
Vstorm
Strengths
- Case studies publish the architecture, not only the outcome: a four-stage PydanticAI pipeline with Logfire tracing for clinical triage, and a validator loop between the LLM and Synera's interpreter
- Results stated against baselines and expert panels: 44% raw-LLM to 93% disposition accuracy over 591 scenarios, and 95.4% workflow success at Mixam against the client's 80% target
- Rate sits at €85–130/hr, inside the European range on our rate index, against agents already carrying production volume—10,000+ daily users at Mixam
Watch-outs
- About half the published case studies are anonymized—a US Medicare Advantage payer, a US telecom, a construction platform—so ask for a speakable reference on the engagement closest to yours
- The team page names four people—two founders, an AI engineering lead, a recruiter—against a stated 25+ engineers; ask who builds and who operates the system after handover
- Tetra Pak, Mercedes-Benz and Intel appear on the about page with one line and no case study, and the Intel-branded kernel port is filed under a confidential client—ask what shipped in each

Pricing math
What a 12-week engagement at one full-time equivalent (~480 hours) costs at each agency’s published rate. An arithmetic projection, not a quote — real scopes move with seniority mix and team shape.
Twistag
Rate: €45-85/hr
€21,600–€40,800
Vstorm
Rate: €85-130/hr
€40,800–€62,400
At this scope the published midpoints are about €20,400 apart, with Twistag lower. Vstorm publishes Healthcare work that Twistag does not — that is the one difference on this page that bears on the gap. If your brief does not touch it, the gap is buying something this comparison cannot see.
Frequently asked questions
- Which is cheaper, Twistag or Vstorm?
- Twistag is cheaper by roughly 40% — €65/hr median vs €108/hr at Vstorm. Published rates cover different things at different agencies — seniority mix, discovery and included revisions are the usual variables — so treat the gap as a question to ask, not a verdict.
- Which has more SaaS & B2B experience, Twistag or Vstorm?
- Both agencies show documented SaaS & B2B work and have similar industry breadth. Compare directly on the agency profiles: Twistag and Vstorm.
- Which scores higher overall, Twistag or Vstorm?
- Both score equally well overall (73/100). The deciding factor is specialization — see the editorial quotes and Strengths sections above. Full methodology.
- When should I consider both Twistag and Vstorm?
- Consider running parallel discovery briefs with Twistag and Vstorm if your project spans multiple workstreams, you want competitive proposals to compare scope and approach, or you're undecided between the specialization angles each brings (see the Best for cards above). Most engagements ultimately go with one — but the parallel-brief phase is a low-cost way to validate fit.
