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 Altar.io
A product studio for funded startups, and the case studies measure the client rather than the work. The Apiax study reports that the fintech went on to raise more than eight million dollars, win startup awards and grow past 75 people across five offices. The Krepling study opens with $4.

The NOS work is the anchor: a GenOS-orchestrated invoice pipeline that now handles around 65% of roughly 20,000 supplier invoices a month end to end, matching them to SAP purchase orders and routing the ambiguous rest to a 20-person review team, plus UVA, a retrieval assistant over 15,000-plus documentation pages that operators rate at 87% answer accuracy on the 20% of calls where it is used. Outside the telco, the Heineken routing engine (an OSRM duration matrix plus constraint optimization)…

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 Altar.io if you need
- closer collaboration at a smaller team scale
- disclosed specialization in SaaS & B2B / E-commerce
Choose DareData if you need
- larger team capacity for multi-stream or enterprise-scale programs
- disclosed specialization in Manufacturing
- a higher overall editorial score
Strengths and watch-outs
Both upsides and risks, straight from our editorial assessments.
Altar.io
Strengths
- Twenty-six published case studies with the client named on sixteen of them, which is unusual volume for a studio of this size
- The startup track record is checkable: Apiax raised more than eight million dollars and grew past 75 people after the engagement
- Consistent focus on regulated fintech and commerce products rather than a scatter of unrelated verticals
Watch-outs
- The studies report the client's funding and awards rather than what Altar built or how it performed—ask for the technical scope and the engineering outcome
- Most of the AI belongs to the client's product; ask which models the team trained, evaluated or operated itself
- No rate and no headcount are published—confirm team size and cost before a fixed-scope build
DareData
Strengths
- Directory rates of €45–85/h against named enterprise production systems
- Engineering writing with substance: a nugget-based RAG evaluation piece drawn from production work (August 2026) and a LiteLLM supply-chain advisory, next to 18 published success stories
- Third-party signals: Clutch 100 fastest-growing 2023, Deloitte Fast 50 Portugal 2025, Google Cloud, Microsoft and NVIDIA partner badges, and 130-plus specialists reported in March 2026
Watch-outs
- NOS holds a 20% stake in DareData and supplies four of the 18 published studies—ask for a speakable reference outside the NOS group
- The homepage claims 95% production deployments and €100M-plus value generated with nothing on the site behind either figure—ask how they are counted
- GenOS is the firm's own platform and sits under the invoice, legal and Greenvolt work—confirm licensing terms and what your team can operate if the engagement ends
Service coverage
Both agencies cover the same services — on this axis there is nothing to separate them, so decide on the evidence behind the work rather than its labels.
Industry coverage
Where the two overlap, and where each covers ground the other does not.
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.

DareData
Rate: €45-85/hr
€21,600–€40,800
Only DareData publishes a rate, so there is no gap to measure. Altar.io quotes per engagement — ask for a rate card early, since a comparison that starts on scope and ends on price tends to end late.
Frequently asked questions
- Which has more FinTech experience, Altar.io or DareData?
- Both agencies show documented FinTech work. Altar.io has the broader industry stack overall, with disclosed experience in SaaS & B2B, E-commerce beyond their shared focus.
- Which scores higher overall, Altar.io or DareData?
- DareData scores 64/100, 11.2 points higher than Altar.io at 52.8/100. See our methodology for how scores are calculated.
- Which is faster to engage, Altar.io or DareData?
- Neither publishes lead times, so this is a read on team size rather than a measured answer. Altar.io runs the smaller team, which usually means fewer procurement gates and a shorter path to kickoff. DareData runs a larger one, which tends to mean more steps but more capacity to start parallel workstreams. Current kickoff availability is the number that actually decides it — ask both.
- When should I consider both Altar.io and DareData?
- Consider running parallel discovery briefs with Altar.io and DareData 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.
