About this list
Automation at startup scale is usually assembly rather than model building, and the best-documented agencies here say so out loud. 010 Coding Collective's returns tool for Utilitarian runs as a white-label platform on the client's own AWS, and the study states plainly that no custom model was trained. Lizard Global's flagship automation for Company.Info crawled more than 40,000 pages in Python, Node and Playwright with no machine learning in it at all. Softspring's psychologist-matching platform calls a Google model for the match and keeps private patient data away from it by design. Softblues labels each flagship study with the stage it reached, including the ones that stopped at an audit or a proposal.
That candor is the useful signal, because the failure mode at this size is paying model-building prices for integration work. Ask each candidate which part of your problem needs a model at all—often none of it does—and who operates the automation once it is live. Then ask what happens when the third-party API changes its pricing or its behavior: on a runway measured in months, a dependency you cannot swap matters more than a few points of accuracy.

Expert Insight
Why startup fit matters for AI Automation
Startup budgets buy scoped builds, not programs—the agencies here document work shipped in weeks to months, priced for companies that measure runway.
At small agencies the case-study authors are the delivery team, which removes the seniority lottery that makes large firms risky for small engagements.
Code ownership decides whether the engagement was an asset or a dependency: every documented build here describes a system the client runs, and that question belongs in your first call.
Frequently asked questions
12 agencies in our directory combine verified startup client evidence with documented AI Automation work. The current top-ranked are OstraconAI, InData Labs, Opinov8 — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Published rates across this page's agencies run €20–300 per hour (median ~€65). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
Each listed agency has at least two documented, named startup clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.
3 of the agencies on this page document an embedded / team-extension working model. See the team-extension page for the full verified list, or check the engagement chips on individual profiles.
