StepTo case studies:
real projects, measurable outcomes.
StepTo builds engineering teams that ship, from platform rebuilds to dedicated squads embedded in your workflow. Here's what we've delivered.
What Do These Four Engagements Have in Common?
Four engagements, four different starting problems: a Rails monolith that had stopped shipping, a two-person engineering team that needed to double its product surface, a support queue outgrowing its headcount, and a payments core that could not pass a compliance re-audit. What they share is the shape of the work. Each was delivered by a dedicated StepTo squad of three to six engineers over a defined window of four to eighteen months, and each case study reports the team size, a phase-by-phase timeline, the tech stack, and Key Results with the baseline each figure was measured against.
The headline figures are before-and-after comparisons against each client's own prior numbers. The e-commerce rebuild ran the new storefront as a 50/50 A/B for 30 days before full cutover, then measured results 90 days after cutover. The RAG support system and the fintech rebuild were both measured over the quarter following full rollout, the fintech one alongside the recertification audit itself; its 18× reconciliation figure is the same month-end close, same team, timed before and after. The dedicated React team is compared quarter-over-quarter: 14 features shipped in the first quarter against 3 in the quarter before.
Which case study should you read first?
- If a legacy platform is slowing releases and hurting conversion, read the E-Commerce Platform Rebuild: StepTo replaced a 340,000-line Rails monolith with a headless Next.js storefront and three Node.js services, migrated with zero downtime.
- If you need engineering capacity faster than local hiring allows, read the Dedicated React Team: StepTo took a Series A startup from 3 features a quarter to 14, at roughly 40% below equivalent German hiring costs.
- If support volume is outgrowing headcount, read AI Support Automation with RAG: StepTo built retrieval over docs, runbooks and resolved tickets, with every AI-drafted reply reviewed by an agent before it sends.
- If you face a regulatory deadline on a system that was built quickly, read the Fintech Payments Compliance Rebuild: StepTo built an event-sourced ledger and migrated each payment rail in shadow mode with zero processing downtime.
What Problems Has StepTo Solved for Clients?
The challenges we've tackled and the outcomes we've delivered, with the headline result quoted from each case study.
E-Commerce Platform Rebuild
Series B Retail SaaS, Netherlands
Legacy monolith causing 8-second load times and blocking feature releases for 6+ months.
Result, quoted from the StepTo case study: “Post-launch results measured over 90 days: LCP dropped from 8.2 seconds to 0.5 seconds (94% faster), conversion rate increased by 31%, and release cadence improved from bi-monthly to weekly (3× faster).”
Dedicated React Team: Shipping in 5-Day Cycles
Series A SaaS Startup, Germany
A 2-person engineering team needed to double product surface within 12 months for Series B, with German hiring timelines running 4–6 months per role.
Result, quoted from the StepTo case study: “The team shipped 14 features in their first quarter, up from 3 in the prior quarter. Time-to-feature dropped from 3 weeks to 5 days.”
AI Support Automation with RAG
Series B B2B SaaS Platform
Support ticket volume outpacing the team, with institutional knowledge scattered across Slack and Notion instead of searchable at query time.
Result, quoted from the StepTo case study: “Results measured over the following quarter: average first-response time dropped 70% (from ~5.5 hours to under 100 minutes), 38% of tier-1 tickets were fully auto-resolved with no human touch, and average handle time for tickets still requiring a human agent fell 45%.”
Fintech Payments Compliance Rebuild
Series B Payments Fintech, Lithuania
Monolithic payments core with no clean audit trail was blocking a compliance recertification with a hard deadline.
Result, quoted from the StepTo case study: “recertification passed on schedule with zero critical findings, reconciliation time cut 18× (from 3 days to under 4 hours), reconciliation discrepancies down 92%, and €42M in transaction volume processed during the migration with zero missed or duplicate transactions.”
How Should You Read These Case Studies?
StepTo identifies clients by funding stage, sector and, where given, country rather than by name, and every figure on a case-study page is specific to that one engagement. Where a number needs context, the page's FAQ explains how it was measured, for example how the 18× reconciliation figure was timed.
Team sizes and phase timelines on these pages are what StepTo actually staffed, so they are a fair guide to a comparable engagement. For how a team is assembled, trialled and scaled, see how StepTo works; for what a dedicated team or fixed-scope project costs, see pricing.
