SaaS Development Company in Berlin

How close the product sits to regulated finance is the main driver on a Berlin SaaS build. That sorts into a focused B2B SaaS MVP at Berlin rates over four to six months, covering multi-tenant architecture, EU-region deployment, GDPR-aligned data model, billing, SSO, an initial DPIA, and a DORA register-of-information stub if finance-adjacent, a production SaaS platform with full role and permission system, audit logging, Stripe or Adyen billing, EU VAT OSS/IOSS, observability, BSI IT-Grundschutz baseline, and a NIS2 incident-response runbook, or a full BaaS or marketplace platform in the Solaris, Mambu, or Zalando Partner Programme mould including BaFin or DSA-adjacent compliance scaffolding. Berlin rates sit above Warsaw and Bucharest because of the Personio, N26, and Mambu talent premium but remain below Zurich and London. We quote fixed milestones rather than open T&M, and we invoice in EUR with USD optional for US parents.

BaFin (Bundesanstalt für Finanzdienstleistungsaufsicht) is Germany’s federal financial supervisor and the most demanding regulator most Berlin fintechs will face. Our BaFin-aligned engagements include §25a KWG model risk governance with documented model inventories, challenger testing, and four-eyes review for any decisioning model; KYC and onboarding flows built to GwG (Geldwäschegesetz) requirements with VideoIdent or AutoIdent partners; Sanktionslisten screening against EU consolidated and OFAC lists with continuous monitoring; PSD2 Strong Customer Authentication via 3DS2; transaction monitoring for AML with SAR (Suspicious Activity Report) workflows feeding goAML; and BAIT (Bankaufsichtliche Anforderungen an die IT) plus the new DORA Article 28 ICT third-party risk-management framework. We pattern after Solaris, Mambu, and N26 public disclosures and produce the documentation BaFin examiners and a §44 KWG audit would expect to see without rewriting.

The Digital Operational Resilience Act (DORA, Regulation 2022/2554) is fully applicable from 17 January 2025. It binds financial entities and their ICT third-party providers — including SaaS vendors serving banks and insurers — to five pillars: ICT risk management, incident reporting, digital operational resilience testing, ICT third-party risk management, and information sharing. Our DORA-aligned deliveries include an ICT risk-management framework aligned with Article 6, an incident classification and reporting flow feeding the major-incident notification timeline (initial within four hours of classification, intermediate, and final), a Threat-Led Penetration Testing (TLPT) readiness plan for entities in scope, a register of information template for ICT third-party arrangements (Article 28), and contractual clauses for subcontracting that BaFin and the Bundesbank will accept. SaaS platforms that serve regulated customers ship with DORA documentation packs the customer’s procurement team can hand to their compliance function on day one.

German labour law gives works councils strong co-determination rights under §87 BetrVG, particularly on technical systems that monitor employee behaviour or performance. Any HR SaaS deployed in Germany — whether ours or a Personio-style platform — must pass a Betriebsrat consultation, often formalised in a Betriebsvereinbarung (works agreement). Our HR SaaS engagements include a Betriebsrat consultation playbook with sample agendas, a list of features that typically require co-determination (login tracking, performance dashboards, AI-supported CV screening, sentiment analysis), data-minimisation patterns that satisfy §26 BDSG, role and permission models that limit manager-level visibility appropriately, and audit-log redaction tools so the works council can verify retention practice. For AI-supported HR features we add EU AI Act Annex III high-risk system controls — risk management, transparency, human oversight, and bias monitoring — before launch.

We default to AWS eu-central-1 (Frankfurt) plus eu-central-2 (Zurich) or eu-west-1 (Dublin) for DR, with row-level tenant isolation in PostgreSQL, per-tenant encryption keys via AWS KMS or HashiCorp Vault, and tenant-scoped backup and restore. For customers requiring full German jurisdiction we deploy on T-Systems Sovereign Cloud, Open Telekom Cloud, or IONOS Cloud, all operated by German-headquartered companies under German law without US Cloud Act exposure. Where customers in regulated industries demand customer-specific keys, we support BYOK (Bring Your Own Key) and external key management. Logging and observability stay inside the EU (Datadog EU region, Grafana Cloud EU, or self-hosted on the same region). Auftragsverarbeitungsverträge (Article 28 GDPR DPAs) name every subprocessor with location, and the customer’s DPO receives a Transfer Impact Assessment for any non-EU subprocessor in scope.

Yes. The EU Digital Services Act (Regulation 2022/2065) applies to online marketplaces with trader-traceability (Know Your Business Customer) obligations, statement-of-reasons workflows on content moderation, internal complaint-handling systems, and transparency reporting. Our marketplace SaaS stack ships KYBC flows that capture and verify trader identity, VAT IDs, and contact details, with periodic re-verification; statement-of-reasons templates for delistings and moderation actions; an internal complaints flow with response timelines; and DSA Article 24 transparency report tooling. For physical-goods marketplaces, we additionally integrate Extended Producer Responsibility registrations (LUCID and ZSVR for Germany’s VerpackG, plus equivalents in France, Spain, and Italy), EU VAT OSS/IOSS for cross-border B2C, and the GPSR (General Product Safety Regulation) traceability obligations effective December 2024. The result mirrors the Zalando Partner Programme onboarding template, scaled down for SME marketplaces.

A focused B2B SaaS MVP for a Berlin mittelstand or scale-up takes four to six months from kickoff to early-access, assuming clear product scope and no banking licence in the critical path. Weeks one to four cover discovery, regulatory-perimeter classification, architecture, and GDPR DPIA. Weeks five to fourteen cover multi-tenant build, billing, SSO, audit logging, and core feature work. Weeks fifteen to eighteen cover security hardening, NIS2 incident-response runbook, observability, and beta. Weeks nineteen to twenty-four cover early-access launch, customer onboarding, and the first round of customer DPO reviews. For BaFin-adjacent BaaS in the Solaris or Mambu pattern, add a four to six month regulatory-architecture phase and a TLPT-readiness plan. For HR SaaS in the Personio pattern, add a Betriebsrat consultation window of six to ten weeks. We have shipped to this cadence across fintech, HR, and marketplace verticals.

Most SaaS engineering does not qualify, but specific R&D components often do. Germany’s Forschungszulagengesetz provides a 25 percent refundable credit on eligible personnel costs up to EUR 10M per company per year (raised from EUR 4M in 2024), and applies to work done in-house or contracted to qualified providers — including our team. Eligible activity covers novel algorithmic work, architecture experimentation, and systematic investigation where the technical outcome is uncertain at the start. Examples in SaaS that often qualify include custom ML models embedded in the product, novel distributed-systems work, and security research; routine multi-tenant CRUD does not. We deliver time-tracked logs, technical narratives, experiment histories, and failed-hypothesis documentation aligned with the BSFZ (Bescheinigungsstelle Forschungszulage) certification process. Berlin clients can often stack Forschungszulage with Investitionsbank Berlin programmes. Final eligibility sits with your Steuerberater and the BSFZ.
