Sächsische Aufbaubank

What Sächsische Aufbaubank does

Sächsische Aufbaubank (SAB) is the state development bank (Förderbank) of the Free State of Saxony, structured as a public-law institution (Anstalt des öffentlichen Rechts) under the FörderbankG Sachsen and supervised by BaFin and the Saxon State Ministry of Finance. Founded in 1991 and headquartered in Leipzig with customer centers in Dresden and Chemnitz, SAB administers and distributes consolidated state, federal (KfW, Landwirtschaftliche Rentenbank), and EU (ERDF) development financing for individuals, SMEs and startups, municipalities, universities, and associations within Saxony's borders. Its product portfolio spans the Sachsenkredit family of subsidized loans (Universal, Gründen und Wachsen, Energie und Speicher, Nachhaltiges Kommunaldarlehen), the DFM directive microloans (Mikrodarlehen, Nachrangdarlehen Invest, Markteinführungsdarlehen, Digitalisierungsdarlehen), Konsortialkredite for syndicated projects, the Balkonkraftwerke plug-in PV grant program (300 EUR per unit), and Aufstiegs-BAföG support.

SAB's technology stack centers on the digital Förderportal (portal.sab.sachsen.de) — the unified application platform supporting Verimi-based e-identification (QES, photo, video, eID), digital signatures, and status tracking — complemented by the SAB-Partnerportal für Hausbanken which provides OpenID Connect-authenticated digital data exchange with the network of partner commercial and savings banks that originate Sachsenkredite applications. The SABRINA chatbot provides AI-assisted text-based Q&A on funding programs. Marketing and consent tooling is built on Brevo, Usercentrics, Matomo, Microsoft Teams, and event platforms (eveeno, Mentimeter). All sites are GDPR/DSGVO-compliant and partially BFSG-accessible (declaration dated June 25, 2025).

SAB's business model combines three revenue streams: (1) interest income on subsidized development loans priced at risk-adjusted, below-market rates with fixed terms up to 10–15 years and loan sizes from 35,000 EUR to 5,000,000 EUR (Sachsenkredit) or 5M+ EUR (Konsortialkredite); (2) grant disbursement administration for programs such as the 300 EUR-per-unit Balkonkraftwerke subsidy; and (3) guarantee and counter-guarantee fees (Bürgschaften) supporting SME financing. Distribution operates primarily through Hausbanken partner banks intermediating Sachsenkredite, with direct digital application available for municipalities and the Balkonkraftwerke program, supplemented by customer centers in Leipzig, Dresden, Chemnitz and regional Beratertage advisory events across Saxon cities.

Revenue model

1. Loan Interest Income: SAB provides subsidized development loans at favorable interest rates. The bank earns interest income on its loan portfolio, with interest rates typically below market rates due to public funding support. Interest terms include fixed rates for periods up to 10-15 years.
2. Grant Disbursement (Zuschüsse): SAB administers grant programs that provide non-repayable funds for qualifying projects. These include balcony power plant subsidies (300 EUR fixed grant), energy efficiency grants, and various other state-funded programs. SAB acts as administrator rather than primary funder for these streams.
3. Guarantee/Bonding Fees (Bürgschaften): SAB provides guarantees and bonds to support SME financing, accepting a fee or commission for counter-guarantees.
