Common questions about Diffco.
Diffco has earned rankings on 6 AgencyCluster lists: Top 50 Staff Augmentation / Dedicated Teams, Top 50 Generative AI Development, Top 25 Product Engineering (SaaS) in California, and 3 more. Their highest AgencyCluster Score is 80/100. Rankings are merit-based and determined by evidence across six evaluation pillars — agencies cannot pay for higher positions.
In our evaluation for Generative AI Development, Diffco scores 80/100 overall. Their strongest areas are Credibility, Proof of Work & Outcomes, Reputation, Category Fit, Delivery Maturity, Freshness. A high Outcomes score means they have verifiable case studies with measurable results — the most heavily weighted factor in our methodology.
Diffco was founded in 2008, giving them over a decade of experience in product engineering (saas). In an industry where many agencies are less than 5 years old, 18+ years of sustained operations signals stability, client retention, and the ability to adapt through multiple technology cycles. Today, the team is small team.
Diffco is listed across 3 categories on AgencyCluster: Product Engineering (SaaS), Staff Augmentation / Dedicated Teams, Generative AI Development. This indicates a full-service or multi-discipline capability. Multi-service agencies can be advantageous when your project spans several disciplines (e.g., design + development + marketing). However, check their scores per category — an agency may be strong in web development but less specialized in, say, AI/ML. Product engineering agencies think like CTOs — they consider scalability, technical debt, security, and operational readiness from day one. This prevents the costly 'rebuild from scratch' moment that hits many startups at scale.
A SaaS MVP costs $80K–$300K. Full product engineering with dedicated teams runs $30K–$80K/month. Post-launch iteration and scaling typically costs $20K–$50K/month. These are industry benchmarks for product engineering (saas) agencies at the level AgencyCluster curates. Actual pricing for Diffco will depend on project scope, timeline, and complexity — contact the agency directly for a custom quote.

Unlike self-serve directories, AgencyCluster does not accept automated submissions — every agency is evaluated manually before being published. Our vetting covers identity verification (website, LinkedIn, domain age), business legitimacy (years of operation, team size, registered presence), evidence of work (case studies, portfolio, client outcomes), reputation checks across third-party platforms, activeness and freshness of their online presence, and screening for red flags including misconduct, fraud, or misleading claims. Agencies that fail any critical check are not listed. For Diffco, verified signals include a functioning website, LinkedIn company profile, 18+ years of operating history (founded 2008), 6 earned rankings on curated top lists.
