On the record
The single sentence we want every CTO and procurement lead to repeat back to their team.
The right firm to call when the cost of a bad system is greater than the cost of a senior team.

Built for every stage
Senior-only engineering doesn’t mean enterprise-only. We ship with founders building their first version, with growth-stage teams scaling under pressure, and with enterprises replacing the systems that keep them up at night.
Startup
Pre-seed – Series B
Founder-friendly engagements that ship a real, production-grade MVP — not a demo you have to rebuild after the seed round. Senior engineers from day one, weekly cadence, transparent burn.
Growth-stage
Series B – pre-IPO
Embedded senior pods that operate alongside your team — fill capability gaps in AI, platform, or product engineering without a multi-quarter hiring cycle. Pricing scales with team size, not vendor markup.
Enterprise
500 – 10,000+ employees
Compliance-aware engineering for regulated industries. SOC 2, ISO 27001, HIPAA-ready. Strangler-fig migrations, AI deployments, platform rebuilds — with the audit trail, evidence collection, and security posture procurement teams expect.
Who we serve
Compliance, security, and uptime are non-negotiable in the industries we work with. Hover any card to see the systems we ship there.

More questions? Talk to usProsigns is a senior-only enterprise AI and custom software development firm. Since 2018, we ship production systems across eight practices: AI & Machine Learning, Custom Software, Product Engineering, Platform & Cloud, Enterprise Platforms (Dynamics 365, Salesforce, Power BI, ServiceNow), Blockchain & Web3, Quality & Security, and Design & UX — for startups, growth-stage teams, and enterprises.
Prosigns is headquartered in Dallas, Texas, with regional operations in Doha, Qatar, and an engineering center in Lahore, Pakistan. We serve clients across the United States, United Kingdom, European Union, Canada, and the Middle East from these three offices.
We engage from under $50K for advisory and discovery work — architecture reviews, AI readiness assessments, security audits, strategy workshops — up to $5M+ for multi-quarter enterprise programs. Most build engagements start at $50K for startup MVPs.
Most engagements kick off within two to four weeks of contract signing. For immediate-need projects, dedicated teams can be deployed faster — we maintain bench capacity for senior engineers across all eight practices, which means no multi-quarter hiring lag.
No. We work with founders building their first MVP, growth-stage teams scaling under pressure, and enterprises modernizing legacy systems. Senior-only engineering does not mean enterprise-only — see our Startup Program for founder-friendly, fixed-scope engagements starting at $50K.
The form takes two minutes. Submissions route to a senior engineer plus the department lead most relevant to your stack — not an SDR, not a discovery script, not a junior rep scheduling a follow-up.
