We build custom software for the work no off-the-shelf tool fits: operations platforms, customer portals, internal tools, and multi-tenant systems that talk to your Stripe, Salesforce, or HubSpot data.

Local insight

On the ground in Washington, D.C..

The DC metro is two economies stitched together: the federal-and-association world inside the city and the contractor-and-data-center belt across Northern Virginia. Inside the District, the work skews toward law firms, lobbying and advocacy groups, accounting firms, and the trade associations clustered near K Street, all of which need polished, secure, content-heavy platforms and member portals that project institutional credibility. Across the river in Arlington, Tysons, and Reston, the defense-contracting and data-center density means a high bar for security and a B2B SaaS bench staffed by people who think about compliance reflexively. Real-estate teams work one of the wealthiest, most credential-dense buyer pools in the country. The engagements that fit here treat trust and security as first-class requirements, build for audiences that scrutinize provenance, and read the room: this is a market where being measured, accountable, and buttoned-up wins over being flashy. Decision cycles in DC run long because the buyers answer to boards, members, or compliance officers, so the partner who documents thoroughly and makes the security story easy to defend upward is the one who survives the procurement gauntlet the city is famous for.

Operating in Washington, D.C.

How the engagement adapts to a metro this size.

  • Paid discovery before any fixed bid

    Two weeks, scoped and paid. We map the workflow, talk to operators, and write a wireframe pack you can use even if you do not hire us. The bid that follows is a number, not a range.

  • Auth, billing, and roles solved on day one

    Clerk or WorkOS for auth. Stripe for billing. Role-based access control from the first sprint. These are solved problems and we do not re-solve them every engagement.

  • Postgres until you have a reason to leave

    Boring works. Postgres covers 95% of operator workloads. The migration to something exotic is real but cheap if you ever need it, and most teams never do.

  • Observability is not a phase-two project

    Sentry, Axiom, and a feature-flag layer ship with the first sprint. You cannot debug what you cannot see, and we will not hand off code we cannot diagnose.
