COMPANIES THAT CAN'T AFFORD A VENDOR THAT DOESN'T UNDERSTAND THE BUSINESS.

01

Series A+ startups scaling

Founders past product-market fit, building something serious. You need velocity without sacrificing architecture, with senior engineers in your timezone.

02

Mid-market teams overloaded

Engineering orgs that need a true product partner — not staff augmentation from a vendor 12 hours off your timezone.

03

Companies that picked wrong before

You know the difference between engineers who own outcomes and vendors who close tickets. So do we.

Engagements typically start at USD $25k. We don't take smaller projects — we'd rather focus the team on substantial problems.

// WHY_BASE_COMPUTING

WHY US, AND NOT THE OTHER FACTORY.

01

In-house team, zero subcontracting

Every engineer on your project is a Base Computing full-time hire in Medellín. No outsourcing, no agency-of-agencies. If a specialist isn't on staff, we tell you and we decide together how to bring them in.

02

We operate our own products

PLASMA and Trace, both in production with paying customers. We know what hurts in operation because we live it daily on our own systems — the same discipline we apply to them is what we bring to your project.

03

Senior team, in your timezone

100% senior engineers. Medellín runs on US Central / Eastern time (no DST shift) — we join your standups, we don't reply to them the next morning.

04

AI and Blockchain — actually shipped.

We've shipped predictive AI in production (PLASMA) and we co-founded a Web3 protocol (Basis Network). Not PowerPoint demos — code running with paying customers.

05

Asymmetric risk reversal

First functional prototype in 4 weeks. If we don't deliver on time, the first month is free. We carry the risk, not you.

// HOW_WE_ENGAGE

THREE WAYS TO WORK WITH US.

01

Fixed-scope project

Defined scope. Fixed timeline and price. Best for MVPs, migrations, modernizations.

02

Dedicated team

2–5 senior engineers, full-time, integrated with your team. 3-month minimum engagement.

03

Architect on retainer

Senior architecture access for CTOs without the full-time hire. 20–40 hrs / month.

// METHODOLOGY

FROM PROBLEM TO PRODUCTION

We deconstruct chaos to build order. A rigorous path from problem to long-term operation.

01

Diagnostic

Deep system audit, business-context interviews, bottleneck identification.

02

Architect

Custom roadmap, stack selection, milestone plan tailored to scale.

03

Execute

Agile delivery with zero-downtime integration. We ship, you operate.

04

Operate

Ongoing support, observability, and product evolution. We don't disappear at handoff.

// QUESTIONS_WE_GET

WHAT EVERYONE ASKS BEFORE SIGNING.

Eight questions we get on every first call. Answered here so you don't have to wait for ours.

01

Where are you based, and how does timezone work?

+

Medellín, Colombia. Same timezone as US Central / Eastern (no DST shift). We overlap fully with US business hours — we join your standups, we don't reply to them the next morning.

02

What does a typical engagement cost?

+

Floor: USD $25k. A fixed-scope 3–6 month project usually lands between $40k and $150k. A dedicated team of 3 senior engineers for 6 months runs around $120k. After the discovery call we deliver three scoped scenarios so you choose.

03

Who owns the code and IP?

+

You. 100%, day one. All code, IP, infrastructure, and repositories belong to your company from the start. No proprietary stack, no vendor lock-in, no hidden licenses. Standard US-style work-for-hire contracts available.

04

What if you miss the deadline?

+

First month is on us. Every project is signed with verifiable milestones and payments tied to delivery — no delivery, no payment. We carry the risk, not you.

05

How senior is 'senior'?

+

Minimum 5 years of production engineering, demonstrated deployments, and the authority to make architecture decisions without supervision. Most of our team is 7–12 years in. We don't bench juniors on client work — every engineer billed to your project has owned production systems before.

06

Do you sub-contract?

+

No. Zero subcontracting. Every engineer on your project is a Base Computing employee in Medellín. If we need a specialist we don't have internally, we tell you and we decide together how to proceed.

07

How do you handle US contracts, IP, and compliance?

+

Standard US work-for-hire contracts, NDA before any deep conversation, SOC 2-style controls on infra, GDPR-compliant where applicable. We've shipped under AWS for US-based clients before. Your legal team will recognize the structure.

08

What about post-launch support?

+

Three options: (1) 90-day no-cost warranty for bugs originating in our code. (2) Monthly support retainer for maintenance and evolution, from $2k/mo. (3) Architect-on-retainer for ongoing advisory. We don't disappear at handoff.
