Construction firms in Latin America still run multimillion-dollar projects on WhatsApp groups, spreadsheets, and printed plans. Budgets drift, change orders get lost, and nobody knows the real margin until the project is over. The existing software was built for the US and never fit how teams here actually work.

Octar is a budgeting and project-control platform built specifically for LATAM construction. It connects the estimate, the live budget, and field progress in one place, so a project manager can see overruns the day they happen instead of three months later. Spanish-first, priced for the region, onboarded in days.

I founded the company and lead product end to end: discovery, roadmap, and most of the early UI. I sold the first ten accounts myself, wrote the support replies, and shipped features the same week a customer asked for them.

• $90K ARR reached without outside funding
• Adopted by construction firms managing 8-figure project portfolios
• Spanish-first product onboarded in days, not weeks
• Built and shipped the MVP solo before the first hire
