Tech Consulting That
Makes Waves
Outcomes Over Hours - from Ripple to Rollout.
Thalassis is a boutique strategy and engineering firm trusted by global enterprises to design, build, and run mission-critical platforms—on time, on budget, with purpose.
Radical accountability runs through everything we do—from planning to delivery to billing—so you get real results and consistent quality from day 1 to 1000.
What We Do
Thalassis was founded on a simple idea: strategy is worthless until it ships.
We help medium-to-large enterprises build software that moves the business forward. Whether you're launching something new, fixing what's broken, or upgrading outdated systems, we bring the clarity, accountability, and execution to deliver.
Our teams combine senior consultants, architects, engineers, and product experts to deliver from strategy through execution, with full accountability at every stage.
We’ve supported clients across regulated and operationally intensive sectors—including aviation, payments, capital markets, construction, energy, and healthcare — where reliability, compliance, and time-to-market are critical.

Thalassis SAFSG Registry
The Thalassis SAFSG Registry is Asia's first end-to-end registry
for Sustainable Aviation Fuel (SAF) credits - built, operated,
and secured by a Singapore-native company.
Designed to track, verify, and issue SAF credits aligned with
international standards (ICAO CORSIA, RSB, IATA), SAFSG
ensures full traceability, zero double-counting, and
regulatory-grade integrity for every credit issued.

Our Approach
Here’s how we scope, price, and deliver work—from the first conversation to the final invoice.
Each engagement starts with a Scope of Work (SOW)—a shared understanding of what we’re solving.
We break down your goals into tangible deliverables called Units of Work (UOW).
Each UOW is estimated in Full Stack Days (FSDs): one day of coordinated output from a core contributor and supporting team, rather than just an average (blended) rate.
You’ll see your entire project—scope, delivery, and cost—measured in the same unit
Fixed Billing
Pay the upper bound of our estimate (the pessimistic case). You cap risk and lock in a known cost.
Flexible Billing
Pay only for the actual FSDs used. If a UOW takes less time, you pay less. If it takes more, you’re billed only for what was actually consumed.
Every month, you get a clear invoice—our line items are deliverables (UOWs), not resources.

Why Thalassis?
You Pay for Results, Not Hours
We don’t charge by time or role. We bill based on completed work—using a single unit called a Full Stack Day (FSD). It keeps everything simple and trackable.
Senior Teams from Day One
No junior staff learning on your time. You work directly with experienced consultants, engineers, and architects who know how to deliver.
Strategy and Delivery Under One Roof
We don’t hand off work between teams. The same people who help you define the solution are the ones who build it—start to finish.
