Constela Digital · GPU-native bioprocess platform

Test the bioreactor before you build it.

One loop that turns a process idea into simulated, costed and ranked options, keeps the running reactor under watch, and learns from every lab, pilot and plant run.

01 · Who we are

Bioprocess engineering and HPC, in one team.

CEO · Bioprocesses and AI

Simone Perazzoli, PhD

Environmental engineer with a PhD in Chemical Engineering from the Federal University of Santa Catarina, Brazil, on biotechnological processes: biomethane from microalgae, nitrifying bacteria and microbial electrochemical cells for water treatment. More than 300 citations. Now a machine learning engineer building platforms for process automation, and completing a second degree in Artificial Intelligence.

Brings what the microbes need, what the data says, and how AI should reason about both.

HPC and GPU-native simulation

José Pedro de Santana Neto

Software engineer (University of Brasília) with an MSc in Mechanical Engineering on lattice Boltzmann methods (Federal University of Santa Catarina), completing a PhD in Computer Science specialized in HPC at the Federal University of Paraná. Built high-performance lattice Boltzmann software at NUMECA International in Belgium, now part of Cadence, and was a research associate in HPC simulation at the University of Geneva.

Brings the physics inside the vessel, written from the compiler up and resident on the GPU.

02 · What we want

Move the expensive surprise to the start of the project.

In a flask every cell sees the same conditions. In a production tank, cells travel through zones of excess substrate, starvation and dissolved gas, again and again. Those gradients change yield, and they usually show up at pilot or plant scale, years into the work.

Early cost estimates carry wide ranges for the same reason: the process data that would narrow them does not exist yet. We want that data to exist on day one, as a simulation you can question.

What one cell sees on one circulation loop

Near the feedexcess substrate, by-products, dissolved gas builds up
In the bulklimitation, the regime the process was designed for
Far from itstarvation, cells slow down

What success looks like

Success is moving the expensive surprises of bioprocess scale-up from the plant to the model, where they are cheap.
03 · What we offer

See what every cell sees.

Each simulated microbe is a particle carried by the resolved flow. It records the substrate, dissolved gas and shear on its path, grows and produces from what it meets, and returns gas to the liquid as bubbles that rise and exchange with it.

What a first study delivers

01

A flow map of your vessel

Mixing time, power draw and dead zones, checked against your own measurements.

02

What your cells see

The substrate, gas and shear each cell meets, ready for your kinetic model.

03

Gas, from the liquid to the outlet

Dissolved gases, bubbles and the composition of the gas leaving the vessel.

04

Ranked options

Design and operating choices ranked, with the numbers your economics needs.

Each deliverable comes with an acceptance criterion agreed before the runs.

04 · How we help

One platform, one loop.

AI agents read the requirements and drive the work. Fast learned models sweep the design space, high-fidelity solvers confirm the best candidates, techno-economic analysis ranks them, and sensors on real bioreactors feed the results back, so each cycle starts from better models.

04 · How we help · Operate

Keep the reactor running, and see trouble hours before it arrives.

The platform that designs the process also watches it run. Site reliability engineering, applied to bioreactors: live monitoring, automatic alerts, service levels agreed in advance, a prepared incident response, and a forecast of the reactor state hours ahead.

MONITOR · 24/7

Every vessel, live

pH, dissolved gases, exhaust gas, temperature, feed and level, checked against limits and against what the model expects.

ALERT · AUTOMATIC

The right person, at once

A deviation raises an alert the moment it appears, routed to whoever is on call, with context.

RESPOND · INCIDENT PLAN

Back to target state

A prepared runbook: contain, communicate, bring the reactor back to its target state, review the cause.

PREDICT · 1 TO 5 H AHEAD

Failures seen before they happen

Sensor data feeds models that forecast the reactor state and flag a drifting variable before its limit.
