Software house for brokerage firms: custom technology for CTVMs and DTVMs

Few sectors depend on technology as much as financial intermediation. In a brokerage firm, software is not a support function: it is the operation itself. Every order sent, every position under custody and every regulatory report runs through systems that must work in real time, under constant audit and with no room for downtime.

At the same time, it is a sector poorly served by generic software. Off-the-shelf tools solve what is common to any company, but a brokerage's differentiation, the products it launches, the experience it offers investors and the efficiency of its back office, depends on custom development. That is where a software house with maturity in critical environments comes in. At Espresso Labs, this is not a theoretical thesis: we have worked alongside CM Capital for more than 5 years, in a continuous partnership developing and maintaining systems for the brokerage.

CTVM and DTVM: what they are and why it matters for technology

Two acronyms appear in any conversation about the Brazilian market: CTVM (Corretora de Títulos e Valores Mobiliários, a securities brokerage) and DTVM (Distribuidora de Títulos e Valores Mobiliários, a securities dealer). Both are institutions licensed by the Central Bank of Brazil and supervised by the CVM, Brazil's securities commission, to intermediate the trading of assets. Since 2009, when a joint decision by the Central Bank and the CVM authorized DTVMs to trade directly on exchanges, the practical difference between the two figures has all but disappeared.

For technology, what matters is what they share: both operate under heavy regulation, connect to the market's core infrastructure (the exchange, clearing houses, Central Bank systems) and are accountable for third-party money and assets. Any software built for a CTVM or DTVM is born with security, audit trail and availability requirements that ordinary corporate systems never face.

The ecosystem a brokerage's software must talk to

Building for brokerage firms is, above all, building integrations. The daily operation of a CTVM or DTVM connects to an extensive ecosystem:

• B3, the Brazilian stock exchange (heir to the former Bovespa and BM&F), with its trading, post-trade and custody environments, including order routing via the FIX protocol and market data feeds;
• Sinacor, the standard back-office system of Brazilian brokerages, which concentrates client registration, custody, settlement and much of the operational routine, and with which virtually any new solution must integrate;
• Trading platforms used by end clients, such as proprietary home brokers, Profit (Nelogica), Tryd and MetaTrader, each with its own integration channels;
• Market data providers and market infrastructure, plus Central Bank systems for government bonds and settlement, such as Selic and STR;
• Supervision and self-regulation bodies, such as the CVM, the Central Bank and BSM Market Supervision, which require reports, audit trails and specific operational controls.

Each of these endpoints has its own protocol, certification and operating windows. A software house serving the sector needs to know this map, or the project discovers the obstacles the worst way possible: in production.

What a brokerage typically needs to build

In projects for the investment sector, demands usually fall into four groups:

• Investor experience: client apps and portals, digital onboarding with registration validation and suitability, logged-in areas with consolidated positions, statements and tax reports.
• Back-office automation: routines that today run on spreadsheets around Sinacor, reconciliations, corporate action processing, custody and transfer calculations, regulatory file generation.
• Integrations and APIs: connecting the brokerage's core to partners, independent agents, white-label platforms, Open Finance and the systems of asset managers and funds.
• Data and intelligence: consolidating trading and custody data for BI, transaction monitoring for anti-money-laundering and support for compliance obligations.

The pattern uniting all four groups: none of it can stop, all of it needs logging and audit trails, and any error has direct financial consequences.

Dedicated squads: scaling the brokerage's team without starting from scratch

Not every brokerage demand becomes a fixed-scope project. Often what's missing is qualified capacity: the internal team knows the business but can't keep up with the backlog, and every direct hire takes months between recruiting, onboarding and the learning curve of the ecosystem.

For that scenario, Espresso Labs offers squad and dedicated developer allocation with professionals already trained in the financial market environment. In practice, that means developers who arrive knowing the map: Sinacor routines and files, B3 integrations, audit trail requirements and the market's operating windows. The time between signing the contract and the first delivery drops drastically, because the sector's learning curve was already climbed in previous projects.

The format also solves the sector's typical peaks: regulatory projects with deadlines set by the CVM or the Central Bank, platform migrations and product launches with a fixed date. The cell scales up during the peak and returns to normal size afterwards, without the liability of hiring and dismissing. Technical management stays with Espresso, and backlog priorities stay with the brokerage.

It is also the antidote to a pattern we know well: projects stuck forever at the "final 10%" for lack of people with ecosystem experience to cross the testing, integration and certification phase.

Why Espresso Labs

Espresso Labs has been building custom software for more than 8 years, with 220+ clients served and more than 57 systems in production under continuous maintenance. In the intermediation sector, our main calling card is the partnership with CM Capital: for more than 5 years we have developed and maintained systems for the brokerage, a successful relationship that has spanned changes in regulation, platforms and the market itself. The portfolio also includes other financial market institutions, such as Vinci Partners, and large-scale operations such as Unilever, C&A and Sabin Diagnósticos.

What we bring to brokerage projects:

• Critical-system culture: we maintain operations that cannot go down, with a ticket pipeline, formal SLAs and monitoring, the same discipline a CTVM or DTVM demands.
• Engineering for regulated environments: versioning, audit trails, access segregation and documentation are part of the process, not optional items.
• Modernization without stopping the operation: we apply incremental modernization to legacy systems, replacing modules in production without a big bang, an essential approach in brokerages, where switching off the old system is never an option.
• Teams to fit: from fixed-scope projects to dedicated squads with professionals seasoned in the financial market ecosystem, integrated with the brokerage's technology team.

Frequently asked questions

What does a software house for brokerage firms do?

It builds and maintains custom systems for CTVMs and DTVMs: investment apps, back-office automation, B3 and Sinacor integrations, APIs, regulatory reports and legacy system modernization.

What is the difference between a CTVM and a DTVM?

Both are institutions licensed by the Central Bank of Brazil and supervised by the CVM to intermediate securities. Since 2009, DTVMs can also trade directly on exchanges, which in practice made the two figures equivalent.

Does every brokerage system need to integrate with Sinacor?

In the vast majority of cases, yes. Sinacor is the back-office standard of the Brazilian market, and new solutions usually read from or write to it. Knowing its routines and files is a basic requirement of any project in the sector.

Does Espresso Labs build home brokers?

We build the experience and integration layers that connect to B3's trading environments and to the market's platforms, experience built over more than 5 years working with CM Capital. The exact scope, from the investor portal to order routing, is defined during the project diagnosis, taking the required certifications into account.
