Altar.io

What Altar.io does

Altar.io is a custom product and software development company headquartered at Rua Adriano C. de Oliveira 4A in Lisbon, Portugal. The site describes the team as startup founders with more than 15 years of combined experience, and its news page says the studio has been building MVPs and scaling startups since 2014. Co-founders Daniel de Castro Ruivo and Paolo Dotta are named on the site. The directory listing records a founding year of 2015.

Six services are listed. Product Scope is a structured 15-day process to align a product vision with business goals. MVP Builder takes a scoped idea to market quickly. Custom Software Development, UX/UI Design, AI Development and Enablement, and Dedicated Teams round out the menu. The dedicated team offer specializes in Angular, React, Node.js, and Python, and the agency says it screens roughly 40 candidates for each hire.

The studio also runs a Seed program, a modular starter covering sign-up, email flows, and password recovery, so projects begin with about half the code in place. Recruiting posts on Hacker News from 2025 describe a remote, Portugal-based team of 40 to 50 people with 14 to 20 developers.

Pricing and engagement

Altar.io publishes more pricing detail than most software agencies. Its pricing page has an estimator by complexity, size, and speed, plus recent projects with cost and duration. Examples include an arts marketplace at 18,000 euros over two months, a community platform MVP at 40,000 euros over three months, a legaltech AI MVP at 100,000 euros over two months, and a proptech AI tool at 350,000 euros over five months.

The contact form sorts inquiries into budget bands below 50,000, 50,000 to 150,000, 150,000 to 500,000, and above 500,000. The agency promises a reply within 24 hours from product and tech experts rather than account managers. Dedicated teams are described as around 40 percent cheaper than hourly project work. The directory listing records $50 to $99 per hour and a $5,000 minimum, well below the published project examples.

Who should hire Altar.io

The strongest fit is a funded founder who needs a product partner to scope, design, and build a first version and then help scale it. Every case study follows the same path: product scope, tech memorandum, clickable prototype, then agile development.

• Fintech and regtech startups, given the Apiax, Synch, Audapio, Synapse Credit, and Quartal Financial Solutions projects.
• Founders who want business advice alongside code. Apiax's CEO calls the team a sparring partner on product decisions, and Fave's founder says the value went beyond scope.
• Companies that want to see prices before a call, since the site lists real project costs by size and complexity.
• Teams that need to hire long-term developers in Portugal, using the dedicated team screening and onboarding process.

Who should look elsewhere

The listing flags premium pricing for senior expertise and says the studio is not ideal for very small one-off projects. The published examples confirm that even a two-month build runs 18,000 euros or more. Hacker News commenters in 2020 also noted that the agency's blog posts were being submitted repeatedly by low-activity accounts, which reads as aggressive content marketing rather than client feedback.

• Buyers with budgets under 18,000 euros, the smallest published project.
• Enterprises that need a large offshore bench. Recruiting posts put the whole company at 40 to 50 people with about 20 developers.
• Teams that want the agency to build without their involvement. The process starts with immersive scoping sessions and expects the client in the room.

Track record and signals

Three case studies carry the most detail. Fave, a fan community app for the music industry, was built with NativeScript, Node.js, Express.js, and MongoDB. The site reports Fave has raised $4.3 million, is backed by Sony Music and Warner Music Group, and was recognized by Fast Company in its 2022 awards for social media companies. Apiax, a Swiss regtech that turns banking regulations into machine-readable rules, was a one-year engagement, and the site says Apiax has since raised $8.1 million and grown past 75 people. Synch, a UK fixed-income data platform, was a one-year build on Angular, Node.js, Express.js, Redis, and PostgreSQL.

The work page lists 17 more projects, including GSMA, EnterpriseBot Rapid, Krepling, MovieMe, OVVIO, Curve, Eye Reach, Hutsi, and two AlixPartners collaborations, REIC and Synapse Credit. Named testimonials come from Philip Schoch of Apiax, Peter Müller of Datahouse, and Jacquelle Amankonah Horton of Fave.

The site links to Clutch, GoodFirms, LinkedIn, YouTube, and the angulartics open source project on GitHub. Case study pages show Clutch scores of 5.0 for Fave, Apiax, and Synch. The agency reports a Clutch Top 1000 listing and a Manifest 2022 global leader award. Google shows a 5.0 rating from a single review.

How Altar.io compares

Against other software agencies in this directory, Altar.io's published project examples make it one of the easiest to compare on total cost, and its Portuguese base puts it between Eastern European rates and US rates. Peers at this level tend to hide pricing behind a call. Its advantages are founder-led product thinking, fintech depth, and three named case studies with funding outcomes. Its gaps are a small team, a Google review count of one, and a listed hourly rate that does not match the site's own numbers.
