At Jisc we have been successfully partnering with Wingravity on the Octopus service after they developed a high quality prototype for Octopus. We have been working with Wingravity developers embedded in our own team and they have approached product delivery with great professionalism, we have also benefitted from their knowledge, experience and initiative to improve our product design and internal processes. It has been a please to work with this company and we'd recommend them to others.

Corina is one of those people who enter a team and give their best to motivate people and get projects flawlessly done. I worked with her for almost 2 years and I can wholeheartedly say I have rarely seen such determination, devotion and professionalism. She is trustworthy, kind, a true friend and a skilled technology interpreter. She will make a great addition to any company willing to work with her

Great service and quick processing. Technically everything is perfect so far... I can only recommend it!!!
Bill Malkin
Android/IOS Programmer, Lone Wolf, Australia Author of "Architecture and Engineering in Business and I.T."
Wow, the IT field certainly needs Corina! At the moment it's really just a tekkie boys club littered with countless failed projects. I've found myself working in many large dysfunctional software development projects where all their problems simply came back to abysmal communication. The incredibly difficult task of getting accurate, clear, concise and complete information from the client representatives to the technical staff was sadly neglected and considered a lower priority than getting the technology right. This unsurprisingly, always led to disaster. It's fantastic to see Corina championing the importance of that communication channel, and especially the need to be able to speak to client representatives, designers and technologists, in their own language, to get and pass on information to all who need it.
Morgan Bird
Account Coordinator, Mojo Media Labs, Dallas/Fort Worth USA
I've had a fantastic experience working with Corina! She assisted us with some internal graphic design needs and she was my primary point of contact. She's reliable, detail-oriented, and radiates a positive attitude on a daily basis. Corina ensures that her team fully understands the requirements of the project and has gone above and beyond on all expectations. I would highly recommend Corina and her team and look forward to working with them on future projects.
Ilie Ghiciuc

I've known the team at Wingravity for many years and have done together a few great projects. Their work ethic and their quality is exemplary and we only love working with their talented engineering team.
Diana Enachescu
Founder & CEO Tressori Space
I was lucky to meet the Wingravity team and to start working with them for the implementation of the redesigned interface and new featureas that our app needed. I highly appreciated the timely and precise implementation of the target design, along with the constant communication to ensure alignment. Moreover, I appreciated the raising of identified issues and solutions for improvement, that would make our app more stable and reliable. We consider Wingravity a long term partner, that we can rely on.
Danielle Cocanougher
Vice President, Allcal, Dallas/Fort Worth USA
I've worked alongside Corina for almost 2 years and her team has helped us build several websites from scratch, and refresh our main website's look and feel this year. Corina made the whole process very easy - I was able to leave this major project in her hands and she delivered everything promised in a little over two weeks. I believe it was actually ahead of schedule! Corina was fast to deliver new ideas, answer my questions, and keep me updated on progress. She was understanding of our needs and paid attention to every detail, even offering improvements that we hadn't thought of. It makes such a difference when you know a company is sincere in their efforts to help you create the best website for your company. We are thrilled with our websites and I highly recommend contacting Corina for help building or rebranding your website.

I love supporting smart, heart-centered entrepreneurs who set out to serve their customers well and have a great impact in the world.

We are extremely satisfied with Wingravity's work on our new website. The project was accompanied very professionally from the beginning and the innovative ideas of the Wingravity employees have raised the website to another level. Our employees as well as customers are full of praise and we would implement further projects with Wingravity at any time. We would especially like to thank Corina and Daniel for their tireless support in all aspects of project implementation.

Corina and her team of Wingravity are young, motivated professionals with lots of creative ideas, technical know-how and a solution-oriented work attitude. They have not only successfully redesigned our company website, but also supported us with setting-up our Social Media channels and becoming active in Online Sales and Marketing. The entire team became close friends of Polo and especially Corina always has a good, valuable advice for me when it comes to Online Marketing topics. In the name of Polo Family, I would like to thank you for all your efforts & endeavours for our company – I hope we can keep this great partnership with Wingravity for future projects.

This project - an iOS application for our business - was a dream of mine and I couldn't have brought it to life without WinGravity's assistance. The team is extremely professional and always responsive. I highly recommend WinGravity to anyone looking for a quality app to be developed. Thank you for an amazing iOS application. You guys are awesome, it was a pleasure working with you and I'll look forward to our working together again in the future.

Countries we've delivered for
The principles behind every project, and why founders keep coming back.
Outcomes, not effort
We're measured by what your product does in the market, not by hours logged. Since 2017, we've focused on shipping software that works for the people who use it.
Product-first thinking
Whether you're a first-time founder or a global team, our job is moving your product forward. We optimize for your customers, not our process.
Senior team, no handoffs
The senior engineers, designers, and founders you meet on day one are the same people shipping the code. No bait-and-switch to juniors after the contract is signed.
Built to last
We choose technologies that solve the problem and stay maintainable. No frameworks-of-the-month, no rewrites in 18 months. Just clean, durable code.
Ship every sprint
Working software at the end of every sprint, never a black box that opens at the deadline. Demo, feedback, adapt, repeat.
One team, full stack
Strategy, design, engineering, DevOps, and support, all under one roof. One contract, one accountable team, from first sketch through years of growth.
You own everything
Full source code, full IP, full credentials. We're happy to sign an NDA before we even start talking details. Your product is yours.
Fixed scope, full visibility
A transparent time and cost estimate before we start. You see exactly who's working on what, when it ships, and what it costs. No vague ballparks, no surprise invoices.
More about Wingravity
Our story, principles, philosophy, and the people behind every project
From first idea to launched product
Four phases, full transparency. You always know what's being built, why, when it ships, and what it costs.
Discovery & Estimate
Every project starts with understanding, not code. In discovery workshops we map your product goals, users, technical constraints, and success metrics, then turn them into a transparent time and cost estimate. You know exactly what you're investing in, and why, before a single line of code is written.
// Deliverable: A clear plan and a fixed cost
Statement of Work
We translate discovery into a concrete plan: milestones, deliverables, timelines, and the technology choices behind each one. Whether you choose fixed-scope or a dedicated team, exactly how we'll work together is signed off before kickoff. No hidden scope, no scope creep, no vague ballparks.
// Deliverable: No surprises, agreed up front
Build
We build in short, focused agile sprints with working, shippable software at the end of each one. You see progress continuously, never a black box that opens at the deadline. Clean, reviewed, tested code, frequent demos, and fast adaptation to your feedback keep the product on track.
// Deliverable: Shippable software, every sprint
Launch & Scale
We don't disappear at launch. We handle release, monitoring, and a smooth handover, then stay on for the maintenance, security, and feature work that keep your product secure and evolving as it scales. One accountable partner from first sketch to long after go-live.
// Deliverable: A long-term, accountable partner
Whether you need a fixed-price MVP, a long-term product team, or senior engineers inside your own team, pick the model that fits your stage.
Fixed-Scope project
Best for MVPs and rebuilds with clear scope and a fixed budget.
- Defined scope and milestones

- Transparent statement of work
- Designed, built, and launched end-to-end

Dedicated team
Best for products that need an ongoing partner for strategy, build, and scale.
- A senior team that's truly yours
- Agile sprints, roadmaps, and demos
- Full visibility and reporting
- Flexible scope as your product grows
- Design, engineering, DevOps, and support
Staff augmentation
Best when you need senior React or Node engineers inside your existing team.
- Senior React, React Native, Node.js engineers
- Embedded in your workflow and tools
- Scale up or down on a sprint's notice
- Your process, your tools, your standards
- No long-term lock-in
Meet the people you'll work with
Two siblings, two roles, one mission. Leading every project hands-on since 2017.
Corina Craescu
Co-Founder & CEO
I lead client relationships and product strategy at Wingravity. My focus is making sure every project ships on time, on budget, and solves the problem we agreed to solve. If you're a founder weighing whether to work with us, I'm the person you'll talk to first, and the one who'll stay accountable for the rest.
Daniel Berigoi
Co-Founder & CTO
I lead engineering at Wingravity. I write code, review code, and own the technical decisions on every project we ship. If something's late or broken, you'll hear from me first, and so will the fix. Senior on every sprint, every project, every client.

The questions founders ask us most
Short, honest answers to the questions we hear most often. If yours isn't here, send us a message and we'll answer it directly.
How long does it take to build an MVP?
// Answer
Most MVPs ship in 8 to 16 weeks, depending on scope. We start with a 1-to-2-week discovery phase to lock the requirements, then build in two-week sprints with working software at the end of each. You'll see tangible, usable progress every two weeks, not a black-box reveal at the deadline.
How much will it cost?
// Answer
Every project gets a transparent time and cost estimate before kickoff. No vague ballparks. For fixed-scope MVPs, expect a defined total upfront. For dedicated teams, a clear monthly retainer based on the people you need. The exact number depends on scope; book a 30-minute call and we'll give you a concrete range on the spot.
Who owns the code and IP?
// Answer
You do, fully. On delivery you receive complete ownership of the source code, intellectual property, and all credentials. We're happy to sign an NDA before we even start talking details. Your product is yours.
How do we get started?
// Answer
It starts with a 30-minute intro call to understand what you're building. From there we run a short discovery phase, give you a transparent time and cost estimate, agree on a statement of work, and kick off the first sprint. You can stop after discovery if it's not the right fit, with no obligations.
What's your tech stack?
// Answer
We specialize in React, React Native, Node.js, and TypeScript, backed by serverless AWS infrastructure and PostgreSQL. We pick the right tools for your product instead of forcing a one-size-fits-all stack, but we won't chase the framework-of-the-month at the cost of long-term maintainability.
What happens after launch?
// Answer
We don't disappear at launch. We offer ongoing maintenance, security updates, monitoring, and roadmap work to keep your product secure and evolving as you grow. Many of our launch clients have been with us for years, and the same senior team that shipped your MVP stays on to scale it.
