Zulbera vs Toptal vs Gun.io vs Arc

You’ve Googled “Toptal alternatives.” You’re trying to figure out whether to use a talent marketplace, a freelance platform, or a full-service software studio. This guide is the honest version — written by a studio founder who has lost work to Toptal and won work back when founders realised what they actually needed.

This is not “why Zulbera is best.” All four models work. They just work for different problems.

The four models, at a glance

	Toptal	Gun.io	Arc.dev	Software Studio (e.g. Zulbera)

Pricing	$80–$200+/hr	$100–$180/hr	$50–$120/hr	€25k–€500k+ fixed scope
Vetting	Top ~3% global	Top ~5% (US-focused)	Mid-tier vetting	Senior-only, in-house
You manage	Each contractor	Each contractor	Each contractor	One studio counterparty
Coordination	Your job	Your job	Your job	Included
IP & contracts	Per-contractor	Per-contractor	Per-contractor	Single MSA
Accountable for outcome	No	No	No	Yes
Warranty	Replace contractor	Replace contractor	Replace contractor	Fix defects in warranty period
Best for	Scaling roles	Long-term placements	Cost-conscious senior hires	Non-technical founders, new products

What each model actually delivers

Toptal

Toptal places individual senior freelancers — engineers, designers, project managers, finance specialists. The pitch is “top 3% of talent.” The vetting is real: live coding interviews, English assessment, soft-skills evaluation, and a paid test project. The result is a roster of capable senior contractors.

What Toptal gives you:

• Access to a curated talent pool you couldn’t easily recruit yourself
• Fast time-to-start (often 1–2 weeks from request to first day)
• A talent matcher who narrows the pool for your role
• Standardised commercial terms across all engagements

What Toptal does not give you:

• A team that works as a coordinated unit (each contractor is independent)
• Product or design judgement at the engagement level (each contractor has their own opinions)
• Accountability for delivery (Toptal’s accountability is to provide qualified contractors, not to ship a product)
• Architecture or technical leadership unless you specifically hire a Tech Lead role
• Fixed pricing — Toptal is exclusively hourly or weekly

Toptal works brilliantly when you have a technical leader in-house who can coordinate work. It is dangerous for non-technical founders, because the coordination cost — which is invisible at signup — becomes the largest expense.

Gun.io

Gun.io is structurally similar to Toptal: a vetted marketplace for senior developers. It has a smaller community, a more US-focused base, and a culture that emphasises longer engagements rather than gig-style work.

Where Gun.io differs from Toptal:

• Smaller talent pool (an advantage if you want consistency, a disadvantage if you need niche skills)
• Stronger US time-zone coverage
• Slightly more community feel — Gun.io developers know each other, which can be useful for assembling small teams
• Comparable rates ($100–$180/hour for senior engineers)

Gun.io is a fine alternative to Toptal. The decision between them is largely cultural — whether you prefer the larger global marketplace (Toptal) or the smaller community-feel platform (Gun.io). Neither owns delivery.

Arc.dev

Arc (formerly CodementorX) competes on cost and remote-only positioning. Its talent pool skews to Eastern Europe, Latin America, and Asia, with hourly rates substantially below Toptal and Gun.io ($50–$120/hour for senior contractors).

Where Arc differs:

• Lower rates by 30–50% vs Toptal
• Less rigorous vetting — quality is more variable across the pool
• Remote-only positioning (Toptal also offers this; Arc commits to it)
• Strong fit for ongoing contractor needs rather than one-off projects

Arc works best for founders who have technical leadership in-house and need cost-effective senior contractors for specific roles. It is not a good fit for founders without technical leadership, because the variability in vetting means a hiring miss is more likely, and the coordination cost is the same as with Toptal or Gun.io.

A software studio (Zulbera and similar)

A software studio is fundamentally different from a marketplace. A studio is one entity, with one counterparty relationship, one MSA, one warranty, one delivery commitment.

What a studio gives you:

• Architecture, design, engineering, QA, DevOps, and project management as one coordinated team
• A single accountable party for the entire delivery
• Fixed-scope or fixed-tier pricing (you know the cost before you commit)
• Continuity of team across the project lifecycle (the people who design the architecture also implement it)
• A defined engagement model: discovery → build → launch → support
• Product judgement and senior technical opinion built into the engagement, not bought separately

What a studio does not give you:

• Ability to hire one senior backend engineer for 3 months at $150/hour (studios don’t unbundle that way)
• The flexibility of swapping contractors in and out at will
• The lowest possible hourly rate (you’re paying for coordination and accountability)

Studios are best for non-technical founders, first products, full-rebuilds, and any situation where the founder values having one party accountable for shipping the outcome.

Real cost comparison: 6-month MVP

Let’s compare the four models on a realistic scenario: building a B2B SaaS MVP over 6 months, requiring backend, frontend, design, QA, and DevOps.

Toptal (senior contractors)

• Backend engineer: $160/hour × 30 hrs/week × 24 weeks = $115,200
• Frontend engineer: $150/hour × 25 hrs/week × 24 weeks = $90,000
• Designer (part-time): $140/hour × 15 hrs/week × 16 weeks = $33,600
• QA (part-time): $100/hour × 12 hrs/week × 20 weeks = $24,000
• Founder coordination time: 12 hours/week × 24 weeks = 288 hours of opportunity cost
• Subtotal: $262,800 + 288 founder hours

Gun.io

Similar arithmetic — slightly lower hourly rates on average:

• Estimate: $235,000 + 288 founder hours

Arc.dev

• Backend: $100/hour × 30 hrs/week × 24 weeks = $72,000
• Frontend: $90/hour × 25 hrs/week × 24 weeks = $54,000
• Designer: $80/hour × 15 hrs/week × 16 weeks = $19,200
• QA: $60/hour × 12 hrs/week × 20 weeks = $14,400
• Founder coordination time: 14 hours/week × 24 weeks = 336 hours (more, because vetting is weaker so more decisions land on you)
• Subtotal: $159,600 + 336 founder hours

Software studio (Zulbera engagement)

A 6-month SaaS MVP with the same scope is a fixed-price engagement:

• Discovery + architecture (3 weeks): €15,000
• Build phase (16 weeks): €110,000
• Launch + handover (3 weeks): €15,000
• Founder coordination time: 3–4 hours/week × 22 weeks = 66–88 hours
• Total: €140,000 (~$150,000) + 88 founder hours

The studio is the cheapest option if you value founder time, even before accounting for delivery risk. The studio also includes coordination, design judgement, architecture decisions, and warranty — all of which are unpriced extras in the marketplace models.

Where each model wins

Toptal wins when:

• You have a technical co-founder or senior tech lead in-house
• You need to add one or two specific roles (e.g., “we need a second senior React engineer for 4 months”)
• You can afford to spend 10+ hours/week coordinating contractors
• You want flexibility to ramp the team up or down quickly
• You have product judgement covered — you just need execution capacity

Gun.io wins when:

• You want a slightly smaller, US-time-zone-aligned community
• You prefer longer engagements over gig-style placements
• You value community continuity (Gun.io engineers tend to recommend each other)

Arc.dev wins when:

• Budget is tight and you have technical leadership in-house
• You’re comfortable with more variable vetting in exchange for 30–50% cost savings
• You need ongoing contractor capacity rather than project delivery

A studio wins when:

• You are non-technical and need a partner to own the product
• You are building a first SaaS product where architecture decisions matter
• You want fixed-cost certainty before committing
• You want one accountable party for IP, warranty, and delivery
• You value your founder time at more than $100/hour and want it preserved for sales and strategy
• The product requires design, architecture, engineering, and QA to be coordinated as one unit

The honest comparison founders miss

The Toptal vs studio comparison is usually framed as “freelancers vs agency.” That framing misses the real difference.

Toptal, Gun.io, and Arc sell hours. A studio sells outcomes.

If you can convert hours into outcomes yourself — because you have technical leadership in-house — marketplaces are the cheaper unit cost. If you cannot convert hours into outcomes yourself — because you’re non-technical or this is your first product — a studio is the cheaper outcome cost, even when its hourly equivalent is higher.

This is also why the post-engagement experience differs so much:

• After a Toptal engagement, you have the code, the people are gone, and any post-launch issues are your problem (unless you keep paying the contractors hourly)
• After a studio engagement, you have the code, the team is still available, documentation exists, and the studio has a warranty period covering defects

Neither is universally better. They solve different problems.

How to decide between them

1. Map your situation honestly. Are you a technical founder, a non-technical founder with a tech lead, or a non-technical founder alone? This is the single most important variable.

2. Calculate the founder-time cost. Add 10–15 hours/week to any marketplace engagement for coordination overhead. Multiply by your time value. Add that to the headline cost.

3. Quote the same scope from both models. Send the exact same brief to Toptal/Gun.io/Arc and to two studios. Compare apples to apples: what is included, what is excluded, what the warranty covers.

4. Verify accountability terms. Ask each provider: “If the deliverable does not meet specification, what happens?” The answer reveals the model.

5. Start small. Whatever you choose, start with a 2–4 week paid engagement. Use it to verify communication, technical judgement, and accountability before committing to a 6-month build.

When founders switch — and why

A common pattern: a founder starts with Toptal or Arc to save money, hires two contractors, then realises after 6–8 weeks that:

• Coordination is taking 15 hours of their week
• Each contractor has a different opinion on architecture
• There’s no single owner of the design system
• QA is falling through the cracks
• They’re spending more time managing than selling

At that point, they either hire a fractional CTO (€5,000–€10,000/month) to provide the missing coordination, or they switch to a studio engagement.

The reverse also happens. A founder starts with a studio, builds the MVP, and after launch wants to add capacity to ship features faster. They retain the studio for architecture decisions and bring in Toptal contractors for execution.

Use the right tool for the right phase. Marketplaces and studios are not enemies — they are complementary tools at different stages.

What Zulbera actually is

For the founders comparing us specifically: Zulbera is a senior-only software studio. We take on 6–10 client engagements per year. Every engagement starts with a paid 2–3 week discovery sprint where we evaluate fit before either side commits to a full build. We sign a single MSA covering IP transfer, NDA, warranties, and code ownership. Our typical engagement is €25,000–€500,000 fixed scope. Our average client retention past launch is 70%+ — most clients stay on as monthly retainer relationships for ongoing development.

We are slower to start than Toptal (3–4 weeks vs 1–2 weeks). We are more expensive on an hourly equivalent. We are the wrong choice for staff augmentation. We are the right choice when you want one accountable party to ship a product end-to-end.

If that’s what you need: start a conversation.

If not, Toptal, Gun.io, and Arc are all legitimate options for the right founder.
