Here’s the thing the word “unsecured” makes people believe, and it’s only half true. “Unsecured” means you don’t pledge collateral — no equipment, no real estate, no savings account locked up against the line. That part is real, and it’s worth wanting. But most owners hear “unsecured” and assume it also means nothing personal is on the hook. That’s the part that’s wrong, and on the lender side I watched it bite people who didn’t read closely.
I spent years reviewing line-of-credit applications from inside a lender. Almost every “unsecured” business line of credit I approved still required a personal guarantee — a signed promise that if the business can’t pay, you personally will. No lien on a specific asset, but your name and your personal credit stand behind the debt. So before we rank anything, let me draw the line clearly, because the whole value of this page is that it tells you the truth the ads skip: unsecured ≠ no personal liability.
Unsecured vs. no personal guarantee — they are not the same thing
These two terms get blurred constantly, and the difference can cost you.
- Secured = you pledge a specific asset (collateral). If you default, the lender can seize that asset. Lower risk for the lender, often lower cost for you.
- Unsecured = no specific asset pledged. The lender is lending against your business’s strength and your creditworthiness instead of a thing it can repossess.
- Personal guarantee (PG) = a separate promise, signed by the owner, making you personally responsible for the debt if the business can’t repay. An unsecured line almost always still carries a PG.
So when a lender advertises an “unsecured” line, read it as: no collateral required, but your personal credit and personal guarantee are doing the work the collateral would have done. A genuinely no-personal-guarantee line is a different, much rarer animal — and most products marketed that way come with serious strings. We cover that honestly on Business Line of Credit With No Personal Guarantee. If avoiding the PG is your real goal, start there, not here.

Why an unsecured line costs more (and that’s not a rip-off)
When there’s no collateral to fall back on, the lender is taking on more risk — so it prices for that risk. In practice, an unsecured line tends to carry a higher rate and sometimes a lower limit than a comparable secured one. That’s not a scam; it’s the math of lending without a backstop. The trade you’re making is convenience and keeping your assets free in exchange for paying a bit more.
Whether that trade is worth it depends on your situation. If you’d rather not tie up cash or equipment, unsecured is the point. If you can pledge collateral and you want the lowest cost, a secured line may serve you better. How rates are actually set is its own topic — see How Business Line of Credit Interest Works and Average Business Line of Credit Rates & Fees.
How we picked
We rank by how well each lender serves an owner who specifically wants an unsecured line — no collateral — not by who pays us. For this segment we weight whether the line is genuinely available unsecured, then transparency (especially clear disclosure of the personal guarantee), then true cost and eligibility accessibility, then funding speed and line-size fit. The full method — and our rule that affiliate relationships never set the order — is on How We Evaluate Lenders.
Every pick below also carries one honest negative. A list of lenders with nothing to “watch out for” isn’t a review — it’s an ad.
Best unsecured business lines of credit at a glance
Every figure here is “varies” or carries a verify flag on purpose. Rates, limits, and eligibility for unsecured lines move constantly and differ by lender — we won’t print a number we can’t tie to a live lender source. And remember: “unsecured” below means no collateral, not “no personal guarantee.” Most still require a PG. Confirm current terms with the lender before applying.

The picks, ranked
1. Lendio — best when you want to compare unsecured offers in one shot
Get Funded Today (partner link)
- Best for: owners who want an unsecured line but don’t know which lender will offer one without collateral — and don’t want to apply to six of them separately.
- Watch out for: it’s a marketplace, not a lender. You may get matched to products beyond an unsecured line of credit (including secured options or higher-cost products), so read exactly what each offer requires — collateral and personal guarantee — before you accept.
- Collateral / PG / line size: the no-collateral options exist across the network, but a personal guarantee is typically still required, and specifics vary by matched lender (per Lendio.com, 2026).
- Marcus’s take: “Unsecured” availability is exactly the kind of thing that’s invisible until you apply — one lender will do it, the next won’t, and you can’t tell from the website. A marketplace surfaces that in one soft check instead of a string of hard inquiries that each ding your credit. For this specific question, that’s the efficient first move.

2. Bluevine — best unsecured line for owners with steady revenue
See if you may qualify with Bluevine → (partner link)
- Best for: established-ish businesses with consistent monthly revenue who want a no-collateral line and reasonably fast access.
- Watch out for: an unsecured line generally costs more than a secured one, and revenue consistency matters here — lumpy income may not clear the bar. Confirm the all-in cost, not just the headline rate.
- Collateral / PG / line size: offered without pledged collateral, but expect a personal guarantee; lines run up to about $250,000, with roughly a 625+ FICO, $10,000+ monthly revenue, and 12+ months in business (per Bluevine.com, 2026).* Minimums and limits can change, so confirm current terms.
- Marcus’s take: When there’s no collateral, steady revenue is the security from the lender’s point of view — it’s the cleanest predictor of repayment we had. If your deposits are consistent, you’re a stronger unsecured candidate than you might think.

3. Fundbox — best unsecured option for newer businesses
See if you may qualify with Fundbox → (partner link)
- Best for: newer businesses that can connect a bank account or accounting software, letting the lender underwrite off real activity instead of collateral or a long history.
- Watch out for: the convenience of a short, simple unsecured line can carry a higher effective cost than a bank line — confirm the all-in cost before you draw.
- Collateral / PG / line size: no specific collateral pledged, but a personal guarantee may be required and Fundbox reserves the right to file a UCC lien; lines run up to about $150,000 and tend to be modest early on (per Fundbox.com, 2026).* Confirm current terms before you draw.
- Marcus’s take: Lenders that read your connected data instead of your balance sheet are structurally friendlier to thin-file businesses — and they don’t need collateral because the data is their security. That’s why this tends to be the most realistic unsecured option for a genuinely young business.

4. OnDeck — best unsecured-style line when you value speed
See if you may qualify with OnDeck → (partner link)
- Best for: owners with some revenue history who want fast access and don’t want to pledge a specific asset.
- Watch out for: “no specific collateral” is not the same as “nothing on the line.” OnDeck reports its line of credit is unsecured with no UCC lien (per OnDeck, 2026), but it still requires a personal guarantee — and other lenders in this lane do file a UCC lien (a blanket claim on business assets), so confirm exactly what you’re signing wherever you apply. Speed also tends to cost more.
- Collateral / PG / line size: no specific pledged asset and no UCC lien on the line of credit, but a personal guarantee is required; lines run roughly $6,000–$200,000, with about a 625 minimum FICO, $100,000+ annual revenue, and 1+ year in business (per OnDeck.com, 2026).* Confirm current terms before applying.
- Marcus’s take: This is where “unsecured” gets slippery. A UCC blanket lien means no specific asset is pledged, yet the lender still has a claim on business assets generally. Owners who only heard “unsecured” were sometimes surprised later. Read the security language, not just the marketing.

The catch nobody advertises: the personal guarantee
Let me be blunt, because this is the whole reason this page exists. An unsecured business line of credit almost always still requires a personal guarantee. No collateral on a specific asset — but your signature putting your personal credit and, if it comes to default, your personal finances behind the business debt.
What that means in practice:
- If the business can’t repay, the lender can pursue you personally — the PG is what gives them that right.
- An unsecured line still affects your personal credit in most cases, both at application (a hard inquiry) and if the account goes bad.
- “Unsecured” lowers the asset risk, not the personal risk. Those are two different dials.
If your actual goal is keeping yourself personally off the hook — not just keeping collateral free — that’s a separate search with a much harder answer. Read Business Line of Credit With No Personal Guarantee before you assume “unsecured” gets you there. It usually doesn’t.
The verdict: who an unsecured line is actually right for
Strip away the marketing and it comes down to what you’re really trying to avoid:
- You want to keep collateral free (cash, equipment, real estate) and you’re fine signing a personal guarantee → an unsecured line is exactly the right tool. Start with Lendio to see who’ll offer one, then compare Bluevine, Fundbox, and OnDeck on all-in cost for the line size you need.
- You have steady revenue → Bluevine is worth a direct look; revenue is your security when there’s no collateral.
- You’re a newer business → Fundbox tends to be the most realistic unsecured option, since it underwrites off connected data.
- You want speed → OnDeck, but confirm the UCC/PG language first so “unsecured” doesn’t surprise you.
- Your real goal is no personal liability → an unsecured line probably won’t get you there. See the no-personal-guarantee guide instead.
The most common mistake I watched owners make with unsecured lines wasn’t choosing the wrong lender — it was assuming “unsecured” meant they had no personal skin in the game, then being blindsided by the guarantee when something went wrong. Know what you’re signing. Then sign it.

Frequently asked questions
What is an unsecured business line of credit?
It’s a revolving line of credit you can draw from, repay, and draw again — without pledging a specific asset (like equipment or real estate) as collateral. Instead of securing the line against a thing it can repossess, the lender extends it based on your business’s strength and your creditworthiness. Because there’s no collateral backstop, unsecured lines tend to carry a higher rate and sometimes a lower limit than comparable secured ones. Exact terms vary by lender and change often.
Do unsecured business lines of credit require a personal guarantee?
Almost always, yes — and this is the key thing the word “unsecured” hides. “Unsecured” means no collateral on a specific asset; it does not mean no personal liability. Most unsecured business lines still require a personal guarantee, a signed promise making you personally responsible if the business can’t repay. A genuinely no-personal-guarantee line is rare and usually comes with serious conditions. If avoiding the guarantee is your goal, that’s a different search — see our no-personal-guarantee guide. For the lenders on this page, a personal guarantee is required at Bluevine and OnDeck and may be required at Fundbox (per each lender’s published terms, 2026); always confirm the current requirement before you apply.
Who offers the best unsecured business line of credit?
There’s no single “best” — it depends on your profile. For comparing options without applying one at a time, a marketplace like Lendio lets you see who’ll offer an unsecured line in one soft check. For owners with steady revenue, Bluevine is worth a direct look; for newer businesses, Fundbox tends to be the most accessible; for speed, OnDeck (confirm its UCC/personal-guarantee terms first). The right pick is the one that offers a genuinely unsecured line at a cost that fits your situation — and the specifics vary by lender, so confirm current terms before applying.
Is an unsecured line of credit more expensive than a secured one?
Generally, yes. With no collateral to fall back on, the lender takes more risk and prices for it — so unsecured lines tend to carry higher rates and sometimes lower limits than comparable secured lines. The exact difference varies by lender and by your credit profile, so we won’t print a number. The trade you’re making is keeping your assets free in exchange for paying a bit more. See Secured vs. Unsecured.
Will applying for an unsecured line hurt my credit score?
A formal application typically involves a hard inquiry, which can temporarily ding your personal credit — and applying to several lenders at once stacks those up. Because most unsecured lines carry a personal guarantee, the account can also affect your personal credit over its life. Marketplaces like Lendio let you check your options with a soft credit pull that doesn’t affect your personal credit score, then only trigger a hard inquiry at underwriting if you accept a lender’s offer (per Lendio.com, 2026). Individual lenders vary, so confirm each program’s current terms before you apply.
