About ProofSwap
ProofSwap helps indie founders get and display genuine social proof. Give another founder an honest tweet, testimonial, video review, or app feedback to activate your Free exchange-directory listing and meet peers who may be able to help you back.
As of November 11, 2026, 98 social proof exchanges marked verified in ProofSwap's database involve proof accepted by the receiving founder and 44 unique participant accounts (distinct account IDs recorded as a giver or receiver) across all exchange types and the full recorded history, with no rolling date window. This is platform activity, not a customer count or evidence of business results. This aggregate uses publicly readable exchange rows. Its data cache revalidates every 15 minutes, but page and feed caches can delay updates; the as-of date is not a real-time freshness guarantee. The most recent verification was on November 3, 2026. See the aggregate and showcase on the Wall of Proof.
A give-first exchange engine for indie founders to trade visibility and help each other grow.
About the founder
Stefan Rows founded ProofSwap and writes its practical guides. He is a senior software engineer and indie developer.
The exchange path starts when you give first. Help another founder, then your eligible listing can enter the directory. Matches and return replies are not guaranteed. It's not an ad network or a marketplace — it's a community built on generosity.
Why use this?
- •You have a good product but no social proof or reach.
- •It feels awkward asking for favors without offering anything back.
- •Cold outreach for backlinks often gets ignored.
- ✓Lead with generosity — give proof first to activate your exchange listing.
- ✓Get matched with projects that need exactly what you offer.
- ✓Build reputation with verified exchanges and trust signals.
On a live project, embed exchange-verified proof alongside owner-added tweets and written quotes or customer testimonials you approve. The widget updates when eligible proof is added to your wall.

How credits workFrequently Asked Questions
What is social proof exchange?
Social proof exchange is a practice where indie developers and founders trade visibility assets like tweets, testimonials, and video reviews. Instead of paying for ads or cold-emailing strangers, you help each other grow through fair, mutual exchanges. Read our complete guide or explore each exchange type.
Is ProofSwap free to use?
Yes, the core platform is completely free — creating accounts, submitting projects, and making exchanges costs nothing. Optional paid plans protect listings from inactivity-related delisting while subscribed and offer a badge-free embed widget with more display capacity and layouts. Check our pricing for details.
What does "give first" mean?
For the exchange directory, instead of posting a listing and waiting, you start by helping someone else. Find a project that needs what you can offer and give them that proof. An eligible first proof activates your listing; founders you help may later see it in match suggestions, but matches and replies are not guaranteed. Start by finding a project to help.
Do I get a backlink for my project?
Your activated listing has a public project page that links to your site. The link is dofollow once you have given proof to at least one other founder; payment never grants it. Search engines decide whether to crawl, index, or use a page or link in rankings. Participation does not guarantee indexing, ranking benefits, or a permanent backlink.
How are exchanges verified?
When you submit proof (like a URL to your tweet or written testimonial text), the receiver reviews and verifies it. Verified exchanges increase your trust signals and count toward your public exchange record, building your reputation on the platform. See real examples on the public Wall of Proof.
How do exchange credits work?
Your first project is free. Each additional project needs one credit and an open project slot. Verified proof you give earns a credit; receiving proof is free. Free members have one slot initially, two after giving one proof, and three after giving three proofs. Starter allows three projects, Pro ten, and Business has no project cap. Browse projects to get started.
What types of social proof can I trade?
You can trade tweet/post shoutouts, written testimonials, video reviews, and app feedback. Each project specifies what it needs and what the owner can give in return. See all exchange types, browse projects needing testimonials, or read how to get testimonials with zero customers.
Is exchanging social proof ethical?
An exchange can support an honest recommendation when the person has a real experience to describe and chooses their own words. A reciprocal relationship may be relevant to disclosure requirements; check applicable platform rules before publishing. The receiving founder reviews and verifies submitted proof for the exchange record, but acceptance does not establish that an endorsement is unbiased or policy-compliant. A genuine post does not guarantee reach or results. Read our tweet exchange guide and social proof guide for practical examples.
